HI Sea Fans!
I had the privilege of visiting the NOAA Gateway, an interactive exhibition about NOAA's science.
|"Hand of NOAA" by Ray Kaskey – this sculpture of a giant hand releasing seagulls to the ocean represents the agency’s mission of recording and protecting the environment.|
The Survey of the Coast was formed in 1807, renamed a few times and then became a part of NOAA in 1970.
Some items from early Coast Survey ships included china, a hat and epaulets from uniforms.
The Survey's mission was to provide accurate nautical charts (maps of the oceans), but now it includes most of the physical sciences including:
· hydrography (the science of the measurement and description and mapping of the surface waters of the earth with special reference to navigation),
· geodesy (the branch of maths dealing with the shape and area of the earth or large portions of it),
· astronomy (the study of celestial objects, space, and the physical universe as a whole),
· topography (detailed mapping or charting of the features of a relatively small area),
· oceanography (the study of the physical and biological properties and phenomena of the sea.),
· tide and current measurement and prediction,
· seismology (the study of earthquakes and related phenomena),
· national standards,
· photogrammetry (the use of photography in surveying and mapping to figure out measurements between objects.),
· and more.
I loved my visit, but I really enjoyed the videos from Ocean Today (http://oceantoday.noaa.gov/) and the Turtle Excluder Device (TED) which is a specialized device that allows a captured sea turtle to escape when caught in a fisherman's net.
In particular, sea turtles can be caught when bottom trawling is used by the commercial shrimp fishing industry. In order to catch shrimp, a fine meshed trawl net is needed.

Thanks so much to Peg Steffen for showing me around!
Have a great week, Sea Fans!
