The Blue Carbon Lab has launched a global initiative - TeaComposition H2O - to help the world understand the role of wetlands in carbon sequestration. To do this, we are buring Lipton Green and Rooibos teas for 2-3 years to study their carbon decomposition rates! Our aim is to identify the aquatic ecosystems (seagrass, saltmarsh, mangrove, inland wetlands, swamps etc) that have a greater potential to store (or sequester) carbon as shown through slower tea decomposition. Those ecosystems may be better at helping mitigate climate change. For the sake of logistics and fieldwork safety, we hope to have citizen scientist groups help coordinate and assist citizen scientists in this project worldwide.
