Help on the Results MapX
This window can be dragged by its header, and can be resized from the bottom right corner.
Clicking the Layers button - the blue square in the top left of the Results Map - will display a list of map layers you can add or remove
from the currently displayed map view.
The Results Map and the Results Table
- The Results Map displays the centroids of the geographic bounds of all the results returned by the search.
- Results that are displayed in the current map view will be highlighted in blue and brought to the top of the Results Table.
- As the map is panned or zoomed, the highlighted rows in the table will update.
- If you click on a centroid on the map, it will turn yellow and display a popup with details for that project/dataset - including a link to the landing page. The bounds for the project(s)/dataset(s) selected will be displayed in red. The selected result(s) will be highlighted in red and brought to the top of the table.
- The default table sorting order is: Selected, Visible, Date (descending), but this can be changed by clicking on column headers in the table.
- Selecting Show on Map for an individual row will both display the geographic bounds for that result on a mini map, and also display the bounds and highlight the centroid on the Results Map.
- Clicking the 'Show boundaries' checkbox at the top of the Results Map will display all the bounds for the filtered results.
Defining a search area on the Results Map
- If you click on the Rectangle or Polygon icons in the top right of the Results Map, you can define a search area which will be added to any other search criteria already selected.
- After you have drawn a polygon, you can edit it using the Edit Geometry dropdown in the search form at the top.
- Clicking Clear in the map will clear any drawn polygon.
- Clicking Search in the map, or Search on the form will have the same effect.
- The returned results will be any projects/datasets with bounds that intersect the polygon.
- Use the Exclude project/datasets checkbox to exclude any projects/datasets that cover the whole Antarctic region.
Viewing map layers on the Results Map
To sort the table of search results, click the header of the column you wish to search by. To sort by multiple columns, hold down the shift key whilst selecting the sort columns in order.

Tracing Past Methane Variations with Stable Isotopes in Antarctic Ice Cores |
This dataset includes ~60-year resolution measurements of the Carbon-13 and Deuterium isotopic Composition of Atmospheric Methane (δ13C-CH4 and δD-CH4, respectively) of gas bubbles from the WAIS Divide Replicate Ice Core. All measurements were made at the University of Bern Ice Core Laboratory (Bern, Switzerland) using a new methane stable isotope analytical system. The data includes depth-adjacent replicate samples (separated by no more than 0.3m of depth). The data are displayed as a function of WAIS Divide Replicate Core depth and were corrected for gravitational and diffusional fractionation that occurs in the firn column according to Buizert et al., 2013. 1-sigma measurement uncertainty is also included and is determined from analytical uncertainty and uncertainties associated with diffusional and gravitational fractionation.
