Primary productivity in middle loch of Pearl Harbor, Oahu, Hawaii, collected by oceanography students from the Leeward Community College from 1975 to 1996 (NCEI Accession 0000655)

Published by NOAA National Centers for Environmental Information | U.S. Census Bureau, Department of Commerce | Catalog Last Checked: May 06, 2026 at 12:38 AM | Dataset Last Updated: March 17, 2013 at 12:00 AM
Primary productivity data were collected in middle loch of Pearl Harbor, Hawaii, from 20 November 1975 to 27 November 1996. Data were collected by Leeward Community College and include results obtained employing the Winkler titration method with initial bottles, light bottles, and dark bottles. Data include rates of net productivity, gross productivity, and respiration. Time-series investigations were conducted at two hour intervals, although reduced to four sessions between 0830 to 1630 hours by inclement weather, yielded patterns resembling those observed previously in fall of 1975 and 1980 and spring of 1977. Data from all years is provided within this set.
