We are so proud today to present you one of the final steps of our Beaufighter mission. Antoine, one of the team members, is a very good sailor, but he is also a fantastic drawer. For three months, he has been working on an alternate way to explain what we are doing . The result is incredible. We have self-published a 65 pages of cartoon that present the Octopus Foundation, who we are and the work we are trying to accomplish for the public. Unfortunately folks, it is right now still in French. For English, we would need a publisher. Anyone interested around you ? To start with, here are a couple of visuals, so you have an idea of how incredible Antoine's drawings are. Thanks to everyone.
Here it is. Finally ! The 3D printed model just finished to be painted. Thanks to this model, we can now show everyone underwater areas of interest, either biologically or archeologically. We are now ready to open more windows on the seas and oceans.
Here are the final products that we can display for scientists and the public :
1) The 3D digital model
2) The orthophotoplan
3) The 3D printed model
Thank you so much to all our supporters and everyone that has and will help us achieve our endeavor ! Let's start the adventure !!
Here is the final result of our May 2015 mission in Fiskardo (Greece). The laser 3D printed of our working zone (80m * 40m at 17 meters deep) by Sculpteo. Thanks to this model the OCEAN71 Magazine team proves that the ocean floor is not anymore accessible just to the major players of the industry but also to the PUBLIC.
I take this opportunity to announce you our latest project : The 2015 Fiskardo mission was a pilot, in order to see if we could achieve with simple means a way to show the ocean floor and all the biological and cultural treasures.
Today, I am very proud to announce the launch of the "OCTOPUS Foundation" that will aim to make things a lot easier to show everyone of you these underwater marvels and inform you a lot better ! A lot is to come in the next couple of months.
Note : Thanks to all our partners for this pilot project and Novalta for the 3D modeling solution.
Here is a nice Bonus post. After having completed a planned flight over our working zone with our Phantom 2, equipped with the Datalink chip, we managed to create an aerial plan of the zone. In it, we implemented the underwater plan, thanks to buoys' positions on the surface. We call this image : the window on the sea. Here it is finally, our plan for the future. To make this unknown world available to everyone !
Hey OpenExplorer community,
The OCEAN71 Magazine team has been working in the past weeks on processing all the data collected on the Fiskardo underwater spot. We are proud to say that the result looks great. We managed all together to make a full 3D model of the two squares we worked on for almost 10 days.
Here it is. Just play with it !
Mission Day 11 – Ultimate Bonus
For the fun and to crown one successful mission, the Novalta Tech team has proceeded to a last OpenROV test enhancing its capabilities with the addition of an action camera. The last minute call for an unprepared OpenROV mission ended up in a quick survey of small wreck lying on the seabed in a nearby bay. A small door open to a vast world of opportunities…
Mission Day 11
The Expedition team is about to split in two parts for the end of the mission. One part of the team will sail the boat back to Lefkas and will proceed with some structured scanning of the working zone on its way to Eclipse’s summer port. The other half of the group will do some last OpenROV testing before packing. An obviously good reason to do a group photo celebrating the success of the Fiskardo – Greece 2015 mission.
Mission Day 10 – Bonus
An outstanding result proving the incredible innovative capabilities of the Novalta Tech team, this 3D model of working zone 2 offers our followers the opportunity to participate into our underwater investigations eventually allowing them - and you - to “dive” with us on the Beaufighter exploration site. (By the way this site is 400m2).
Mission Day 10 – Dives 10 & 11
While the dive team is proceeding with some new exploratory dives outside the working zone the Novalta Tech team follows up on its post-production work processing this amazing orthophoto mapping of one of the working zones here presented at a downscaled resolution of 5 cm/px.
Mission Day 9 – Bonus 2
The tech team from Novalta has processed the batch from today’s acquisition dive and we’re all happy to share with you the amazing results showcasing all the efforts spent in digital mapping of the working zone 2 and its many artifacts. Here is the first 3D model. Enjoy !!!
Mission Day 9 – Dive 9
In the afternoon, the dive team proceeds with the examination and documentation of new artifacts from the wrecked Beaufighter bomber methodically taking a batch of photos of each of the new spotted remains. Eventually, one piece looking like some kind of an exhaust pipe - or at least part of it – would reveal a serial number that may ultimately confirm the identification of the plane.
Mission Day 9 – Dive 8
Due to extreme wind conditions the Mission Day 8 has been dedicated to home work in order to improve some electronic issues on various tools including the OpenROV, the cameras... Today the dive team is back underwater to perform another set of data acquisition by scooter. Both photo and video modes are used on each ride while surveying working zone 2.
Mission Day 8
Here is an example of how new tech can be used to help journalists tell stories : using aerial footage taken by our drone and applying a 3D reconstruction of the Bristol Beaufighter, we are able to show you the final 30 seconds of the fighter from the moment it was shot by the German canon to the final crash in the water where we are currently studying the remains.
Mission Day 7 – Afternoon
The tech team from Novalta headed by Technology officers Charles and Fabien who have defined much of the expedition’s acquisition procedures spends most of the after dive stages processing the data collected underwater, putting much effort into digital underwater mapping of the working zones. Today’s task has been dedicated to post production handling of the artifacts’ photographs and to digital processing of their 3D representations.
