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.

In May of 2020, local geologists identified a steep, unstable slope that has the potential to become a tsunami-generating landslide in Barry Arm, a glacial fjord 60 miles east of Anchorage, Alaska. With documented cases of tsunami-generating landslides in Alaska including Lituya Bay in 1958 and Taan Fjord in 2015, this new hazard immediately caught the attention of state and federal partners who quickly joined forces to quantify the risk to those living and boating in Alaska’s Prince William Sound, specifically the communities of Whittier, Valdez, Cordova, Tatitlek, and Chenega.

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.

NOAA’s Office of Coast Survey, United States Coast Guard (USCG) Sector Honolulu, State of Hawaii Department of Transportation and United States Army Corps of Engineers (USACE) Honolulu Division established a memorandum of understanding (MOU) outlining each signatory’s area of responsibility in the event of a disaster in the Hawaii region. The intent of the MOU is to improve the efficiency and effectiveness of response efforts and speed the reopening of the ports and waterways following an emergency.

For more than 200 years, nautical cartographers have methodically charted our nation’s coastline, adding new features or hazards and updating meandering shorelines, all in an effort to aid safe navigation. However, occasions do arise that require immediate charting, particularly in response to national emergencies. Notable examples include charting the projected oil spill zone during the Deepwater Horizon oil spill disaster, as well as hazards during hurricane response efforts. Most recently, NOAA’s Office of Coast Survey was called upon to support the arrival of USNS Comfort to New York City.

The field of hydrography, like most sciences, is comprised of experts honing their craft, improving their tools, building upon the successes of previous years, and learning from their mistakes. Hydrographers typically accomplish this iterative process in the field, publishing papers, presenting at industry conferences, and often through discussions over the phone or via email. However, once a year, the NOAA hydrographic community — those who measure and describe the features of the seafloor to update nautical charts and support a variety of sciences — meets at the Field Procedures Workshop to not only share information, but have frank discussions about their challenges and the path forward in preparation for the upcoming hydrographic field season.

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.

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.

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.
