On Monday, February 6, 2017, around 1:30 a.m. CST, a sonic boom shook residents of the Midwest as a bright green fireball streaked through the night sky. The sound was that of a meteor, nearly the size of a minivan, entering our atmosphere. After its fall to Earth, radar spotted the end of its journey over Lake Michigan, approximately 10 miles off the coast of Sheboygan, Wisconsin. Teen explorers from Chicago, led by scientists from the Adler Planetarium's Far Horizons program, The Shedd Aquarium, and The Field Museum, team up to take on this Underwater ROV Meteorite Hunt. Interested explorers wanted!

Lurking in the mists and fog, just thirty miles from San Francisco, lie the Farallon Islands. Called the Devil's Teeth by wary mariners and the islands of the Dead by Native Americans, these jagged spires and barren rocks are a Fish and Wildlife Refuge, and nested within the Greater Farallones National Marine Sanctuary. These enigmatic islands are critical habitat for 350,000 nesting seabirds, 6 species of seals and sea lions, amazing fish including great white sharks! The Farallon Islands are also part of our California Marine Protected Area network. Lesser known are our coastal Marin Protected Areas in the Golden Gate region including Point Reyes, Duxbury Reef, Drakes Estero and several special closures. The MPA Watch program is part of the collaborative effort to monitor MPAs for human activity and habitat, and educate the public on marine protection. We are using the Trident to examine habitat and species offshore, but also nearshore in eelgrass beds in the San Francisco Bay and Drakes Estero. This program provides monitoring opportunities, education and adventure. Located so close to our coastline, the island wildlife and habitat have been impacted from overfishing, sealing and pollution historically and remain at risk from oil spills and shipping. As part of the ecosystem managed of 124 MPAs, our marine wildlife and habitat have an opportunity to recover. Solutions include event protection as part of our State network of marine protected areas and applying citizen science observations collecting data on wildlife and human behavior using app technology. With the Trident ROV we are recording observations of benthic and nektonic wildlife, and human interactions within the MPAs. Every fall Shark Stewards leads public education expeditions to the islands discussing history, natural history and ocean solutions and applies citizen science to marine conservation. Now using the Trident drones, we are collecting scientific observations for our California Marine Protected Area network that can be used by fisheries biologists and managers. Using Whale Alert and iNaturalist apps we also record whale and shark observations inside the Sanctuary.

I started walking from the northest point in Iceland, the lighthouse of Hranhafnartangi, right below the artic circle. I walked 620Km through the highlands, climbed Askja, crossing the largest desert in Europe the Odadharaun drinking 1Lt of water per day, touching the biggest glacier in Europe the Vatnajokull (retiring dramatically), till ending on the southest point, the lighthouse of Dyrholaey. I carried all the food and the camera gear, almost 40Kg backpack, for a total elevation of 10500 meters, during the worst summer of the last 100 years, at least what the newspapers said, fighting with rain and wind (sometimes till 130Km/h) and chasing the perfect picture.

Decades of successful management in Komodo National Park secured a good portion of the species’ small but stable population, along with the bulk of its current habitat. Today, 2,500 dragons – most of its wild population – live inside the park, with smaller numbers inhabiting a handful of surrounding islands.

I launched the award-winning Climate Listening Project in 2014 and traveled across the United States and around the world to explore and film the connections that are important to each of us: family, faith, business, environment, community; weaving together the latest science with inspiring stories from around the globe. I am re-launching the Climate Listening Project with a new vision, not only focusing on our changing climate, but how we are changing as individuals, listening to our own realities, overcoming our fears and stereotypes, healing ourselves, and allowing ourselves to be our whole selves. I think real change is not just about acknowledging and adapting to our changing weather - it is about changing our political climate, social climate, inclusion climate, and economic climate. We all have unique and important stories, contributions, experiences, and perspectives as we listen, learn, change, and grow. The Climate Listening Project shares these stories of transformation. http://ClimateListeningProject.org

