Beschreibung:
Using inorganic carbon measurements from an international survey effort in the 1990s and a tracer-based separation technique, we estimate a global oceanic anthropogenic carbon dioxide (CO2) sink for the period from 1800 to 1994 of 118 +/- 19 petagrams of carbon. The oceanic sink accounts for approximately 48% of the total fossil-fuel and cement-manufacturing emissions, implying that the terrestrial biosphere was a net source of CO2 to the atmosphere of about 39 +/- 28 petagrams of carbon for this period. The current fraction of total anthropogenic CO2 emissions stored in the ocean appears to be about one-third of the long-term potential.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sabine, Christopher L -- Feely, Richard A -- Gruber, Nicolas -- Key, Robert M -- Lee, Kitack -- Bullister, John L -- Wanninkhof, Rik -- Wong, C S -- Wallace, Douglas W R -- Tilbrook, Bronte -- Millero, Frank J -- Peng, Tsung-Hung -- Kozyr, Alexander -- Ono, Tsueno -- Rios, Aida F -- New York, N.Y. -- Science. 2004 Jul 16;305(5682):367-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Oceanic and Atmospheric Administration (NOAA) Pacific Marine Environmental Laboratory, 7600 Sand Point Way NE, Seattle, WA 98115, USA. chris.sabine@noaa.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15256665" target="_blank"〉PubMed〈/a〉
