Chilean scientists added Antarctica to the Pole to Pole project, which seeks to compile data on Atlantic and Pacific ocean temperature variations throughout the Western Hemisphere.
Between January and March, specialists placed a series of biometric sensors to record water temperatures surrounding the frozen continent.
This initiative joined an international effort of more than 30 researchers from different countries of the Americas to combine data from specific areas to create a hemisphere-wide database.
Scientist Erasmo Macaya placed eight sensors on the rocky coast of Fildes Peninsula on King George Island off the Antarctic Peninsula.
The small sensors were either inserted into mollusc shells or shaped like limpets, then placed in both sunny and shady locations to compare temperatures.

Dr Macaya told EFE the temperature data could be retrieved remotely using mobile technology, unlike other types of sensors.
"To download data of this kind, scientists usually have to extract the sensor and connect it to a computer with a specific reader .. .this technology is comparatively much friendlier," she said.
"It facilitates access to the information and avoids losses of what has been recorded. All that is needed is to have the application on the cellphone and take it to the device."
This project - which already includes the United States, Mexico, Brazil, Ecuador, Costa Rica, Argentina, Colombia, Canada and the Virgin Islands - will for the first time provide Pole to Pole with data from Antarctic waters.
These sensors will be removed in February 2020, when enough data will have been collected to begin work together with the other countries involved in the hemispheric project.
"The idea is that the information compiled will help nations have the right guidelines for the conservation of biodiversity," Dr Macaya said.
