Fluorescence Efficiency of Surface Seawater as a Function of Excitation and Emission Wavelength
Excitation and Emission Wavelength Surface Seawater
2015/8/19
Fluorescence of natural waters has often been employed in attempts to quantify dissolved chromophores. However, it has not always been recognized that the intensity of fluorescence obtained from a giv...
As one of few who have been involved in the equation of state of seawater over the last 40 years, I was invited to review some of the history behind its early development and also the more recent ther...
