An entire series is now on Science 360: The Knowledge Network. YouTube videos are filtered from some classrooms. Since Science 360 is sponsored by the National Science Foundation, their videos have passed a high academic standard and are not filtered.
Courtesy C-MOREThe Center for Microbial Oceanography (C-MORE), headquartered at the University of Hawai`i, conducted the BiG RAPA oceanographic expedition. The C-MORE scientists sailed from Chile to Easter Island, making discoveries about micro-life in one of the least explored areas of the world's ocean.

Oceanographers on C-MORE’s BiG RAPA oceanographic expedition are finding bacteria the size of one-one-millionth of a meter in the oligotrophic (low nutrient), open-ocean of the Southeast Pacific, far from the productive waters off the coast of Chile. But that’s not all; some scientists are looking for the even smaller marine viruses in gallons of filtered seawater. Meet some of these micro-microbes in these video reports:

Yes indeed, microbial oceanographers are taking home quite a collection from the South Pacific Ocean. In less than a week the good ship RV Melville will arrive at Rapa Nui (Easter Island), and scientists will step onto land for the first time in almost a month. They and their oceanographic samples will return to C-MORE laboratories around the U.S. The oceanographers are also returning with new hypotheses buzzing around in their heads. Now it’s time for them to take the next step in the Scientific Method: data analysis!
Courtesy C-MOREMicrobial oceanographers on C-MORE’s BiG RAPA oceanographic expedition have transited from the coast of Chile to 1000 miles offshore. No longer are the scientists in rich, productive coastal water. Now the ship is in clear-blue, open-ocean seas. Learn why Dr. Angel White from Oregon State University says the change is like going from the Amazon to the Sahara Desert in this video of BiG RAPA’s discoveries.
Courtesy C-MOREYou’ve probably seen all sorts of colors in the ocean: deep-blue, turquoise-blue, light-green, brown, even gray on a gray day. But red? Microbial oceanographers on C-MORE's (Center for Microbial Oceanography: Research and Education) BiG RAPA oceanographic expedition have seen a red ocean off the coast of Chile! Huh?! Learn what a plankton net is, and then see what caused the strange red color.
Courtesy C-MOREDr. Dan Repeta from the Woods Hole Oceanographic Institution (WHOI) is C-MORE’s Chief Scientist on the BiG RAPA expedition, which is conducting research off the coast of Chile. Dr. Repeta and his team of scientists are sampling the underwater microbial environment using a variety of instruments, including a water collector called a CTD (see educational resource below). Two interesting results have turned up in the CTD data:
