CO2 perturbation experiments: similarities and differences between dissolved inorganic carbon and total alkalinity manipulations
Increasing atmospheric carbon dioxide (CO2) through human activities and invasion of anthropogenic CO2 into the surface ocean alters the seawater carbonate chemistry, increasing CO2 and bicarbonate (HCO − 3 ) at the expense of carbonate ion (CO 3 ) concentrations. This redistribution in the dissolved inorganic carbon (DIC) pool decreases pH and carbonate saturation state (). Several components...
متن کاملTotal Alkalinity of Surface Waters-A National Map
This map illustrates the regional patterns of mean annual alkalinity of surface water in the conterminous United States. As such, it affords a qualitative graphic overview to the sensitivity of surface waters to acidification. The map is based on data from approximately 2,500 streams and lakes and apparent spatial correlations between these data and macrowatershed characteristics, especially la...
متن کاملTotal carbon analysis may overestimate organic carbon content of fresh waters in the presence of high dissolved inorganic carbon
Automated carbon analyzers often are configured to provide estimates of both total organic carbon (TOC) and nonpurgeable organic carbon (NPOC). We show there can be an overestimation of total carbon in the presence of moderate to large quantities of dissolved inorganic carbon. This leads to overestimates of TOC, which is measured as the difference between total carbon and inorganic carbon. Wate...
متن کاملGlobal relationships of total alkalinity with salinity and temperature in surface waters of the world’s oceans
[1] A simple function of sea surface salinity (SSS) and temperature (SST) in the formAT = a + b (SSS 35) + c (SSS 35) + d (SST 20) + e (SST 20) fits surface total alkalinity (AT) data for each of five oceanographic regimes within an area-weighted uncertainty of ±8.1 mmol kg 1 (1s). Globally coherent surface AT data (n = 5,692) used to derive regional correlations of ATwith SSS and SSTwere colle...
متن کاملAlkalinity of the Mediterranean Sea
[1] Total alkalinity (AT) was measured during the Meteor 51/2 cruise, crossing the Mediterranean Sea from west to east. AT concentrations were high ( 2600 mmol kg ) and alkalinity-salinity-correlations had negative intercepts. These results are explained by evaporation coupled with high freshwater AT inputs into coastal areas. Salinity adjustment of AT revealed excess alkalinity throughout the ...
