The EXport Processes in the Ocean from RemoTe Sensing (EXPORTS) is a NASA campaign to develop a predictive understanding of changes in ocean color and how they will impact the Earth’s carbon cycle. EXPORTS has completed two deployments across the North Pacific in 2018 and across the North Atlantic in 2021. Measurements were taken using autonomous underwater vehicles (AUVs), buoys, and shipborne instruments. EXPORTS was funded by the Ocean Biology and Biogeochemistry Program.
Conductivity, Temperature, and Depth (CTD) sensors are in situ instrument packages that are 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 deployed on a vessel, CTD sensors are typically attached to a rosette and then lowered to the seafloor to measure water properties. CTD sensors have a typical sampling rate of 30 Hz and can collect precise measurements for a specific water depth depending on the researcher's needs.

The Acoustic Doppler Current Profiler (ADCP) is an in situ acoustic sensor used to measure ocean currents. ADCP uses the Doppler effect to detect sound waves to provide measurements of the speed and direction of currents throughout the water column. ADCP can easily be mounted on different water platforms such as ships, buoys, and autonomous underwater vehicles (AUVs). It also can be deployed on the seafloor to provide profile measurements of ocean currents.
Gravimeters are passive sensors that measure the strength of Earth’s gravitational field. These measurements are used for determining density variations in rocks, oil and mineral prospecting, the monitoring of glacier changes, and the study of volcanic activity. Gravimeters can be used for airborne and ground-based operations.

The PAR (Photosynthetically Active Radiation) Sensor reports the Photosynthetic Photon Flux Density (PPFD), which corresponds to micromoles of photons per meter squared per second (μmol m-2 s-1). This is the power of electromagnetic radiation in the spectral range that is used by plants for photosynthesis (400–700 nm). It features a waterproof sensor head and can be used to measure PPFD from sunlight and electric light sources. This sensor is ideal for experiments investigating photosynthesis and primary productivity and can be used in many agricultural and environmental science applications.
