AB: The adoption of uniform protocols for basic characterization of sedimentary components and sample curation facilitates multiproxy analytical approaches to paleolimnological studies. Multisensor automated core logging, high-resolution imaging, and macro- and microscopic identification of sedimentary structure and composition provide the basis for all future sediment analyses. These fundamental core descriptions also allow other researchers to assess rapidly the potential for studies beyond the scope of the original project; proper core curation assures the maximum scientific benefit is obtained from the initial investment required to retrieve sediment cores. The Limnological Research Center (LRC) has developed a Core Facility (Core Laboratory and National Lacustrine Core Repository) that supports paleolimnological efforts at all scales with instrumentation and accumulated expertise for basic core description and curation. With support from NSF and the University of Minnesota, the Facility provides these services to researchers visiting from any institution at minimal cost or free of charge. The Repository now curates several thousand meters of core from lakes around the world, both from the Global Lake Drilling (GLAD) Projects and from smaller-scale expeditions. These cores and the open sample distribution policy assist the community in building a global network of continental paleoenvironmental records.
