The Inner Harbor Navigation Channel in New Orleans facilitates the transportation of tens of millions of tons of cargo each year. Since the channel was recently closed for repairs, a temporary Chandeleur Sound Alternate Route was established to ensure the flow of commerce between the western and eastern reaches of the Gulf Intracoastal Waterway. NOAA experts assisted with the alternate route development in various ways, collaborating with the U.S. Coast Guard, U.S. Army Corps of Engineers, and the maritime industry.

In a unique deployment of resources, last week NOAA Ship Fairweather split its scientific team and vessels to tackle two distinct projects in Alaska. Coast Survey physical scientist Katrina Wyllie and Lt.j.g. Bart Buesseler report on the multi-mission projects.
On August 9, NOAA Ship Fairweather departed Dutch Harbor, Alaska, for a FISHPAC project, led by Dr. Bob McConnaughey from NOAA’s Alaska Fisheries Science Center. This project’s primary mission is to statistically associate acoustic backscatter returns with the abundances of fish and crabs that frequent the Bering Sea seafloor. The science team accomplishes this with acoustic data from multibeam, single beam, and side scan sonars. Understanding the value of acoustic backscatter as a habitat-defining character will help scientists understand where fish live and the importance of different habitats. The acoustic data will also be used to correct for differences in the performance of research bottom trawls on different seafloor types, so that stock assessments and fishery management can be improved. To make sure the scientists understand what the acoustic data are showing, each day the ship will stop and collect physical bottom samples of the seafloor to see, touch, and interpret their findings. Further increasing the effectiveness of this mission, all of the multibeam bathymetry data acquired will directly support NOAA’s Office of Coast Survey as the data will be used to update soundings on the nautical charts for the eastern Bering Sea where the ship will be operating.

On this date in 1996, twenty years ago, the crew of NOAA Ship Rude completed her special mission and headed back to regular survey duties. Throughout the previous two weeks, Rude’s officers and crew were pivotal in finding the wreckage of – and helping to bring closure to – one of the worst aviation disasters in U.S. history.
From a 1996 report by then-Cmdr. Nick Perugini, NOAA’s Office of Coast Survey, we have this description:
“When TWA Flight 800 exploded out of the sky this summer, NOAA hydrographic survey vessel Rude began a dramatic journey which would test to the limit skills and resources of its officers and crew, and bring to national attention the agency’s hydrographic capabilities.
