HARRNESS:A Framework for HAB Research and Monitoring in the United States for the Next Decade
HARRNESS HAB Research Monitoring United States Next Decade
2015/7/27
More than a decade ago, the U.S. approach to research on harmful algal blooms (HABs) was uncoordinated and modest in scale. Research groups were few and their work was piecemeal and constrained by sma...

Southeastern United States Deep-Water
2015/7/22
If nothing else, research in deep-sea environments teaches us how little we know about such important and productive habitats. The relatively recent discovery of hydrothermal-vent and cold-seep ecosys...
Patterns and Controls of Nutrient Concentrations in a Southeastern United States Tidal Creek
Nutrient Concentrations Southeastern United States
2015/7/16
Terrestrial inputs largely govern nutrient delivery to the coastal ocean, and subsequent processes transform these nutrients in the land-ocean transition zone. Here, we describe spatial and temporal p...
Holocene Sea Level Changes Along the United States' Atlantic Coast
Sea Level Changes the United States Atlantic Coast
2015/7/9
Reconstructions of Holocene relative sea level (RSL) have valuable applications in a number of topics within the Earth sciences, including calibrating and constraining geophysical models of Earth's rh...
Stable isotope estimates of evaporation : inflow and water residence time for lakes across the United States as a tool for national lake water quality assessments
inflow water residence
2014/11/28
We used water d2H and d18O from ca. 1000 lakes sampled in the 2007 U.S. Environmental Protection Agency’s
National Lakes Assessment (NLA) to assess two hydrological variables—evaporation as a percent...
The marine inorganic carbon system along the Gulf of Mexico and Atlantic coasts of the United States: Insights from a transregional coastal carbon study
The marine inorganic carbon system along Gulf of Mexico Atlantic coasts the United States a transregional coastal carbon study
2014/4/2
Distributions of total alkalinity (TA), dissolved inorganic carbon (DIC), and other parameters relevant to the marine inorganic carbon system were investigated in shelf and adjacent ocean waters durin...
The extent that natural lakes in the United States of America have been changed by cultural eutrophication
natural lakes the United States of America
2014/4/2
We used paleolimnological data for 240 lakes from the U.S. Environmental Protection Agency’s (USEPA)
2007 National Lakes Assessment to estimate the extent that natural lakes in the coterminous United...
The regional abundance and size distribution of lakes and reservoirs in the United States and implications for estimates of global lake extent
The regional abundance size distribution of lakes reservoirs in the United States implications for estimates global lake extent
2014/4/4
We analyzed complete geospatial data for the 3.5 million lakes and reservoirs larger than 0.001 km2, with a combined surface area of 131,000 km2, in the contiguous United States (excluding the Laurent...

Radiational Ocean Tides Along the Coasts of the United States
Radiational Ocean Tides United States
2009/3/9
A procedure has been developed for separating an analyzed S2 ocean tide amplitude and phase into gravitational and radiational components. Values obtained by applying the method to 11 one-year sets of...
Long Coastal-Trapped Waves off the West Coast of the United States, Summer 1973
Long Coastal-Trapped Waves United States West Coast
2009/3/7
Evidence for long coastal-trapped waves off the west coast of the United States is obtained from sea level, surface atmospheric pressure and wind records over a 1500 km alongshore separation for two m...
Ocean Currents along a Nearshore Frontal Zone on the Continental Shelf of the Southeastern United States
Ocean Currents Nearshore Frontal Zone Continental Shelf
2009/2/10
River and estuarine discharges mix to form a frontal zone along a 400 km length of the coast of the south-eastern United States. The frontal width extends from the coast outward 10–20 km. Two ships, a...
A Simple Method for Estimating Barotropic Tidal Currents on Continental Margins with Specific Application to the M2 Tide off the Atlantic and Pacific Coasts of the United States
Barotropic Tidal Currents United States Continental Margins
2009/2/7
Theory is developed to describe barotropic tidal currents on “smooth” continental shelves, that is, continental shelves with longshore scales much greater than the shelf width. Two models are consider...
On the Longshelf Structure and Dynamics of Subtidal Currents on the Eastern United States Continental Shelf
Middle Atlantic Bight Subtidal Currents Longshelf Structure Eastern United States Continental Shelf
2009/2/6
Strong correlations were observed among subtidal longshelf currents from the Middle Atlantic Bight (MAB) to the Georges Bank region, a distance spanning 615 km. The longshelf current consisted predomi...
Circulation on the Continental Shelf of the Southeastern United States. Part III：Modeling the Winter Wind-Driven Flow
South Atlantic Bight Continental Shelf Winter Wind-Driven Flow
2009/1/20
A vertically integrated two-dimensional model has been adapted for the study of the wind-driven flow on the South Atlantic Bight (SAB) shelf during the winter season. Wind data are used as an input to...
