About DMS-PRO
One of the main objectives of the DMS-PRO working group is to establish a comprehensive and open-access database of quality-controlled MSC cycling rates. DMS-PRO will fully evaluate the analytical procedures and uncertainties in the quantification of MSC cycling rates and will synthesize and publish its findings and recommendations on standardized operating practices.
The overarching objective of DMS-PRO is to establish an international community of practice focused on research, capacity development, and oceanographic multidisciplinary collaboration focused on the oceanic biogeochemical sulfur cycle.
Objectives
Organic methylated sulfur compounds (MSCs) play key roles in planktonic food webs as important carbon and sulfur substrates and also as infochemicals that mediate biological interactions. In addition, the oceanic emission of biogenic volatile MSCs to the atmosphere acts as a source of aerosols, which impact cloud formation and properties, and hence climate. In order to understand the role of MSCs in the Earth system, it is essential to have access to accurate rate measurements of the biotic and abiotic processes involved in the cycling of these compounds.
DMS-PRO stands for “Developing resources for the study of Methylated Sulfur compound cycling PROcesses in the ocean (DMS-PRO)” and it is a SCOR-sponsored working group, created in 2023.
The cycling of organic methylated sulfur compounds in the global ocean is regulated by complex abiotic and biotic interactions that cross trophic levels and kingdoms. While many of the most important mechanisms regulating the flux of these molecules are shown here, the group will also update the figure with new mechanisms discovered in the last two decades. The goal of DMS-PRO is to develop a resource to best quantify the fluxes of MSCs as depicted in the figure by the many different arrows. The quality-controlled open-access database will define these arrows with all previous rate measurements, and, critically, provide bounds of uncertainties in order to best inform future experimental and modeling efforts.
