Load viewstate

A viewstate functions as a bookmark that saves your currently selected filters and other user interface settings. Viewstates are public and can be viewed by anyone with the link, so can be used for sharing ideas. Please note that they may not persist between interface versions, and so should not be used in publications. We are working on an alternative system for providing permanent identifiers for filter results.

Your viewstate is now saved with the key:

How to get started

SEAD contains a vast amount of data, you sort through and view parts of this data by applying filters to it. As you apply your filters a data visualization in either tabular or cartographic format will be displayed on the right. If you have not applied any filters, nothing will be shown, since showing all the data in the database would not be beneficial.

Start by selecting at least one filter through the filter menu in the top left corner. You then need to make a selection in this filter in order to activate the rendering of a result view. For a list based filter, simply click on the rows you like to apply as filters. For a diagram/span filter, select the span you would like to view by sliding the two handles at the bottom of the filter. For a cartographic filter, create a polygon selecting an area of interesting by holding the CTRL/CMD-key and left clicking.

You may also find it beneficial to activate the tutorial mode, which you will find in the settings menu. This will show tooltips at certain points to help explain things.

The Strategic Environmental Archeology Database

SEAD is a national research infrastructure for Swedish archaeological science and an international database for environmental archaeology and Quaternary science data. It is hosted by the Environmental Archaeology Lab (MAL) and Humlab at Umeå University, Sweden.

As well as providing sustainable data storage, SEAD facilitates the analysis, visualisation and extraction of data on past climates, environments and human impacts, and forms part of an international network of research infrastructure for archaeology, Quaternary palaeoecology and biodiversity studies. Our mission is to provide easy access to data and online tools to aid interdisciplinary, international research which goes beyond the original purpose of the data.

SEAD includes online access to the BugsCEP palaeoentomology database. Further digitization and development is ongoing in partnership with the National laboratory for wood anatomy and dendrochronology at Lund University, the Archaeological Research Lab, Stockholm University, SKEA (Stilborg Keramikanalys), and other organisations in Sweden. Legacy data are included from The Laboratory for Ceramic Research, Lund. Future development plans include integration with the Swedish National Heritage Board's information systems and the capacity to serve as a data source for any system.

SEAD is the official database infrastructure of the ArchLab Consortium of Archaeological Research Laboratories, and a partner in infrastructures for palaeoecology (Neotoma Paleoecology Database and Community), semantic networking and long-term human ecodynamics (dataARC cyberinfrastructure), archaeological data (ARIADNE+), heritage science (IPERION-HS, Heritage Science Sweden) and biodiversity science (SBDI - Swedish Biodiversity Data Infrastructure).

SEAD has been financed by the Swedish Foundation for Humanities and Social Sciences (VISEAD project), Swedish Research Council, Umeå University, Umeå University Faculty of Arts and Humanities, the Department of Historical, Philosophical & Religious Studies, and Lund University.

SEAD is always interested in hearing from anyone, including students and interns, wishing to undertake projects involving the database. Please contact the team should you wish to make your data available through the system, or work with us in any other capacity.

All data in the SEAD database is freely available and licensed under the license.
