PolarGAP is an ambitious international mission to capture new and critical data about the Earth’s global gravity field. 

Innovative radar systems and Lidar technologies will also be deployed from Twin Otter aircraft to fill the ‘data gap’ in

measurements of surface elevation over the South Pole region south of 83.5°.

Two earth observing satellite missions (GOCE and CryoSat 2) mounted by the European Space Agency (ESA) revolutionised

scientists’ ability to ‘map’ the Earth’s global gravity field and monitor how Earth’s ice fields are responding to global

change.  However, because GOCE’s orbit did not cross the Poles there is a data gap at the South Pole.

The PolarGAP project will collect new gravity data and combine them with datasets from other Antarctic missions to build

the first accurately constrained global gravity model. This is essential as global gravity data provide unique

information on mass distribution and transport in the Earth System, linked to processes and changes in the Solid Earth,

hydrology, cryosphere, oceans and atmosphere. Key applications of gravity data include geodetic studies (levelling and

mapping), navigation (GPS/GLONASS) and satellite orbit planning.
