BioSonics delivers Scientific Digital Echosounder for Antarctic Research.

Antarctic researchers visit BioSonics for orientation with new DT-X Digital Scientific Echosounder before leaving for Antarctic Cruise.

Researchers from the Palmer Long Term Environmental Research Project (PLER), Drs. Langdon B.Quetin and Robin Ross of the University of California, Santa Barbara, will be using the new BioSonics DT-X Digital Scientific Echosounder system for their ongoing project. Their work is designed to study the macrozooplanktonic community, particularly the Antarctic krill, in the upper 300 meters of the water column and the interactions between krill, its food source (phytoplankton), and one of its major predators (Adelie penguins)". Several other components of the Antarctic marine environment will also be examined using this exciting new equipment.

Drs. Quetin and Ross, along with Rob Edwards and Fred Stuart (of Raytheon Polar Services), visited BioSonics for familiarization and testing of the new system. The echosounder was purchased by Raytheon Polar Services specifically for this project.

PLER will be using the new DT-X system to replace the BioSonics Model 102 analog echosounder that has been used on this project since 1992. The system will be used for the annual long-term, large-scale research aboard the summer cruise this year. Next season it will also be used from an inflatible boat and incorporated into the more intensive, small-scale, nearshore environment studies at PLER Station.
