Vertical Fine Structure Beneath the Ice of the Western Antarctic Peninsula Shelf in Austral Winter 2001 – NBP0104

Vertical Structure – Vertical Fluxes

The winter cruise platform was more stable than fall due to ice cover

The Surface Mixed Layer

Surface mixed layer depth

An example of a layered vertical structure in main pycnocline

Double Diffusive Convection

Possible mechanisms for pycnocline layers

Where the steps occurred

Strong layering within pycnocline present at a few stations

Often Interesting Structure around Tmax

A Possible Scenario…
