Vale Peter Barrett, an extraordinary Antarctic scientist and founder of the Antarctic Research Centre at Victoria University of Wellington. Peter was an early voice in New Zealand to raise awareness of climate change, and his work changed our understanding of Antarctica and Earth's climate history.

I had a feeling this was going to happen. Sad news, especially given the poor state of sea ice after this winter. Looks like we won't be getting any more data for Arctic sea-ice thickness and volume for a while from PIOMAS. See: psc.apl.uw.edu/research/pro...

Screenshot of text that says: "Important Notice (3/24/2026):
NOAA NWS/NCEP has terminated the NCEP/NCAR R1 reanalysis as of March 18th, 2026. NCEP/NCAR R1 has been used as the atmospheric forcing data in the PIOMAS reanalysis . We had not been aware of this change in service which was apparently formally announced Feb 13. 2026. This means that we will have to find alternatives and generate a replacement. It will take considerable effort and time to update data streams, re-calibrate the model and generate updated time series. We don’t yet have a good sense if that’s possible with available funds and if so, when we will be able to resume production of a new PIOMAS time series. While a replacement of the NCAR/NCEP R1 as the forcing product makes ultimate sense, we would have wished for a longer time period to facilitate the transition. We are sorry what this means to our many users. PIOMAS has been in production since March 2010 and we rarely missed updates by more than a couple of weeks (except for government shutdowns). This will be longer. Check back here for updates! "

1️⃣ NEW DATA: “The Antarctic Ice Sheet is thicker than we originally realised and has a larger volume of ice that is grounded on a rock bed sitting below sea-level. This puts the ice at greater risk of melting due to the incursion of warm ocean water that’s occurring at the fringes of the continent."

These bases have made crucial contributions to scientific research, especially in understanding climate change.
