As part of his service to the scientific and global community, Dr. Williamson serves on several national and international panels and review boards including the United Nations Environment Programme Environmental Effects Assessment Panel (UNEP EEAP) on ozone depletion and climate change, and the Freshwater Indicators Technical Team for the National Climate Assessment (NCA FITT).
The UNEP EEAP is one of three assessment panels created to keep all of the nations that ratified the Montreal Protocol informed about the current status of ozone depletion and climate change through an annual report to the United Nations. The latest full UNEP EEAP report appeared in the special issue of Photochemical and Photobiological Sciences (March 2019 issue). Smaller annual reports are also published each year, with major reports every 4 years.
Dr. Williamson has published several papers with members of the UNEP EEAP and others on Solar Radiation in a Changing Climate (Nature Climate Change), UV effects on pathogens (Scientific Reports), and UV effects on sustainability (Nature Sustainability).
The Miami Ecological Big Data Initiative (MiEBDI) facilitates student and faculty access to and analysis of ecological “big data” from around the world to address critical threats to ecosystems and the valuable services that they provide.
The Lacawac Sanctuary and Biological Field Station is located on Lake Lacawac, a key field site and part of our long-term database. With a new, state-of-the-art laboratory on site, lab members spend summers at the field station conducting experiments and continuing our long-term monitoring program. Long term weather data have been collected at this field station by Bruce Hargreaves (Professor emeritus from Lehigh University).
The NSF-funded Environmental Data Initiative (EDI) is a repository for long-term data from field stations, LTER sites, and LTREB programs. Several data sets from Miami can be found on EDI’s site, including data from the Global Change Limnology Laboratory as well as the Vanni aquatic lab. Long term data on the water column temperature, lake level, and weather of Lake Lacawac are also available.
Our lab is active in GLEON, with members of all levels (including undergraduates) participating. Dr. Williamson is a co-moderator for the Climate Sentinels Working Group where he and his graduate students are actively involved in several projects.
