Algae, ciliates, and other microorganisms get eaten by bigger creatures, like the zooplankton that Woods Hole Oceanographic Institution biologist Phil Alatalo caught in his net last night. Here, he's rinsing his catch down to the bottom. The algae bloom means his tiny crustaceans have a lot to choose from today, as they sit for 24 hours in bottles, eating the food in the water. And that means he and his colleagues will learn more about what the animals like to eat. "When we conduct our grazing experiments with these animals, we know in the water there's a tremendous potpourri of organisms," he says. "We'll see if they choose these juicy little ciliates."

Algae, ciliates, and other microorganisms get eaten by bigger creatures, like the zooplankton that WHOI biologist Phil Alatalo caught in his net. As part of the zooplankton team aboard the research vessel, Alatalo was studying how the changing sea ice affects the Artic food web. Here, he's rinsing the catch down to the bottom. ?When we conduct our grazing experiments with these animals, we know in the water there's a tremendous potpourri of organisms,? he says. ?We?ll see if they choose these juicy little ciliates.?
