Measurements from the Sea2Space (Sea to Space Particle Investigation) project aboard the RV Falkor, supported by the Schmidt Ocean Institute, in the central and northeast Pacific.

Measurements taken during 1998 to 2000 in the Norwegian Sea.

Measurements made by the Akademik Kurchatov Russian research vessel in the Atlantic Ocean and Black Sea in 1988.

Measurements from the Barents Sea north of Russia made during 1998 by the Russian research vessel, the Akademik Sergey Vavilov.

This dataset contains water temperature, salinity, dissolved oxygen, and others. This data was collected by Seaglider 674 as part of the Southern Ocean Large Area Carbon Experiment (SOLACE) between December 12, 2020 and February 8, 2021. This program took place north of the subantarctic front south of Tasmania, near the Southern Ocean Time Series (SOTS) mooring (https://imos.org.au/facilities/deepwatermoorings/sots). The glider was outfitted with an unpumped Seabird CTD, an Aanderaa oxygen optode, and a WETLabs ECO puck, which allowed for the measurement of two wavelengths of optical backscatter as well as induced fluorescence. Data is gridded in depth at a resolution of 5 meters. Original profile (dive) data are also included. Salinity data is deemed unusable after January 18, 2021 as a result of biofouling of the sensor. This additionally impacts the density and spice measurements. Data are in NetCDF.

Seaglider is a buoyancy driven autonomous underwater vehicle (AUV) developed by scientists and engineers at the University of Washington's School of Oceanography and Applied Physics Laboratory. Seagliders are designed to glide from the ocean surface to a programmed depth and back while measuring temperature, salinity, depth-averaged current, and other quantities along a sawtooth trajectory through the water. Seaglider has entered wide use in scientific deployments. They are designed for missions in range of several thousand kilometers and durations of many months. Seagliders are commanded remotely and report their measurements in near real time via wireless telemetry.

The SPURS (Salinity Processes in the Upper Ocean Regional Study) project is a NASA-funded oceanographic process study and associated field program that aim to elucidate key mechanisms responsible for near-surface salinity variations in the oceans. The project is comprised of two field campaigns and a series of cruises in regions of the Atlantic and Pacific Oceans exhibiting salinity extremes. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber. Focused around a central mooring located near 10N,125W, the objective of SPURS-2 was to study the dynamics of the rainfall-dominated surface ocean at the western edge of the eastern Pacific fresh pool subject to high seasonal variability and strong zonal flows associated with the North Equatorial Current and Countercurrent. Underway surface profiling systems (USPS) are automated measurement systems coupled to a research vessels water intake and GPS systems. They provide continuous, along-track surface temperature and salinity measurements at depths of 2, 3 and 5 m using through-hull ports in the bow of the ship. Both SPURS-2 cruises had USPS and associated thermosalinograph (TSG) instrumentation, with measurements calibrated against onboard salinometers. There is one USPS netCDF containing the complete series for each of the 2 cruises.
