This application allows you to select different paleo-oceanographic proxies collected at LSCE according to various dimensions (spatial position, depth, age, archive, material type and chronological information).

You can apply filters on dimensions such as depth, age, archive, material type and chronological information 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.
To cancel a filter, click on "reset".
You can view information about a proxy (id, position, etc.) when you mouse over its position marker. This will also highlight in bold text the corresponding row in the data table showing the proxy information, along with the species and the reference of the paper. Click on the DOI to view the listing in google scholar, the web search engine for scientific papers.
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.

Known issues:

  • The projection used is a "Spherical Mercator" with an extension to North and South limited to 85°. This is a problem for data collected at more northern or southern positions. In this case, proxy positions are set to 85°.
