HOT Physical Oceanography IES data

Scientists working within the Hawaiian Ocean Time-series (HOT) project, hahana.soest.hawaii.edu/hot/, have been making repeated observations of the hydrography, chemistry and biology at a station north of Hawaii since October 1988. The objective of this research is to provide a comprehensive description of the ocean at a site representative of the central North Pacific Ocean. Cruises are made approximately once a month to Station ALOHA, the HOT deep-water station (22 45'N, 158W) located about 100 km north of Oahu, Hawaii.

Measurements of the thermohaline structure, water column chemistry, currents, primary production and particle sedimentation rates are made over a 72-hour period on each cruise. The IES data was proccessed using methods explained in: 1991 Fields, E., K. Tracey, D.R. Watts.
