Dissolved organic matter (DOM) constitutes one of the largest actively cycled carbon reservoirs globally and is involved in significant fluxes between land, oceans and atmosphere. Recent work acknowledged the importance of DOM transformations in element cycling (C, N, P, others) and planktonic/microbial foodwebs, and further highlighted important roles in aquatic photochemical processes, trace gas production, ocean optics and remote sensing. Despite the biogeochemical importance of DOM, further progress is needed towards an improved understanding of its composition, distribution, transformations, and ecosystem function.
This session invites contributions on DOM biogeochemistry across the entire range of aquatic environments. Examples of relevant research areas include:
Distribution and geochemical characterisation of DOM;
DOM and element cycling (C, N, P) within planktonic/microbial foodwebs;
Trace gas production, cycling and DOM photomineralisation;
Optical characteristics and cycling of coloured DOM (CDOM);
Impact of CDOM on ocean optics and remote sensing.
