Welcome to the British Antarctic Survey's Geophysics Data Portal. This portal aims to make visualisation and download of geophysical data held by BAS more accessible to the academic community.
The mapping interface allows for the selection of data by cruise or geopgraphical region. You can select a region by using ctrl-mouse drag to define a region, or enter it manually. Using shift-click will zoom to a defined region.
Under the Antarctic Treaty of 1961 (http://www.scar.org/treaty/) data collected south of 60ºS are to be made freely available to enable the global scientific community to gain a greater understanding of the importance of Antarctica and its surrounding seas in the Earth System, through international co-operation.
In line with NERC policy, data will be made available to others (under suitable constraints, and at no more than the direct costs involved in supplying the data) for further bona fide research only. The Intellectual Property Rights to the data are not transferred. For commercial use of data it is NERC policy to charge at a rate which reflects the value of the data and the cost it has incurred in data acquisition, custody and retrieval.
By downloading or consulting data from this website, the visitor acknowledges that he/she agrees with the NERC data policy (http://www.nerc.ac.uk/research/sites/data/policy.asp), and agrees to the following:
