Description:


This viewer allows you to interactively explore and download samples from the Eurasian Modern Pollen Database (EMPD).

Filtering the data

Click the Filters tab to apply filters to the database

You can apply filters on meta informations such as precipitation, temperature, age uncertainty, etc. by interacting with the charts. All charts are linked together so that filters applied in one chart will update the others, as well as the map.

Some meta data is filtered by menus. Simply select the entry in the menu to apply a filter.

To cancel a filter, click on "reset".

Navigating the map

You can view information about a sample (name, site, position, etc.) when you click on one of the markers. If you hover over it with your mouse, the sample will also be highlighted in bold text in the Meta data table tab.

When several proxies share the same location, they are grouped together in a cluster (colored circles). Click on a cluster to display all the proxies it contains.

Red clusters represent more than 100 proxies, yellow clusters contain more than 10, and all others are green.

Accessing the sample Data

When you click on a sample in the map, you can see the pollen percentages in the Pollen diagram tab below it.

Additionally, you can see a diagram of Precipitation and Temperature based on the data from WorldClim in the Climate diagram tab.

You can select samples through the button. Either use the popup or the checkbox in the Meta data table to select a single sample, or use the button below the map to select all currently selected samples.
To download the data, as a tab-separated file, use the button.
