U.S. Joint Global Ocean Flux Study
http://usjgofs.whoi.edu/
U.S. Joint Global Ocean Flux Study
The United States Joint Global Ocean Flux Study was a national component of international JGOFS and an integral part of global climate change research.
The U.S. launched the Joint Global Ocean Flux Study (JGOFS) in the late 1980s to study the ocean carbon cycle. An ambitious goal was set to understand the controls on the concentrations and fluxes of carbon and associated nutrients in the ocean. A new field of ocean biogeochemistry emerged with an emphasis on quality measurements of carbon system parameters and interdisciplinary field studies of the biological, chemical and physical process which control the ocean carbon cycle. As we studied ocean biogeochemistry, we learned that our simple views of carbon uptake and transport were severely limited, and a new "wave" of ocean science was born. U.S. JGOFS has been supported primarily by the U.S. National Science Foundation in collaboration with the National Oceanic and Atmospheric Administration, the National Aeronautics and Space Administration, the Department of Energy and the Office of Naval Research. U.S. JGOFS, ended in 2005 with the conclusion of the Synthesis and Modeling Project (SMP).

U.S. JGOFS Arabian Sea
<p>The U.S. Arabian Sea Expedition which began in September 1994 and ended in January 1996, had three major components: a U.S. JGOFS Process Study, supported by the National Science Foundation (NSF); Forced Upper Ocean Dynamics, an Office of Naval Research (ONR) initiative; and shipboard and aircraft measurements supported by the National Aeronautics and Space Administration (NASA). The Expedition consisted of 17 cruises aboard the R/V Thomas Thompson, year-long moored deployments of five instrumented surface buoys and five sediment-trap arrays, aircraft overflights and satellite observations. Of the seventeen ship cruises, six were allocated to repeat process survey cruises, four to SeaSoar mapping cruises, six to mooring and benthic work, and a single calibration cruise which was essentially conducted in transit to the Arabian Sea.</p>

<h2>Zooplankton displacement volume measurements of Bongo samples collected during Arabian Sea Cruise TN054 (Process Cruise 7).</h2>

Zooplankton samples were collected in oblique Bongo net tows which
covered approximately the upper 200 m of the water column. The Bongo
frames were 60 cm diameter and were fitted with 153 and 335 um Nitex
nets. A General Oceanics flow meter model 2030R was secured in the net
mouth for the determination of volume filtered. The maximum sampling
depth of each tow was determined from a Wildlife Computers Mk3e Time
Depth Recorder (TDR) attached to the net frame.
The Bongo nets were towed beside the ship at approximately 1.5 to 2
knots through the water. Winch speed was generally 30 meters/minute
during deployment and 20 meters/minute during recovery. On board the
ship, samples from the 153 um net were split in a modified Folsom
Splitter which split the sample into four parts consisting of 50%, 20%,
20% and 10%. In general, 10% was used for dry weight measurements, 20%
was preserved for collaborating scientists (Prell, McDonough) and 70%
was preserved for displacement volume measurements and taxonomic
analysis. The portion of each sample for dry weight measurement was
poured through nested sieves of 1050, 560, 200 and 64 um mesh. Each
size fraction was then placed on a pre-weighed 9 cm Whatman #1
qualitative filter. The filters were stored in glassine envelopes and
placed in a drying oven at 55 to 6 degrees C. Near the end of the
cruise the dry weight samples were sealed in cracker tins with
desiccant for transport to the laboratory where they were later weighed
on a Mettler H20 balance. The samples from the 335 um nets were
briefly scanned under a Wild M5 dissecting microscope on the ship to
assess the dominant zooplankton taxa and then preserved in their
entirety in 4% buffered formaldehyde/seawater for laboratory
measurement of displacement volume.
In the laboratory, displacement volumes were determined following the
methods described by Ahlstrom and Thrailkill (1963), and Kane (1982).
In general, samples were poured into 500 or 1000 ml graduated
cylinders, depending on the volume of plankton present, the volume of
plankton and water was measured, then the sample was poured through a
150 um sieve, allowed to drain, and the volume of water measured. The
difference between the two volume measurements was the displacement
volume. The displacement volume of each sample was divided by the
volume filtered by the net (m^3) and the result is reported here in
units of cc/m^3.
The size specific dry weights from the 9 cm filters are reported in
units of mg/m^3. The size ranges are labeled in the data file as
zp_dw_1, zp_dw_2, zp_dw_3, zp_dw_4 and zp_dw_T, and correspond to size
fractions of 64-200 um, 200-560 um, 560-1050 um, greater than 1050 um
and total dry weight which is the sum of the four size fractions. It
is important to note that these size ranges are not identical to those
reported by Wishner or Roman for other cruises and samples.

Bongo Nets
Bongo Nets
PI Supplied Instrument Name: Bongo Nets PI Supplied Instrument Description:The Bongo frames were 60 cm diameter and were fitted with 153 and 335 um Nitex nets. Instrument Name: Bongo Net Instrument Short Name:Bongo Net Instrument Description: A Bongo Net consists of paired plankton nets, typically with a 60 cm diameter mouth opening and varying mesh sizes, 10 to 1000 micron. The Bongo Frame was designed by the National Marine Fisheries Service for use in the MARMAP program. It consists of two cylindrical collars connected with a yoke so that replicate samples are collected at the same time. Variations in models are designed for either vertical hauls (OI-2500 = NMFS Pairovet-Style, MARMAP Bongo, CalVET) or both oblique and vertical hauls (Aquatic Research). The OI-1200 has an opening and closing mechanism that allows discrete "known-depth" sampling. This model is large enough to filter water at the rate of 47.5 m3/minute when towing at a speed of two knots.
