Pelagic food webs drive a flux of> 10 x 1012 kg C yr− 1 that exits surface waters, mostly via
sinking particles through the ocean's" biological pump." Much of this particle flux is …

The study of vertical migrations in aquatic organisms has a long and colourful history, much
of it to do with the effects of changing sampling technology on our understanding of the …

Several explanations for the 200 to 280 ppm glacial/interglacial change in atmospheric CO2
concentrations deal with variations in southern ocean phytoplankton productivity and the …

The years 1995 to 2000 experienced the highest level of North Atlantic hurricane activity in
the reliable record. Compared with the generally low activity of the previous 24 years (1971 …

The relationship between primary production in the surface ocean and export of particulate
organic carbon (POC) on sinking particles is examined in studies that have utilized 234Th as …

The ocean's biological carbon pump is a key component of the global carbon cycle. Only a
small fraction of the carbon fixed by primary production is exported to the deep ocean, yet …

Based on balanced chemical equations for the production of proteins, polysaccharides,
lipids and nucleic acids from inorganic precursors and reported estimates of the composition …

The disequilibrium between the particle-reactive tracer 234 Th (t 1 2= 24.1 days) and its
soluble parent, 238 U, was used to examine Th scavenging and export fluxes during the US …

We present new empirical and mechanistic models for predicting the export of organic
carbon out of the surface ocean by sinking particles. To calibrate these models, we have …

A reconstruction of the prebomb Δ14C distribution in the tropical Pacific using data from old
coral heads shows that surface waters with the lowest Δ14C content are found distinctly …
