Low frequency marine mammal calls were recorded on seven acoustic recording packages between March 2001 and February 2003 off the Western Antarctic Peninsula as a part of the U.S. SO GLOBEC program.  The following call types that were abundant in the data set will be described: blue whale D calls, minke whale downsweeps, and crabeater seal moans.  Several types of calls from unidentified sources will also be described, such as: 50 Hz up calls, pulsed song, and downswept song.  The seasonality of different call types will be presented and possible sources of unknown call types will be discussed.
