In June, 1999, a portion of the Georges Bank fishing grounds (Closed Area II) that had been closed to protect depleted groundfish stocks was opened to US commercial sea scallopers to harvest sea scallop beds that had grown substantially. Vessels that participated in the exemption fishery were each allowed a maximum of three trips in Closed Area II. A trip was limited to 10,000 pounds of scallop...

Abstract We analyze the evolution of undeformed Middle to Late Pleistocene deposits Es Codolar (Southern Eivissa, Western Mediterranean). The outcrop records a succession characterized by alternation aeolian, colluvial and alluvial fan palaeosols that result in complex stratigraphic architecture. In this area, aeolian beds, are exposed along sea-cliffs for almost 500 m, allowing detailed descri...

A better understanding of expected future cyclonic activity, especially in winter the Mediterranean basin, is essential developing scientifically based adaptation and mitigation methods to study extreme precipitation wind anomalies. The aim this was analyze changes activity Mediterranean–Black Sea region, as part North Atlantic–European sector, at three 15 year periods: beginning, middle, end 2...

We predict the decadal change in position of three American Samoa mangroves from analysis of a time series of remotely sensed imagery, a geographic information system, tide gauge data, and projections for change in sea-level relative to the mangrove surface. Accurate predictions of changes to coastal ecosystem boundaries, including in response to projected relative sea-level rise, enable advanc...

The sea ice motion, area export, and deformation of the Ross Sea ice cover are examined with satellite passive microwave and RADARSAT observations. The record of high-resolution synthetic aperture radar (SAR) data, from 1998 and 2000, allows the estimation of the variability of ice deformation at the small scale ( 10 km) and to assess the quality of the longer record of passive microwave ice mo...

demonstration of the geomorphological factors in setting the legal regime of the caspian seaintroduction:the caspian sea is the largest water basin which enclosed by land within eurasia continent. the caspian sea is unique in many reasons: the large deposits of oil and gas, valuable fishery resources; including 90% of the world’s stock of sturgeon, important transportation routes; connecting th...

The carbon dioxide (CO2) content of the atmosphere has varied cyclically between approximately 180 and approximately 280 parts per million by volume over the past 800,000 years, closely coupled with temperature and sea level. For earlier periods in Earth's history, the partial pressure of CO2 (pCO2) is much less certain, and the relation between pCO2 and climate remains poorly constrained. We u...

during february of 2005 the north of iran witnessed the development and activity of a variety of severe meteorological systems accompanied with unusual heavy precipitation, mostly snow and hail. the rate and amount of snow in the northern coastal region was so heavy that it made a new record for that region with a report of more than 3m of snow in rasht, a city located in that area. also the da...

different ecologic factors influence on forming, development and sustaining of the plant communities, among which physiographic variables are the most important ones. the aim of this study was to identify forest types and effect of physiographical factors such as sea level height, slope and aspect of the site on quantitative characteristics of forest types in 2nd district of vaz forest with are...

In order to clarify the sedimentary development law under Cambrian Ordovician regional stratigraphic framework in Tadong area, and lay a theoretical foundation for further oil gas exploration study area. The distribution, characteristics evolution of main facies belts are studied by means drilling core observation, cast thin section identification, logging curve feature analysis, seismic profil...
