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...
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...

Oxygen isotopic fractionation and exchange during bacterial nitrite oxidation
Oxygen isotopic fractionation exchange bacterial nitrite oxidation
2014/4/17
We elucidate the controls on thed18 O values of microbially produced nitrate by tracking thed18O of nitrite and nitrate during bacterial nitrite oxidation, which is the final step of the nitrification...
Episodic circulation and exchange in a wave-driven coral reef and lagoon system
Episodic circulation and exchange in a wave-driven coral reef and lagoon system
2014/4/21
We examined the role of wave-driven circulation relative to wind and buoyancy forcing in a coral reef-lagoon system. Circulation measurements in Paopao Bay, Moorea, French Polynesia, during austral su...
Ice-ocean turbulent exchange in the Arctic summer measured by an autonomous underwater vehicle
Ice-ocean turbulent exchange Arctic summer measured autonomous underwater vehicle
2014/5/16
The first-ever observed horizontal profiles of summertime ice-ocean boundary layer fluxes were obtained using vertical water velocity, temperature, and salinity collected by an Autonomous Underwater V...
Efficacy of open-ocean ballast water exchange as a means of preventing invertebrate invasions between freshwater ports
open-ocean ballast water exchange preventing invertebrate invasion freshwater ports
2014/4/21
Ballast water is a major vector of nonindigenous species invasion globally. Mandatory ballast water exchange (BWE) was implemented for vessels carrying ballast water into the Great Lakes in 1993. Desp...
Circulation and turbulent exchange characteristics during the thermal bar in Lake Ontario
Circulation and turbulent exchange characteristics during the thermal bar in Lake Ontario
2014/5/19
We made observations from vertical moorings of thermistors and current meters in Lake Ontario to study the spring thermal bar circulation, its effect in inhibiting the horizontal mixing, and spatial a...
Oxygen dynamics in permeable sediments with wave-driven pore water exchange
Oxygen dynamics permeable sediments wave-driven pore water exchange
2014/5/14
The effects of advective pore water exchange driven by shallow water waves on the oxygen distribution in a permeable (k = 3.3 x 10-12 to 4.9 x 10-11 m2) natural sediment were studied with a planar oxy...
Seasonal variability of the effect of coral reefs on seawater CO2 and air-sea CO2 exchange
Seasonal variability coral reefs seawater CO2 air-sea CO2
2014/5/26
There are complex physical and biological processes controlling the exchange of carbon dioxide (CO2) between the ocean and atmosphere. In coral reef ecosystems, the balance of biological processes suc...
Quantifying groundwater discharge through fringing wetlands to estuaries: Seasonal variability, methods comparison, and implications for wetland-estuary exchange
Quantifying groundwater discharge fringing wetlands to estuaries Seasonal variability, methods comparison implications for wetland-estuary exchange
2014/6/9
Because groundwater discharge along coastal shorelines is often concentrated in zones inhabited by fringing wetlands, accurately estimating discharge is essential for understanding its effect on the f...
