Proof of concept... #360 TRIDENT as seastar survey tool!

Before embarking on any adventure, I like to complete a proof of concept for whatever shenanigan I am up to. In this case, it is testing the OpenROV TRIDENT as filmmakers assistant and #360video survey tool.

This Monday I got to do something i've been dreaming of for over a year now! I got to test out shooting 360 video with a TRIDENT ROV!

In preparation for the coral bleaching and restoration portion of the film, Cloudbreak, it became clear that being able to survey larger areas of the reef before jumping in with the 360 cameras would be super helpful. So I figured, why not do double duty and do a quick Seastar wasting syndrome survey while we were at it!

Last time we surveyed the Passenger ferry pier at Cove 2, we noted basically zero seastars and a multitude of tiny urchins. This time... No stars, and no urchins.

I'd chatted with Zack from OpenROV about catching up when he was in town, but we hadn't really nailed down and exact date until last week. I'd been wracking my brain about 'optimal' set up for a 360 flying ROV. Would it be pole out front, would it be the 3 camera array mounted on top, the options were numerous.

In the interest of efficiency and utilizing stuff I already had sitting around the house (and limited options on hand for mounting brackets etc) i figured why not give the method that Kodak Pixpro already uses for flying on aerial drones. With the original OpenROV that wouldn't be a real option due to shape, but with the new TRIDENT, its slim and trim design could work.

So we opted to use the standard mounts (luckily I found two in my random accessories drawer) one on top, one on the bottom and hope for the best. I knew going into it that the stitch would be a bit of a challenge, considering loss of FOV with the small dome ports and parallax from the distance between cameras (less of an issue on a drone because everything is so far away) but figured if this is just for surveys and not for client footage, that what the heck, why not do a proof of concept!

With Zach and Dominic in town, there was no better time than the present! We met up at Cove 2 as the passenger ferry was fortuitously not running, and got started! Introductions to the Trident were made, if you are familiar with the earlier generation OpenROV, this is basically worlds apart. The TRIDENT really is what the Phantom Drone was for aerial, it is stunning. The build quality is top shelf, it is robust and magnificently easy to master the controls. This immediately boosted my confidence.

Once the cameras were securely mounted on the TRIDENT we removed the saltwater weights as the Kodak Pixpro's are a little negative and got started!

The trim compensation worked well to level the TRIDENT out, even though she was nose heavy from the cameras, in future tests I'll probably make some little syntactic foam floats for the top camera, as although trim compensation worked well, I'd like to keep her floating in trim comfortably as that makes for more stable footage which is necessary for a good 360 viewing experience.

We flew the TRIDENT #360 around for a good half an hour which was a blast. Again, if you have only experienced the earlier models of OpenROV, you REALLY need to give this a try, seriously night and day. Sadly my lenses fogged up on the Kodak housings (humidity and all can be a bear in the summer) but luckily I still managed to get a fair bit of usable footage which will be uploaded shortly.

While you are waiting, here are a few pictures!

We are currently using pix pro 360s in our underwater meteorite hunt! Very interested in your attachment process and outcomes. Also let us know if you find any remedy to fogging!

SSWS is still active in Mid Puget Sound. Leather stars are prevalent (they are more resistant to the virus) and there are small sunflower stars but no medium or large. When small sunflowers reach a bit larger than hand size they seem to contract the disease and waste away as seen at the end of this video. The mystery six armed star makes another appearance :)

Thanks for sharing Laura. And thanks for all the good work you continue to do!

Does the virus have any correlation with Demoic Acid from red tide? asks my electrical engineer friend Pete.

This little boat wreck "the Honeybear" at cove 2 used to be covered in sea stars of numerous species. Now as you can see there is one lone mottled star calling it's decaying hull home.

Love the 360 video. Wish this tech was around 5 years ago so we could have before and after.


I'm testing the use of 360 video as a method of doing Seastar surveys. 360 video can give an immersive experience and allow more time to 'look around' at a site after the initial dive.

Please watch in YouTube in 4K for best viewing experience!

Continuing to explore new ways to communicate the underwater world of the Emerald Sea, we had the opportunity (huge thanks to to test out a 360VR system to film a recent storm drain excursion and seastar survey. I have not completed stitching the 360 footage together yet but in the meantime here is a short "making of" video for your enjoyment. You will see a couple of Pisaster in the video, but for the most part, we are not seeing recovery of Pisaster or Pycnopodia at my survey sites :(

Can't wait to see that Laura!! I'll be up in Port Angeles and Bellingham this week, any chance you'll be near the Peninsula?

