The “biological pump” is the process by which photosynthetically-produced organic matter in
the ocean descends from the surface layer to depth by a combination of sinking particles …

Deposition of marine black shales has commonly been interpreted as having involved a
high level of marine phytoplankton production that promoted high settling rates of organic …

Total organic carbon (TOC), total nitrogen (TN) and their δ13C and δ15N values were
determined from 110 sediment samples from the Ayeyarwady (Irrawaddy) continental shelf …

We report 15N/14N measurements of water column nitrate and ammonium, sinking particles,
and sediments from the Cariaco Basin, an anoxic marine basin off the coast of Venezuela …

We measured archaeal lipid distributions from globally distributed samples of freshwater,
marine, and hypersaline suspended particulate matter. Cluster analysis of relative lipid …

We present the first direct comparison and calibration of a downcore foraminiferal Mg/Ca
record to historical instrumental sea surface temperature (SST). Mg/Ca measured on the …

The development of metal stable isotopes as tools in paleoceanography requires a thorough
understanding of their modern marine cycling. To date, no Cu isotope data has been …

A long-term experiment of downward particle fluxes and currents has been initiated in 1993
on the continental slope of the Gulf of Lions (NW Mediterranean) and pursued within the …

The transgressive basal unit of the Early Cambrian black-shale sequence along the rifted
margin of the southeastern Yangtze platform hosts a wide spectrum of marine sedimentary …

The seasonality of sea surface temperatures (SST) estimated from the alkenone-[Formula:
see text] index has been a debated issue since the development of the proxy. Using a …
