Soils and geomorphology of “Salada de Chiprana” RAMSAR wetland, NE Spain

Description

The “Salada de Chiprana” (41°15'N, 00°12'E) is a Nature Reserve in the semiarid central Ebro Basin (Aragón region) and the only permanent hypersaline lake in Western Europe. The wetland is included in the List of RAMSAR Sites of International Importance from 1994. The data presented here belong to the research projects “AGROWET”, funded by MCIN/AEI/10.13039/501100011033 and by the “European Union NextGeneration EU/PRTR”, and “ISABEL”, funded by MCIN/AEI/10.13039/501100011033 and by “ERDF A way of making Europe”. In these projects we have studied the geomorphology and the soils of selected landforms of “Salada de Chiprana” Nature Reserve. The dataset includes an Excel spreadsheet with the soil data and a zip folder with the geomorphological map. The Excel file “SoilProfile_Chiprana.xlsx” is organized in four sheets: the Sheet #1 “Notes” includes comments on laboratory methodology; the Sheet #2 “Site description” includes the introductory field description of the profile site together with date and location; the Sheet #3, “Soil profile description” contains the detailed horizon descriptions; the Sheet #4 “Soil analysis” comprises the laboratory results of the physical and chemical analysis of 28 soil samples. The methodology for describing the sites and soils are based on Schoeneberger et al. (2012) and SINEDARES (C.B.D.S.A., 1983), and Soil Taxonomy (Soil Survey Staff, 2022). The compressed folder “Geomorphology_Chiprana.zip” includes two vector datasets, i.e. the shape of polygons “2024_carto_chi_polygon” and the shape of polylines “2024_carto_chi_line”. The two geographic layers are projected in European Datum ETRS89/UTM zone 30N, and include the five components necessary for visualization in a Geographic Information System. The geomorphological map is based in the stereoscopic photointerpretation of the USAF aerial photographs (1956-1957) at 1:33,000 scale, provided by the Spanish Cartographic and Photographic Center (CECAF). We included in this dataset the folder “SoilPhotographs” with photographs of the soil profiles and ageneral landscape view, together with the file “Profile&OSLdating_chi_point” with the location of the soil profile and dating samples.

Steps to reproduce

The soil profiles can be localized by their UTM (ETRS89/UTM zone 30N) coordinates and the laboratory data can be reanalyzed and represented with different graphic and statistical programs. The UTM projected shapes can be opened in a Geographic Information System (GIS software) or uploaded as a layer in a web browser.