If you are a scuba diver or OpenROV pilot and notice urchins with their spines falling off, please or (any of these will work) to an instagram picture of the beach where you observed it and note in the comments what you observed. Make sure location services is on so that your post will be geotagged.

Please continue to report on seastar wasting disease as well, as with summer coming we are expecting to see an uptick in the disease.

This is such a bummer. We'll help spread the word though! Is there a recent map showing the extent of seastar and urchin wasting by location?

We will now also be keeping an eye out for Urchin wasting

Oh no! Are there any citizen science programs springing up around this? Or the plan is to just report any findings?

We are continuing to report findings to the same scientists that are working on seastar wasting. They feel its same virus. Because urchins are underwater it will be up to scuba divers and OpenROV pilots to do the reporting!!!!

Yikes, I didn't realize they sea urchins were having problems too :(

Because kids love UW robots and Lasers! OpenROV helped me share this project with kids from Summit Academy and it seems to have made an impression... Thank you OpenROV, OpenExplorer and Mr. Spencer!


This is so fantastic Laura!

A recent dive at The Alki Junkyard... thinks may be looking up!

Short 'week in review' when I got out with Summit Academy students. We saw and measured a couple mottled stars in the 4" size.

More diving less talk :) Surveying the Alki Junkyard nearshore for Sea Stars... Verdict... No stars on the shallow pilings :( No sunflower stars in the eelgrass beds. (we used to see them here and there)

Visited the Alki Junkyard in West Seattle spent a fair bit of time investigating a set of pilings from an old pier that used to be covered in Sea Stars. No sea stars on the pilings and no sunflower stars or mottled stars in the eelgrass bed or on the top of the shelf before the slope. There was a fair bit of current and i had almost all my cable out which had a bit of drag. Looking forward to getting back out during or closer to slack.

Seastar wasting disease has hit Constellation Park (Alki Point) in West Seattle very hard. In 2011 beach naturalists counted >600 pisaster in a set transect within the park boundaries down to a -2 tide. This fall their counts were showing all time low at 28 pisaster counted within the park boundaries.

It is no wonder that I found zero Pisaster on the intertidal rocks on my first exploration of this site with my OpenROV.

Laura, this is great!
how do you make your cool animated logo?

I do super simple animation (like in this video which was just simple key framing) in Final Cut Pro X. For more advanced stuff I use Adobe After effects or some FPCX 3D and/or wireframe plugins.

After a long week or two of freezing weather and a big bad norwester storm passing through I finally got out to survey a new site! Because we have topside data on Constellation park, I decided to survey the large rocks and boulders in the near shore. I knew I wouldn't find much, but I was more interested in "could I find the boulders and investigate them" to which the answer was a resounding YES! With the repairs completed I was able to hold a steady course today which helped when running a grid pattern. I was able to find large rocks and descend on them and visualize a lack of sea stars, where there once would have been numerous individuals.

I deployed at the base of the ramp that leads to the beach. I did not make it over to the rocky reef to the left (which leads to the opening of a large pipeline) but still was able to visit a nice rocky area approx 200' off shore and to a max depth of about 15'.


On my last outing with the OpenROV, I noted that steering seemed a bit wonky. I attributed it to my poor piloting skills but as luck would have it, it seems it was not my fault (this time).

After attempting to re-callibrate and re-program the starboard ESC I noted it acting glitchy. Even my minimal knowledge of electronic-y type stuff knows that glitchy acting stuff can mean a wire that has a bad connection, or too much connection to something it shouldn't.

Luckily I have an iFixit set which has exactly the right size driver for the ESC, and i had it open in no time flat. What to my wondering eyes should appear but two of the wires had bare spots. I pulled out the liquid electrical tape and sealed them up and voila! all better!

Of course now my servo is giving me a bit of grief but I'll leave that for another day :)

To help my steering and also in the case of letting kids drive I picked up a Logitech F310 gamepad. So far its been plug and play, i spent a bit of time after the fixing of the wiring to sort out this new fangled accessory. Talk about gamification!


Nice work Laura! Nothing like having a solid field kit for anyone working in marine tech.

Say, I'm coming back to WA last week of December, anything planned for your expeditions that week? If no, I'm planning to dive ROVs on these 1920's sunken cars in Port Angeles... tempted ???

