![]() Dates with overly large uncalibrated errors can be visually differentiated by adjusting the Max uncal. Dates can also be filtered chronologically, by entering the maximum and minimum chronological bounds (the order is not important) using the two w/date range from: to: input boxes. Dates can be filtered geographically, either by entering the name of the site(s) in the “select sites” pane, or by using the polygon selection button on the top left of the page. Dates can be visualised and filtered in two date formats: by uncalibrated bp or by median calibrated BP. By clicking on More details, the user is transferred to the Calibration tab with all the fields related to that specific date (see below).Ī number of filtering or search options are provided by the Map explorer (most of which are automatically synchronised in the Dates explorer tab). Each date is represented by a single point hovering over a point with the cursor shows the site name, and clicking on the point opens a popup with headline information about the date (unique identifier uncalibrated date median calibrated date site name material site context). In the Map explorer tab, the locations of radiocarbon dates are visualized on an interactive and zoomable map. 9600-700 BC”, acknowledgements and credits as well as some basic tutorial instructions for use of the app. ![]() This tab provides an overview and introductory information about the MedAfrica Project “Archaeological deep history and dynamics of Mediterranean Africa, ca. The Calibration and SPD tabs are linked but not synchronised to the explorer tabs. Some of the tabs are synchronised, so that, for example, a filter selection made in the Map explorer will also appear in the Dates explorer and vice-versa. The default tab on opening the app is the Map explorer. The app is structured as a tabbed dashboard with six major tabs (About Map explorer Dates explorer Individual calibration SPD (beta) Download Bibliography). The MedAfricaCarbon web app provides a graphical interface to explore the MedAfrica database, based on the Shiny platform ( Chang et al. The final database is presented here in the form of a user-friendly web app, to facilitate data exploration and informal analysis.įor more information about the database, see the open data publication Lucarini et al. These questions are explored as part of the interpretative synthesis presented in Broodbank and Lucarini (2019). presence/absence of domestic/wild species and material culture elements), allowing the first comprehensive chronological and cultural story for the prehistory of this region to emerge for a generation. To address these questions, a large and up-to-date database of published radiocarbon dates was assembled with a systematic association of key cultural markers (e.g. 9600 BC) and the arrival of Phoenicians and Greeks (between 800 and 600 BC), and to identify major factors shaping the patterns detected. The MedAfrica Project set out to produce the first comprehensive, empirical and interpretative synthesis of long-term social and economic dynamics on the African flank of the Mediterranean between the beginning of the Holocene (ca.
