Turbidity sensors are in situ water quality sensors that measure the cloudiness, or turbidity, of a liquid caused by suspended particles. Turbidity sensors are nephelometers that emit light and detect the amount of light scattered by particles within the water sample. These sensors are used for assessing sediment levels and pollution in rivers and lakes, and monitoring the water quality of drinking water and industrial processes.

Fluorometers are water-based sensors that measure patterns of fluorescence. They provide measurements of chlorophyll-a fluorescence, optical backscatter, and colored dissolved organic matter (CDOM) in seawater. They are typical used to asses chlorophyll concentrations to determine phytoplankton concentrations in the ocean. Fluorometers can be deployed on research vessels, buoys, autonomous underwater vehicles, and other water-based platforms.

Generic-Chemistry Related Sensors (Gen-Chemistry) refers to non-specific instruments on a platform used for atmospheric chemistry measurements. These are typically in situ analyzers that measure various chemical compounds such as trace gases, halocarbons, volatile organic compounds, nitrates, aerosols, and other chemical species. Measurements can include mixing ratio, composition, particle size, optical properties, and particle size distribution.

Conductivity, Temperature, and Depth (CTD) sensors are in situ instruments used to measure water depth, pressure, salinity, temperature, and density in the ocean. CTD sensors can be deployed on various water-based platforms such as autonomous underwater vehicles (AUVs), buoys, gliders, or research vessels. When mounted on a vessel, CTD sensors are usually attached to a rosette and then lowered to the seafloor to record water properties. These sensors typically sample at 30 Hz and can provide accurate measurements at specific water depths according to the researcher's needs.
