Water and ice characteristics from Hobart Lake National Wildlife Refuge, Barnes County, North Dakota, USA, 2021

This data release presents data that were collected as part of a larger effort to refine knowledge pertaining to the origin, composition, and seasonality of dissolved organic matter in lakes. This work was part of an international collaborative effort with the Global Lake Ecological Observatory Network (GLEON). Water samples were collected monthly during 2021 and shipped to GLEON for determination of dissolved organic matter. In conjunction with each monthly sample event, several water-quality variables and ice thickness were measured. Data from this collaborative study will be used to understand how the origin and composition of dissolved organic matter varies through time.
