Description

Pioneer biogeochemical data show a clear contrast between a warm eddy ring and shelf waters. The eddy signature in the data is also a great opportunity to visualize how and eddy can entrain shelf water along its periphery, offshore and below the surface.

Water Properties:
Shelf water : cold (12–14 °C), fresh (34–35.7 g/kg), high oxygen (>210 ?mol/kg), and high CDOM.
Eddy: warm, saline, low oxygen, and low CDOM ring water.
