Lake Titicaca Drilling Project (LTDP) in Bolivia and Peru aimed to recover a long, detailed climate record from Lake Titicaca, the deepest large freshwater lake in South America. In early 2001, a team drilled three sites (seven drillholes) around the lake with the GLAD800 drill rig, extracting 797 m of drilling and recovering 625 m of core, of which 593.6 m were lake sediments. Core recovery was about 95% of the cored length and roughly 75% of the total drilled length. Lake Titicaca sits high in the Andes and provides a continuous climate archive essential for the Pole-Equator-Pole paleoclimatic transect across the Western Hemisphere. LTDP was designed to contribute to this transect by delivering a long, continuous environmental record. Scientists hoped to learn how precipitation, lake levels, and regional climate varied over thousands to tens of thousands of years, shedding light on how the Andean and South American climate responded to global changes and improving future climate predictions.
