Complementing the capabilities of mass spectrometry, several optical sensors are now being developed to provide information on low-volatility water constituents, such as heavy hydrocarbons, humic substances, and algal pigments. Both laser excitation and low-cost LED excitation are being utilized, and both wavelength-domain and time-domain data will eventually be used to increase the specificity of these techniques. These instruments are also designed with underwater deployment aboard an AUV in mind.
