Our second Scotland paper also came out recently. This paper reports some anomalously old OSL ages from a higher than expected shoreline in NW Scotland. We hypothesize that it may represent a MIS3 shoreline. If so, it might mean Scotland was covered by an ice sheet during MIS4. Its preliminary, but an interesting hypothesize, nevertheless.

Was Scotland covered by an ice sheet during Marine Isotope Stage 4? Insights from the pre‐Last Glacial Maximum marine terraces of northwest Scotland Raised shorelines provide important constraints on past sea levels, glacial isostatic adjustment (GIA), and rates and directions of vertical crustal motion. Although most raised shorelines across NW ...

We've had a few papers come out the last couple months. First, Elisa Medri's second paper came out in Quaternary Science Reviews. She developed a new way of reconstructing sea levels using the transgressive ravinement surface. With that she is able to push back the sea-level record for California to ~16,000 years ago.

We had a great field season in Scotland. With our colleagues, Louise, Tom, David, Jerry, and Anya from the UK, lab member Trap and I spent 2.5 weeks coring the bogs and marshes of NW Scotland collecting data to reconstruct past sea levels across the region. We hope the new data will shed light on the role RSL change may have played on the retreat of the Minch Ice Stream following the Last Glacial Maximum.

A couple years ago, we were involved with a project called WALIS, which sought to compile LIG indicators from across the globe. One notable omission from that work was Antarctica. Well, we finally followed up on that with this paper that we recently published summarizing what we know (not much) about the LIG around Antarctica.
