Ocean Deoxygenation Conference 2018 (Kiel, Germany)

The deadline for abstract submission to Ocean Deoxygenation Conference is March 31st, 2018. This promising conference organized by the Collaborative Research Center SFB 754 will focus on past, present and future drivers and consequences of ocean deoxygenation. The biggest names who work on modern deoxygenation were invited as keynote speakers who will lead each one of the scientific topics presented at the Audimax auditorium in Kiel University.

It will be awesome to also see a good participation of early career scientists! Hopefully I will be able to make it there myself too.

Goldschmidt 2018 Session: Controls, Patterns, and Consequences of Organic Matter Burial

Dear friends! Please consider submiting an abstract and attending our session at Goldschmidt 2018 in Boston, USA:


07c: Controls, Patterns, and Consequences of Organic Matter Burial

Keynote: David Burdige (Old Dominion University) 

The geologic record captures only a portion of the complex biogeochemical interactions involving marine primary productivity. Apparent decoupling between export production in the water column and burial of organic matter as observed in modern environments has led to strong debates on the fidelity of classic productivity proxies (Corg, excess-Ba, barite, organic-P, biogenic SiO2). Common problems are caused by variable reactivity of organic matter, diagenesis, changing accumulation rates, and oceanic anoxia leading to gaps in the paleorecords and artifacts reflecting differences in proxy preservation rather than actual changes in the export of organic matter. Disentangling individual processes is often challenging; however, growing interest in proxy development and state-of-the-art analyses has led to major breakthroughs. Biologically active trace elements (e.g., Cd, Cu, Fe, Ni, Zn), their emerging isotopic systems, and biomarkers can delineate changes in primary productivity through time. We welcome contributions related but not limited to reconstructions of organic burial and the broad implications for carbon cycling spanning the Mesozoic to recent using classic and emerging proxies. Those tracers include biologically active trace elements, their isotopes, and organic compounds. We also encourage related submissions on the geochemistry of settling particles and sediment chemistry, including pore waters in modern marine settings. Studies are also welcome that address preservation and transformation of productivity proxies via metabolic redox pathways both in the water column and marine sediments.

See you in Boston!

Consider submitting to “Facing Marine Deoxygenation” Research Topic at Frontiers

Great opportunity to submit a manuscript to an important research topic: “Facing Marine Deoxygenation”. As global temperature trends continue to rise many marine regions are experiencing a slow decrease in dissolved oxygen. This has been attributed to the direct effect of warming on oxygen solubility and indirect climatic and oceanografic feedbacks not yet well understood. This research topic invites the community to address the complex interactions that lead to past, present and future changes of deoxygenation, significantly exacerbated by anthropogenic pressure.

Release: GEOTRACES Intermediate Data Product 2017

The GEOTRACES group just made the new edition of the Intermediate Data Product publicly available. It was announced and released during today’s special event at Goldschmidt conference (Paris, France). The database that now includes the Pacific and Southern Ocean revolves around several remarkable discoveries such as the importance of dissolved Fe supply from hydrothermal vent systems into the ocean (Fitzsimmons et al., 2017).
