Congratulations to all involved with the 2016 Saildrone missions on receiving the Department of Commence Bronze Award and to Susie Snyder for receiving the NOAA Distinguished Career Award.
NOAA’s PMEL and Alaska Fisheries Science Center were awarded the Bronze Medal for “strengthening NMSF-OAR collaborations through the pioneering use of a Saildrone for next-generation ecosystem surveys in the Bering Sea”.
In 2016, the team successfully conducted the first ecosystem study using two Saildrones. The mission combined both physical and biological oceanography to seek out new ways to supplement traditional vessel-based research. The Saildrones each traveled almost 3,000 nautical miles in the 101 day mission testing innovative technologies, including a specially developed echo sounder and a modified whale acoustic hydrophone. Collectively, the oceanographic, meteorological, and fisheries measurements provided unique and groundbreaking insights to understanding the economically and culturally important ecosystem in the Bering Sea.
This was a collaborative mission between the NOAA’s Pacific Marine Environmental Lab, NOAA’s Alaska Fisheries Science Center, UW Joint Institute for the Study of the Atmosphere and Ocean, Saildrone Inc., Simrad AS/Kongsberg Maritime, Greeneridge Sciences Inc, and Wildlife Computers.

The DOC Bronze Award is the highest honor award granted by the Under Secretary of Commerce for Oceans and Atmosphere, which recognizes superior performance characterized by outstanding or significant contributions, which have increased the efficiency and effectiveness of NOAA.
Susie Snyder was also awarded The Distinguished Career Award for her “continued efforts in improving budgetary policies and procedures relating to memorandum of agreements and reimbursable funds throughout 30 years of service to NOAA”. This award honors contributions on a sustained basis — a body of work — rather than a single, defined accomplishment. This award also recognizes significant accomplishments across all NOAA program areas and functions that have resulted in long- term benefits to the bureau’s mission and strategic goals.

After 60 days in the Bering Sea, the Oculus Coastal Glider was successfully recovered by crew of the NOAA Ship Oscar Dyson on September 26, 2017. The glider successfully navigated 242.8 nautical miles, completed 3612 dives, and sampled salinity, temperature, dissolved oxygen, sunlight, and fluorescence at a frequency of approximately 3 dives per hour. The glider was tested in a region with a long history of shipboard and mooring observations that provide context for the Oculus glider's observations. Oculus glider measurements reveal detailed information in a known, important biogeographical transition that divides the ecosystems of the northern and southern Bering Sea shelf near St. Matthew Island. Measurements show unexpected ocean mixing in the water column near the island that may be due to internal waves. Data, sensor, and platform analysis is ongoing. Incorporating this higher resolution sampling into the Bering Sea observing network will improve our understanding of how these features affect the ecosystem.
The Oculus is a coastal glider engineered to work in the highly stratified, shallow depths of the Arctic. By using a rapid buoyancy system, the glider can change buoyancy states 20 times faster and achieve speeds three times faster than legacy gliders - allowing for a more efficient and adaptive Arctic survey, but transferable to a variety of markets.
This was the second field test for the Oculus coastal gliders. The first field test occurred early May 2017, also in the Bering Sea, with 387 dives completed near the M2 mooring site. For the second field test, the glider was deployed from the US Coast Gaurd Cutter Healy during the 2017 Arctic Shield mission.
The Oculus was developed at PMEL in partnership with the University of Washington's Joint Institute for the Study of the Atmosphere and Ocean and the University of Washington Seaglider Fabrication Lab.
On September 1, two saildrones launched from the Saildrone Inc. dock in Alameda, CA to begin their six-month, 8,000-nautical-mile, round-trip mission to the equator to improve the Tropical Pacific Observing System (TPOS). These saildrones are a component of a broader effort to rethink the Tropical Pacific Observing System (TPOS) that supports sub-seasonal to seasonal forecasting for the US. TPOS provides real-time data used by the US and partner nations to forecast weather and climate, including El Nino. The mission will be testing if this new, enhanced tool can collect a variety of measurements at a quality that matches research ships and proven mooring technology, Tropical Atmosphere Ocean (TAO) array. If this is the case, they may become a powerful tool to provide key observations for weather forecasts.
The saildrones are headed to the California Current Ecosystem (CCE) for a short test before taking part in a larger field study with NASA at the NASA SPURS study site in the eastern Tropical Pacific. The saildrones will perform an intercomparison with the Woods Hole Oceanographic Institution’s (WHOI) buoy and collect observational date in the study site. The saildrones will also do a calibration exercise with a research ship to ensure the accuracy and quality of the measurements that are being collected. This is particularly important to scientists when testing new sensors and technologies. Then the saildrones will travel south to the equator to do intercomparisons with the TAO moorings before heading back to Alameda, CA.
If the mission is successful, the improved data collection can help improve forecasts for El Nino’s and other weather phenomena that develop in the tropical Pacific and strongly impact North American weather patterns.

