Increased thermal activity was detected to coincide with the onset of volcano inflation in the
seawater-filled caldera at Deception Island. This thermal activity was manifested in pulses of
high water temperature that coincided with ocean tide cycles. The seawater temperature
anomalies were detected by a thermometric sensor attached to the tide gauge (bottom
pressure sensor). This was installed where the seawater circulation and the locations of
known thermal anomalies, fumaroles and thermal springs, together favor the detection of …
