How ice shelf morphology controls basal melting
[1] The response of ice shelf basal melting to climate is a function of ocean temperature, circulation, and mixing in the open ocean and the coupling of this external forcing to the sub–ice shelf circulation. Because slope strongly influences the properties of buoyancy-driven flow near the ice shelf base, ice shelf morphology plays a critical role in linking external, subsurface heat sources to...
متن کاملcontrols on air pollution over a semi-enclosed basin, tehran: a synoptic climatological approach
in this study, a new array of meteorological elements and a synoptic climatologic classification to produce abaseline climate and to derive meteorological factors that are effective on air pollution in tehran, which is located in a semi-enclosed basin was developed. the data set includes daily sea-level pressure and 500mb geopotential height fields from ncep-ncar and tehran upper air sounding d...
متن کاملA synthesis of rates and controls on elemental mercury evasion in the Great Lakes Basin.
Rates of surface-air elemental mercury (Hg(0)) fluxes in the literature were synthesized for the Great Lakes Basin (GLB). For the majority of surfaces, fluxes were net positive (evasion). Digital land-cover data were combined with representative evasion rates and used to estimate annual Hg(0) evasion for the GLB (7.7 Mg/yr). This value is less than our estimate of total Hg deposition to the are...
متن کاملControls on erosion intensity in the Yangtze River basin tracked by U–Pb detrital zircon dating
a r t i c l e i n f o The Yangtze River dominates the drainage of eastern Asia, yet the processes that control erosion within the basin are obscure, making the interpretation of the detritus record difficult. In this study we used U–Pb dating of zircon grains from the modern main stream and major tributaries to identify the sources of sediment production, based on the diversity of zircon ages a...
متن کاملControls on Suspended Sediment Concentrations and Turbidity within a Reforested, Southern Appalachian Headwater Basin
Water quality data collected between 2007 and 2014 within the Allen Creek Watershed were used to: (1) determine the factors controlling the temporal variations in turbidity and suspended sediment concentration (SSC) within a representative, high-gradient headwater basin in the Southern Appalachians; and (2) assess the recovery of water quality following extensive logging operations during the e...
