Climate and catchment influence the postglacial succession of three lakes in south‐central Baffin Island (Nunavut), Canada

open access: yesJournal of Quaternary Science, Volume 40, Issue 8, Page 1377-1391, November 2025.
ABSTRACT Understanding postglacial ontogeny in Arctic lakes helps contextualize modern‐day climatic change. We used sediment cores to characterize ecological succession in three south‐central Baffin Island lakes from deglaciation (c. 7–8k cal a BP) to present.

Small Phytoplankton Community Composition Cycles Annually With a Coastal Bloom

open access: yesEnvironmental Microbiology, Volume 27, Issue 11, November 2025.
The composition of the small phytoplankton community on the Northeast US Shelf changes gradually over the annual cycle. With a combination of analytical tools, we characterise these repeated transitions over a 9‐year period and relate them to changes in cell concentration.
