During their time on the ice, the team will be able to communicate between themselves and the UK HQ, thanks to a 3-Way Person-to-Person communications system, developed especially for the Catlin Arctic Survey.

Direct communications from polar expeditions to back home up until now have been severely restricted, compared to communications from all other regions of the world. This is due to the extremely low data transmission rate offered by the only available network of communication satellites - the Iridium array.

Hi-tech sensors are worn around the wearer’s chest, to measure heart rate, breathing rate and volume. The Equivital Recorder/Transmitter continuously encrypts and transmits the wearer’s physiological data, which will in turn be sent to the survey vessel’s onboard processor before being transmitted back to the UK HQ.

The SeaCat system has been supplied by one of our Science Advisors, Professor Tim Stanton at the Naval Postgraduate School in Monterey, California. It consists of an ultra light weight winch system and a high resolution Conductivity Temperature Depth sensor package (CTD) made by Sea Bird Electronics.
