Did you know that there are about 120 World War II era aircraft lying at the bottom of Lake Michigan? The Navy used these aircraft to train and certify pilots to take off and land from aircraft carriers during World War II. U.S. Naval operations along Lake Michigan, one of the Great Lakes, began in 1923. Between 1923 and 1942, operations expanded as the Navy built hangars, airfields, and landing strips across the village of Glenview, Illinois. By 1942, the Navy had a robust presence on the shores of Lake Michigan. With the U.S. entrance into World War II, the Navy needed a location to train carrier pilots. The growing threat of enemy vessels and mines along the Pacific and Atlantic coastlines and an already strong Naval presence in the area made Lake Michigan the safest location for carrier training.Continue reading “NOAA in the Great Lakes supports inter-agency search for WWII aircraft”
On November 15, 2019, the crew of NOAA Ship Rainier hosted a change of command in Valejo, California. Cmdr. Sam Greenaway accepted command of Rainier, relieving Capt. Ben Evans in a ceremony led by Capt. Michael Hopkins, commanding officer of NOAA’s Office of Marine and Aviation Operations (OMAO) Marine Operations Center-Pacific.Continue reading “Change of command for NOAA Ship Rainier”

At 8:29, on the morning of Friday, November 30, 2018, a magnitude 7.1 earthquake shook Anchorage, Alaska, for thirty stressful seconds. It was the largest earthquake in Anchorage since the Good Friday Quake of 1964, and brought Alaska’s most populated city to a standstill as residents evacuated buildings and came to terms with what they had just experienced.Continue reading “One year later – Coast Survey’s response to the Anchorage earthquake”

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.Continue reading “NOAA Ship Rainier returns to survey the Hawaiian coast, provides update on lava flow development”

During the month of October, NOAA Ship Thomas Jefferson integrated and operated a DriX, an Unmanned Surface Vessel (USV) created by the French technology company iXblue. The primary goal of the project was to test iXblue’s unique deployment and recovery solution specifically designed for Thomas Jefferson’s on board survey launch davit. Survey launches are limited to daylight operations and deployment and recovery are the most challenging operations the ship undertakes. Utilizing a DriX for continuous survey operations without having to recover and/or service it for up to four days straight would significantly increase the ship’s efficiency.Continue reading “NOAA Ship Thomas Jefferson tests innovative DriX unmanned surface vehicle”
While many are aware that hurricanes can inflict costly damage when they make landfall, tropical storms and depressions are not to be underestimated. Tropical Depression Imelda moved over the Texas coast in mid-September producing heavy rain and causing extensive flooding. Nine barges broke free from their mooring on the San Jacinto River and two of these barges hit the Interstate 10 bridge in Lynchburg, Texas. At the request of the U.S. Coast Guard Captain of the Port Houston-Galveston, NOAA’s Navigation Response Team (NRT)- Stennis was called in for rapid hydrographic survey response.Continue reading “NOAA responds to bridge damage near Houston following Tropical Depression Imelda”

If you have spent time on the water in Puget Sound, you have probably seen the large, distinct green and white vessels. These vessels move passengers, vehicles, and cargo across Puget Sound to the San Juan Islands and to Victoria, Canada, year round. They are a part of the Washington State Department of Transportation ferry system. The state has been operating ferries since 1951, and intended to run the ferry service until cross Sound bridges could be built. These bridges were never built, and the state continues to operate the ferries to this day. As of last July, there are 22 state-operated ferries on Puget Sound, with the largest vessel able to carry 2500 passengers and 202 vehicles.
One of these routes is a 30-minute transit from Coupeville, WA, to Port Townsend, WA, at the mouth of Puget Sound. This route carries roughly 820,000 passengers a year, and saves travelers from a five- hour drive around the Sound. n 2013 the Washington Department of Ecology and the Applied Physics Laboratory at the University of Washington installed instruments on board to measure the velocity of current at the entrance of the Sound. Due to the shallow depth of the ferry terminal at Coupeville, extreme (low) tidal conditions interrupt this ferry route up to three times a month.
NOAA’s Northwest and Pacific Islands Navigation Manager Crescent Moegling received a survey request from the Washington State Ferries in early summer of 2019 to survey this route. Following completion of a routine survey in Bellingham Bay, Navigation Response Team – Seattle (NRT-Seattle) along with augmenters Lt j.g. Joshua Fredrick, NOAA’s Center for Operational Oceanographic Products and Services, and Adrian Biesel, an intern at NOAA Office of Coast Survey’s Pacific Hydrographic Branch, traveled to Oak Harbor, Washington, on August 14. After safety and familiarization briefings, NRT-Seattle got underway from the Fort Casey State Park boat ramp daily to collect multibeam data. The team completed this request on August 19.
The density of the team’s data allows for confident detection of 1×1 meter objects on the seafloor. In addition to collecting information on the depth of the seafloor, the team also verified, investigated, and updated several features on the chart including but not limited to kelp beds, fog signals, and pier pilings.
Storms, particularly hurricanes, can be unpredictable. Therefore, NOAA’s hydrographic survey response teams that aid in the reopening of ports following storms, are designed to be flexible, proactive, and are on call 24/7 should the need arise to identify dangers to navigation.Continue reading “NOAA searches for dangers to navigation following Hurricane Dorian”

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.Continue reading “Hawaiian island surveys will update nautical charts and support habitat mapping efforts”

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.Continue reading “NOAA Ship Rainier successfully field tests autonomous hydrographic survey launch”