I'll be out surveying stars and stormwater every free day! Also want to go take a look at the green urchin population that has moved in at the passenger ferry pier.

For comparison we went out later in the day on scuba with our cameras, here is same sea star. Its not a fair comparison really, as I shoot with a Sony EX1 in a Gates housing with a Fathom dome port, and my OpenROV was a bit fogged up.

In general though, the ROV did a good job. I found one other large Pisaster on scuba that i did not manage to see with the ROV, but that is due to some steering problems I encountered due to a wire short in my starboard ESC. (problem now fixed)


Screen grab of video shot with OpenROV at one of our transect sites.


How are you doing the transect sites with the ROV? Are you getting GPS location them diving and heading a prescribed amount?

Hi Paul, we are covering well known underwater landmarks that i have scuba dived previously. I chose 'the face of the outfall' 'the rocks out to the outfall' Piling set 1,2,3,4,5,6 etc.. The reason I made this decision was so that I could just make a map of the transects as opposed to marking the transects underwater. We do have some lines underwater to follow, but again, i wanted to make this as easy and repeatable as possible for diver and ROV pilot alike :)

is still working it's magic. Last night after our Whale Trail monthly Guest Speaker Series, one of the long time volunteers who has been doing sea star counts out at Constellation park in West Seattle for many years gave me an update.

The news wasn't so good, there are fewer and fewer pisaster and they are still showing signs of wasting disease even though the weather and water has cooled off dramatically. There are some sunflower star and mottled star recruits but they still don't seem to be maturing past about 4-5 inches in diameter.

On the bright side, when I sent the data in to Dr. Harvell not only was she very grateful for the observations, but she said that the paper we've all been waiting on with baited breath should be published next week!!! Finally, some answers are coming... I don't expect we'll have solutions, but answers will help...

I'm hoping to get out to the same site and investigate with my OpenROV in the next few days to investigate the sub-tidal. Then will compare with scuba at same site to judge efficacy of sea star surveys with OpenROV.

That's so great to hear (that the citizen science component is working, not that the sea stars are dying). I'm eager to hear how the transect data comparison goes. Will also be eager to hear how it goes with a 2.7 once we send you one of those.

More Sea Trials and looking for Baby Sea Stars... Sadly none to be found in the nearshore at Cove 1

The end of the video is Amazing. Things learned:
Tether too floaty
New Cockpit is Cool
Deploying with drifwood sucks
C-stand and Umbrella work like a charm
Need to move battery pods back slightly

LOL :) Ya, i'm trying to make them 'watchable' from a learning point of view (even at my own expense) Glad you like it!

Great video! How far from the shore did you go and how deep?

Searching for baby sea stars in the nearshore at Cove 1. No luck. None on the pilings either.


Searching for baby sea stars in the nearshore at Cove 1. No luck. None on the pilings either.


Was able to do a bit of investigating on a rocky reef that covers a stormwater outfall which used to have numerous sea stars on it. Still learning to drive the ROV and sorting out buoyancy of the tether, but was able to visualize a few sea small sea stars.


Nice shot Laura! I think I can even see a small yellow sea star in this photo, just to the left of the starboard battery pod end cap?

P.S. Genius idea with the 5 gallon bucket for tether and ROV together.

Ordered up a TP-Link TL-MR3040 portable AP wireless router so for less convenient sites can just use my iPad for investigation.

read more about setup:

I won't be using a pelican for now but do have some laying around so may go that direction

Difference between fresh and salt?


syntactic foam floats for buoyancy...


Are you carrying a heavy payload? I usually am fighting too much buoyancy!

Just saw the previous post, did you create the new tubes? Looks great :)

Yes, we created new battery pods and end caps. They are more robust. We also milled portions of the e-chassi end caps.

Glued some bits of syntactic foam to my @OpenROV to help counteract the slightly larger, denser batteries... (went with NiMH's vs LiPO)

two of the StiX's arm floats work perfectly and the inner inserts (for my ultralight arms that hold them in place seem to make the difference between salt and fresh (or I can stuff a couple corks in the holes) :)


Took hull #1265 out for a quick dip in Puget Sound (aka Saltwater) to see how she floats/sinks. Juuuust neutral to slightly negative in the top 2' of water (which is pretty fresh right now, so i suspect at depth she'll be perfect.

