The sound of the Canada glacier streams and waterfalls dominated the soundscape of Lake Hoare. Here is one of several recordings I made while walking along the side of the glacier, listen for the percussive low tones:

I made this binaural recording while walking on Taylor glacier. It is about ten minutes long. Listen especially to the strange, almost electronic sound that occurs in the last minute. It is coming from moving water under the surface of the glacier. It surprised me so much that I had to bring Hassan over to listen to it too. The picture here is of the very place this sound came from:

The four of us: Hassan, Matt, Liz and I, lay on top of our equipment bags to keep them from flying away while the helicopter left us to work on the glacier. My favorite part of this recording is at the end – our expressions of excitement about getting to work. This is a binaural recording, so, as usual, headphones are recommended:
Before we left Taylor, the pilot and helo tech went through a checklist for takeoff. Recorded here through my helmet (keep those headphones on):

I spent my first day in the Dry Valleys on Taylor glacier with Hassan, Liz Bagshaw and Matt Hoffman. They were using an ice core drill to access the interior of cryoconite holes (cylindrical cavities in the ice filled with sediment, water, and air and covered with a clear ice lid) for Liz’s research and to measure the penetration of solar radiation at various depths of ice for Matt’s research. Pictured is Matt and the drill, and this is what it sounded like in action:

I spent the last four days following LTER Science Technician/Portland State University Research Assistant Hassan Basagic around to various meteorological monitoring (met station) sites in the Dry Valleys while camped out at Lake Hoare next to the Canada glacier. Besides being an expert on glacial ecosystems, Hassan is an electronics expert who provides support for several LTER projects.
This trip we traveled to three met station sites via helicopter where Hassan was checking and replacing equipment and downloading data: Taylor Glacier, Lake Bonney and Bonney Riegel. Here is a recording of part of our flight to Lake Bonney, with the voices of Hassan and the pilot:
