I have just discovered a Jane Austen manuscript that the publishers rejected. In the novel she describes teaching time series analysis to MSc students - it is called "Variance and Variability"

How is carbon stored in salt marshes? Great fieldwork on the Solway Firth with postgrad Jinny. Always good to find a buried soil horizon. @durhamearthsci.bsky.social

For a peat to form you don't just need wet conditions you also need stagnant conditions

Spring reminder, as people start to think about gardening: NEVER buy compost with peat it in (inexplicably still on sale). If it does not say "peat free" in big letters, do not buy it. Peat is incredibly valuable in peat bogs, for rare biodiversity and as a carbon store. Don't put it on your garden!

OLIGOTREND, towards a global database of multi-decadal chlorophyll-a and water quality timeseries for rivers, lakes and estuaries
Abstract. Reversed eutrophication, called oligotrophication, has widely been documented globally over the last 30 years in rivers, lakes, and estuaries. However, the absence of a comprehensive and har...
