Oh the dark deep sea is frightful, But the food not so delightful, But since we’ve got no place to go, Let It Marine Snow! Let It Marine Snow! Let It Marine Snow! The deep-sea floor is a patch mosaic of habitats In the late 1960’s, two marine biologists, Howard Sanders and Robert Hessler, . . . → Read More: Let It Snow, Let It Snow, Let It Snow

Carbon, diatom, frustules, phytoplankton, Scientist In Residence Dear Diatoms, You are pretty, and I like you. Haeckel liked you too, so did Gaudi. Obviously, they appreciated the little things in life. While you still make appearances now and again in modern life, let’s face it: being microscopic and aquatic, recognition is an up-current battle, and you can’t swim. Perhaps obscurity suits you? . . . → Read More: Scientist In Residence: Danny Richter on the To Humble Diatom

Majority consensus makes me shudder. I just like rooting for underdogs*. Those undersea ridges at the boundaries of tectonic plates, spewing molten magma to form new crust are o’ so popular these days. Spreading plate boundaries…meh. What I do like is new research basically stating, and I am paraphrasing here, that spreading . . . → Read More: I Like Sills But Not A Fan Of The Popular Or My Friend’s Ex

For a while it was assumed that the anemones mainly persisted by utilizing carbon translocated from its symbionts, called autotrophy, but they can may supplement this by heterotrophic feeding on plankton. A study by Bachar and colleagues followed . . . → Read More: Determining the Fate of Carbon in a Mixotrophic Anemone

The report comes from a talk at The Ocean Science meeting in Portland last week discussing some calculations presented by Dr. Andrew Pershing on how whaling is putting “locked up” carbon back into the atmosphere. “Whales, like any . . . → Read More: Won’t They Think of the Poor Bone-Eating Worms?