Best line management system yet. Sometimes clever = simple. Doubles as a rinse bucket, keeps car dry, etc...


She's ALIVE!! Hull #1265 is alive!!!!

Congratulations on your successful confined water trials. Sea trials are not far off now... :)

Our voices have been heard in Washington D.C.!!!

Puget Sound Recovery Caucus proposes bill to find solutions to sea star wasting syndrome and other marine disease emergencies
Congressman Denny Heck unveils Marine Disease Emergency Act to establish official emergency process through the National Oceanic and Atmospheric Administration

WASHINGTON, D.C. – To address the sea star wasting syndrome and other major marine disease emergencies, this week Representative Denny Heck (WA-10) and the Puget Sound Recovery Caucus introduced the Marine Disease Emergency Act. The proposed legislation would establish a framework for declaring and responding to a marine disease emergency, and to provide the science community with the resources to proactively protect marine ecosystems from being irreparably damaged by cascading epidemics.

The Marine Disease Emergency Act establishes a declaration process for the Secretary of Commerce, acting through the Administrator of NOAA, to declare a marine disease emergency. The proposed bill outlines the factors needed for a 120-day rapid response plan, including the necessary engagement of individuals and entities at federal, regional, state and local levels to assist in a coordinated and effective response aimed at minimizing the impacts and preventing further transmission. The legislation also requires a post-emergency report detailing current disease status and providing recommendations for improving responses to future marine disease emergencies.

The Marine Disease Emergency Act establishes a national data repository to facilitate research and link different datasets from across the country, as well as a “Marine Disease Emergency Fund” under Treasury in order to accept donations from the public and the industry.

“Sea stars do not function underwater in a vacuum,” said Representative Denny Heck, who represents the South Puget Sound area. “They are in fact a keystone species vital to the ecosystem. When these species face an epidemic, we must engage the scientific community in an organized, rapid-response approach to determine what can be done to halt the damage to our oceans. This could be a sign of a deeper problem.”

Professor Drew Harvell of Cornell University, who studies the ecology and evolution of coral resistance to disease, expressed support for the new policy, saying "Disease outbreaks of marine organisms are predicted to increase with warming oceans and so it’s very welcome to see legislation like the Marine Disease Emergency Act introduced."

"When you pierce the surface of our picturesque water vistas, what's underneath is not OK. We have sea stars that are wasting away, pulling themselves apart and limbs disappearing from their bodies. That is not OK. And it's only getting worse," said Sheida Sahandy, executive director of the Puget Sound Partnership. "We need the ability to respond to these kinds of emergencies as quickly as we would an earthquake or a hurricane. This action creates the support for the kind of nimble response that is required in order to react to fast-acting threats to our ecosystem."

Representatives Heck and Kilmer co-founded the Congressional Puget Sound Caucus last year to reflect their commitment to preserving the Puget Sound. The caucus is the only Congressional working group devoted exclusively to promoting Puget Sound cleanup efforts, and builds on the legacy left by former Congressman Norm Dicks, a longtime advocate for the health of the Puget Sound. The caucus continues to be focused on promoting the three region-wide Puget Sound recovery priorities: preventing pollution from urban stormwater runoff, protecting and restoring habitat, and restoring and re-opening shellfish beds.

Wow!! This is really big news. Citizen science FTW. Hopefully that continues to be an aspect of this increased effort.

Fantastic Laura!

Hey Laura! Have you found any young sea stars? Is the population starting to rebound?

There are the same number of 'babies' as when you were here. There are recruits, but they seem to die when they reach hand size. Still no pisaster recruits and minimal pycno :(

Check out this great video by award winning filmmaker Michael Werner on DiverLaura's citizen science work on behalf of the Sea Stars...

I'm giddy with excitement, i just got the tracking number for my rechargeable batteries (ordered from battery space) and it looks like they may be arriving TOMORROW!!!!!!!!!! I <3 Fed Ex!

Tomorrow I will be meeting up with Erika Bergman and Christine Spiten to see how an ROV survey compares to a diver survey.

Additionally i'm very excited to shoot some video of the OpenROV's underwater whilst they run transects.

We will be meeting at the site i've been documenting for the past year (Seacrest Cove 1) which as of the last couple weeks has been showing an uptick in wasting disease in the mottled sea star recruits.

Excited to see video!

Did you get any further with this? Some of our senior students are working on this very topic for their project and it'd be awesome to share the data with them.

