Summary
Antarctic diving operations pose hypothermia risks. However, current practices and equipment show only minor rectal temperature drops, suggesting significant hypothermia is unlikely.
Area of Science:
- Physiology
- Marine Biology
- Polar Science
Background:
- Hypothermia is a significant risk during Antarctic diving operations.
- Assessing the impact of cold-water immersion on body temperature is crucial for diver safety.
Purpose of the Study:
- To measure rectal temperature changes in divers before and after Antarctic dives.
- To evaluate the risk of hypothermia in current Antarctic diving protocols.
Main Methods:
- Rectal temperature measurements were taken on two Australian National Antarctic Research Expedition (ANARE) expeditioners.
- Temperature data was collected prior to and following dives in Antarctic waters.
Main Results:
- Only minor decreases in rectal temperature were observed post-dive.
- The observed temperature changes suggest limited heat loss during dives with current methods.
Conclusions:
- Current Antarctic diving practices and equipment appear to mitigate the risk of significant hypothermia.
- Divers undertaking operations with existing protocols are unlikely to experience severe cold stress.
