The Southern Ocean Gas Exchange Experiment (SO GasEx) was a multi-agency field investigation that focused on quantifying gas transfer velocities within the marine air boundary layer. SO GasEx had one deployment during the austral fall of 2008 across the Southern Ocean. The NOAA Ronald. H Brown research vessel was equipped with several in situ and remote sensors to collect measurements of trace gases, aerosols, and ocean properties. Other water platforms such as drifting and moored buoys and an underwater surface vehicle (USV) were also deployed. SO GasEx was funded by NASA, NOAA, and NSF.
GasEx had two previous deployments in 1998 and 2001. Only the information for 2008 deployment is in this inventory since NASA only participated in that deployment.

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.
If instrument mode or detailed specification information is not available, can use this entry for spectrometers of various types. A spectrometer is an instrument that measures a range of a characteristic for a given substance or wavelength. There are many different types of spectrometers. Some examples are mass spectrometers, spectrophotometers, and magnetic radiation spectrometers.
The Multibeam Echo Sounder System (MBES) is an active sonar system that collects bathymetric measurements. MBES operates by transmitting a sound pulse and detecting objects in the water by the returning echoes. It measures the time and angle of each return to create a high-resolution three-dimensional (3D) surface model of the seafloor. High-frequency systems (100-1000 kHz) are typically used in shallow waters and can operate in waters as shallow as 1 m. Lower-frequency systems (10-70K kHz) can operate in deeper water depths (>10km deep) and can be installed on large research vessels.

Rain gauges are ground-based instruments that provide in situ measurements of liquid precipitation amounts over a set time. There are multiple types of rain gauges that each collect and record data differently such as the tipping bucket rain gauge and weighing precipitation gauge. Rain gauges can be deployed in various locations due to their relatively small size and easy set-up and are typically colocated with other precipitation instruments such as disdrometers to provide more details about precipitation being collected such as precipitation rate and size distribution.

The High-Performance Liquid Chromatograph (HPLC) is an in situ ground-based analyzer that is used to separate and identify components within a sample of air or mixture. It achieves this by injecting a liquid within the sample causing different flow rates for each component as they flow out of the column. As each component exits the column, their concentrations are measured at a high resolution. In Earth science research, HPLC is typically used to determine various trace species in the atmosphere such as formaldehyde, hydrogen peroxide, and volatile organic compounds (VOCs). HPLC is commonly used for laboratory analysis and ground-based measurements, but it can be used for airborne measurements as well.
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.