Hi Paul, yes!! I got out on my first successful survey yesterday where I followed with a scuba dive. I'm editing the video now to show the efficacy. I think it is a great option for a general site overview, as in you can get a quick idea of:

1) sea stars present: y or n
2) species present: Pisaster, pycno, etc...
3) size of sea stars present: Large or small
4) general density of visible sea stars on transect.

It can't see under a rock/nook/cranny quite as well as a diver, but it can give you an idea if the site is experiencing recovery or there are a few potentially resistant adults, etc...

An article I co-authored with the AMAZING Dr. Drew Harvell last year about sick sea stars and starless nights.

My ROV is SO CLOSE to being done. Just doing pressure testing to the e-chassis and battery tubes over the weekend. Ordered some sweet NiMH cells (and made battery tubes to fit them) so just waiting for them to arrive and then we can commence with Sea Star Wasting Syndrome Surveys.

Went out on Scuba a couple days ago and noticed that although there were lots of baby mottled stars, that they are dying before they reach full size. :(

Great to hear about the ROV - very sad to hear about the mottled stars.

This wednesday hope to shoot some video with Erica and Christen surveying with their OpenROV's at one of my sea star wasting syndrome survey sites. Figure it would be very good to have a baseline video by diver to compare ROV survey with. Also have some sweet footage both uw and topside of the project!

Moar images uploaded!

testing electronics and programming motors today! Wish me luck!

Luck! Also: you're not using C batteries are you??

lol.. those are my cohort in crimes idea... 8 of questionable age couldn't handle the draw so we went back to the big lead acid testing batteries.

Looking good... You are quite the engineer.... :) For your next project, should you accept it... Design and build a discreet water sampler that will fit on the OpenROV.... :)

Looking at your pictures, it appears that the electric thruster motors remain open to the water (as in the internal windings, etc.. get wet). Is this correct?

This is the design per OpenROV. We replaced the ball bearings with brass bushings, and dipped the critters in a sealant to saltwater proof as best we could, but i don't expect them to be incredibly long lived even with the fresh water rinse tub I have set up. These are more of a fresh water ROV from this perspective.

Cool. Thanks... :)

Spaghetti anyone?

Wirepoluza started tonight.

Got four wires of the IMU moved over into the 4 inch tube, but used THE WRONG CONNECTOR... Male vs. Female. oops.

Not an issue, just fifteen minute redo.


The sea star wasting syndrome has now been observed all the way out to Neah Bay. Waiting to hear back of Tatoosh is impacted. Tatoosh island is where Dr. Paine's original keystone species work was carried out.

Read more about that here:


We have some OpenROVers in that area. Can you make a map of places that would be good to test? I can rally the team!

I'll put something together tomorrow... Basically starting at port angeles and heading west. Anyone on the Canadian side?

Hey Laura, I'm around this week and the week after August 24th. Wanna plan something for late august?

I just talked with a local guy here in PA who runs a kayak operation. He says he and his students have been seeing wasted sea stars on nearly all of their trips. He want's to help. Wanna team up?

Yes, teaming up with kayakers would be fantastic!!!! If he could take a look at and enter locations (either with or manual entry) or email me of the locations they've seen them, I'll get them entered on the map.

and Yes! lets plan for late august, i'm a bit swamped right now but things lighten up in a couple weeks :)

hahah totally weird triple-quadruple post bug

Yesterday I persevered soldering the ESC's to the board. My mentor and electronics teacher decided that the wire used in them was not ideal and the solder actually needs to be on the top of the board as opposed to underside, as the connection to the circuit is what needs to be soldered. These little motors are high draw so having best connection possible is ideal. So I get to do more soldering today :). I'm not complaining mind you, I'm delighted for opportunity to learn and improve...

Here is the latest update... I'm heading back over in a bit to resolder..

The craptastic wiring on all three ESC's has been replaced with Mil-Spec. silver/copper Teflon coated wire and low temperature (normal 60/40) solder.
They used a low lead solder witch raises the melt temps. to very high levels, which is very bad for electronics. Good for home water pipes.......

In addition to that the little PCB's are thick copper for high heat transmission, so they were a handful to rework.

The three units are ready to be soldered back on to the main board.

I love how you can tell most of these photos were taken by someone with a real eye for photography. Some of these are very glamorous ROV pictures :)

Soldering today, and a bit of electronic testing...


