Before you watch the videos below I urge you to head over to Highly Allochthonous. Chris Rowan has two excellent posts explaining the geology behind the earthquake, tsunami and aftershocks of the Sendai earthquake. I also liked the Georneys and AGU Blogosphere posts (hat tip to Chris for pointing me in their direction). You also . . . → Read More: Tsunami Video Roundup

That was made possible by the wonderful dive master, Alfi Ramsay, and Dive.IS for logistical support. He made the dives extremely smooth and left me with a great deal of knowledge including his four rules of scuba diving. Look good If you make . . . → Read More: Diving Iceland

Heightened biodiversity may make an ecosystem more stabile and robust. One of the reasons for this is that high biodiversity may create redundant species, i.e. species that serve a similar ecological role in the ecosystem. A loss of . . . → Read More: Tide Pool: Cephalopods, Ash, and Sulphur Are to Blame

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.

My labmate came across this compelling illustration today searching Google Images for seafloor spreading illustrations. Click on image for the original.

Large deposits of methane hydrates, i.e. methane ice, occur naturally in the seafloor sediments of the Arctic continental shelf between 300-600 meters. This is dominate reservoir for methane due to the large area and extremely low temperatures. The continued and predicted warming of . . . → Read More: Ocean Warming Melts Methane Hydrates Which Screws Us All
