SPURS-2 Field Campaign Datasets Released
[09-Apr-19] The Physical Oceanography Distributed Active Archive Center (PO.DAAC) is pleased to announce the availability of data from the NASA SPURS-2 field campaign. This initial release includes the first seven of what will ultimately be a total of twenty eight in-situ
datasets produced during SPURS-2 that will be archived/distributed by the PO.DAAC. Datasets comprising this release include: vertical profile data from lowered conductivity, temperature, depth (CTD), expendable bathythermograph (XBT) and ARGO profiling float instruments, water column current velocity profiles from shipborne Acoustic Doppler Current Profiler (ADCP), along-track multivariate sensor measurements from Saildrone, WAMOS wave radar data, and precipitation imagery data from the SEA-POL rain radar.
(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. 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. While SPURS-1 focused on the salinity maximum region of the sub-tropical N. Atlantic, SPURS-2 concentrated on the dynamic and seasonally variable, rainfall dominated region of the eastern tropical Pacific centered at 10N, 125W. 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
The SPURS-2 datasets are described, discoverable and accessible via the PO.DAAC data portal
