Analyzes marine communities associated with the porous boundaries of the ocean, from sedimented seafloor and hydrothermal vents to sea ice (inverted benthos); emphasizing nutrition to these communities, including sinking organic aggregates, themselves porous habitats, and the role of symbiosis. Prerequisite: permission of instructor. Offered: W, even years.
The official UW description of this course does not reflect its recent evolution, in which it has expanded beyond the original focus on soft substrata (sediments). We now also consider the biology of other porous boundaries of the ocean -- sea ice cover, erupting seafloor structures (hydrothermal vents), and the subseafloor biosphere. The overall goal of the course is thus to provide and explore (in assignments based on student-selected study questions) fundamental information about life in the ocean at its various boundaries, complementing the other graduate-level courses in biological oceanography which all focus on life in the pelagic realm. The link between these courses (also addressed in Marine Benthic Ecology) is the descent of organic aggregates through the water column, not only providing nutrition to organisms that live at depth in the ocean but also serving as small-scale habitats themselves. In Winter 2014, this course will be co-taught with new faculty member Alex Gagnon whose areas of interest include biological responses to ocean acidification and life in the deep sea. Laurenz Thomsen from the Jacobs University in Bremen, Germany, will also contribute to the course, including video coverage of his benthic crawler currently operating in NE Pacific waters. Note that this course qualifies as an out-of-option course for non-biology students in Oceanography. It will meet Mon and Wed 11:00-12:20 in OTB 205.
