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 …

The deep sea, the largest ecosystem on Earth and one of the least studied, harbours high
biodiversity and provides a wealth of resources. Although humans have used the oceans for …

This chapter addresses the biogeochemical cycles of carbon dioxide (CO2), methane (CH4),
and nitrous oxide (N2O). The three greenhouse gases have increased in the atmosphere …

Uncovers the Key Role Microbes Play in the Transformation of Oxidizable and Reducible
MineralsMany areas of geomicrobial processes are receiving serious attention from …

Since the mid-1980s, our understanding of nutrient limitation of oceanic primary production
has radically changed. Mesoscale iron addition experiments (FeAXs) have unequivocally …

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 …

There is growing recognition that microalgae are among the most productive biological
systems for generating biomass and capturing carbon. Further efficiencies are gained by …

Iron is an essential nutrient that regulates productivity in~ 30% of the ocean. Compared with
deep (> 2000 meter) hydrothermal activity at mid-ocean ridges that provide iron to the …

Ecosystem processes are important determinants of the biogeochemistry of the ocean, and
they can be profoundly affected by changes in climate. Ocean models currently express …

The availability of iron limits primary productivity and the associated uptake of carbon over
large areas of the ocean. Iron thus plays an important role in the carbon cycle, and changes …
