"The Expendable Bathythermograph (XBT) has been used by oceanographers for many years to obtain information on the temperature structure of the ocean to depths of up to 1500 meters. The XBT... is a probe which is dropped from a ship and measures the temperature as it falls through the water. Two very small wires transmit the temperature data to the ship where it is recorded for later analysis. The probe is designed to fall at a constant rate, so that the depth of the probe can be inferred from the time since it was launched. By plotting temperature as a function of depth, the [National Oceanic and Atmospheric Administration and U.S. Geological Survey] scientists can get a picture of the temperature profile of the water." (<http://www.aoml.noaa.gov/phod/uot/uot_xbt.html>). The XBT device and location where it was dropped was engineered by the USGS Science Cruise 03008 in collaboration with NOAA Research Cruise RB0303 from 18 February to 7 March 2003, Leg II of III. (Leg I and III: 20020924 to 20020930 and 20030828 to 20030904, respectively). This data set is in shapefile format.
Purpose:
To show the coordingate system location stations using the longitude, the latitude, and the dates where and when XBT equipment was launched.
