Projects aboard (3)

OSBL anisotropy - Waverider

The overarching project is to observe and quantify the anisotropy of the Ocean Surface Boundary Layer with specially equipped Lagrangian floats. Observations will be conducted near the Ocean Climate Station P. The first cruise of the series is to deploy a Waverider buoy to provide essential surface wave monitoring during the project. Intended as ancillary project to an OOI cruise.
