The spread of marine anoxia on the northern Tethys margin during the Paleocene-Eocene Thermal Maximum [PDF]

, 2014
Records of the paleoenvironmental changes that occurred during the Paleocene-Eocene Thermal Maximum (PETM) are preserved in sedimentary rocks along the margins of the former Tethys Ocean and Peri-Tethys.

Simulations of ocean deoxygenation in the historical era: insights from forced and coupled models

Frontiers in Marine Science, 2023
Ocean deoxygenation due to anthropogenic warming represents a major threat to marine ecosystems and fisheries. Challenges remain in simulating the modern observed changes in the dissolved oxygen (O2).

Trends and decadal oscillations of oxygen and nutrients at 50 to 300 m depth in the equatorial and North Pacific [PDF]

Biogeosciences, 2020
A strong oxygen-deficient layer is located in the upper layers of the tropical Pacific Ocean and deeper in the North Pacific. Processes related to climate change (upper-ocean warming, reduced ventilation) are expected to change ocean oxygen and nutrient ...

Pulsed volcanism and rapid oceanic deoxygenation during Oceanic Anoxic Event 1a

Geology, 2021
Abstract Widespread oceanic anoxia, biological crises, and volcanic activity are associated with the onset of Early Aptian (ca. 120 Ma) Oceanic Anoxic Event 1a (OAE1a). Reconstructions of oceanic deoxygenation and its links to broadly contemporaneous volcanism, however, remain poorly resolved.

Challenges and Opportunities in the Integrated Economic and Oceanographic Analysis of Deoxygenation Impacts on Marine Fisheries and Ecosystems

Journal of Marine Science and Engineering
We argue that a multidisciplinary approach is essential to identify deoxygenation impacts on marine ecosystems and fisheries, bridging across the traditionally separate fields of oceanography and economics.

Deoxygenation in the oxygen minimum zone of the eastern tropical North Atlantic [PDF]

, 2009
Observations and model results both indicate increasing oxygen minimum zones (OMZ) in the tropical oceans. Here we report on record low dissolved oxygen minimum concentrations in the eastern tropical North Atlantic in fall of 2008, with less than 40 mu ...

Development of a high-resolution marine ecosystem model for predicting the combined impacts of ocean acidification and deoxygenation

Frontiers in Marine Science, 2023
An approach was developed to help evaluate and predict the combined effects of ocean acidification and deoxygenation on calcifying organisms along the coast of Japan.

The effects of changing climate on faunal depth distributions determine winners and losers

, 2014
Changing climate is predicted to impact all depths of the global oceans, yet projections of range shifts in marine faunal distributions in response to changing climate seldom evaluate potential shifts in depth distribution.

Diapycnal oxygen supply to the tropical North Atlantic oxygen minimum zone [PDF]

, 2012
The replenishment of consumed oxygen in the open ocean oxygen minimum zone (OMZ) off northwest Africa is accomplished by oxygen transport across and along density surfaces, i.e. diapycnal and isopycnal oxygen supply. Here the diapycnal oxygen supply is
