either as a result of military operations, industrial discharges, medical releases, or nuclear accidents. This has resulted in their widespread distribution, cycling across the sea and uptake by biota, both locally (in the vicinity of discharge points) ...
Natural and anthropogenic radionuclides are ubiquitous in the marine biosphere. They are used to study a suite of environmental processes, including those related to marine food webs, yet they also potentially negatively impact marine biota and humans. The goal of this lecture is to provide upper ...
Scientists around the world, from any of the IAEA’s 172 member states, can use the IAEA’sMarine Radioactivity Information System(MARIS), which provides access to a comprehensive library of samples taken over the last 60 years and covering more than 100 different radionuclides found in the ocea...

The measurement of the temperature gradient and thermal conductivity in the sediments beneath the floor of the North Atlantic Ocean is described. Measurements were made at five stations. The mean heat flow and conductivity were found to ... Bullard,E. - 《Proceedings of the Royal Society of Lon...
摘要: The distribution of radioactivity discharged from Sellafield in Cumbria (north-west England) has been measured against a background of nuclear weapon fallout, with the object of determining the pathways and transfer mechanisms between various environmental media....
that all the radioactive elements are concentrated in the upper part of the earth’s crust. This hypothesis was partially confirmed in the 1970’s with the measurement of the concentrations of U and Th (10–6percent) in rock samples of the earth’s mantle taken from beneath the ocean ...
Just as the depth of the crust varies, so does its temperature. The upper crust withstands the ambient temperature of the atmosphere or ocean—hot in arid deserts and freezing in ocean trenches. Near the Moho, the temperature of the crust ranges from200° Celsius (392° Fahrenheit) to 400...
