Temperature profiles and current measurements from the Nathaniel B. Palmer during the 1997 Dovetail cruise in the Southern Ocean (NCEI Accession 9900243)

The separate files contain different portions of the overall dataset as follows:

u - east-west current data with speed in m/s. These data are in the form of a two-dimensional matrix with time increasing to the right and depth increasing downward, and so present a time series of vertical profiles in u. Each column is a vertical current profile at a fixed time, with the time given by the time file described below.

v - north-south current data in the same format as described for u.

time - time as decimal day, where 1 January is day '0'. In other words, noon on 1 January has a decimal time of 0.500. These data are in the form of a row vector with time increasing toward the right. The values give the times when u and v in the corresponding columns were recorded.

Lat - latitude from 0 to +/-90 degrees, where a negative value indicates southern hemisphere. These data are in the form of a row vector, where the points are arranged in order of increasing time to the right. Each point gives the latitude at which u and v in the corresponding columns were recorded.

Lon - longitude from 0-360 degrees. This file is structured the same as for the lat file.

Depth - depths in meters of current speed values. These data are in the form of a column vector with depth increasing downward. Each point gives the depth represented by the corresponding values of u and v. Current speeds were measured using vertical bin sizes of 8 meters, and the depths given are for the midpoint of each 8-meter bin.

To provide a simple example for use of these data, plotting either the u or v matrix using time to scale the abscissa and depth to scale the ordinate will return a time series plot of vertical profiles of u or v.
