HOT site
In 1988, two deep ocean time-series hydrostations were established with support from the U.S. National Science Foundation (NSF):
one in the western North Atlantic Ocean near the historical Panulirus Station (Bermuda Atlantic Time-series Study [BATS];
Michaels and Knap, 1996) and the other in the subtropical North Pacific Ocean near Hawaii (Hawaii Ocean Time-series [HOT];
Karl and Lukas, 1996). These programs were established and are currently operated by scientists at Bermuda Biological Station for Research and the University of Hawaii, respectively.
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.
To get an overview about the data available in the following section, please have a look at the map and the variable/parameter profiles (.pdf document).
In order to present properly the results Ocean Data View (Reiner Schlitzer, Alfred Wegener Institute for Polar and Marine Research) has been applied.
Data are available as tab-delimited .txt files in ASCII format. If you have comments on that, please let me know (Nicolas Dittert, WDC-MARE).
All ORFOIS related data with respect to HOT are continuously updated.
Whenever you use data of the ORFOIS data compilation that refer to the HOT data collection, please quote the citations of the
