Measurements were taken at 25 metres to characterize the temperature regime of the benthic community over the course of a year. Data were collected using a HOBO TidbiT v2 underwater data logger with an accuracy of ±0.2°C. The logger was mounted by scientific divers on the ground next to a large glass sponge (Anoxycalyx joubini). These high-resolution temperature recordings provide insights into the thermal environment shaping McMurdo Sound benthic ecosystems over the course of one year.166.636516-77.842056McMurdo Sound
