Uncrewed Surface Vehicles Arrive at the Equator to Monitor El Niño Development
The 120-day Tropical Pacific Observing System (TPOS) 2023 Saildrone Mission officially began on June 22, 2023, just after the official start of what experts suggest may be a strong El Niño. The three Saildrone, Inc. Explorer-class Uncrewed Surface Vehicles (USVs), launched from Honolulu, Hawai‘i, are now at the equator in the central Pacific (~155°W), about 1,300 miles south of the Hawaiian Islands.

The three Saildrone, Inc. uncrewed surface vehicles were launched from Hawai‘i and currently are at the equator in the central Pacific observing the developing El Niño. Sea Surface Temperature (SST) warmer than 90°F is shown in dark red. SST cooler than 70°F is shown in dark blue.
