Field Activity 2008-009-FA

Identifier

2008-009-FA

Alternate names

HE0806; H-2-08-AR, H-02-08-AR

Purpose

Collect bathymetry, chirp sub-bottom, and gravity data as well as break ice for a second ship (LOUIS S. ST. LAURENT) as part of delimiting the boundary of the U.S. extended continental shelf in the Eurasian Basin of the Arctic Ocean.

Location

Canada Basin, United States, Canada, North America, Arctic Ocean;

Summary

There were 5146 km of tracklines (multibeam, sub-bottom and gravity). Total area imaged was 39,311 km2 with the SeaBeam 2112. 11 stations were occupied for CTD and 10 stations for phytoplankton analysis.

Comments

This is part of a two-ship operation with the Canadian ice-breaker LOUIS S. ST. LAURENT. Project = Interagency Task Force Cooperative, Interagency Task Force Cooperative
