Extensive in vivo measurements of exoprotease (leucine aminopeptidase, or
LAPase) activity of Antarctic marine bacterioplankton were made on the austral
autumn 1993 Long-Term Ecological Research (LTER) cruise of the RV Nathaniel B
Palmer.  The LTER grid consists of ten transect lines running approximately
perpendicular to the Antarctic Peninsula at 100 kilometer intervals, extending
from the coast to 200 kilometers offshore.  The lines are numbered 000 to 900
from south to north, and the stations are given numbers from 000 to 200 from
inshore to offshore (Waters and Smith 1992).
