  1. New paper from my colleague and friend Julio Cauhy, reconstructing extreme rainfall events in Southern Brazil over the past 7.5 ka. Julio and colleagues combined cave monitoring with painstaking petrography and careful U-Th dating to analyse detrital flood layers in speleothems from Malfazido cave. They found that extreme rainfall events are influenced by Antarctic-tropical teleconnections, and that El Nino events had an important contribution in the last millennium. It's a fantastic piece of work!

  2. Here's one of the slides from my presentation yesterday at #AGU23, featuring the research of Rebecca Chapman.

    She used functional PCA, a statistical method very suited to time series data to extract common trends and patterns in data. It is particularly robust to data gaps, which we have many of in our cave hydrology data

    If functional PCA sounds like a technique you can use, Rebecca's research is available as a pre-print and the code is online on GitHub. Links are in the image below.
