Measurements of the Marine Reservoir Effect on Radiocarbon Ages in the Eastern Bering Sea
The marine reservoir effect is known to skew radiocarbon dating (marine samples appear “older” than terrestrial samples of equivalent age), but the magnitude of this effect is not the same in all locations. Carbon-14 age determinations from 23 paired samples of terrestrial and marine origin are presented for five areas around the northern and eastern Bering Sea. It appears statistically suitabl...
متن کاملMediterranean Sea surface radiocarbon reservoir age changes since the last glacial maximum.
Sea surface reservoir ages must be known to establish a common chronological framework for marine, continental, and cryospheric paleoproxies, and are crucial for understanding ocean-continent climatic relationships and the paleoventilation of the ocean. Radiocarbon dates of planktonic foraminifera and tephra contemporaneously deposited over Mediterranean marine and terrestrial regions reveal th...
متن کاملThe Mediterranean and Black Sea Fisheries at Risk from Overexploitation
The status of the Mediterranean and Black Sea fisheries was evaluated for the period 1970-2010 on a subarea basis, using various indicators including the temporal variability of total landings, the number of recorded stocks, the mean trophic level of the catch, the fishing-in-balance index and the catch-based method of stock classification. All indicators confirmed that the fisheries resources ...
متن کاملThe Mediterranean Sea
The Mediterranean was formed as a result of movements in both the Earth and sea beginning back in the second era, around two hundred and twenty million years ago. Violent upheavals have marked its history every since. Up until then, the continents had formed a single island known as Pangea. When they floated apart, a sea was formed. The Greeks later called this sea Tethys, after a goddess born ...
