Avery Point Paleoclimate Lab 

About Us

 

Research in the Avery Point Paleo Lab (APPL) focuses on the mechanisms that govern Earth's climate variability on centennial and longer timescales.

 

Areas of research include: quantitative estimates of the ocean circulation in the geologic past, the ocean's role in the carbon cycle, and long-term variations in mid-ocean ridge hydrothermal and volcanic activity.

 

Research in APPL is based on a range of lab techniques, including analyses of stable isotopes, trace element concentrations, helium isotopes, U/Th, and radiocarbon.
