Charles Eriksen is an oceanographer who designs and builds tools that help to increase our understanding of the oceans. He was instrumental in the development of the Seaglider, an autonomous long-range underwater glider that can be deployed for months at a time and traverse entire ocean basins. (One glider that Eriksen used still holds the record for time and distance traveled without the aid of current.) The Seaglider has been revolutionary in helping oceanographers around the world study upper ocean dynamics, allowing them to explore everything from water temperature to currents to harmful algal blooms. In addition to his work in the School of Oceanography, Eriksen is a Senior Fellow at the Joint Institute for the Study of the Atmosphere and Ocean (JISAO), a collaboration between UW and NOAA.
