Declines shellfish species rocky seashores climate-driven changes
2020/10/30
The waters of the Gulf of Maine are warming faster than oceans almost anywhere on Earth. As the level of carbon dioxide rises in the atmosphere, it's absorbed by the sea, causing pH levels to fall. Oc...
Whole-Genome Positive Selection and Habitat-Driven Evolution in a Shallow and a Deep-Sea Urchin
positive selection dN/dS
2015/12/11
Comparisons of genomic sequence between divergent species can provide insight into the action of natural
selection across many distinct classes of proteins. Here, we examine the extent of positive se...
Internal Wave-Driven Surface Currents From HF Radar
Internal Wave-Driven Surface Currents HF Radar
2015/8/10
Surface current observations from high-frequency (HF) radar have revealed that not only are the low-frequency and tidal currents resolved by the measurement, higher-frequency motions are also containe...
Two important aspects of tidal currents are (1) their temporal coherence and (2) their constancy (over centuries). The first rigorous evaluation of an Ocean Surface Current Radar (OSCR) system exploit...
Supply-Side Ecology and the Response of Zooplankton to Climate-Driven Changes in North Atlantic Ocean Circulation
Response of Zooplankton Supply-Side Ecology
2015/7/29
Recent findings from oceanographic field studies conducted on both sides of the North Atlantic have dramatically altered our view of how zooplankton populations respond to climate-driven changes in oc...
A Laboratory Demonstration of Coriolis Effects on Wind-Driven Ocean Currents
Wind-Driven Ocean Currents Coriolis Effects
2015/7/20
Here we study the mechanism by which the wind drives ocean circulation. We induce cyclonic and anticyclonic circulation by blowing air over the surface of a rotating tank of water using fans co-rotati...
Eutrophication-Driven Deoxygenation in the Coastal Ocean
Eutrophication-Driven Deoxygenation Coastal Ocean
2015/7/17
Human activities, especially increased nutrient loads that set in motion a cascading chain of events related to eutrophication, accelerate development of hypoxia (lower oxygen concentration) in many a...
Buoyancy-Driven Flows
Buoyancy-Driven Flows
2015/7/15
Buoyancy forces, and their interplay with pressure, inertia, and rotation, represent a key ingredient in a wide range of oceanic and atmospheric flow processes. They strongly influence global ocean ci...
Pore-water exchange driven by tidal pumping causes alkalinity export in two intertidal inlets
intertidal inlets idal pumping
2014/10/16
Carbon (C) and alkalinity export from two adjacent intertidal inlets with different terrestrial inputs was
investigated. One inlet receives a small creek from an agriculturally dominated catchment, l...
Threshold-driven shifts in two copepod species: Testing ecological theory with observational data
Threshold-driven shifts two copepod species Testing ecological theory observational data
2014/4/2
We used an observed abrupt shift in the dominance pattern of two coexisting copepod species in Müggelsee, a shallow eutrophic lake in Germany, to investigate mechanisms leading to this shift, by embed...
Effects of a wind-driven cross-shelf large river plume on biological production and CO2 uptake on the Gulf of Mexico during spring
biological production Mexico during spring
2014/4/2
The plume of Mississippi and Atchafalaya River system (MARS) is normally confined to the continental shelf
and extends westward. During March 2010, while weather in North America was dominated by unu...
The “salt wedge pump”: Convection-driven pore-water exchange as a source of dissolved organic and inorganic carbon and nitrogen to an estuary
salt wedge pump Convection-driven pore-water exchange source of dissolved organic inorganic carbon nitrogen to an estuary
2014/4/4
Hypoxia and anoxia in coastal waters have typically been explained by the respiration of sinking organic matter associated with nutrient over-enrichment and phytoplankton blooms. Here, we assess wheth...

Hypoxia and anoxia in coastal waters have typically been explained by the respiration of sinking organic matter associated with nutrient over-enrichment and phytoplankton blooms. Here, we assess wheth...
Evaluating the effect of wind-driven patchiness on trophic interactions between zooplankton and phytoplankton
wind-driven patchiness trophic interactions zooplankton and phytoplankton
2014/4/17
We measured spatial patterns of zooplankton and chlorophyll concentration (a proxy for phytoplankton) with continuous sensors along horizontal transects that were repeatedly sampled (n = 150) under va...
