The Lake Junín Drilling Project
Project Acronym: JUNIN | State: Completed | Expedition ID: 5056
Lake Junín, located at 4000 m asl in the inner-tropics of the Southern Hemisphere, is a scientifically well-studied lake. Therefore it is a prime target for drilling.
The lake contains a thick (>125 m) sediment package deposited at a high rate (0.2 to 1.0 mm yr-1). Lake Junín is one of the few lakes in the tropical Andes that predates the maximum extent of glaciation and is in a geomorphic position to record the waxing and waning of glaciers in nearby cordillera. Lake Junín is a scientifically mature site that will yield critical scientific insights that only drilling coupled with analysis by a select international team of scientists can unlock.
