The Karst Waters Institute is sad to report that Bob Gulden, 2022 recipient of the KWI award for contributions to karst science, passed away in November, 2022. Bob had kept the database for long and deep caves of the world since 1976. Over the years he maintained the list and expanded the searchable catagories to include deep pits, largest rooms, gypsum and salt caves, and underwater caves. This online resource has been an important tool for karst researchers from around the world. Bob was also an accomplished cave surveyor and cartographer who excelled at producing detailed maps of complex and significant cave systems.
