The Microbial Carbon Pump in the Ocean

3rd Meeting of SCOR WG 134

 

26-28 August 2012

in Delmenhorst, Germany

at the

 

 

Overview and Objectives

The Scientific Committee on Oceanic Research (SCOR) Working Group (WG-134) on the Microbial Carbon Pump (MCP) in the Ocean led by Dr. Nianzhi Jiao (China) and Farooq Azam (USA) and joined by 26 scientists from 12 countries was founded in 2009 and has been implemented for almost four years. The WG 134 aims at a better understanding of microbial and biogeochemical processes leading to the degradation and alteration of labile dissolved organic matter (DOM) and the formation, microbial and chemical modification of refractory DOM in the ocean.

       Dissolved organic carbon in the ocean is comparable in magnitude to the total inventory of atmospheric CO2 and its biogeochemical behavior is critically important in understanding global carbon cycling and climate change. Marine microbial processes are instrumental in shaping the chemical composition of DOM and thereby influence its residence time in the ocean.

       The MCP is a conceptual framework which intends to cover a broad multidisciplinary ground and seeks a synthesis for future research on and an in depth understanding of the kinetics and mechanistic processes of DOM dynamics in the oceans. WG 134 aims at the documentation of state of the art approaches in research on microbial processing of marine DOM, at acquiring new insights through analyzing the available data on microbial biomass, production and diversity along with DOM data from a variety of marine environments, and at identifying the priority scientific questions to provide the corresponding technical support in order to advance research in this field.

       A founding workshop to compile available knowledge and to identify questions on relevant processes in the MCP context was held in Xiamen, China, in October 2009. As a result of this workshop a first publication on the MCP as a conceptual framework was published (Jiao et al. 2010). A second workshop took place in February 2011 in San Juan, Puerto Rico. In this workshop, organized in the context of the Aquatic Sciences Meeting of the Association for the Advancement of Limnology and Oceanography (ASLO), a broad spectrum of ongoing research on various microbial and geochemical issues in relation of the MCP concept was presented and discussed. As a result, a booklet on the MCP was published as Supplement to Science (Jiao, Azam and Sanders ed., 2011).

       The workshop in Delmenhorst is the last one of the SCOR WG 134 and aims at summarizing the progress of microbial and geochemical research in the context of the MCP in the recent past and the impact of the MCP concept in microbial oceanography research with respect to DOM cycling and diagenetic alterations. In addition, future research activities within the conceptual framework of the MCP will be discussed and put forward.

       Results of the workshop will be published in the final report of WG 134 to SCOR and made publicly available on the homepage of SCOR:
