    • Surface underway measurements of partial pressure of carbon dioxide (pCO2), sea surface temperature, sea surface salinity and other parameters from Autonomous Surface Vehicle (ASV) Saildrone 1068 PMEL TPOS mission in the Pacific Ocean from 2019-06-08 to 2020-01-07 (NCEI Accession 0302396)

    Metadata Updated: December 1, 2025

    This file contains near-real time data from the Saildrone core MetOcean sensors for the Pacific Marine Environmental Laboratory (PMEL) TPOS 2019 Mission ('Mission 3') to the central equatorial Pacific (0, 140W) for Saildrone 1068. These data have not been Quality Control (QC)'d. This was the third of three missions funded by NOAA/Oceanic and Atmospheric Research (OAR) and NOAA/Office of Marine and Aviation Operations (OMAO) as a pilot study for the Tropical Pacific Observing System (TPOS)-2020 project. PMEL TPOS 2019 Mission (aka Mission 3) had four Saildrones: SD1066, SD1067, SD1068 and SD1069. All were standard Gen 5 drones (but with copper paint), with standard wings, not the large wings used in Mission 2. All had an Acoustic Doppler Current Profiler (ADCP) (not included in this file) and the core MetOcean package. The core CTDs were an RBR in the flowthrough tunnel in the keel and a pumped SBE37 at the outflow of the flowthrough tunnel. Carbon system data (including its prawler Conductivity, Temperature, Depth (CTD) data) are served through a separate file.
