        abstract:  The HOT program makes repeated observations of the physics, biology and chemistry at a site approximately 100 km north of Oahu, Hawaii. In support of the quasi-monthly shipboard work, the HALE-ALOHA mooring was installed in January 1997. The name is derived from the Hawaii Air-sea Logging Experiment (HALE, or house in Hawaiian language) ALOHA (A Long-term Oligotrophic Habitat Assessment). This CTD/GTD device was placed at 50 m depth in each mooring cycle. The device consists of a Seabird Seacat 16DO CTD capable of measuring temperature, salinity, pressure and oxygen. Attached to this CTD is a gas tension device (GTD) designed and built by Dr. Bruce Johnson at Dalhousie University in Halifax, Nova Scotia, Canada. The GTD deployed at 50 m, provides a novel method of inferring dissolved N2 and O2 gas concentrations in seawater based on a local measurement of gas tension, water temperature and salinity. This data set ends in April 1998.
        purpose:  The objective is to support studies of the earth as a system of interrelated physical, chemical, and biological processes that act together to regulate the habitability of our plantet. The first goal is to understand the earth-ocean-atmosphere system and how it functions. The second goal is to describe, and eventually predict, major cause-and-effect relationships. The former goal is focused on physical oceanographic processes and the latter on biogeochemical processes. The objective of the physical component of HOT is to describe and understand the ocean climate and variability at a deep-water site in the North Pacific subtropical gyre near Hawaii. This requires a long time series of physical oceanographic variables, including water mass properties and currents, supporting and complementing the objectives of the biogeochemical component of HOT. The objective of the biogeochemical component is summed up in the acronym Station ALOHA (A Long-term Oligotrophic Habitat Assessment) as well as its part in the larger picture (ocean-atmosphere-earth system).
        credit:  HOT was initiated and funded through grants from the National Science Foundation under the auspices of the Joint Global Ocean Flux Study (JGOFS) and the World Ocean Circulation Experiment (WOCE). The field phase of these programs has ended, but support from the Ocean Sciences Division of NSF has enabled continuation of our basic HOT measurement program until mid-2001. The PO component contributes to the objectives of the World Climate Research Programme (WCRP) Climate Variability and Predictability (CLIVAR) Programme by providing information on interannual to decadal variability of the North Pacific Ocean.

        supplementalInformation:  Note: Metadata for this accession were extracted from a legacy database maintained by the U.S. National Oceanographic Data Center (NODC). The design of the database did not exactly reflect the FGDC Content Standard for Digital Geospatial Metadata (CSDGM). Principal Investigator (PI) and organization contact information accurately represents all available information from the legacy database at the time that this description was created. However, proper attribution of a PI to a specific institution or the role (submitting or collecting) taken by an institution may not be correct due to inexact mapping between fields in the legacy database and the CSDGM. Due to this uncertainty, the contact information was initially recorded in the Supplemental Information element of the CSDGM description. To develop more accurate metadata, NCEI reviews metadata for all accessions on an ongoing basis. Points of contact for this data set include: Contact info: Agency: UNIVERSITY OF HAWAII PI: N/A Address: address: 2525 CORREA ROAD, HIG331 city: HONOLULU state: HI postal: 96822 country: UNITED STATES
