PO.DAAC is pleased to announce the dataset release of the S-MODE Pilot Field Campaign, which provides shipboard, in-situ, and airborne measurements from a variety of instruments and platforms during October 2021. S-MODE is funded by NASA through the Earth Venture Suborbital (EVS-3) program and is testing the hypothesis that submesoscale ocean dynamics, i.e. processes with scales of 1-10 km, make important contributions to vertical exchange of physical, chemical and biological variables in the upper ocean. This requires coordinated measurements from a novel combination of in-situ and remote sensing platforms and instruments, along with data analysis and modeling, to test the hypothesis. Datasets comprising this release include measurements of currents, conductivity, temperature, depth, nitrates, salinity, nutrients and meteorological data from a suite of shipboard instruments and autonomous surface vehicles; salinity, temperature, and currents from drifters and autonomous underwater vehicles; and surface winds, ocean currents, sea surface temperature, and visible imagery from airborne instrument platforms. This release contains data from the initial pilot field campaign. Additional documentation will be made available in the future upon release of the data from the IOP campaigns. More information on the project can be found at the S-MODE mission page.
