Technological Innovations for Mid-Atlantic Cropping Systems
Greater projected demand for food, fuel, and fiber will require substantial increases in global agricultural production over the next three decades. Climate change is also forecasted to make weather events more extreme and variable. Efficiency will become more important as demand for food products …

Nitrogen and Phosphorus Management in the Mid-Atlantic
… phosphorus (P) in agricultural systems in the Mid-Atlantic is an important practice due to environmental and economic concerns. The objectives of the experiments reported in this dissertation were: (1) evaluate irrigation via evapotranspiration (ET) calculations for fresh market tomatoes grown …

Perceptions of hurricane hazards in the Mid-Atlantic region
The Mid-Atlantic region of the United States is susceptible to many tropical cyclone hazards such as storm surge, damaging winds, and flooding from heavy rainfall. Within the past fifteen years this region has experienced hurricanes Isabel in 2003 and Irene in 2011, as well as several tropical …

Climate extremes over the Mid-Atlantic states: a regional approach
… a late 20th century reference period to a mid-21st century business as usual (RCP8.5 and SRES A2) greenhouse gas-forcing scenario. Additionally, I used CMIP3 and CMIP5 data to compare regional climate model data to its global climate model boundary forcings, to see what added value the …

Challenges and Opportunities for Denitrifying Bioreactors in the Mid-Atlantic
… and expand their application beyond the Midwest to the agriculturally significant Mid-Atlantic region was investigated with a three-pronged approach: 1) a pilot study investigating controls on N removal, 2) a laboratory study investigating controls on emission of greenhouse gases nitrous …

MID-ATLANTIC RIDGE (12~16oN) BATHYMETRIC ANALYSIS BY EMPIRICAL MODE DECOMPOSITION
… an analysis of bathymetry at and proximal to the Mid-Atlantic Ridge (MAR) between 12°40’~16°15’N, 44.4~45.6°W, where are large bathymetric data set exist in a region where Oceanic Core Complexes have developed. It covers an area of about 15,600 square kilometers that contains at least seven …

Fish invasions in the Mid-Atlantic region of the United States
… assessed determinants of fish invasions in the Mid-Atlantic region of the United States. Data on nonnative fish distributions were obtained from the United States Geological Survey's Nonindigenous Aquatic Species Database (NASD). Nonnative fishes are introduced by a variety of pathways, and …

Abyssal mixing from bottom boundary effects in Mid-Atlantic Ridge flank canyons
… suggest that mixing in the flank canyons of the Mid-Atlantic Ridge generated when strong mean flows interact with the many sills and constrictions within the canyons may represent a dynamically important amount of abyssal mixing. The energy pathways and mechanisms of this mixing are much less …

Boundary layer dynamics and deep ocean mixing in Mid-Atlantic Ridge canyons
… hundreds of Grand-Canyon sized canyons that line mid-ocean ridges have particularly energetic mixing. To better understand the mechanisms by which rough topography translates into energetic currents and mixing, I studied diffusive boundary layers over varying topography using theoretical …

Hydrography and flow in the rift valley of the Mid-Atlantic Ridge
Slow-spreading mid-ocean ridges such as the Mid-Atlantic Ridge are characterized by deep axial rift valleys which are isolated from the water on the ridge flanks. Topographic effects therefore have a significant impact on the rift-valley hydrography and dynamics but little is known about the …

Studies of Benthic Macroinvertebrate Use for Biomonitoring of Mid-Atlantic Highland Streams
Research was conducted in three areas of water quality assessment. Long term ecological monitoring data from Shenandoah National Park (SNP) were analyzed and a protocol for data analysis was presented. Streams in SNP were found to be comparable to the best that can be found in the Blue Ridge …

Availability and Surface Runoff of Phosphorus from Compost Amended Mid-Atlantic Soils
The accumulation of P in soil from land-applied biosolids and manure increases the risk for P enrichment of agricultural runoff. Transport of these residuals to areas where P may be efficiently utilized is necessary to reduce the threat to water quality. Composting can improve biosolids and manure …

Radium isotopes as tracers of coastal circulation pathways in the Mid-Atlantic Bight
… of exchange between the shelf and slope in the Mid-Atlantic Bight were investigated using a combination of radiochemical tracer and hydrographic measurements. The motivation was to provide evidence of transport routes for shelfwater that could be important to the balance of shelf-slope exchange, …

SOIL ORGANIC CARBON IN MID-ATLANTIC REGION FOREST SOILS: STOCKS AND VERTICAL DISTRIBUTION
Soil contains the largest terrestrial pool of organic carbon (Boschi et al., 2018) and temperate forest soils have been a major sink for atmospheric carbon; however, determining the size of the soil organic carbon stock can be problematic. Sampling practices vary for sampling depth, and determining …
