Latest Conditions:

Click on the graph icons below to see time series plots of the listed variables. The latest conditions are in local time but all plots are in GMT(Summer EDT is 4 hours behind GMT; Winter EST is 5 hours behind GMT; Atlantic AST is always 4 hours behind GMT).

We follow the convention that depth is measure positive "down". That's why parameters like wind speed have negative depths attached to them! The latest eastward and northward subsurface currents are displayed at a subset of available depths; no plots are presently available for current velocity vectors below 2m.

Wind and Residual Ocean Currents

Measured winds and currents which are low-pass filtered to remove tidal currents. Winds at 4 m above sea surface, surface currents at a depth of 2 m, and doppler currents at 4 meter bins from 10 meters to a maximum of 126 meters.
