 | Column name | Description |
 | ----------- | ----------- |
 | *RGIID* | Randolph Glacier Inventory v6.0 ID for the overlying glacier |
-| *sinkNr* | To identify lakes per glacier  |
+| *sinkNr* | Lake ID, unique per glacier |
 | *MIN_ELEV* | Deepest point of the lake |
 | *MAX_ELEV* | Lake surface elevation |
 | *MEAN_ELEV* | Mean lake elevation |
 | *DEPTH* | Lake depth [m] |
-| *SRFC_AREA*| Lake surface area [m²] |
-| *VOLUME* | Lake volume [m³] |
-| *IMPCT_AREA* | Lake impact predisposition area [m²] |
+| *SRFC_AREA*| Lake surface area [m<sup>2</sup>] |
+| *VOLUME* | Lake volume [m<sup>3</sup>] |
+| *IMPCT_AREA* | Lake impact predisposition area [m<sup>2</sup>] |
 | *HZRD_MEAN* | Mean slope hazard score |
 | *HZRD_MAX* | Maximum slope hazard score |
 | *LHL_MEAN* | Mean lake hazard level |
 | *LHL_MAX* | Maximum lake hazard level |
 
-Both LHL_MEAN and LHL_MAX are only available for the shapefile containing the larger overdeepenings (>10^5 m² surface area).
+### Additional information
+
+Currently, both LHL_MEAN and LHL_MAX are only available for the shapefile containing the larger overdeepenings (surface area >10<sup>5</sup>  m<sup>2</sup>).
+In this shapefile, overdeepenings with erroneous morphological characteristics (due to void filling errors in the DEM data) are excluded.
+However, they are still included in the shapefile containing the complete dataset of overdeepenings.

 # Subglacial overdeepenings
 Shapefiles of subglacial overdeepenings representing possible locations of future glacial lakes in High Mountain Asia including a first-order GLOF hazard assessment at each site.
 
-The results of this study can be used for anticipating emerging threats and potentials connected to glacial lakes and as a basis for further studies at suspected GLOF hazard hotspots.
+This dataset can be used for anticipating emerging threats and potentials connected to glacial lakes and as a basis for further studies at suspected GLOF hazard hotspots.
 
 This study is part of the [GLAMoR](https://hu.berlin/glamor) project. 
 
+### Detailed information
+This dataset contains two shapefiles of subglacial overdeepenings in High Mountain Asia. 
+1. *overdeepenings_HMA_large.shp*: A shapefile containing only overdeepenings with a surface area >10<sup>5</sup>  m<sup>2</sup>.
+1. *overdeepenings_HMA_complete.shp*: A shapefile containing all subglacial overdeepenings in High Mountain Asia with a surface area >10<sup>4</sup>  m<sup>2</sup>.
