Application of Satellites to Chemical Oceanography

The article of record as published may be found at http://dx.doi.org/10.1021/ba-1985-0209.ch019Of the sensors now on satellites, none has been directly useful to chemical oceanography; however, concentrations of any chemical species that covary with temperature can be inferred from satellite measurements of temperature. This relationship is illustrated with satellite IR imagery off central California where large-scale changes in physical, chemical, and biological properties can occur and are frequently focused along frontal boundaries of upwelling systems. High inverse correlations of temperature with normally nonconservative plant nutrients, nitrate and phosphate, are used to calibrate satellite IR images as chemical maps yielding standard deviations of 14 and 7%, respectively. Chemical maps with satellite-derived maps of chlorophyll reveal a regional relationship between phytoplankton and chemical structure in the California coastal zone and the importance of chemical fronts as sites of chemical exchange and primary production

Seawater carbonate chemistry and calcification in the Bahama Bank, 1964-1965

Carbon dioxide is lost from the ocean by calcium carbonate precipitation (-p), photosynthesis (-b) and gas evasion at the sea surface (-g). Among the most active sites are warm shallow seas. In this paper seasonal studies on the Great Bahama Bank relate these processes in an equation which takes into account the indirect effects of advection (a), evaporation (e), and eddy diffusion (d). Calcium carbonate precipitation is very seasonal and accounts for about half of the total losses. The delta sum CO2/deltaCa ratio is always about 1.87 on the bank. A high summer carbonate loss is inversely correlated with summer increases of chlorinity and temperature suggesting that CaCO3 is precipitated inorganically or biogenic production of CaCO3 is regulated by these parameters or both
