Past Antarctic Ice Sheet Dynamics (PAIS)
PAIS supports continued development of the Antarctic Data Library System for Cooperative Research (SDLS). The SDLS now contains most processed data from marine multichannel seismic surveys that have been carried out around Antarctica. The SDLS provides open access worldwide to Antarctic multichannel seismic-reflection data collected by many countries to study the structure of Earth's crust of Antarctica. The new website that now provides open access to Antarctic multichannel seismic-reflection data online is http://sdls.ogs.trieste.it/ -- Operated and administered at the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS) by Nigel Wardell.
While PAIS does not directly support other data archiving infrastructure, it will maximize the effectiveness of it’s limited budget by encouraging responsible archiving of data and samples to established data centres and repositories. Among these databases the most relevant to the data to be generated by PAIS will be:
PANGAEA the data Publisher for Earth & Environmental Science- http://www.pangaea.de/
This data repository holds all data from the two past ANDRILL drilling seasons will receive data from the future Coulman High drilling (Table 1), as well as a wealth of data from marine sediment cores from the Southern Ocean. The IODP data bases and core repositories http://www.iodp.org/access-data-and-samples also hold all cores and data obtained during past Antarctic margin and Southern Ocean drilling by the Deep Sea Drilling Project (DSDP), the Ocean Drilling Program (ODP) and the Integrated Ocean Drilling Program (IODP). A data portal that will become relevant for PAIS continental slope-to abyss transects will be the IPEV IMAGES Programme Sub-Antarctic and Antarctic portal - http://gcmd.gsfc.nasa.gov/KeywordSearch/Home.do?Portal=amd_fr, which contains data from both marine and ice core records. Other databases included NOAA NCDC/NSIDC, and national programmes metadata systems.
For data management within PAIS, a Data Coordinator will serve on the PAIS Steering Committee. A PAIS sub-committee on Data Management, guided by the Data Coordinator, will 1) engage in cross-linkage activities and the facilitation of cross-SRP data sharing via web-based utilities, and 2) maintain ongoing communication with national funding programmes, currently expanding their emphasis on responsible and cost-effective data management, protection, archiving, and sharing.
The RAISED reconstructions of timeslices of Antarctic Ice Sheet Deglaciation are available as Supplementary Information in each of the constituent papers (see: http://www.sciencedirect.com/science/journal/02773791/100/supp/C )
A set of plottable datasets of grounding line positions are available as Supplementary material to the overview paper by Bentley et al (see: http://www.sciencedirect.com/science/article/pii/S0277379114002546 )
