Project Team: Jeremy Mathis (co-PI, University of Alaska, Fairbanks), Kathleen Stafford (co-PI, University of Washington), William Williams (collaborator, IOS, Sidney, BC)

Objective(s): To characterize the western Arctic Boundary current (which flows at the edge of the shelf), in order to understand its role in dictating shelf-basin exchange of water and materials and how it impacts the ecosystem of the region, including the occurrence of marine mammals.

Project Description: The main objective is to characterize the western Arctic Boundary current (which flows at the edge of the shelf), in order to understand its role in dictating shelf-basin exchange of water and materials and how it impacts the ecosystem of the region, including the occurrence of marine mammals.

This project is a collaboration between US and Canadian scientists. The research team are using a combination of year-round subsurface moorings in the boundary current (deployed in US and Canadian waters), and seasonal (summertime/autumn) shipboard measurements, including measurements in Canadian waters. The team will be lowering our instrument package (standard CTD/Rosette) at each station. The package carries an array of electronic sensors to measure water properties (primarily temperature, salinity and depth) and 10 litre bottles that are closed at specified depths to take water samples. No biological or fish sampling will be conducted. The research team will not be using any nets or sediment grabs.

The research team plans on an outreach visit to the local communities explaining the results.

Data reports will be available and scientific papers will be published based on the data. The scientific data are available to the public at the project website http://aon.whoi.edu/.

The fieldwork for this study will be conducted from October 1, 2013 to October 31, 2013.
