The Armstrong Basin in the Gulf of Mexico, named for Joint Hydrographic Center NOAA co-director Andy Armstrong, is about 100 miles south of Galveston, Texas.

When Captain Andy Armstrong, the NOAA co-director of the , learned that a basin in the Gulf of Mexico would be named in his honor, he thought it was a mistake. 鈥淚 said, 鈥楢re you sure? There are lots of Armstrongs in the world,鈥欌 he says. 鈥淎t first I wondered if they thought I was dead, since seafloor features are often named for deceased individuals.鈥

Armstrong, who is assigned to the JHC as a civilian NOAA employee, is very much alive. In 1992, he was captain and chief hydrographer of the NOAA hydrographic ship Whiting when it mapped the seafloor bathymetry of the northwestern Gulf of Mexico that included his now eponymous basin. Compiling a more detailed seafloor map of the area recently, a team of oceanographers from Texas A&M University proposed that the basin, located just beyond the edge of the continental shelf about 180 kilometers (just over 100 miles) south of Galveston, Texas, be named after Armstrong.



鈥淲hile Andy's basin may be a large depression, his presence at CCOM/JHC has been anything but.听Andy has been a tremendous contributor to the success of the centers and a great supporter of state-of-the-art hydrography throughout the community,鈥 says CCOM director Larry Mayer, who is also Armstrong鈥檚 JHC co-director and director of the School of Marine Science and Ocean Engineering. 鈥淲e are very proud that his contributions have been recognized by this great honor.鈥

"While Andy's basin may be a large depression, his presence at CCOM/JHC has been anything but."听

The Armstrong Basin is a depression in the seafloor 10 by 30 kilometers in area and ranging in depth from 325 to 450 meters. While Armstrong recalls the seafloor of that area being interesting 鈥 鈥渋rregular with a number of bumps and basins鈥 鈥 he doesn鈥檛 have a particular memory of mapping 鈥渉is鈥 basin. That鈥檚 in part because unlike today鈥檚 mapping technology, hydrographers couldn鈥檛 鈥渟ee鈥 the seafloor in real time on ship-board computer screens.

鈥淵ou got a bunch of numbers back, then after the fact you could print up contour sheets,鈥 he says. 鈥淚t was different than the systems we have now, where you can perceive the sea floor as you go.鈥 Researchers at 91制片厂鈥檚 Center for Coastal and Ocean Mapping and the Joint Hydrographic Center Armstrong co-directs are at the forefront of the technology that brings bathymetric data to life with visualization.

Pleased to have a basin named after him, Armstrong notes that the Armstrong Basin is an honorary, not ownership, designation; any royalties from any resources would go to the federal government. 鈥淚t鈥檚 probably sitting on top of oil,鈥 he says.
