# Get Offshore Geology Data items

`GET /collections/offshore-sample-geological-data/items`

This layer provides geological descriptions associated with offshore sampling activities. It contains a variety of geoscientific observations; these include rock/sediment classification, grain size, sorting, sphericity, roundness, hardness, plasticity, presence of flora or fauna, colour, chronostratigraphy and lithostratigraphy. Note that this layer contains data at depth. Related data in Offshore Sample Data - Activity & Scan collection.
