Bear Lake Data Repository

Bear Lake Watch Announces the Establishment of the Bear Lake Data Repository

Dr. Jeffrey R. Nielson, of the Utah State University, Department of Watershed Sciences, Logan, Utah, has created a comprehensive centralized open-access repository for environmental datasets related to Bear Lake. The Bear Lake Data Repository (BLDR) is available to researchers and the general public.

The BLDR spans decades of work in which physical, chemical, and biological data from numerous scientists have been carefully curated. The BLDR now serves as a foundation for comprehensive data archiving for the future. As a result, researchers can download data and conduct studies combining new and earlier data relating to Bear Lake. Any scientists interested in augmenting the BLDR with additional data should contact the Bear Lake Watch Science Committee at science@bearlakewatch.com to formally request to add more data to the BLDR.

Bear Lake Watch’s strategy is to support science and the scientific community in developing, processing, and disseminating scientific information that can help to keep Bear Lake clean, deep, and blue. We are proud to serve as the repository manager of this important and growing body of scientific information relating to Bear Lake,” said Gregory C. Critchfield, MD, MS, and Bryce Nielson, Co-Chairs of the Bear Lake Watch Science Committee.
