The densest waters in the world ocean are
formed on the continental shelf areas around
Antarctica by ice formation and by the loss
of heat and water to the air. The Weddell Sea
(e.g., gordon, ...
Land Ice and Sea Level Rise:A Thirty-Year Perspective
Land Ice Sea Level Rise Thirty-Year Perspective
2015/7/9
The present-day assessment of contributions to sea level rise from glaciers and ice sheets depends to a large degree on new technologies that allow efficient and precise detection of change in otherwi...
Changes in the vertical distribution of primary production in response to land-based nitrogen loading
Terrestrial nitrogen load production

Watershed land use and river engineering drive wetland formation and loss in the Mississippi River birdfoot delta
Watershed land river engineering drive wetland ation loss the Mississippi River birdfoot delta
2014/4/2
The Mississippi River basin was developed for agriculture at an unprecedented scale and intensity within the last 200 yr. These changes favored erosion and sediment transport, which were subsequently ...
Unraveling the role of land use and microbial activity in shaping dissolved organic matter characteristics in stream ecosystems
role of land use microbial activity in shaping dissolved organic matter in stream ecosystems
2014/4/17
Surface water samples were collected from 43 streams distributed throughout watersheds of mixed land use in southern Ontario, Canada. Absorbance and fluorescence spectroscopy with parallel factor anal...
Nutrient inputs to the coastal ocean from submarine groundwater discharge in a groundwater-dominated system: Relation to land use (Kona coast, Hawaii, U.S.A.)
Nutrient inputs the coastal ocean submarine groundwater discharge in a groundwater-dominated system Relation to land use
2014/4/17
We evaluated the magnitude and composition (in terms of salinity,223Ra and224 Ra activity, and nutrient concentrations) of submarine groundwater discharge (SGD) fluxes at 11 sites on the Kona coast of...

Dust, winds, and waters. Bears and humans. All swirl together on this late summer afternoon in 2008 in Bear Head Lake State Park, Minnesota. A dry spell has turned dirt roads into arid trackways. Hint...
The Use of Land and Sea Based Wind Data in a Simple Circulation Model
South Atlantic Bight Simple Circulation Model Wind Data
2009/1/19
The use of land based wind data in nearshore oceanographic work is common, but these winds do not accurately reflect coastal oceanic winds. Ocean winds are often underestimated by a factor of 2 and di...
Preliminary studies on physical and chemical processes in the subsurface system in the land reclaimed from the sea
Land reclamation coastal process groundwater flow physiochemical reactions

Land reclamation has played a significant role in the urban development process in coastal areas in many countries. Over the last 20 years, land reclamation has gained much popularity especially along...
Vertical Variations of Tidal Currents in Shallow Land Fast Ice-Covered Regions
Vertical Variations Ice-Covered Regions Tidal Currents
2009/1/4
Arctic tidal currents with periods near the local inertial period are strongest and rotate clockwise at mid-depth, and decrease in amplitude towards the bottom and ice-cover, experiencing a change in ...
The Prediction of Nearshore Wind-induced Surface Currents from Wind Velocities Measured at Nearby Land Stations
Nearshore Wind-induced Surface Currents Wind Velocities Nearby Land Stations
