Monitor water isotopic composition inside trees?!!!
Our main working horse on the ground got finally published, the Borehole equilibration method. Its journey started in April 2018 Sweden, went to Freiburg Germany in 2019, to Costa Rica and Arizona in 2020. The paper includes results of the first two experiments but stay tuned for further publications!
