Seasonal and interannual variability in the hydrology and geochemistry of an outlet glacier of the Greenland Ice Sheet
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-02)
In the spring and summer within the ablation zone of the Greenland Ice Sheet (GrIS), meltwater drains to the ice sheet bed through an evolving network of efficient channelized and inefficient distributed drainage systems. ...
Methods of oil detection in response to the Deepwater Horizon oil spill
(The Oceanography Society, 2016-09)
Detecting oil in the northern Gulf of Mexico following the Deepwater Horizon oil spill presented unique challenges due to the spatial and temporal extent of the spill and the subsequent dilution of oil in the environment. ...
Erosion of organic carbon in the Arctic as a geological carbon dioxide sink
Soils of the northern high latitudes store carbon over millennial timescales (103 yrs) and contain approximately double the carbon stock of the atmosphere1-3. Warming and associated permafrost thaw can expose soil organic ...
Hydrologic control of carbon cycling and aged carbon discharge in the Congo River basin
The age of organic material discharged by rivers provides information about its sources and carbon cycling processes within watersheds. While elevated ages in fluvially-transported organic matter are usually explained ...
Crustal magnetization and the subseafloor structure of the ASHES vent field, Axial Seamount, Juan de Fuca Ridge : implications for the investigation of hydrothermal sites
(John Wiley & Sons, 2016-06-24)
High-resolution geophysical data have been collected using the Autonomous Underwater Vehicle (AUV) Sentry over the ASHES (Axial Seamount Hydrothermal Emission Study) high-temperature (~348°C) vent field at Axial Seamount, ...
On the Southern Ocean CO2 uptake and the role of the biological carbon pump in the 21st century
(John Wiley & Sons, 2015-09-23)
We use a suite of eight ocean biogeochemical/ecological general circulation models from the Marine Ecosystem Model Intercomparison Project and Coupled Model Intercomparison Project Phase 5 archives to explore the relative ...
Nutrient enrichment induces dormancy and decreases diversity of active bacteria in salt marsh sediments
(Nature Publishing Group, 2016-09-26)
Microorganisms control key biogeochemical pathways, thus changes in microbial diversity, community structure and activity can affect ecosystem response to environmental drivers. Understanding factors that control the ...
Characterization of new microsatellite loci for population genetic studies in the Smooth Cauliflower Coral (Stylophora sp.)
A total of one hundred microsatellites loci were selected from the draft genome of Stylophora pistillata and evaluated in previously characterized samples of Stylophora cf pistillata from the Red Sea. 17 loci were amplified ...
Predicting Atlantic seasonal hurricane activity using outgoing longwave radiation over Africa
(John Wiley & Sons, 2016-07-08)
Seasonal hurricane activity is a function of the amount of initial disturbances (e.g., easterly waves) and the background environment in which they develop into tropical storms (i.e., the main development region). Focusing ...
