NOAA sends Saildrones on mission to track El Niño

September 9, 2026 — A quartet of uncrewed surface vehicles are navigating 1,500 miles to the center of a historic El Niño gathering strength in the eastern Pacific, on a four-month mission to collect data on the warm-water impulse altering global weather patterns.

Two orange Saildrone Explorer 23′ USVs sailed Aug. 21 from Honolulu, carrying meteorological and oceanographic sensors and rendezvousing  with two other Saildrones on a 6,000-mile round-trip mission for NOAA’s Pacific Marine Environmental Laboratory (PMEL) according to a summary from the agency.

“A monumental El Niño is knocking at the door,” said Michael McPhaden, former PMEL senior scientist now working with NOAA’s Cooperative Institute for Climate, Ocean, and Ecosystem Studies (CICOES). “We’re going to take a closer look.”

The USVs will steer courses through the Tropical Pacific Observing System, a multi-national array of data-collecting moored surface buoys that provide continuous, real-time hourly tracking of surface winds, air temperature, humidity, and upper-ocean temperature down to 1,640’. Argo floats collect ocean profiles down to 1.24 miles every 10 days.

Distributed throughout the array are drifting buoys measuring sea surface temperature and currents. Overhead, satellites track the drifters and capture surface observations across wide areas.

NOAA to Deploy Saildrones for Climate Study

July 18, 2017 — During the next four months, NOAA scientists will deploy Saildrone unmanned ocean vehicles to hard-to-reach locales such as the Arctic and the tropical Pacific with the goal of better understanding of how ocean changes affect weather, climate, fisheries and marine mammals.

The Saildrone is wind and solar-powered research vehicle resembling a sailboat, capable of performing tasks at sea such as met ocean data collection, environmental monitoring and fish stock analysis, autonomously or under remote control. For NOAA, the vehicles will soon travel thousands of miles across the ocean, reaching some areas never before surveyed with such specialized technology.

In mid-July, scientists will send off the first unmanned, wind and solar-powered vehicles from Dutch Harbor, Alaska, with two sailing north through the Bering Strait into the Arctic Ocean and another transiting the Bering Sea. Traversing Alaska’s inhospitable waters, the remote-controlled vehicles will track melting ice, measure carbon dioxide in the ocean and count fish, seals and whales.

For the first time, the vehicles will journey through the Bering Strait into the Arctic with a newly adapted system to measure CO2 concentrations.

We want to understand how changes in the Arctic may affect large-scale climate and weather systems as well as ecosystems that support valuable fish stocks,” said Jessica Cross, an oceanographer at NOAA Research’s Pacific Marine Environmental Laboratory, who is using the unmanned system to study how the Arctic Ocean is absorbing carbon dioxide.

Unmanned vessels deployed for Alaska ocean research

June 6, 2016 — ANCHORAGE, Alaska — Researchers in the Bering Sea off Alaska’s west coast will get help this summer from drones, but not the kind that fly.

The National Oceanic and Atmospheric Administration and private researchers are gathering data on marine mammals, fish and ocean conditions from two “autonomous sailing vessels” built by Saildrone, an Alameda, California, company.

“Think of a 20-foot outrigger canoe with an airplane wing sticking up from the middle,” said Chris Sabine, director of NOAA’s Pacific Marine Environmental Lab, at a press teleconference Friday.

They hold great appeal for researchers because they’re far cheaper to operate than research ships and they can work in dangerous conditions of the North Pacific.

“Imagine the TV series, ‘Deadliest Catch,’ and you can imagine why we would like to remotely gather this information,” Sabine said from Seattle.

Operating by solar and wind power, the vessels can carry 200 pounds of instruments. Two were deployed last week from Dutch Harbor in the Aleutian Islands. Part of their payload will be acoustic gear that can pick up the sounds of North Pacific right whales, one on the most endangered animals on the planet.
