Oneida Lake is known for the available long-term data that are invaluable for documenting changes associated with both invasive species, management, and climate change. However, it is only one lake and we rely on comparisons of our data sets with lakes around the nation and around the world to deduce general trends. Many of the projects are through the Global Lakes Ecological Observatory Network (GLEON). As a site member of GLEON, CBFS are partners in several projects that benefit from comparative approaches to limnology and lake – watershed interactions. Several new GLEON project started in 2019 as part of the annual meeting in Canada that Figary, Watkins and Rudstam attended. Additional projects have developed through the interests of the scientific community in the Oneida data independent of GLEON, examples are the mussel project, the inland fish production project and the project on the connection between fisheries yield and phosphorus. Other agencies or universities than Cornell administer most of the projects listed under this heading. They do provide important insights into the structure and function of lake ecosystems and we are proud to be part of these internationally collaborative projects. We are pleased that others are using our many years of effort on Oneida Lake. To facilitate these interactions, we have made 10 datasets available (walleye, yellow perch, gillnet catches, trawl catches, limnology, phytoplankton, zooplankton, benthic invertebrates, ice cover, dreissenid mussels) on the DataONE data archiving system and update these data sets each year.
