There is overwhelming evidence that riverine
nutrients drive both the production of
phytoplankton and the size of the hypoxic
zone on the inner shelf.
Characterization and long-term trends of hypoxia in the northern Gulf of Mexico: Does the science support the action plan?
long-term trends of hypoxia the northern Gulf of Mexico
2016/5/18
We update and reevaluate the scientific information on the distribution, history, and causes of continental
shelf hypoxia that supports the 2001 Action Plan for Reducing, Mitigating, and Controlling ...

Nutrient loading and meteorological conditions explain interannual variability of hypoxia in Chesapeake Bay
Nutrient loading meteorological conditions Chesapeake Bay
2014/4/2
We use geostatistical universal kriging and conditional realizations to provide the first quantitative estimates,
with robust estimates of uncertainties, of the seasonal and interannual variability i...
Hypoxia and nitrogen processing in the Baltic Sea water column
Hypoxia nitrogen processing Baltic Sea water column
2012/4/4
Steep redoxclines form between oxic surface water and the stagnant, sulfidic hypolimnion in the eutrophied,
brackish water Baltic Sea. Nitrification, denitrification, and anammox were measured at and...
Sedimentary phosphorus dynamics and the evolution of bottom-water hypoxia: A coupled benthic–pelagic model of a coastal system
Sedimentary phosphorus dynamics a coastal system
2011/4/8
The present study examines oxygen and phosphorus dynamics at a seasonally hypoxic site in the Arkona basin
of the Baltic Sea. A coupled benthic–pelagic reactive-transport model is used to describe th...
Aerobic respiration and hypoxia in the Lower St. Lawrence Estuary: Stableisotope ratios of dissolved oxygen constrain oxygen sink partitioning
Aerobic respiration and hypoxia Lawrence Estuary dissolved oxygen constrain oxygen sink partitioning
2010/4/17
We measured the concentration and the stable isotope ratios of dissolved oxygen in the water column in the Estuary and Gulf of St. Lawrence to determine the relative importance of pelagic and benthic ...
Sulfide exposure accelerates hypoxia-driven mortality
Sulfide exposure accelerates hypoxia-driven mortality
2010/4/17
The effect of the presence of sulfide on the survival of benthic organisms under hypoxia was tested using a meta-analysis of published experimental results evaluating the effects of the presence of hy...
Estuarine oxygen dynamics: What can we learn about hypoxia from long-time records in the Delaware Estuary?
Estuarine oxygen dynamics Delaware Estuary
2010/4/16
Hypoxia and anoxia occurred in the upper Delaware Estuary throughout much of the 20th century and
diminished over the past several decades. I reviewed 30 yr of data from my laboratory’s research effo...

Under certain conditions, sediment cores from coastal settings subject to hypoxia can yield records of environmental changes over time scales ranging from decades to millennia, sometimes with a resolu...
The intensity, duration and frequency of coastal hypoxia (oxygen concentration <63 μM) are increasing due to human alteration of coastal ecosystems and changes in oceanographic conditions due to globa...

Gulf hypoxia Marine modification
2009/5/6
This study examines potential marine modification of two classes of terrestrial influence on Gulf hypoxia: (1) the flow of nutrient-rich water from the Mississippi/Atchafalaya River Basin and (2) the ...
