🌊 How do we collect sea ice to measure tor trace elements and isotopes? You need a big drill to collect the core and then a lot of patience to shave down the outsides with a ceramic blade…to get clean ice to melt and analyze. Dr. Tia Anderlini on the trigger here.

Huge paper for the Arctic Ocean published today in @science.org - a new 30,000 year history of Arctic Ocean sea-ice cover reconstructed from the accumulation of cosmic dust-derived helium-3! www.science.org/doi/10.1126/... (1/n)
Cosmic dust reveals dynamic shifts in central Arctic sea-ice coverage over the past 30,000 years
Arctic sea-ice loss affects biological productivity, sustenance in coastal communities, and geopolitics. Forecasting these impacts requires mechanistic understanding of how Arctic sea ice responds to ...

The oldest research vessel in the country was just retired. What does it mean for Rhode Island scientists? - TPR: The Public's Radio
The R/V Endeavor, which spent the last 49 years operating out of URI’s Narragansett Bay Campus, was retired last month. Possibly took a tour of the vessel before it’s decommissioned.