Mission Day 7 – Dive 7
The underwater team is now focusing on the artifacts lying on the seabed of the working zone. Each remains of the RAF NE595 Bristol Beaufighter bomber plane is now methodically documented in order to comply with identification and digital graphic computing requirements. At the end the final artifact list will help implementing the plane’s tragic ending and its related account.
Mission Day 6 – Afternoon
Getting higher… The surface team with drone master Fabien and Expedition leader Julien have walked across the dense coastal vegetation to touch base near the working zone’s shore. The multirotor drones soon roar in the sky above the dive site undertaking aerial mapping surveys of the working zone while the dive team starts underwater acquisition of first batches of photogrammetric data.
Mission Day 6
“Getting high…” This morning the multirotor drones are set free for some fresh air testing. All systems proving clear and operational a first drone is sent up in the blue sky for an opening flight over the Fiskardo bay and harbor with aerial shooting of the Fiskardo Divers boat leaving for the morning dive. Our underwater photographer Phil has joined the boat to do some general surface and underwater filming.
Mission Day 5 – Dive 5
On the afternoon dive, team 1 goes on a search for plane debris outside the working zone but towards the deep waters and the original crash site. At the same time team 2 proceeds with another round of search along the coast but using underwater metal detectors this time. In the meantime a new investigation tool is deployed by the surface team, a little autonomous yellow submarine named “Neptune”. Conclusive navigation tests are successfully conducted up to 12 m deep.
Mission Day 5 – Dive 4
Last night’s debriefing has exposed a need for additional photogrammetry calibration. Team 1 undertakes the required underwater adjustments then proceeds with the testing of the scooter getting used to operate it with respect with the compulsory depth + azimuth coordinates. Team 2 spends the dive searching for new plane debris potentially scattered outside the working zone (shallow waters along the coast). In the meantime the surface team is training and practicing on OpenROV navigation.
Mission Day 4 – Dive 3
Back on the Beaufighter site the underwater team finalizes marking of the working zone 2 (the deepest one) then undertakes marking of the collateral working zone 1 (upper zone towards the coast). The virtual grid is set on the two zones to allow suitable photogrammetry survey by manned underwater camera then with the help of the underwater scooter. The global working zone is now ready for full precise scanning and systematic mapping.
Mission Day 3
OpenRov 2.7 testing. Upgraded system is digitally finalized before getting used to the settings and cruise controls. Electronics, power and motor are checked. Balance and buoyancy controls are also tested making sure all systems are clear and watertight. Remote control testing finally helps the crew getting used to the handling of the OpenROV underwater.
Mission Day 2 – Dive 2
Clearing sky and downing winds open a window in the afternoon allowing the team to be back in action on the diving spot. A solid briefing allows perfect timing and impeccable underwater organization to refine sizing of the working zone’s quadra and marking its surface boundaries with yellow floats. A new set of measurements is completed while the surface team works on testing the OpenROV 2.7. The sun eventually comes from behind the clouds to crown the fruitful afternoon.
Mission Day 2
Action is down for the morning because of blowing wind and chopped seas: time for an OpenROV workshop. Gathered around our Drone & ROV master Fabien, the team appreciates the wonders and refinements of putting together the various parts of the OpenROV 2.7. Again, it’s all about electronics and O-rings. Once the ROV is fully set the computer links and video feed are tested. All systems clear. Ready to go diving for balance and thrusting tests.
Mission Day 1 - Dive 1
The dive team is on the spot. Seabed and surface marking of the working zone has been initiated along with initial rough measurements of the designated quadra. Fist video survey tests have also been realized to allow testing of the digital mapping program. Good diving conditions with flat sea and excellent visibility on spot. Team working needs some fine tuning but globally operates well. More on this later.
Mission Day 1
The Ocean71 team has regrouped in Fiskardo and has established its HQ at the Fiskardo-Divers Eco Dive Resort. Task one: opening travel cases, making sure all the equipment hasn’t suffered too much from air or sea transportation then putting together all the forth required equipment which basically consist in battling with electronics and O-rings… (not mentioning hooking on the good Wi-Fi to allow connection with the world and our potential followers!). In the meantime the dive team is getting organized for the first dive of the day that will be mostly dedicated to being familiarized with the working zone and having it demarcated. More on this later.
After many missions along the coast of the north-western Mediterranean sea in the past two years, OCEAN71 expeditions return to Fiskardo, in the Ionian Islands, Greece, where the team has initiated ground contacts and preliminary investigations on the remains of an English Beaufighter bomber plane that was shot down during WWII and that sank after an emergency landing on water. The purpose of this 2015 expedition is to push further the underwater investigations of the wreck and complete a comprehensive survey of the whole event. In parallel the OCEAN71 team will set up an ethological survey of the endangered Mediterranean monk seal using various techniques to document its behavior and notably its traveling habits in and out the various caves where it has been spoted by local divers and volunteers from Fiskardo Divers Eco Dive Resort.
