Interhemispheric Water Exchange in the Atlantic Ocean
Atlantic Ocean Interhemispheric Wate
2015/7/29
The tropical ocean spans 82 percent of Earth's equatorial circumference (Indonesian maritime continent included). Here, where the atmosphere's opposing Hadley Cells meet to produce the rainy Intertrop...
Investigations of Air-Sea Gas Exchange in the CoOP Coastal Air-Sea Chemical Exchange Project
Air-Sea Gas Exchange CoOP Coastal Air-Sea Chemical Exchange
2015/7/22
The exchange of CO2 and other gases across the ocean-air interface is an extremely important component in global climate dynamics, photosynthesis and respiration, and the absorption of anthropogenical...
Quantifying Benthic Exchange of Fine Sediment via Continuous,Noninvasive Measurements of Settling Velocity and Bed Erodibility
Fine Sediment Noninvasive Measurements Settling Velocity Bed Erodibility
2015/7/22
Benthic exchange of fine sediment has major implications for the structure and function of shelf and estuarine environments. Globally, the transport of particulate organic carbon from the land to the ...
Forcing and Dynamics of Seafloor-Water Column Exchange on a Broad Continental Shelf
Forcing and Dynamics Seafloor-Water Column Exchange Broad Continental Shelf
2015/7/22
Relict sediments of elevated permeability characterize the majority of continental shelves globally (Emery, 1968). In these settings, interactions between benthic boundary layer (BBL) flows and seabed...
Monitoring the Seafloor Using the Noninvasive Eddy Correlation Technique:Integrated Benthic Exchange Dynamics
Noninvasive Eddy Integrated Benthi Exchange Dynamics
2015/7/22
The eddy correlation technique has been used for 60 years in atmospheric boundary layer research to measure land-air exchanges of different constituents (e.g., Swinbank, 1951). Only recently, the tech...
Benefits of International Student Exchange and International Cooperation
International Student Exchange International Cooperation
2015/7/13
Since 2001, American and Taiwanese scientists have been conducting a series of six collaborative programs to explore ocean physics around Taiwan. Two of these programs, the Internal Waves in Straits E...
Stratification and horizontal exchange in Lake Victoria, East Africa
Lake Victoria East Africa
2014/11/28
We characterize stratification patterns over diel, seasonal, and annual time scales in inshore and offshore
regions of Lake Victoria, East Africa; determine conditions leading to horizontal exchanges...
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...

Salt marsh tidal exchange increases residence time of silica in estuaries
Salt marsh tidal exchange increases residence time of silica in estuaries
2014/7/10
We present flux measurements of dissolved silicon (DSi), biogenic Si (BSi), and dissolved inorganic nitrogen (DIN) and phosphorus (DIP) on a temperate salt marsh in Narragansett Bay, Rhode Island, ove...
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...
Exchange between suspended and sinking particles in the northwest Mediterranean as inferred from the organic composition of in situ pump and sediment trap samples
suspended sinking particles northwest Mediterranean as inferred from the organic
2014/4/16
The extent to which sinking particles disaggregate and exchange with surrounding material affects the
efficiency of particulate organic carbon export to the deep sea. In 2003 and 2005, we compared th...
Oxygen isotopic exchange and fractionation during bacterial ammonia oxidation

2014/4/16
We examined the oxygen isotopic systematics for ammonia oxidation, the first step in the regeneration of
nitrate from ammonium. In particular, oxygen isotopic fractionation and exchange with water we...
