He also participated in renovation of the marine science exhibits at the Smithsonian National Museum of Natural History.
He doesn't seem to have a Ph.D. but I think that his commitment to the mission of the NOAA, and to the importance of real data, are clear. His 2015 promotion by Kathryn Sullivan, and support for his 2015 appointment by the NSF geosciences directorate (see #7, above) is also reassuring.
Here's an excerpt from his current NOAA bio:
