**1. [Abstract]{.underline}:** The National Climatic Data Center has is
its archive the historical dataset TD-1148 (Navy Marine Surface
Observations). Major parameters include temperature, dew point, sea
surface temperature, wind speed and direction, and cloud, wave and swell
data. The coverage area includes the entire globe and data begins in
1915 and continues through 1975.