We started first round of testing electronics today... servo motor, check! lights, check! motor controller, Check!

Also looking at some ways to improve the design and potential longevity of the system.

1) brass adaptors for prop <-> shaft interface
2) removed the steel ball bearings and replaced with brass bushings (puget sound is saltwater)
3) treating the motors with light coat of varnish to help environmentally seal them a bit more
4) making some centering plugs instead of using the syringe bits
5) plugging one end of the e-chassis by swiveling some of the parts around, no need for potting the second hole
6) making an actual pressure relief plug that is o-ring sealed (tomorrow's project)

photo album of work so far here:

Note in the image, counter-rotating props FTW!


This is great! I'm excited to see the modifications! Do share!

Whoa, my comment just posted to two of your blogs...hmmm. Buggy. Fixing that.

getting set up at Neal's shop


Since the kitchen counter is not the best place to build an OpenROV, getting kit together to take to my friend Neal Chism's workshop for the build...


Ding Dong goes the doorbell! Ohmigosh its here! A box has arrived!!! headed over to the hardware store to pick up the necessary adhesives and such...

More photos!! And keep us posted throughout the build as well as the expedition/monitoring planning. A number of us are taking notes, so we can replicate it in our areas!

Oh, there will be photos AND video! Will be documenting it with excruciating detail I promise . My friend Neal Chism who as been interested in the OpenROV project for some time is clearing a bit of workspace for me in his garage as my initial plan of building on the kitchen table might not have been ideal from a coexisting with food standpoint :) This is great because he's helped me with several other projects and from a "doing it together" standpoint I couldn't have a better partner in crime from a tooling point of view :) (he's got a hotshop in his basement, an original Maker)

I'm excited to see the photos and videos, Laura!!

If you need a easy recording program to use from the OpenROV Cockpit, I can recommend TechSmith Snagit :)

Expedition Background

Up and down the Pacific Coast, starfish are dying by the tens of thousands and no one knows why. Special correspondent Katie Campbell reports from Seattle on how researchers and citizen scientists are investigating the spread of the mysterious and distressing syndrome.

Citizen Scientists in Seattle are exploring the benefits of doing video transect surveys with the help of OpenROV. By doing this, we believe that citizen scientists can be even more useful in helping the scientists studying the syndrome.

Currently the data reported is either via scuba divers or beach walkers. We envision an army of ROV's in the hands of curious citizen scientists no longer limited by the barriers of entry to scuba diving, no longer limited by the dividing line between land and sea. Now the citizen scientist can follow their interest beyond the intertidal range and collect relevant data beneath the surface.


This is so cool! The question we had last week: "how does someone contribute to this effort?"

Meaning, what are the steps for getting involved:

Step 1: Read an article (or watch a news segment) and think "Wow, that doesn't sound good. How can I contribute to getting this figured out?"

Step 2: Read the latest research (where to find this?)

Step 3: ?


I will make a follow-up post to build out this question/answer format! There are several exciting ways to get involved from something as simple as # an instagram picture of a beach where you've seen sea stars, all the way to a very comprehensive robust data driven protocol from Cornell and UC Santa Cruz. I believe we will be able to adapt the protocol adequately so as to make the data captured via OpenROV quite useful to the scientists, and will touch base with them to figure out best course of action.

this is righteous laura. I'm looking forward to seeing the video data!

I will bring my ROV and see if I can find some starfish! Do you know if it is found sick starfish in greater extent in deep or shallow water?

That is part of the question we hope to answer.

The researchers have data in the mid-level recreational diving depths. I have seen sick sea stars down in the 100-130 range, and will be doing some transects in the extended range down to 200.

The majority of the data we have underwater is coming from scuba divers so also only coming from 'regular dive sites', and from beach walkers in the intertidal zone.

Basically any data you can collect will be useful. If there are seastars, if they are healthy (or sick) or if there is an absences of sea stars. The best way to run the protocol is to find an object that you can visit again with regularity (something you recognize and easy to find) then run some transects over it and count the number of sea stars and note their size. (this can be done at home when watching the video later if you like) Then enter the data here:

or if you don't have time to do that or just want to go look around, at very least take a picture of the beach with your cell phone and at (or use manual entry) and note in the 'comments' what you observed on your dive.

Thank you!!

Good Luck Laura. I will be following your Expedition progress. Hopefully this wonderful new tool will help to shed some light on this very bad starfish wasting problem. Ron P.
