Clay mineral and bulk chemical (Si, Al, K, Mg, Sr, La, Ce, Nd) analyses of terrigenous surface sediments on the Siberian-Arctic shelf indicate that there are five regions with distinct, or endmember, sedimentary compositions. The formation of these g

We present particulate barium data collected using sequencing sediment traps in the Ross Sea region of the Southern Ocean. Data were collected in 1991–92, 1994–95, and 1996–98 from two separate field programs. Samples were collected at ∼200 m

Due to the major role played by diatoms in the biological pump of CO2, and to the presence of silica-rich sediments in areas that play a major role in air–sea CO2 exchange (e.g. the Southern Ocean and the Equatorial Pacific), opal has a strong pote

An array of five bottom-tethered moorings with 19 PARFLUX time-series sediment trap at three depths (1 and 2 km below the surface, and 0.7 km above the sea-floor) was deployed in the western Pacific sector of the Southern Ocean, along 170°W. The fiv

The record for plankton biomarkers in sediment trap samples from a one-year experiment in the central Arabian Sea (AS4: 15°59′N 61°30′E) shows variations that reflect changing biological conditions in surface waters. Particulate fluxes of C37

As part of the USJGOFS-AESOPS program, we deployed an array of moored sediment traps and determined the composition and vertical flux of particulate matter through the water column of the continental shelf environment of the Ross Sea. We deployed two

As a part of the US-JGOFS Arabian Sea Process Study (ASPS), we deployed a mooring array consisting of 16 Mark-7G time-series sediment traps on five moorings, each in the mesopelagic and interior depths in the western Arabian Sea set along a transect

Organic carbon fluxes in the Arabian Sea were measured as a function of depth, season and distance from the coast of Oman. We present here a compilation of measurements of primary production, water-column export flux and sediment accumulation of orga

In the central equatorial Pacific, settling particles collected with sediment traps have Al/Ti values greater than those of a typical crustal source. The Al/Ti values of the sediment trap material are not well correlated with either the flux of organ
