The epoch of the Anthropocene, a period during which human activity has been the
dominant influence on climate and the environment, has witnessed a decline in oxygen …

Oxygen minimum zones (OMZs) and oxygen limited zones (OLZs) are important
oceanographic features in the Pacific, Atlantic, and Indian Ocean, and are characterized by …

Climate models with biogeochemical components predict declines in oceanic dissolved
oxygen with global warming. In coastal regimes oxygen deficits represent acute ecosystem …

In the modern ocean, oxygen minimum zones (OMZs) are potential traces of a primitive
ocean in which Archean bacteria lived and reduced chemical anomalies occurred. But …

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 …

Oxygen minimum zones (OMZs) as found in the Eastern Pacific and Indian Ocean are
biogeochemical hot spots with a disproportionately large role in the marine nitrogen cycle …

Abstract Every 2–7 years, El Niño events trigger a strong decrease in phytoplankton
productivity off Peru, which profoundly alters the environmental landscape and trophic chain …

The seasonal variability of surface chlorophyll in the northern Humboldt Current System is
studied using satellite data, in situ observations and model simulations. The data show that …

Background Oxygen minimum zones (OMZs) are expanding in the World Ocean as a result
of climate change and direct anthropogenic influence. OMZ expansion greatly affects …

Multiple eukaryotic clades make their first appearance in the fossil record between~ 810 and
715Ma. Molecular clock studies suggest that the origin of animal multicellularity may have …
