Atmospheric Deposition of Nitrogen: Implications for Nutrient Over-enrichment of Coastal Waters
Atmospheric deposition of nitrogen (AD-N) is a significant source of nitrogen enrichment to nitrogen (N)limited estuarine and coastal waters downwind of anthropogenic emissions. Along the eastern U.S. coast and eastern Gulf of Mexico, AD-N currently accounts for 10% to over 40% of new N loading to estuaries. Extension of the regional acid deposition model (RADM) to coastal shelf waters indicate...
متن کاملImproved Atmospheric Correction for Aviris Spectra from Inland Waters
As part of an ongoing investigation of primary productivity in Mono Lake, a series of surveys were conducted at the lake coincident with AVIRIS acquisitions. These included sampling and spectroradiometric measurements with locations precisely georeferenced to AVIRIS pixel coordinates. Spectra were extracted from the AVIRIS images for the purpose of deriving predictive equations for calculation ...
متن کاملAtmospheric correction of SeaWiFS imagery for turbid coastal and inland waters.
The standard SeaWiFS atmospheric correction algorithm, designed for open ocean water, has been extended for use over turbid coastal and inland waters. Failure of the standard algorithm over turbid waters can be attributed to invalid assumptions of zero water-leaving radiance for the near-infrared bands at 765 and 865 nm. In the present study these assumptions are replaced by the assumptions of ...
متن کاملNutrient availability and phytoplankton nutrient limitation across a gradient of atmospheric nitrogen deposition.
Atmospheric nitrogen (N) deposition to lakes and watersheds has been increasing steadily due to various anthropogenic activities. Because such anthropogenic N is widely distributed, even lakes relatively removed from direct human disturbance are potentially impacted. However, the effects of increased atmospheric N deposition on lakes are not well documented. We examined phytoplankton biomass, t...
متن کاملDirect Patterning of Functional Materials via Atmospheric-Pressure Ion Deposition
Interest in thin films of functional materials has increased enormously in recent years because of the wide range of possible applications. Here we report an experimental setup we have termed Atmospheric-Pressure Ion Deposition (APID) as a novel technique that allows highly controllable and soft processing of various materials (e.g. polymers, bio molecules and inorganic materials) into thin and...
