Application of the sympagic diatom-produced, C25 highly branched isoprenoid (HBI) termed IP25 to paleo-sea ice reconstruction has confirmed its utility as a qualitative seasonal sea ice proxy. Combination of IP25 and a pelagic biomarker into the Phytoplankton-IP25 index (PIP25) …

Sea surface temperature (SST) is a crucial quantity for interpreting past climate variations, yet reconstructing historical SSTs from ship-based measurements is challenging because of varying biases that are on the order 0.1°C to 1°C. Whereas SST biases are complicated and can a…
