Predicted Change to the Southern Ocean Silicate Front

The Southern Ocean Silicate Front (SF) is an important boundary separating waters that are silicate-rich and waters that are silicate-poor. The position of the SF determines where microorganisms like diatoms (that need silicate to form their shells) can grow. A new study predicts a poleward shift in the Southern Ocean Silicate Front by the end […]

Marine Snow & Muddy Megacoring on the Southern Ocean

Check out this guest post by Marlo Garnsworthy to read about an exciting voyage to the Southern Ocean…Marlo took part in a several week research cruise to learn about climate change using sediment samples from the region…read on to learn about the experience and see Marlo’s great pictures!

Marine diatoms eat climate change’s dust

Multiple, interacting factors from climate change make it difficult for scientists to predict how marine life will respond to climate change. Read on to find out how researchers studied the effects of dust deposition, ocean warming, and increased carbon dioxide concentrations on a common marine diatom. Katherine BarrettKate is a 2nd year PhD student in […]
