Summary of Database
The CLIVASH2k project focusses on understanding large scale climate variability modes in the Antarctic, sub-Antarctic, and Southern Hemisphere region over the past two millennia. The core aim of this database is to compile all publicly available sodium (NA+) and sulphate (SO42-) ice core records from the Antarctic region over the Common Era (0-2000CE). This collection builds upon previous Antarctica 2K compilations of δ18Oice ( Stenni et al (2017)), and snow accumulation ( Thomas et al., 2017). The database will be used to identify the role of atmospheric circulations (winds), and sea ice extent on climate, and surface mass variability in the Antarctic region over decadal to centennial time-scales.
Summary of Metadata
Metadata will be included for each record, describing the data site, collection information, and analytical details. Metadata categories are shown in the table below.
| Metadata category | Description |
| General | Key information about the study, including the Study Title (where, when, what |
| Site Information | the Site Name, latitude coordinates of the area, and elevation |
| Data Collection Information | Information specific to the dataset, including any core names, time ranges and resolution, as well as information about the core, such as core lengths, and accumulation rates and units |
| Analytical details | descriptions of the analytical methods, instruments used, and when the analysis occurred |
| Species info | list of species names |
| Funding Agency | funding details including agency name and grants supporting the project |
| 2k Specific fields | any fields that are cross-queriable with other PAGES products, such as Region location fields, Data Contributor names, working group involvement etc. |
How to Access Database
This database is currently in development, with a forecasted release in 2022. The data will primarily be stored on the UK Polar Data Centre data repository, with a possible secondary repository on The LiPDVerse.
