Geological Sciences, Brown University, 2001</P> <P> <B>Research</B> <BR> My research interests are broadly concerned with understanding the processes that govern interactions between the climate system, the hydrosphere, land surfaces and the sedimentary record. I investigate how both natural and human changes in the Earth system influence sedimentary processes and apply this knowledge to studies of long-term climate and environmental change. I have worked in both coastal marine and freshwater lake and river environments in locations ranging from the High Arctic to the tropical Pacific. <BR> <BR> <B>Ongoing and past research projects:</B> <ul type="circle"> <li><a href="http://www.geo.umass.edu/lake_e/">Quaternary climate and environmental change at El'gygytgyn crater lake</a></li> <li><a href="murray_lake_varves.html">High-Resoution studies of high-arctic paleoclimate from varved lake sediments</a></li> <li><a href="lake_ice.html">Climatic controls on the ice cover of Arctic lakes</a></li> <li><a href="delaware.html">Tidal and springtime sediment transport in the Delaware Estuary</a></li> </ul> </P> <P> <B>Publications</B> <BR> Melles, M., Brigham-Grette, J., Minyuk, P., Koeberl, C., Andreev, A., <B>Cook, T.</B>, Gebhardt, C., Haltia-Hovi, E., Kukkonen, M., Nowaczyk, N., Schwamborn, G., Wennrich, V., and the El´gygytgyn Scientific Party. 2011.
