We present observations of high frequency current |
|
variability on the continental shelf and the slope of the |
|
Antarctic Peninsula using Lagrangian surface drifters |
|
deployed as part of the Antarctic Drifter Experiment: |
|
Links to Isobaths and Ecosystems (ADELIE) project. Here |
|
we focus on high frequency processes such as tides and |
|
inertial oscillations that are typically smoothed out of |
|
large scale spatially averaged, and/or temporally |
|
averaged, observed current fields. We investigate the |
|
role that this class of motion plays in the transport of |
|
physical or biogeochemical properties. Lateral |
|
displacements on the |
|
shelf and slope are found to be larger than displacements |
|
in deeper waters where tidal currents are negligible. We |
|
apply this result in a parameterization of the lateral |
|
dispersion during an off line drifter modeling study. The |
|
outcome is an improvement on the modeling of Lagrangian |
|
drifting particles compared with a standard random walk |
|
scheme. |
