My first paper, based on work I did for my MSc thesis, has been published in PLOS One! it’s all about how much organic carbon is in sediments that are targeted by extractive industries in northwest Europe, and how that’s changed over time. doi.org/10.1371/jour...

Super interesting historical ecology paper describing 300 years of degradation in Welsh estuaries and coasts. If conservation and restoration efforts are to be successful then we need a better understanding of the scale of historical change in our marine environment!

About 5 years in the making: (there really is) limited evidence on the impacts of #windfarms on #fisheries species. Wind is a solution to the climate crisis, but we also need food security. These are tough, complex choices and we need evidence to support them. onlinelibrary.wiley.com/toc/14672979...
Image shows the amount of evidence available on windfarm impacts on fisheries for different types of species. The amount of evidence is represented by lines, with thicker lines meaning more evidence. Most of the lines are thin, signalling little available evidence; the most evidence was found for demersal and reef-associated roundfish.
