&lt;p&gt;V. Tollenaar, H. Zekollari, S. Lhermitte, D. Tax, V. Debaille, S. Goderis, P. Claeys, F. Pattyn, Unexplored Antarctic meteorite collection sites revealed through machine learning. Science Advances 8, eabj8138 (2022). &lt;a href="https://doi.org/10.1126/sciadv.abj8138"&gt;DOI: 10.1126/sciadv.abj8138&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Contact: Veronica Tollenaar, Veronica.Tollenaar@ulb.be&lt;/p&gt;

&lt;p&gt;Users should cite the original publication when using all or part of the data.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;About the datasets: it includes a shapefile with the outline of the 613 Meteorite Stranding Zones (Fig. 7, &amp;quot;613MSZs.zip&amp;quot;), the observations used for classification, and the continent-wide probability to find meteorites (at 450-meter resolution, Fig. 5, &amp;quot;positive_classified.nc&amp;quot;). References to the literature are provided in the corresponding publication. Meteorite locations are based on the Meteoritical Bulletin Database (available at https://www.lpi.usra.edu/meteor/).&lt;/p&gt;

&lt;p&gt;- bias_above200m1kmbuff_expanded_dissolved: shapefile of polygons of unlabelled observations&lt;br&gt;
- meteorite_locations_raw.csv: contains locations of meteorite finds as defined in the meteoritical bulletin consulted on 05/07/2019&lt;br&gt;
- meteorite_types.csv: contains meteorite names and types as defined in the meteoritical bulletin consulted on 05/07/2019&lt;br&gt;
- validation_neg.csv: contains locations of negative observations used for validation&lt;br&gt;
- TEST_neg.csv: contains locations of negative test observations&lt;br&gt;
- TEST_pos.csv: contains locations of positive test obesrvations&lt;br&gt;
- MSZs_ranked: shapefile of ranked meteorite stranding zones&lt;br&gt;
- Test_neg4326: shapefile of locations used as negative test data&lt;br&gt;
- Cal_neg4326: shapefile of locations used as negative calibration/validation data&lt;br&gt;
- TestMSZs_pos4326: shapefile of locations used as positive test data in MSZ-level assesment&lt;br&gt;
- 613MSZs: shapefile of outlines of meteorite stranding zones&lt;br&gt;
- positive_classified.nc: netcdf of positive classified observations with their estimated a posteriori probabilities&lt;/p&gt;</subfield>
