Record #187261:

Surface circulation at the tip of the Antarctic Peninsula from drifters / Andrew F. Thompson, and 4 others.

Title: Surface circulation at the tip of the Antarctic Peninsula from drifters / Andrew F. Thompson, and 4 others.
Author(s): Thompson, Andrew F.
Date: 2009.
In: Journal of Physical Oceanography. (2009.), Vol. 39(1) (2009)
Abstract: Provides detailed description of surface circulation in north-western Weddell Sea using data from array of 40 surface drifters deployed in February 2007, drogued at 15 m depth, as part of Antarctic Drifter Experiment: Links to Isobaths and Ecosystems (ADELIE) project. Dominant feature east of peninsula is Antarctic Slope Front characterized by 20 cm s⁻¹ current following 1000-m isobath. Slope front bifurcates on encountering South Scotia Ridge with drifters either carried westward into Bransfield Strait; following 1000-m isobath to east along southern edge of South Scotia Ridge; or becoming entrained in large-standing eddy over South Scotia Ridge. Drifters are strongly steered by contours of f/h (Coriolis frequency/depth), and eddy-mean decomposition of drifter velocities indicates that shear in mean flow makes dominant contribution to dispersion in along-f/h direction, whereas eddy processes are more important in dispersing particles across contours on f/h. Results suggest that circulation near tip of Antarctic Peninsula may influence ecosystem dynamics in Southern Ocean through Antarctic krill transport and export of nutrients.
