||The Indiana Geological Survey (IGS) has a collection of approximately 40,000 processed grain-size sediment samples. These samples are kept in individual packets labeled with an identifier that are stored in about 700 core boxes. Each box is hand-labeled, but the label does not list the attributes of the packets within. The IGS also has descriptions and calculated statistics for these samples in both paper and digital formats. However, the sample and its analysis are not tied together in an inventory or linked in a database. The collection originated from other samples derived from the IGS unconsolidated sediment sample collection, which contains drill-cuttings from more than 4,000 water wells; these unconsolidated sediment samples are linked to the IGS Gamma-Ray Log Database.
||Inventory and catalogue approximately 40,000 grain-size sediment samples that are stored in approximately 700 core boxes and analyze/associate them with existing IGS records and databases.
||Enter the data from the grain-size sample boxes and analysis records (standardized IGS inventory tracking QR codes and identification information) into the IGS Inventory Database.
Make these records and databases available to researchers, clients, and customers online via IndianaMap, an interactive map and geographic information system (GIS) that is already in place at the IGS (http://maps.indiana.edu).
||Once the grain-size sediment samples have been inventoried and catalogued, they will be made available to researchers at the IGS, academic researchers, and the public, who can examine these samples onsite upon request. The final product will also include links of the archived samples to the IGS Gamma-Ray Log Database. Information pertaining to sample sets will be available as a GIS layer named Geology Surficial Gamma Ray Logs on the IndianaMap website, which is hosted by the IGS (http://maps.indiana.edu/index.html?x=607654&y=4381692.5&z=0&sBasemap=bm1&URLLayers=Geology_Surficial_Gamma_Ray_Logs).
||The grain-size sediment samples are currently used by IGS scientists for mapping, resource estimation, and other research projects. The samples are rarely used by external customers because of the lack of knowledge of their existence and limited accessibility of the collection. By cataloguing these samples and updating digital databases, the IGS will make the samples more readily available for examination by our staff, researchers, clients, and customers.
