K. Megan McArthur

Katherine Megan McArthur (born August 30, 1971) is an American oceanographer, engineer, and NASA astronaut.

[2] At the Scripps Institution of Oceanography, McArthur conducted graduate research in nearshore underwater acoustic propagation and digital signal processing.

[2] Her research focused on determining geoacoustic models to describe very shallow water waveguides using measured transmission loss data in a genetic algorithm inversion technique.

While at Scripps, she participated in a range of in-water instrument testing, deployment, maintenance, and recovery, and collection of marine plants, animals, and sediment.

During this time, McArthur also volunteered at Birch Aquarium, conducting educational demonstrations for the public from inside a 70,000-gallon (265 m³) exhibit tank of the California Kelp Forest.

McArthur was the ascent and entry flight engineer and was the lead robotics crew member for the mission.
