The world's eastern boundary upwelling systems (EBUSs) contribute disproportionately to
global ocean productivity and provide critical ecosystem services to human society. The …

Ecosystem productivity in coastal ocean upwelling systems is threatened by climate change.
Increases in spring and summer upwelling intensity, and associated increases in the rate of …

Deoxygenation is commonly observed in oceans and lakes but less expected in shallower,
flowing rivers. Here we reconstructed daily water temperature and dissolved oxygen in 580 …

Existing redox classifications and the calibrations of elemental proxies to modern
environmental redox scales are in need of re-evaluation. Here, we review environmental …

Ocean models predict a decline in the dissolved oxygen inventory of the global ocean of one
to seven per cent by the year 2100, caused by a combination of a warming-induced decline …

The Ocean plays a central role in Earth's climate and has absorbed 93% of the extra energy
from the enhanced greenhouse effect and approximately 30% of anthropogenic carbon …

The effect of Ocean Acidification (OA) on marine biota is quasi-predictable at best. While
perturbation studies, in the form of incubations under elevated pCO2, reveal sensitivities and …

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 …

Nutrient fluxes to coastal areas have risen in recent decades, leading to widespread hypoxia
and other ecological damage, particularly from nitrogen (N). Several factors make N more …

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