The small-scale survey uses a Bell 206 long-ranger helicopter to take ~7 hydrographic stations on our main section across the continental slope northwest of Alert (green dots in the figure). These are roughly coincident with stations taken in the early 1990’s by J. Newton and colleagues as part of the ICESHELF project.
If time permits, a second line of stations are taken east from the main section (3 green dots in the figure).
We want to measure the eastward-flowing boundary current and also determine water property changes that occur in the transition from the deep Arctic Ocean basin to the shallow continental shelf. |
