Paleorecords & Geophysics

Lakes serve as a valuable record of the past.  Lake sediments contain an archive of the environment that can be as old as the lake itself. For some large lakes, this means we can learn about the state of the environment thousands or even millions or years ago.  

Geophysics uses the tools of physics, mathematics and chemistry to understand the structure and dynamics of Earth. Here at LLO we use acoustic remote sensing to unlock mysteries about lake basins and the processes and mechanisms that led to lake formation. 

We have many scientists at LLO who use large lakes as archives of information about the past.