Over the next four months, NOAA scientists will launch unmanned ocean vehicles, called Saildrones, from the Arctic to the tropical Pacific Ocean to help better understand how changes in the ocean are affecting weather, climate, fisheries and marine mammals. The wind and solar-powered research vehicles that resemble a sailboat will travel thousands of miles across the ocean, reaching some areas never before surveyed with such specialized technology.
Earlier this week, PMEL scientists and Saildrone, Inc. sent off three saildrones from Dutch Harbor, Alaska. For the first time, two saildrones will sail north through the Bering Strait into the Arctic Ocean to study how the Arctic Ocean is absorbing carbon dioxide. A third unmanned vehicle will survey more than 3,100 nautical miles in the Bering Sea for walleye pollock, Northern fur seals that prey on them and the elusive North Pacific right whale. This work will build on research conducted during 2016, including a study of fur seal feeding rates. NOAA Fisheries Alaska Fisheries Science Center scientists will also attach video cameras to fur seals to record feeding and verify the species and sizes of fish that fur seals are eating.
In September, scientists will launch two more unmanned systems from Alameda, Calif., on a six-month, 8,000-nautical-mile, round-trip mission to the equator to improve the Tropical Pacific Observing System (TPOS). TPOS provides real-time data used by the U.S. and partner nations to forecast weather and climate, including El Nino. The unmanned sailing vehicles will take part in a larger field study with NASA, and visit mooring sites along the array of observing buoys.

May 16-June 2: The second summer field season for the Arctic Heat Open Science Experiment began with its first flight out of Kotzebue, Alaska. The research team, including Kevin Wood, are flying aboard a specially-outfitted NOAA Twin Otter aircraft to launch traditional atmospheric and oceanographic probes as well as the experimental Air-Launched Autonomous Micro-Observer (ALAMO) floats into the Chukchi Sea. After last year's field missions, two ALAMO floats made it through the winter and are currently profiling every 5 days. Check out the raw data for float 9085 and float 9076.
Arctic Heat is an open science experiment, publishing data generated by the project to further NOAA Science Missions with real-time data to facilitate timely observations for use in weather and sea-ice forecasts, to make data readily accessible for model and reanalysis assimilation, and to support ongoing research activities across disciplines.
Arctic Heat is a joint effort of NOAA Pacific Marine Environmental Laboratory (PMEL) Arctic Research, the Innovative Technology for Arctic Exploration (ITAE) program, the ALAMO development group at the Woods Hole Oceanographic Institution (WHOI), and the Joint Institute for the Study of the Atmosphere and Ocean (JISAO) at the University of Washington.
Last week, PMEL scientists attended the American Meteorological Society (AMS)’s Annual Meeting in Seattle, WA and the Alaska Marine Science Symposium (AMSS) in Anchorage, AK. Presentations covered research in the Bering Sea, data management and access, El Nino, sea ice, the Earth's energy imbalance, innovative technologies, and recent warming in the Pacific and others.
At AMSS, the Ecosystems and Fisheries-Oceanography Coordinated Investigations (EcoFOCI) group had multiple presentations and posters on the Bering Sea including topics on the recent marine heat wave in Alaska, linking annual oceanographic processes to contiguous ecological domains in the pacific Arctic, fish distributions, ecology, Saildrone and oceanography.
A wider range of topics were covered at AMS and included invited talks from Nick Bond, Chidong Zhang and Kevin Wood. Dr. Zhang spoke about the Dynamics of the Madden-Julian Oscillation; Kevin Wood presented the Old Weather Project using historical U.S. ship logbooks to collect and analyze historical climate data; and Nick Bond discussed the recent warming in the NE Pacific. The annual meeting is the world’s largest yearly gathering for the weather, water, and climate community and brings together atmospheric scientists, professionals, students, educators and research’s from around the world. AMS is the nation’s premier scientific and professional organization promoting and disseminating information about the atmospheric, oceanic, hydrologic sciences.

On September 3, after three months of collecting data in the Bering Sea, the two Saildrones have been safely recovered. The Saildrones each traveled almost 3000 nautical miles in 101 days. After arriving in Dutch Harbor, AK, the Saildrones were packed into a container and shipped to their home base in San Francisco, CA. Data from the tested technologies for fish and marine mammal acoustics are expected mid-September with preliminary analysis completed around the New Year.
This was a collaborative mission between the Pacific Marine Environmental Lab, Alaska Fisheries Science Center, Saildrone, Inc., Simrad AS/Kongsberg Maritime, Greeneridge Sciences, Inc, and Wildlife Computers.
Continue to follow the Saildrone on the Innovative Technology for Arctic Exploration page to learn more about upcoming events and preliminary results in the weeks and months to come.
In April, PMEL and JISAO scientists and engineers teamed up with Saildrone, Inc. to test two Saildrones in the harsh environment of the Bering Sea for the first time. The unmanned instruments sailed from Dutch Harbor, AK on April 22. They have traveled over 2,000 miles each since then, taking over 40 million measurements as they sail north following the ice retreat. With the Arctic environment changing rapidly, the success of these vehicles couldn’t come at a better time. The measurements taken across the eastern Bering Sea have the potential to provide a comprehensive picture of the changes that occur in the late spring environment when the ice is retreating.
PMEL’s Earth-Ocean Interactions program led by Oregon State University Cooperative Institute for Marine Resources Studies scientist, Dr. Bill Chadwick, has just launched a new blog aimed at analyzing and forecasting when the next eruption at Axial Seamount might occur. Axial Seamount is the most active submarine volcano in the NE Pacific. Located on the Juan de Fuca Ridge off the coast of Oregon, it was chosen as the site of the world's first underwater volcano observatory called NeMO and is now a node on the new Ocean Observatories Initiative (OOI) cabled observatory. Axial erupted most recently in 1998 and 2011.
Scientists from PMEL, Oregon State University, and University of North Carolina at Wilmington will be monitoring Axial closely. Watch the blog for forecast updates.
