Temperature, salinity, and nutrients from near surface shallow water samples of Mamala Bay Project MB-9, Ecosystem Response Study, (1993-1994) on Oahu, Hawaii (NODC Accession 9900064)

Water quality at 10 recreational beaches in Mamala Bay
and in the nearshore ocean were monitored over a period of 12
months in 1993-1994 to determine the impact of sewage discharges
and non-point source pollution on conditions in the bay.
Measurements included temperature, salinity, nutrients and
other parameters. The data were collected under direction
of Dr. Edward Laws of the University of Hawaii for the
Mamala Bay Study, Ecosystem Response Study, MB-9.
Samples were collected by wading into the water and filling
a 20-liter carboy with water from just below the surface in
water about one meter deep.

Samples were collected at the ten beaches on a monthly
basis from August 1993 to July 1994. The samples were
collected from just below the surface in acid-cleaned
20-liter plastic carboys at a distance from the shoreline
where the water column was one meter deep. The temperature of
the water was recorded immediately using a thermometer
calibrated to 0.1 oC and the conductivity measured with
an Extech Oyster conductivity meter. Upon return to the
laboratory, aliquots of the water were filtered through GF/F
filters for further analysis. The filtrates were used to
determine inorganic nutrient concentrations as previously
described. Samples for PC and PN analysis were collected on
precombusted GF/F filters and processed as described above.
Samples for chl a and carotenoid pigment analysis were
collected on GF/F filters and placed in liquid nitrogen
prior to extraction. The pigments were extracted by placing the
filters in approximately 5 ml of acetone for 12 h. The filters
were then ground using a Wheaton tissue grinder and the filter
residue removed by centrifugation as described in Strickland
and Parsons (1972). The extracted pigment concentrations
were then determined on a Varian 5000 high performance liquid
chromatograph (HPLC) as described by Laws et al. (1990).
