This review provides an integrated synthesis with timelines and evaluations of ecological
responses to eutrophication in Chesapeake Bay, the largest estuary in the USA. Analyses of …

The marine areas of South America (SA) include almost 30,000 km of coastline and
encompass three different oceanic domains—the Caribbean, the Pacific, and the Atlantic …

Water masses can become undersaturated with oxygen when natural processes alone or in
combination with anthropogenic processes produce enough organic carbon that is …

Coastal hypoxia (defined here as< 1.42 ml L− 1; 62.5 μM; 2 mg L− 1, approx. 30% oxygen
saturation) develops seasonally in many estuaries, fjords, and along open coasts as a result …

Rates of nitrate (NO 3-) reduction to nitrogen gas (N 2) and ammonium (NH 4+) were
measured in August and December 1999 on intact cores (Laguna Madre and Baffin Bay …

Benthic foraminifers inhabit a wide range of aquatic environments including open marine,
brackish, and freshwater environments. Here we show that several different and diverse …

The main pathways of sulfide oxidation in marine sediments involve complex interactions of
chemical reaction and microbial metabolism. Sulfide becomes partly oxidized and bound by …

The interplay between the oxygen minimum zone and remotely-forced oxygenation
episodes determines the fate of the benthic subsystem off the Central Peruvian coast. We …

Dissimilatory nitrate reduction processes including denitrification, anaerobic ammonium
oxidation (ANAMMOX), and dissimilatory nitrate reduction to ammonium (DNRA) are crucial …

This article presents data on the isotopic composition of pore water ammonium and Norg in
the anoxic sediments of the Santa Barbara Basin and the Eastern Subtropical North Pacific …
