Product HTML Text These two CD-ROMs hold the Surface Current (Ship Drift) Data Archive obtained by the NODC from the U.S. Naval Oceanographic Office and the World Ocean Circulation Experiment (WOCE) Subsurface Float Data released by the WOCE Subsurface Float Data Assembly Center located at the Woods Hole Oceanographic Institution. Disc 1 holds both the surface current (ship drift) data and the subsurface float data. The surface current (ship drift) data file contains over 4 million surface current observations, almost all of which were collected by the ship drift method. The subsurface float data set consists primarily of SOFAR (Sound Fixing and Ranging) and RAFOS (SOFAR spelled backwards) float trajectories. The subsurface float data has approximately 475 float trajectories and 432 float-years of data, mostly from the North Atlantic Ocean. Disc 2 holds surface current data summaries in the NODC Surface Current (Ship Drift) Long Summary format. The data are summarized by ten-degree square, one-degree square, and month for all years. For specified one-degree squares and months, the summaries provide total number of observations, number of calms, resultant current direction and speed, north and east current components, and a statistical distribution and analysis of observations by 15 speed classes and eight compass directions.
