In the open ocean around the Bahamas, pods of wild Spotted Dolphins frolic in the sunshine. Sometimes, they get bored and approach boats. In this educational video, Jonathan joins dolphin expert Wayne Scott Smith to learn how dolphins interact with each other. Jonathan learns how to play the Bandana Game, a game of -keep away- that the dolphins invented and like to play with Scott. Please see the accompanying study guide for educational objectives and discussion points.

In this video, Jonathan travels to Canada in search of the Greenland shark, a huge, lethargic shark that lives in arctic waters. It takes days of effort, but finally, in dark, cold, murky water, Jonathan finally meets this elusive animal, and it's nothing like he expected. Please see the accompanying study guide for educational objectives and discussion points.

In the north Atlantic, the American Lobster is the undisputed king of crustaceans. ItŰŞs also a tremendously important commercial catch. While all the other fisheries are collapsing, why are lobsters resisting the trend? In this video, Jonathan goes out with a Maine lobsterman to learn why, and he dives down below to find the biggest lobsters he has ever seen. This segment won a New England Emmy Award! Please see the accompanying study guide for educational objectives and discussion points.

"Phytoplankton communities play major roles in global biogeochemical cycles and marine food webs. However, the complex phytoplankton communities in polar vs. non-polar oceans haven’t been well characterized. To address this gap, researchers recently profiled the metagenome-assembled genomes (MAGs) of eukaryotic microbes and associated prokaryotes from the chlorophyll A maximum layer at 11 sites in the Arctic and Atlantic Oceans. Within each ocean, adjacent sampling sites had 51–88% of their MAGs in common, but the Arctic and Atlantic MAGs were clearly differentiated. Most species associations were between Prasinophytes and Proteobacteria. In addition, eukaryotic MAGs were more diverse in the Arctic, while prokaryotic MAGs were more diverse in the Atlantic. For both prokaryotes and eukaryotes, 70% of the detected protein families were shared between Arctic and Atlantic MAGs. but eukaryotic MAGs had more Arctic-only protein families, whereas prokaryotic MAGs had more Atlantic-only protein families..."

"Oil spills have devastating effects on the environment, and thousands, of varying size, occur each year. Spilled oil can be removed from the environment in numerous ways, such as with the use of dispersants to break up oil slicks on the water surface. But while oil spills themselves pose well-known threats to marine life, the methods used for oil cleanup can also have unintended consequences. To examine these effects, researchers recently investigated how treatment of oil with dispersants produced synthetically (Finasol) and by bacteria (rhamnolipid) impact microbial communities and their ability to break down oil from the subarctic Atlantic Ocean. They found that cold-loving bacteria initially dominated the bacterial communities when both dispersants were used, but some key species of bacteria that specialize in breaking down aromatic hydrocarbons, which are the major and most toxic components of crude oil, became abundant over time in only the presence of rhamnolipid..."

At first glance, starfish, more properly called sea stars, arenŰŞt doing much of anything. In this video, JonathanŰŞs investigations reveal a slow-motion predator that hunts and attacks its prey. Traveling the world, Jonathan investigates sea stars from the tropics to the Antarctic and uses time-lapse photography to reveal an amazing complexity to the world of the sea star. Please see the accompanying study guide for educational objectives and discussion points.

Sharks and many other large ocean animals have sucker-equipped fish called remoras sticking to them. What are the remoras doing? Do they harm the sharks? In this video, Jonathan goes on a mission to investigate remoras and their role in the food web. He even sticks one on himself. Please see the accompanying study guide for educational objectives and discussion points.

In this video, filmed thirty miles off the coast of North Carolina, there is a shipwreck on the bottom, 130 feet down. Swarming around the wreck are dozens of Sand Tiger sharks. They look menacing, but they seem to be very docile. What are they all doing there, in one spot? That's what Jonathan wants to find out. Using a variety of filming techniques, Jonathan attempts to discover the secrets of the Sand Tiger shark gatherings at the wrecks, and does the first ever night dive with these shark..talk about scary! Please see the accompanying study guide for educational objectives and discussion points.
Millions of fish eggs from the Caribbean get stuck in the gulf …
Millions of fish eggs from the Caribbean get stuck in the gulf stream every year and drift thousands of miles north where they hatch. Unfortunately, when winter comes, the baby fish will die. In this video, Jonathan joins the New England Aquarium Dive Club on a tropical fish rescue in Rhode Island where they catch some of these fish in the fall before water temperatures plummet. The fish go to the New England AquariumŰŞs exhibits. Please see the accompanying study guide for educational objectives and discussion points.
