Successful Launch of Semester Topic „Ocean Interfaces”

OceanInterfaces_1The semester topic "Ocean Interfaces - From Nanoscales to Global Impact" of the cluster of excellence "Future Ocean" highlights and challenges the question how nano- and microscale processes taking place at interfaces (in a broad sense) impact mesoscale and in the end global (biogeochemical) cycles. Why should we care – as a society facing global warming and environmental pollution – about very specific basic natural science problems? From a scientific perspective, the semester topic sets a focus both on technical aspects of modern analytical techniques as well as biogeochemical feedbacks such as warming, acidification and eutrophication triggered by key processes mediated by interfaces. The semester topic, jointly organized by Gernot Friedrichs (Physical Chemistry, Univ. Kiel), Hermann Bange (Chemical Oceanography, GEOMAR), and Anke Schneider (Scientific Coordination), hosts a series of events including two workshops, a public lecture series, and the SOLAS Open Science conference. Moreover, a new exhibition module “The Breathing of the Ocean” is being developed for the "Future Ocean Dialogue" exhibition demonstrationg how the ocean takes up CO2 from the atmosphere.

OceanInterfaces_2The Semester Topic has been sucessfully launched on April 17 with the organization of the special session "Ocean Interfaces" at the EGU General Assembly 2015 in Vienna. Contributions ranged from laser spectroscopic investigations of marine interfaces on a molecular scale over photochemical production of volatile organic compounds in the presence of monolayers at the air-sea water interface to an improved climatology of CO2 ocean surface flux for the North Atlantic and Arctic waters.


Right after the conference, the two-day workshop “Marine Applications and Perspectives of Cavity Enhanced Optical Detection Schemes” took place from 20-21 April. A group of 25 scientists coming from as far as Australia and Canada presented their ongoing research and especially their experience with “Cavity Enhanced Optical Detection Techniques” during the sessions “Field Performance”, “Isotopes“, and “Perspectives and Emerging Marine Applications”. Two highlight talks about “Chemical sensing with optical waveguides” (Loock, Queens Univ., CA) and “New developments and applications of cavity enhanced spectroscopies: from optical physics to healthcare” (Ritchie, Oxford Univ., UK) complemented the program. The list of participants assembled representatives of most of the national and international working groups actively using this new type of trace gas analyzers in the marine environment, hence the presented research gave a comprehensive overview of the current status of this field. Also Inga Piller and Ibrahim Sadiek presented their recent results as a joint talk and two posters. The first day closed with active discussions during the poster session, followed by a marvelous dinner above Kiels’ roofs with view onto the fjord. Emphasis on the second day was to summarize all aspects and to discuss the diverse applications, perspectives and challenges of the method in marine sciences. Therewith the road was paved for a first review article with already worked out chapters as a road map for future work.
