Coastal upwelling regimes associated with eastern boundary currents are the most
biologically productive ecosystems in the ocean. As a result, they play a disproportionately …

The sulfur cycle is an important, although understudied facet of today's modern oxygen
minimum zones (OMZs). Sulfur cycling is most active in highly productive coastal OMZs …

A major percentage of fixed nitrogen (N) loss in the oceans occurs within nitrite-rich oxygen
minimum zones (OMZs) via denitrification and anammox. It remains unclear to what extent …

We review here the available information on methane (CH 4) and nitrous oxide (N 2 O) from
major marine, mostly coastal, oxygen (O 2)-deficient zones formed both naturally and as a …

Nitrous oxide (N 2 O) and NO y (nitrous acid (HONO)+ nitric oxide (NO)+ nitrogen dioxide
(NO 2)) are released as byproducts or obligate intermediates during aerobic ammonia …

In Eastern Boundary Upwelling Systems nutrient-rich waters are transported to the ocean
surface, fuelling high photoautotrophic primary production. Subsequent heterotrophic …

Marine oxygen minimum zones (OMZs) are intrinsic water column features arising from
respiratory oxygen demand during organic matter degradation in stratified waters. Currently …

Nitrite is a central intermediate in the marine nitrogen cycle and represents a critical juncture
where nitrogen can be reduced to the less bioavailable N2 gas or oxidized to nitrate and …

Oxygen minimum zones (OMZs), known as suboxic layers which are mainly localized in the
Eastern Boundary Upwelling Systems, have been expanding since the 20th" high CO 2" …

Dissolved CH 4 was measured in the water column at the Boknis Eck (BE) time series
station in the Eckernförde Bay (SW Baltic Sea) on a monthly basis from June 2006 to …
