Radiocarbon in dissolved organic carbon of the South Pacific Ocean
Marine dissolved organic carbon (DOC) originates mainly from primary production using dissolved inorganic carbon (DIC) that has young C ages. Paradoxically, the C age of deep DOC ranges from 4000 to 6400 C years, indicating that a portion of DOC survives multiple, deep ocean mixing cycles. Here we show that C ages of DOC from the deep South Pacific are equal to those from the deep north central...
متن کاملNatural Radiocarbon Distribution in the Deep Ocean
We present for the first time objectively mapped natural radiocarbon (14C) abundance in the global deep ocean using mostly new measurements from the World Ocean Circulation Experiment (WOCE). Compared to earlier data from the Geochemical Ocean Sections Study, the new data number almost seven times more. Also, the WOCE data collected during the 1990s have sufficient spatial coverage to make obje...
متن کاملOcean acidification of the North Pacific Ocean
The addition of fossil fuel carbon dioxide to the atmosphere is rapidly changing seawater chemistry and the calcium carbonate saturation state of the world’s oceans as a result of the acidifying effects of CO2 on seawater. This acidification makes it more difficult for many marine organisms (e.g., corals, plankton, calcareous algae, and mollusks) to build skeletons, tests, and shells of calcium...
متن کاملOcean noise in the tropical and subtropical Pacific Ocean.
Ocean ambient noise is well studied in the North Pacific and North Atlantic but is poorly described for most of the worlds' oceans. Calibrated passive acoustic recordings were collected during 2009-2010 at seven locations in the central and western tropical and subtropical Pacific. Monthly and hourly mean power spectra (15-1000 Hz) were calculated in addition to their skewness, kurtosis, and pe...
متن کاملRadiocarbon as a thermocline proxy for the eastern equatorial Pacific
[1] An ocean model is used to test the idea that sea surface DC behaves as a thermocline proxy in the eastern equatorial Pacific. The ORCA2 model, which includes DC as a passive tracer, has been forced with reanalysis fluxes over 1948–1999, and the output is compared with a previously reported Galapagos DC record. The model reproduces the abrupt increase in the seasonally minimum DC in 1976/77 ...
