Sediment Trap Particle Flux Measured during the U.S. JGOFS Arabian Sea Process Study

A component of U.S. Joint Global Ocean Flux Study (JGOFS) is the
Arabian Sea Process Study. Eleven cruises took place aboard the R/V
Thomas G. Thompson for about sixteen months from October 1994 until
January 1996. These cruises provided seasonal coverage of the annual
monsoon and inter-monsoon cycles in the area southeast of Oman - from
where the cruises were staged. The monsoons of the Arabian Sea drive
a uniquely intense carbon cycling system, and it is the goal of JGOFS
to better understand the role of the oceans in global carbon cycling.

Particle fluxes were determined by sediment trap. Total particle flux
is measured in mg/m2/day. Particle fractions (particle sizes less
than 1 mm) of organic carbon, inorganic carbon, total nitrogen,
biogenic silicon, and aluminum are measured in percentage of total
flux.

The sediment traps were deployed in November 1994 and May 1995. Trap
depths ranged from 764 meters to 3915 meters.
Traps were deployed at the following sites:
17.69N 57.85E
17.40N 57.80E
17.20N 59.60E
15.98N 61.50E
10.00N 65.00E
