The figure shows an advertisement for the EGU 2026, which is taking place from 3rd to 8th May 2026. Abstract submission is open until Thursday, 15th January 1 pm CET. Deadline for support application is open until Monday, 1st December 1 pm CET. Below this information, four fotos of peatlands are displayed. On the top left, rannoch-rush is shown to grow among red peat mosses. On the top rigth, there is a blocked ditch in a grassland. On the bottom left, a paludiculture site with reed and cattail is shown. On the bottom right, there is a picture of a restored peatland with cotton gras and pools of open water.

Key message: Measuring dry bulk density is as important as measuring organic carbon content when estimating organic carbon stocks.
Shouldn't surprise, but needs to be said.
