چکیده
[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 collected during the global carbon survey in the 1990s. Such regionspecific AT algorithms presented herein enable the estimation of the global distribution of surface AT when observations of SSS and SSTare available. Citation: Lee, K., L. T. Tong, F. J.

Evaluating Carbonate System Algorithms in a Nearshore System: Does Total Alkalinity Matter?
Ocean acidification is a threat to many marine organisms, especially those that use calcium carbonate to form their shells and skeletons. The ability to accurately measure the carbonate system is the first step in characterizing the drivers behind this threat. Due to logistical realities, regular carbonate system sampling is not possible in many nearshore ocean habitats, particularly in remote,...
متن کاملThe Alkalinity and Total Carbon Dioxide Concentration in the World Oceans*
The titration alkalinity and total carbon dioxide concentration data obtained during the GEOSECS Expeditions, 1972-1977, in the Atlantic, Pacific and Indian Oceans have been summarized. The oceans have been divided into seven oceanic regions, and the mean vertical distributions of the alkalinity and total CO2 concentration have been computed. In addition, the vertical distributions of these qua...

CTD (conductivity, temperature and depth) data collected in the coastal waters of Rudsar in summer 2008 were analyzed to identify the isothermal layers, thermocline depth and vertical structure of seawater properties. During the survey, probe was released into the seawater column down to 117 m depth. Results showed a vertical variation of temperature between 29°C at the sea surface and less tha...
