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 …

Macroscopic aggregates of detritus, living organisms and inorganic matter known as marine
snow, have significance in the ocean both as unique, partially isolated microenvironments …

For the past 3.8 billion years, the geochemistry of the Earth's surface-its atmosphere, waters
and exposed crust-has been determined by the presence of biota. Photosynthetic organisms …

Metals in the hydrological cycle represent a very broad subject covering all parts of the
geological cycle. The present version of this book, therefore, would not have been possible …

It would not have been possible for me to write the three editions of this book without a
double dose of extraordinary fortune: to have been part of the Woods Hole scientific …

AT ocean trenches, sea-floor sediments may either be scraped off the subducting plate, or
accompany it into the mantle. Some of the subducted sediment may then be recycled to the …

Rapid mass sinking of cells following diatom blooms, observed in lakes and the sea, is
argued here to represent the transition from a growing to a resting stage in the life histories …

We compiled and standardized sediment trap data below 1000 m depth from 52 locations
around the globe to infer the implications of the Armstrong et al.[2002]“ballast” model to the …

Use of sedimentary organic carbon concentrations as a record of paleoceanographic
conditions is complicated by an insufficient understanding of the mechanisms controlling …

During the past decade data from a variety of sources have been obtained which show
conclusively that the relatively rare, large particles sinking through the water column are …
