Abstract
A group of fifty scientists and students from eight countries met on the campus of UNAM (Universidad Nacional Autonoma de Mexico) in Mexico City on 4–8 March 2012 to plan for a program of continental drilling that will address a wide range of ongoing issues and hazards facing the Mexico City region. The initial impetus for the workshop was investigation of a long and continuous climate and ecological record preserved in the lake sediments underlying the city. Workshop attendees included participants with scientific interests in sediment core and borehole instrumentation in this region, including experts in volcanology, seismology, hydrology, geodesy and the associated geological hazards. The workshop was supported by the International Continental Scientific Drilling Program (ICDP) and UNAM.

Summary
N unique and remarkable record of climate history directly relevant to millions of people. An understanding of past variability in the region-. -90 al hydrological regime, including variations in monsoonal precipitation, provides a basis for evaluation of ongoing climate change. The sediments can provide histories of volcanic activity, and their physical properties are relevant to models of seismic wave propagation in the basin as well as to understanding its intense subsidence and regional groundwater resources
