Description

Sea Surface Temperature from Hard Hat Precision Thermistor

Subsurface, bulk temperature measurements were taken with a precision
thermometer mounted in a surface float made from a foam-filled hard
hat. The thermometer is at a nominal depth of 5cm and the float has
been deployed at most stations. The thermometer is sampled every second,
and 20-s averages are logged.

The ASCII "HAT" files contain measurements from a precision thermistor
supported by a surface-following float, made from a "hard hat" filled
with foam.

The measurement is at a nominal depth of 5 cm. Calibration is traceable
to NIST standards.

There are 52 ASCII .HAT data files with names of: 04mmddx.hat
where 04 = year (2004)
where mm = month (03 or 04 for March and April)
where dd = date
where x = a/b/c for first/second/third data collection for a given day
