Marine Invertebrates of McMurdo Sound

For two field seasons, the SCUBA diving activities of this project routinely involved photographing these animals in all the dive locations as a way to document what we observed as the dominant organisms at each site.

Ice diving is very strenuous for humans, and often the constraints of managing the work on a dive, monitoring air reserves, tracking proximity to the dive hole, and the 50 minute exposure to subfreezing temperatures limits a divers ability to "catalog" observations that are not essential to the current dive plan. The photographs archived here have provided the project's dive team with the ability to "debrief" following a dive and more or less reenact the dive by moving through the photograph images.
