As the recipient of the 1983–1984 AGU Congressional Science Fellowship [Eos, September 6, 1983, p. 543] I have been asked to report on my midterm experiences.

Congressmen need and actively seek technical advice on legislative issues. As a scientist, one's point of view can have an impact on society as well as on one's discipline.
