Water column data were collected with conductivity-temperature-depth (CTD) profilers 1 h before sunrise and 1 h after sunset on each survey day and with expendable bathythermographs (XBTs) during daylight hours at intervals of ~55 km.

According to measurements by an array of autonomous free-floating ocean floats called Argo, as well as by earlier devices called expendable bathythermographs, or XBTs, that were dropped from ships to obtain temperature data, ocean heat content has increased over the last 16 years.
Like all ships of her class, the Mary Sears has a length of 329 feet and a displacement of 4,700 tons, and she carries the latest in over-the-side sensors and sampling equipment, including bathythermographs, bottom corers and seismic equipment.
[FIGURE 1 OMITTED] Bottom temperature, cold pool, and depth Water temperature and depth profiles were collected at each station by using bathythermographs attached to the headrope of the bottom trawl net (expendable models before 1993 and microbathythermographs in later years).
When they spotted one, they had the pilot hover a few feet above the surface while one member of the team dropped an expend able bathythermograph, or XBT, out of one side of the helicopter, and another dropped a grounding wire out of the other side.
Nor even the fact that a network of 3,175 bathythermograph buoys have found that the heat content of the ocean has been dropping for the last five years.
Gear used included an Isaacs-Kidd midwater trawl net, bongo net, Conductivity-Temperature-Depth (CTD) probes, Expendable Bathythermograph (XBT), and a sea surface temperature recorder.
