The 2019 Arctic Saildrone Mission was a joint effort between NOAA’s Pacific Marine Environmental Laboratory (PMEL) and Alaska Fisheries Science Center (AFSC), the NOAA/University of Washington Joint Institute for the Study of the Ocean and Atmosphere (Joint Institute for the Study of Atmosphere and Ocean [JISAO]), and the National Ocean Partnership Program (NOPP) Arctic MISST (Multi-sensor Improved Sea Surface Temperature) study.
Five of six vehicles (SD 1033, SD 1034, SD 1035, SD 1036, SD 1037) sailed into the Chukchi Sea: SD 1033 surveyed lines in Distributed Biological Observatories (DBO) 1-5; the remaining four ran transects in the Chukchi Sea approaching the southern sea ice edge to measure air-sea heat and momentum flux near sea ice.
The sixth vehicle (SD 1041) remained in the Bering Sea to measure fish acoustic backscatter and conduct focal follows of threatened fur seals for AFSC.
Each vehicle was equipped with the standard Saildrone sensor suite. Two vehicles (SD 1033, SD 1034) carried ASVCO2 systems to measure seawater pH, temperature, salinity, and partial pressure of carbon dioxide (pCO2). Five vehicles (SD 1033, SD 1034, SD 1035, SD 1036, SD 1037) were equipped with 300 kHz Acoustic Doppler Current Profilers (ADCPs) to measure near-surface currents. SD 1041 carried a Simrad WBT Mini and ES38-18/200-18C fisheries echo sounder.
During the mission, the vehicles experienced about two dozen encounters with free-floating sea ice. SD 1035 was caught in sea ice and rendered barely maneuverable with rudder damage on about August 24. Its mission ended early on September 10, after which it was towed into Point Barrow. The remaining vehicles sampled along Bering Sea transects and returned to Dutch Harbor on October 11 after sailing side-by-side for a few hours for an end-of-mission comparison.
Other supporting measurements made during this mission:
- The PMEL/WHOI/JISAO Arctic Heat Open Science Experiment dropped AXBTs July 16 – 22.
- USCGC Healy met SD 1033 on August 11 for a pCO2 cross-calibration.
- SD 1034 and SD 1035 sailed near the sites of periodic surfacings of Marine Robotic Vehicles (MRV) Air-Launched Autonomous Micro-Observer (ALAMO) float 9234.
- In August, SD 1036 followed a University of Washington Applied Physics Lab Seaglider in a bow-tie pattern near 73°N, 148°W.
This data set is hosted by NOAA PMEL and contains a subset of atmospheric and oceanographic variables from the mission.
