Meredith Parish is working on reconstructing temperature based on lipid membrane assemblages and precipitation based on carbon and hydrogen isotopes measured in lake sediment cores from Lake Towuti in Indonesia. The composite Lake Towuti sediment record has lake sediment that spans the past 1.1 million years!  Meredith is going to produce continuous temperature and hydroclimate records that extend back until 1.1 Ma over the next couple of years. Understanding temperature and precipitation variation in Indonesia can help us uncover the driving forces of climate in one of the most populated regions on Earth.
