From the PUFINS site:

Scientists hope to recover cores from the Holocene period (the last ~12,000 years) to reconstruct sea-surface temperatures in the North Atlantic Ocean by examining the changes in alkenones recorded in the fossils found in the sediments. This data will allow researchers to address questions about the “Holocene Conundrum”, an issue hotly debated in the climate community, where cooling trends are observed in the North Atlantic during an otherwise warming world.
