Neil Lumsden was out surfing when out of nowhere the recent earthquake struck the deep sea off of Samoa. We had no warning, being out in the water outside of the reef pass we didn’t feel the earthquake happen, and everyone was caught completely off guard. All of a sudden, while sitting at the usual . . . → Read More: Samoan Tsunami Survivor

The paleoceanography of the deep-sea is an account of intense fluctuations in temperature, oxygen, and circulation. In the past . . . → Read More: The Origins of Deep-Sea Fauna
