NOAA Coast Survey’s new strategy supports charting mandates and broader seafloor mapping

This week, NOAA’s Office of Coast Survey released the Mapping U.S. Marine and Great Lakes Waters: Office of Coast Survey Contributions to a National Ocean Mapping Strategy. This report is part of NOAA’s ongoing commitment to meet core surveying and nautical charting mandates while supporting broader needs to fill gaps in seafloor mapping and environmental sciences.

Capturing scenes from hydrographic surveying

NOAA Ship Rainier kayak in Holkham Bay, Alaska

There are many benefits to working on a hydrographic survey project for NOAA’s Office of Coast Survey. Some would say having the opportunity to visit amazing landscapes, work with talented people, and collect important environmental data are just a few of them. Recently, Coast Survey’s Hydrographic Surveys Division hosted an internal photo contest inviting employees and contractors to submit images in the categories of Ships and Boats, Landscapes, People, and Data. On this Earth Day 2020, we thought we would share our contest winners with you.

NOAA ship readies for historic deployment to the Western Pacific to map the oceans

NOAA Ship Rainier in the Papahānaumokuākea Marine National Monument.

In three weeks, NOAA Ship Rainier will depart on the farthest journey of its 52-year history as it embarks on a multidisciplinary mapping trip to the Western Pacific. Rainier and a diverse team of scientists on board will map the waters from shore to almost 2000 meters deep around Guam and the Commonwealth of the Northern Mariana Islands including Saipan, Rota, and Tinian. The data and observations collected will support safe navigation, coral habitat and fisheries conservation, and storm surge and tsunamis modeling. The data will also be made available to those at the local level and contribute to the larger national and global initiatives regarding comprehensive seafloor mapping.

NOAA releases 2020 hydrographic survey season plans

NOAA 2020 Hydrographic Survey Season Story Map Cover

NOAA hydrographic survey ships and contractors are preparing for the 2020 hydrographic survey season. The ships collect bathymetric data (i.e. map the seafloor) to support nautical charting, modeling, and research, but also collect other environmental data to support a variety of ecosystem sciences. NOAA considers hydrographic survey requests from stakeholders such as marine pilots, local port authorities, the Coast Guard, and the boating community, and also consider other hydrographic  and NOAA science priorities in determining where to survey and when. Visit our “living” story map to find out more about our mapping projects and if a hydrographic vessel will be in your area this year!

NOAA Ship Rainier returns to survey the Hawaiian coast, provides update on lava flow development

Rainier collects multibeam sonar data along Puna Coast on the Big Island of Hawaii.

NOAA Ship Rainier’s four-decade tropical sonar silence is over and Hawaiian hydrography is back! The 2019 field season was productive, challenging, and geographically diverse. After starting the season with traditional hydrographic surveys in Alaska, Rainier was re-tasked to support science diving operations in the Papahānaumokuākea Marine National Monument that surrounds the Northwestern Hawaiian Islands. Though the primary purpose of this dispatch was to support coral reef research, the world’s most productive coastal hydrographic survey platform would have been remiss to forego this opportunity to ping new waters.

Hawaiian island surveys will update nautical charts and support habitat mapping efforts

For more than 50 years, NOAA Ship Rainier and its hydrographic survey launches have surveyed the Pacific seafloor. During this time, Rainier sailed thousands of miles, including the entire U.S. west coast, Alaska, and Hawaii. This year, Rainier expands on its traditional role of hydrographic survey and is supporting dive operations in the Northwest Hawaiian Islands and in the Papahānaumokuākea Marine National Monument. While Rainier is sailing these remote coral atolls, the survey launches — that are usually in its davits and deployed directly from the ship — are tasked to their own surveys around the islands of Maui, Moloka’i, and O’ahu.

NOAA Ship Rainier successfully field tests autonomous hydrographic survey launch

Autonomous survey launch.

By Lt. j.g. Airlie Picket

NOAA Ship Rainier field tested a new hydrographic survey platform this season. Last winter, one of the ship’s hydrographic survey launches was converted into a semi-autonomous vessel, allowing it to be operated remotely.  Hydrographic surveying is, by nature, dangerous. Autonomous systems have the potential to augment traditional surveying methods, improving efficiency and decreasing (or eliminating) risk to the surveyors themselves. As such, this technology is an exciting step toward fully-autonomous hydrographic survey systems.

NOAA releases 2019 hydrographic survey plans

NOAA Hydrographic Survey Projects 2019 story map cover

NOAA’s Office of Coast Survey is the nation’s nautical chartmaker, and maintains a suite of more than a thousand nautical charts. Coast Survey is responsible for charting U.S. waters and Great Lakes covering 3.4 million square nautical miles (SNM) of water and 95,000 miles of coastline.

NOAA’s hydrographic survey ships along with hydrographic contractor vessels, recently kicked off the 2019 hydrographic survey season. These surveys not only update the suite of nautical charts, but also help to maintain the safety of maritime commerce, recreational boaters, natural ecosystems, and much more. Operations are scheduled for maritime priority areas around the country and are outlined in Coast Survey’s “living” story map. Here is a list of where they are headed this year:

Seismic inter-agency collaborations on NOAA Ship Rainier

NOAA Ship Rainier spent September completing a multi-leg, joint collaboration project investigating deep offshore areas of the southern California coast. The U.S. Geological Survey (USGS) and Bureau of Ocean Energy Management (BOEM) partnered with NOAA to support a month-long mission to collect geophysical data along the outer continental shelf of California where the area in question features a number of different geologic structures and processes.
