ACTIVITIES

Ecosystem Research – Recent research has focused on nutrient cycling in the Bering Sea, Gulf of Alaska, and Aleutian Passes using underway, moored and hydrographic data.  I have received grants for maintaining a moored nitrate meter along the 70m isobath on the Bering Sea shelf, for examining the distribution, utilization, and recycling of nutrients on the Bering Sea shelf during spring and fall cruises in 2008-2011, and for developing nutrient budgets (including seasonal, cross-shelf, and vertical) in the northern Gulf of Alaska by integrating hydrographic and moored data sets with models.

Underway Mapping – I have deployed chemical and optical nitrate meters on several ships of opportunity including the Alaska Ferry Tustumena which frequently crosses the Alaska Coastal Current.

In-Situ Chemistry – I have deployed about 30 nitrate meters in the Gulf of Alaska, in the Aleutian Passes and in the Bering Sea from grants with GLOBEC, Stellar Sea Lion, NOAA and NSF.  Additional engineering was required for the instrument to reliably operate in deeper water, and consequently we were able to resolve the deep nitrate – salinity relationship in the Gulf of Alaska and Aleutian Passes (Mordy et al., 2005).  Deployments of optical nitrate meters in the Chukchi Sea begin in fall 2010.  

Climate Research – I have been involved in the collection and final quality control of dissolved inorganic nutrient data for the International World Ocean Circulation Experiment (WOCE; Key et al., 2004), and represent one of three groups involved in the collection of nutrient data for the U.S. CLIVAR hydrographic program (along with Scripps Institute of Oceanography and the Atlantic Oceanographic and Meteorological Laboratory).  Since 1994, I have been the recipient of about 15 grants for the collection of nutrient data on WOCE, CLIVAR, and Coastal Carbon Surveys.
