Hawaii Ocean Time-series Program
Scientists working within the Hawaiian Ocean Time-series (HOT)
project 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.
