Hawaiʻi Ocean Time-series (HOT)

Scientists working within the Hawaiʻi Ocean Time-series (HOT) program have been making repeated observations of the hydrography, chemistry, and biology at a station north of the Hawaiian islands 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 ("A Long-term Oligotrophic Habitat Assessment"), a deep-water station located about 100 km north of the island of Oʻahu. In addition, HOT conducts routine measurements at a number of other data collection sites around Station ALOHA and Oʻahu.
