This project was first discussed at GLEON 21 in Huntsville, Canada.
Dissolved organic matter (DOM) is central to the functioning of lakes, but its molecular composition remains a "black box" at large spatial and temporal scales. This project aims to understand how the origin and composition of DOM varies through time using ultra-high-resolution mass spectrometry and its association with biogeochemical data collected from high-resolution sensors (e.g. dissolved oxygen, chlorophyll a, fDOM/CDOM). We are interested in collecting water samples at a monthly interval for 1 year from the deepest point in your study lakes. We will process all samples using a standardised protocol and make data freely available for reuse on a cloud server.
Sampling aims to run between January 2021 and December 2021 with standardised consumables provided to all participants, who will follow a common protocol (available here).