Glacier Bay National Park, Gustavus, Alaska 99826, United States, Jul 31 to Aug 4 1916
The Lost Study of Glacier Bay
Glacier Bay, Alaska, is a wild place. It's also critical to science. The longest running study in the world focused on how ecosystems grow and change as glaciers retreat and climate warms was located in the back of the bay. Started in 1916 by one of the countries leading ecologists, the study ran for over 75 years - but then was lost, as the original researchers died. In 2016, the plots were rediscovered through a combination of old sketch maps, compasses, notes, faded photographs, and wilderness exploring. It's a story reminiscent of John Muir crossed with Indiana Jones, where X marked the spot and old buried spikes were pursued like a needle in a Glacier Bay sized haystack. The expedition was successful, and the longest running study is all set for the next 100 years of monitoring.

A ROV called Trident For our expedition, one of the great tools that we will be using is the Trident Remotely Operated Vehicule (ROV) from OpenROV. This is basically the underwater version of a drone. It "flies" through the water and thanks to its integrated camera, let you see and explore the ocean just like if you were diving. Unlike many ROVs, it is small, very portable and can be controlled from shore or from any type of boats (motor boats, kayaks, etc.). This amazing little instrument will be key for many aspects of our expedition. Searching for good deployment sites. Once we have selected the general location of our study sites, we need to find the perfect spot to deploy our hydrophone and camera array. It needs to be relatively flat for the structure to be stable and close to fish aggregations, so we can capture their sounds. The Trident will be used before the deployment to identify good locations for the array. Retrieving the hydrophone array. Deploying the hydrophone array on the ocean floor is easy. We just lower it down from the boat with a line. Once the array is on the bottom, we let go one end of the line and pull on the other end to get it back. To retrieve the array, this is more tricky. We need to find a way to attach the line back to the array. We can't leave a surface float on the array like crab or lobster traps because it would make too much noise that would contaminate our acoustic recordings. So, instead we will use the Trident to hook the line back to the array. Just like the video below. Then, we can pull the array back at the surface from the boat using that line. This retrieval technique is efficient, requires only 2 persons and will allow us to deploy in many places around the BC coast. Cataloging fish sounds. Many fishes like to hide and hang out in rocks and boulders. Unfortunately, due to its size and shape, our hydrophone and camera array can only be deployed in areas where the bottom is relatively flat. So, we will design a small array of 2 or 3 hydrophones that we will attach to the Trident. These hydrophones combined with the camera from the Trident will allow us to catalog fish sounds in much more complex habitats than with the fixed array. This idea is actually not new. Rodney and Francis have already tried to had hydrophones to ROVs almost 10 years ago (see their paper here). But what they found at the time is that regular ROVs are very noisy and make the recording of fish sounds very challenging. With its much smaller and streamlined design, we are very confident that the Trident won't have that problem. I am so excited to start playing with this really neat ROV!
In the understory of Mt. Gorongosa rainforest lives a fly Glaurocara sp.n., a parasitoid of False shieldback katydids (Acilacris incisus). As all parasitoids do, it eventually kills its host. The katydid, in turn, feeds on the plant Dracaena fragrans, often causing damage to its reproductive structures. The plant serves as a microhabitat to a number of species of invertebrates and frogs. Thus, by constraining the population growth of the herbivorous katydid the fly acts as a defender of the plant and all species that depend on it. The Gorongosa Map of Life project connects the dots.
Giant African snail (Achatina immaculata) is one four species of the genus Achatina found in Gorongosa. These massive mollusks are some of the world’s largest terrestrial snails, reaching the shell length of over 15 cm. Their reproductive behavior involves hermaphroditic mutual insemination (each individual has both male and female reproductive organs), albeit younger, smaller snails can only play the role of males – they can inseminate other snails but cannot produce eggs until they reach a larger size. Large, fully mature individuals both impregnate and get pregnant at the same time. Strange stuff.
