Virtual Field Trip to the Bottom of the Ocean

We're heading to the bottom of the ocean to the one-of-a-kind Aquarius Reef Base, the world’s only undersea research laboratory for a series of 4 Google Hangouts to tour the base and learn about the impact of sharks on coral reef ecosystems. We'll be connecting with 5 teachers who are taking part in the Teacher Under the Sea Program. These teachers participated in Aquarius's 'Ecology of Fear Mission: Impact of Sharks of on Coral Reefs" last November. On Friday, March 25th they will be going back to Aquarius to share their experience as Teachers Under the Sea by connecting with students around the world and inspiring them by the idea of living underwater. Background In most marine environments, sharks are the top predator. In the last few decades, populations of large shark species have declined by 70-90 percent. The loss of these predators not only threatens the survival of one of the world’s oldest lineages of fish, but has also left scientists scrambling to understand the role sharks play in maintaining healthy ocean ecosystems. Coral reefs face potential collapse in the coming century. Many reefs around the world are transitioning from vibrant coral communities to seaweed-covered rocks. Large predators such as sharks may help prevent this decline.  The Science Last November, using low frequency sound to attract sharks, scientists used a combination of HD remote video, controlled from within the Aquarius habitat and multi-beam imaging sonar to quantify how different species of fishes’ behavior changes in the presence and absence of sharks. This study, part of the Global FinPrint project, will be the first to utilize imaging sonar and baited remote underwater video (BRUV) to provide exact, quantifiable data on reef fish behavior in the presence and absence of sharks.  Aquarius Deployed 60 feet beneath the surface in the Florida Keys National Marine Sanctuary, Aquarius is a globally significant asset that provides unparalleled means to study the ocean, test and develop state-of-the-art undersea technology, train specialized divers and astronauts, and engage the world's imagination. At Aquarius, scientists are at the cutting edge of research on coral reefs, ocean acidification, climate change, fisheries and the overall health of the oceans. These hangouts will be taking place on a holiday for many schools, however we are encouraging students to watch live from the event page or YouTube at home and share the experience with their families. We'd also welcome any day camp or museum groups that would like to join in for a camera spot.
