Situated on the east side of the Chesapeake Bay, 162 nautical miles above the Virginia Capes, Elk River is the western approach to the Chesapeake and Delaware Canal. The canal is one of the busiest waterways in the country. It connects the Chesapeake and Delaware Bays, servicing the ports of Baltimore, Wilmington, and Philadelphia. The U.S. Army Corps of Engineers regularly surveys the dredged channels in the approaches and in the canal, but they are not responsible for the remaining waters of the Elk River. The Elk River was last surveyed in the early 1900s, making depths on the nautical chart close to 100 years old! As a result, NOAA R/V Bay Hydro II was tasked to conduct a modern hydrographic survey of Elk River in Spring 2023.

NOAA hydrographic survey ships, navigation response teams, and contractors are preparing for the 2023 hydrographic survey season. The ships and survey vessels 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 considers other hydrographic and NOAA science priorities in determining where to survey and when. Visit our “living” ArcGIS StoryMap to find out more about our mapping projects and if a hydrographic vessel will be in your area this year!

The Columbia River and its tributaries comprise one of the largest river systems in North America, flowing from British Columbia, Canada and through the United States to its final destination, the Pacific Ocean. The river is used extensively for transporting various cargoes into and out of the United States including forest products, grain, containerized cargo and bulk products like salt and cement. Upstream of Portland, barge and recreational traffic navigate the river to Kennewick, Washington or Lewiston, Idaho on the Snake River. For the people that use this river for its resources, this traffic almost assuredly has some type of ecological impact.

Strategically placed around the country, NOAA’s navigation response teams―30-foot survey vessels with a three-person survey team―maintain emergency readiness while checking chart accuracy in changing ports and harbors. Navigation response teams work day-to-day in ports and harbors, collecting data to update the nation’s nautical charts. They measure depths, locate obstructions, report dangers to navigation, and update features for safe navigation. Whether there is a need to investigate wrecks, check for suspected shoals, conduct surveys for coastal management, or work with other federal agencies to support homeland security, Coast Survey’s navigation response teams have the expertise to get the job done safely and efficiently.

In 2022, NOAA and NOAA contractors will survey U.S. coastal waters and beyond, including multiple missions in the Great Lakes. As the volume, value and size of marine vessels in U.S. waters continues to grow, it is essential that NOAA increase the accuracy and frequency of surveys. A great amount of data on nautical charts of the Great Lakes is more than 50 years old, and only about 5 to 15 percent of the Great Lakes are mapped to modern standards using remote sensing methods such as light detection and ranging and sound navigation and ranging.

In 1959, following the International Geophysical Year of 1957-58, scientists from twelve nations conducting active research in Antarctica came together and signed the Antarctic Treaty. In the years following, 42 additional countries acceded to the treaty. The treaty preserves the entire continent and surrounding waters solely for purposes of peaceful scientific collaboration and bans resource extraction and military activity. McMurdo Station on Ross Island, operated by the United States through the United States Antarctic Program, a branch of the National Science Foundation (NSF), has emerged as the largest year-round station and primary logistics hub for the region. The first U.S. Operation Deep Freeze happened prior to and in support of the International Geophysical Year of 1957-58. Since then, Operation Deep Freeze has continued annually and has become the name for supply sealift missions to McMurdo, delivering fuel, food, and supplies to scientists in Antarctica.

Flushing Bay Channel Lighted Buoy 3 was struck by a tug and barge in late July, and was reported sunk immediately following the strike. The buoy marks the entrance to a channel frequented by commercial barge traffic, specifically, loaded fuel barges bound for LaGuardia International Airport. The Navigation Response Branch (NRB) was called upon in early August to assist United States Coast Guard (USCG) Sector New York in locating the sunken buoy in Flushing Bay, New York.

As the 2020 Atlantic hurricane season came to a close on November 30, NOAA’s Office of Coast Survey tallied a few numbers to see what the combined response effort of the navigation response teams, NOAA Ship Thomas Jefferson, and hydrographic survey contractor David Evans & Associates, Inc., looked like.

This week NOAA’s Office of Coast Survey concluded its hydrographic survey response following Hurricane Delta. At the immediate request of the U.S. Army Corps of Engineers (USACE), NOAA’s navigation response teams (NRTs) and NOAA Ship Thomas Jefferson surveyed areas within the Gulf Intracoastal Waterway (GIWW), Calcasieu Ship Channel, and the entrance to the channel. With lessons learned from the response to Hurricane Laura — the first major hurricane of the 2020 season and the first hurricane response during a pandemic — the teams and Thomas Jefferson successfully collected, processed, and delivered data to the USACE, identifying significant hazards to navigation and helping to ensure the timely reopening of waterways.

Hurricane Laura, the first major hurricane of the 2020 Atlantic Hurricane Season, made landfall over Louisiana in the early morning hours of Thursday, August 27. As a Category 4 storm and with maximum sustained winds reaching 150 miles per hour, it caused significant damage along the Gulf coasts of Louisiana and southeastern Texas. For NOAA’s Office of Coast Survey – whose job it is to identify dangers to navigation and help speed the reopening of ports and waterways following severe storms – this marked the first hydrographic survey response effort of the hurricane season.
