Together with students and colleagues I have cored a lot of lakes over the years, from remote high-elevation lakes in the Rockies, to frozen ponds in northern Vermont. The reconstruction of past environmental conditions from the information contained with these lake cores, an approach known as paleolimnology, has been a major part of my research since graduate school.  For the field component of these projects I have a custom-designed cataraft coring platform that can be transported by pack animals. I also have an array of sediment corers including a percussion corer, a Russian peat corer, a Livingstone corer, and a UWITEC gravity corer.  For analysis of sediment properties my lab is equipped with a Leco TGA-701 thermogravimetric analyzer, a Thermo Fisher Flash 2000 elemental analyzer, a Horiba LB-950v2 grain size analyzer, a Quantachrome Pentapycnometer, a freeze dryer, and a Thermo Aquamate spectrometer for quantification of biogenic silica content.  All these tools allow for a wide range of analyses and support the generation of some detailed datasets.  Some recent results of work with lake cores include an interpretation of post-glacial environmental change in the Ruby and East Humboldt Mountains of Nevada, a massive compilation of post-glacial lake records from the Uinta Mountains in Utah, and a revealing assessment of how the total amount of carbon stored in all the Uinta Mountain lakes compared with the amount released each year by human activity in Salt Lake City.
