A student prepares samples that have been collected from a hand-planted seagrass meadow to analyse length of the blades, weight and root system for the SeaStore Seagrass Restoration Project at the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, June 21, 2023. Europe alone lost one third of its seagrass areas between the 1860s and 2016, one 2019 study found, releasing carbon into the atmosphere and speeding up global warming. While there are other initiatives to restore the plants worldwide, the SeaStore Seagrass Restoration Project in Kiel, run by the GEOMAR Helmholtz Centre for Ocean Research is one of the first that aims to enable citizens to do so autonomously.
