Wolf Eel Caught in Mid-Water Trawl Net Near Mendocino Coast

Our Department

We are faculty and students involved in oceanography and other marine sciences with access to a wide variety of research facilities and equipment, including on-campus analytical chemistry, geology and molecular biology laboratories, and computing and imaging facilities. We support collaborative research with partners at the nearby Monterey Bay Aquarium Research Institute, the Naval Postgraduate School, Stanford's Hopkins Marine Station, Moss Landing Laboratory, and others.

Ravelo: The gradual expansion of Northern Hemisphere glaciation about 3.6 million years ago followed a period of prolonged warmth. An analysis of ancient sea surface temperatures fuels the debate surrounding the roles of atmospheric carbon dioxide and global circulation in the cooling. The figures show documented changes in global ice volume as reconstructed from a variety of researchers. [From: AC Ravelo. 2010. Palaeoclimate: Warmth and glaciation. Nature Geoscience 3: 672–674]

Zehr: UCYN-A cyanobacteria is an unusual marine microorganism with a remarkably reduced set of genes. It is uniquely uniquely suited for nitrogen fixation, as it is lacking in the genes for a key component of the photosynthesis, the TCA cycle, and the Calvin cycle. Samples collected from the open ocean indicate that this microbe is periodically abundant in tropical and subtropical waters throughout the world. This organism may be an important part of the overall nitrogen budget of the oceans.

Silver: Toxin-producing Pseudo-nitzschia, once thought to be limited to coastal waters, are also common in the open ocean where the addition of iron from natural or artificial sources can stimulate rapid growth of the harmful algae.
