Portable luminescence for rapidly identifying tsunami dynamics and responses in saltmarshes Open
Identifying sedimentary signatures of tsunamis within long-term records (hundreds to thousands of years) is time and labour intensive using existing techniques. The lack of rapid identification restricts our ability to reconstruct past (pa…

Untangling nutrient co‐regulation of ombrotrophic peatland development Open
Ombrotrophic peatlands are the largest terrestrial store of global carbon (C). While hydroclimate controls over peatland development are well known, the importance of nutrient fluxes has been researched less. Atmospheric nutrient fluxes to…
