ADMAP was launched in 1995 to compile and integrate into a digital database all exisiting near-surface and satellite mangetic anomaly data collected in Antarctica and surrounding oceans south of 60 degrees. Since then, the ADMAP has been updating the databases with additional surveys as well as investigating the areas of special interest.
A series of databases have been made available:
This map was generated using ADMAP near-surface compilation and Orsted satellite total intensity anomaly data (Kim, 2002) at 700 km. The surface gaps were augmented by the algorithm in Kim et al. (2004) for the wavelengths larger than 400 km. Details about this map was described in Kim et al.(2004).
The grid data for this map in ASCII format as a compressed ZIP file is available here (4.3 Mb).
This map was generated using ADMAP near-surface compilation and Magsat satellite total intensity anomaly data at 400 km. The surface gaps were augmented by equivalent point diple source technique for the wavelengths larger than 400 km.
The grid data (5 km interval) for this map in ASCII format is available here as a zipped file (14.9 Mb).
The image file for this map in CorelDraw version is available here as a zipped file (14.4 Mb).
This map was generated using ADMAP near-surface compilation data collected by all ADMAP WG and finalized by Dr. Golynsky (Golynsky et al., 2002).
The grid data (5 km interval) for this map in ASCII version is available here as a zipped file (9.4 Mb).
The image file for this map in CorelDraw version is available here as a zipped file (21.3 Mb).
The databases are also available at the ADMAP website.
Science in Antarctica relies on a consistent geographic framework. SCAR encourages the community to share its information to make maximum use of all data; to develop and operate mechanisms to facilitate the collection, storage, retrieval and dissemination of data and information for the common good; and to ensure that these mechanisms are effective. One of the major outcomes of combining a consistent geographic framework with available data are resulting maps with the best available information.
The Standing Committee on Antarctic Geographic Information (SCAGI) manages and enhances the geographic framework for Antarctic scientific research, operations, environmental management, and tourism.

SCAR promotes free and unrestricted access to Antarctic data and information by promoting open and accessible archiving practices. SCAR aims to be a portal to data repositories of Antarctic scientific data and information.
The SCAR data Policy is described in
SCAR report No 39
SCAR's Standing Committee on Antarctic Data Management (SCADM) facilitates co-operation between scientists and nations with regard to scientific data, and advises on the development of the Antarctic Data Directory System.

establishes and supports a distributed system of interoperable databases, giving easy access through a single internet portal to a set of resources relevant to research, conservation and management pertaining to Antarctic biodiversity (also known as ANTABIF, the Antarctic Biodiversity Information Facility)
an online database of terrestrial species that captures all recorded species observations and their locations from the Antarctic and subantarctic including information on taxonomy, collections and observations, bioregions, and alien species
a high quality dataset for the purposes of mapping plankton biodiversity: monitoring and development of models at seasonal, inter-annual, decadal, and spatially local and global scales; and providing core plankton data for ecosystem models
a database contains monthly mean surface and upper air climatological data derived from the in-situ meteorological observations made at Antarctic stations with long-term records, including temperature, surface pressure, wind speed/direction and geopotential height

In December 2016, a new Antarctic map, “Bathymetry and Geological Setting of the Drake Passage”, was released. This SCAR product represented an international collaborative effort coordinated by the Spanish Geological Survey (IGME) and the British Antarctic Survey (BAS), working together with the Korea Polar Research Institute (KOPRI), the Alfred Wegener Institute (AWI) and the United States Antarctic Program (USAP).
The map covers an area of 1470000 km2 between parallels 52ºS and 63ºS and between meridians 70ºW and 50ºW, where the high resolution bathymetric data covers more than 70% of the region with a 200 m cell resolution of the sea floor topography. The data were collected over the last 25 years on more than one hundred oceanographic cruises onboard six different Antarctic research vessels. This initiative is part of SCAR's IBCSO (International Bathymetric Chart of the Southern Ocean) Expert Group, which recognises the importance of regional data compilations in Antarctic areas of particular scientific interest. The map has been published by the BAS and the IGME, with support from SCAR through the Geosciences Group.
The Drake Passage is an oceanic gateway of approximately 850 km width located between South America and the Antarctic Peninsula that connects the southeastern Pacific and the southwestern Atlantic oceans and influences mantle flow, oceanographic water mass exchanges and migrations of biota. This gateway opened within the framework of the geological evolution of the Scotia Arc; a tectonic setting which developed since the early Oligocene and includes the Scotia and Sandwich plates. It is bounded to the north by the North Scotia Ridge, to the south by the South Scotia Ridge, to the west by the Shackleton Fracture Zone, and to the east by the South Sandwich Trench. The Scotia Sea contains several active and extinct spreading ridges that led to the opening of the Drake Passage. Several continental banks and oceanic basins are located in Scotia Sea, most notably in its southern part.
The geodynamic evolution of the region, seismic activity and tectonic data suggest a complex evolution of the Drake Passage such that the Shackleton Fracture Zone began as an oceanic ridge-to-ridge transform fault with strike-slip motion along most of its length, and subsequently became a transpressive transcurrent fault zone as it is at present. The Shackleton Fracture Zone, which occupies a central position in the Drake Passage, intersects two extinct spreading centres – the West Scotia Ridge (extinct 6.4 Ma ago) and the Phoenix-Antarctic Ridge (extinct 3 Ma ago), and is an intra-oceanic ridge which rises several hundreds to thousands of metres above the surrounding seafloor. Uplift of the Shackleton Fracture Zone in the last 8 Myr has formed a barrier for oceanic bottom currents.
The opening of the main southern oceanic gateways, Drake Passage and the Tasmanian gateway, separating South America and Australia from Antarctica respectively, permitted the present pattern of global ocean circulation to be established. This allowed extensive exchange of water between the main ocean basins and led to the development of the Antarctic Circumpolar Current, which contributed to the thermal isolation of Antarctica, was partially responsible for global cooling at the Eocene-Oligocene boundary and played an important role in middle Miocene cooling.
