Saildrone Launch Begins Test to Improve West Coast Fisheries Surveys

June 28, 2018

Saildrones join NOAA’s West Coast fleet for experimental fisheries surveys.

Technicians prepare the first two Saildrones for launch

Technicians prepare the first two Saildrones for launch from Neah Bay, Washington.

Two autonomous Saildrones launched from Neah Bay, Wash., Tuesday on a summer-long partnership between The next link/button will exit from NWFSC web siteSaildrone Inc., NOAA Fisheries and Fisheries and Oceans Canada (DFO) to find out whether the wind and solar-powered vehicles can improve the efficiency and accuracy of fisheries surveys off the West Coast.

The two Saildrones will first head to the northern end of Vancouver Island and will then turn south, following a series of transects along the Coast south to San Francisco. Two other Saildrones will join the project fleet next week from Alameda, Calif., following transects from San Francisco south to the Southern California Bight.

They will gather acoustic data on Pacific hake (whiting) and pelagic species such as sardines, anchovy and mackerel that make up many of the West Coast’s most important commercial fisheries. Fishermen unloaded 558 million pounds of hake worth about $47 million in ports such as Astoria, Ore., and Westport, Wash., in 2016.

The NOAA ship Reuben Lasker will also follow the transects and gather similar acoustic data for comparison. The Lasker is specially equipped with advanced echosounders for accurately surveying fish populations.

A fifth Saildrone launching from Alameda in August will test its value for conducting focused fisheries surveys, such gathering data in near-shore areas that large NOAA research ships cannot safely reach. The fifth vehicle will focus particularly on historically important areas for fisheries, such as Monterey Bay and off the San Francisco Bay Area.

“This partnership is putting some of the most important new marine technology to work for the West Coast,” said Toby Garfield, Acting Deputy Director of NOAA Fisheries’ Southwest Fisheries Science Center in La Jolla, Calif., and part of the team directing the fifth Saildrone. “The more complete and accurate data we have, the better decisions our fisheries managers can make in real terms of catch levels and seasons.”

The first two Saildrones left Neah Bay about 1 p.m. Tuesday. The vehicles were operating normally, scientists said, but must travel to Canadian waters before they begin collecting data on their transects heading south. The Saildrone team extended its thanks to the The next link/button will exit from NWFSC web siteMakah Tribe, which authorized the launch from its marina in Neah Bay.

The northernmost surveys are particularly important for hake, a deep-water fish that supports an international fishery that the United States and Canada manage jointly under the Pacific Whiting Treaty. DFO scientists are assisting in management of the mission.

Please follow the progress of the West Coast Saildrone fisheries mission on the blog “Unmanned! Saildrone Expedition 2018.”

NOAA Fisheries' Alaska Fisheries Science Center has been testing Saildrone technology, along with NOAA Research's Pacific Marine Environmental Laboratory in Alaska for the past three years to gather oceanographic data, acoustic data on endangered North Pacific right whales, information on walleye pollock, and for prey surveys within the foraging range of a declining population of northern fur seals. This year, the focus in Alaska will be on studying abundance and distribution of Arctic cod in the Chukchi Sea.

The launch of Saildrones along the West Coast demonstrates NOAA Fisheries’ continued commitment to embrace new technologies to maximize efficiencies and advance its mission.
