The Arecibo Galaxy Environment Survey (AGES) is one of several HI surveys utilizing the new Arecibo L-band Feed Array (ALFA) fitted to the 305-m radio telescope at Arecibo.^a The survey is specifically designed to investigate various galactic environments to higher sensitivity, higher velocity resolution and higher spatial resolution than previous fully sampled, 21-cm multibeam surveys. The emphasis is on making detailed observations of nearby objects although the large system bandwidth (100MHz) will allow us to quantify the HI properties over a large instantaneous velocity range.
