Description:
Methods are tested for computing geopotential anomalies from temperature data in the
subtropical Northeast Atlantic. Mean temperature-salinity, salinity-depth and
density-depth relationships are determined for 3 x 3° squares, using hydrographie data
from World Oceanographie Data Centre A. Geopotential anomalies computed from
observed temperatures and salinities from these mean relationships are compared with
anomalies from the original temperature and salinity data. For 0-500 dbar, geopotential
anomalies can be weil approximated, and the methods also work reasonably weil for
0-1000 dbar. The approximation is poor for 0-2000 dbar. Appropriate methods for
obtaining the best results in each 3 x 3° square are specified. The method is applied to
a particular subset of the data.
