What if your physical characteristics (hair color, height, or eye color) were determined by your bacterial microbiome? It might seem far fetched for humans, but for some marine species, this is a fact of life. We recently had a foreign emissary visit the lab, one Catherine Burke from the University of Technology in Sydney, Australia. . . . → Read More: Algal blobs take shape, thanks to bacteria
If you were at the beach in San Diego this weekend, especially off La Jolla Shores, you might have seen streaks of green sea foam. Here’s a stunning photo of the foam off Scripps pier, taken by Eddie Kisfaludy from a small plane 1,500 feet above the ocean. Streaks of green foam (Tetraselmis spp.) off . . . → Read More: What is the green sea foam off La Jolla Shores (San Diego)?
Battle lines are drawn and chemical warfare commences between alga (left) and coral (right).

He will be posting regular updates on the expedition exclusively for Deep Sea News . . . → Read More: Dispatches from Antarctica – Sampling the Inverted Benthos
BERLIN (AFP) — Indian and German scientists have said that a controversial experiment has “dampened hopes” that dumping hundreds of tonnes of dissolved iron in the Southern Ocean can lessen global warming. The experiment involved “fertilising” a 300-square-kilometre (115-sqare-mile) area of ocean inside the core of an eddy — an immense rotating column of water . . . → Read More: Iron Fertilization Will Not Help Global Warming
Some of the species in the genus Pseudo-nitzschia are nasty little diatoms. They produce domoic acid, a neurotoxin typically to blame for all sorts of marine vertebrate deaths. Alfred Hitcocks’s 1963 film “The Birds” dramatizes a bird attack incident blamed on domoic acid. Human consumption of shellfish that has filtered Pseudo-nitzschia leads to amnesic shellfish . . . → Read More: Nerve Toxins In The Deep
