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 1005 PMEL TPOS mission in the Pacific Ocean from 2018-10-03 to 2019-01-27 (NCEI Accession 0297635)

This file contains the real time data from the Saildrone core sensors for the Pacific Marine Environmental Laboratory (PMEL) TPOS 2018 Mission (Mission 2) to the central equatorial Pacific (0, 140W). These data have not been Quality Control (QC). This was the second of three missions funded by NOAA Office of Oceanic and Atmospheric Research (OAR)/CPO/GOMO and NOAA Office of Marine and Aviation Operations (OMAO) as a pilot study for the Tropical Pacific Observing System (TPOS)-2020 project. The drone were each equipped with full atmospheric and ocean core sensor suite, and an Acoustic Doppler Current Profiler (ADCP) (not included in this file). The vehicle was deployed out of Honolulu, HI on October 3, 2018. After sailing near a PMEL Carbon mooring in Kaneohe Bay, HI, the drone proceeded to the Tropical Atmosphere/Ocean (TAO) mooring at 9N, 140W. Navigation issues caused the mission to be aborted early (mid-December 2018), before further science tasks could be completed. Saildrone 1005 was recovered in Honolulu, HI on 01-27-2019
