Sources of Anthropogenic 14c to the North Sea
The Sellafield nuclear fuel reprocessing plant on the northwest coast of England is the largest source of anthropogenic radiocarbon to the UK coastal environment. In a mid-1990s study of 14C distribution around the UK coast, the pattern of dilution with increasing distance from Sellafield appeared to be perturbed by anomalously high 14C activities in marine biota in the coastal environment of n...
متن کامل14C-glucose and 35S-metabolism of pig epiphysial cartilage and its variations after osteotomy.
On in vitro incubation of articular and epiphysial cartilage of the ulna of the domestic pig 70 to 80 per cent of [U-14C] glucose was metabolised to 14C-lactate, but cartilage of the epiphysial plate produced up to five times as much 14C-CO2 as articular cartilage, and the specific radioactivity of 14C(or 35S)-chondroitin 4(6)-sulphate isolated from epiphysial cartilage (following 35S-sulphate ...
متن کاملA mechanistic account of increasing seasonal variations in the rate of ocean uptake of anthropogenic carbon
A three-dimensional circulation model that includes a representation of anthropogenic carbon as a passive tracer is forced with climatological buoyancy and momentum fluxes. This simulation is then used to compute offline the anthropogenic 1pCO2 (defined as the difference between the atmospheric CO2 and its seawater partial pressure) trends over three decades between the years 1970 and 2000. It ...
متن کاملSeasonal, Latitudinal, and Secular Variations in Temperature Trend: Evidence for Influence of Anthropogenic Sulfate
Tropospheric aerosols increase the shortwave reflectivity of the Earth-atmosphere system both by scattering light directly, in the absence of clouds, and by enhancing cloud reflectivity. The radiative forcing of climate exerted by anthropogenic sulfate aerosols, derived mainly from SO2 emitted from fossil fuel combustion, is opposite that due to anthropogenic greenhouse gases and is estimated t...
متن کاملGeographic variations in anthropogenic drivers that influence the vulnerability and resilience of social-ecological systems.
Across the circumpolar North large disparities in the distribution of renewable and nonrenewable resources, human population density, capital investments, and basic residential and transportation infrastructure combine to create recognizable hotspots of recent and foreseeable change. Northern Fennoscandia exemplifies a relatively benign situation due to its current economic and political stabil...
