Overview
The semester topic initiates with the organization of a conference session at the European Geosciences Union General Assembly in Vienna. In the summer term 2015, a series of lectures, workshops and side events on the topic ‘Ocean Interfaces’ will take place and the semester topic will finish with the co-organization of the SOLAS Open Science Conference (Surface Ocean Lower Atmosphere Study) as a suitable international platform to discuss aspects of ocean-atmosphere coupling.

TECHNICAL WORKSHOP
Marine Applications and Perspectives of Cavity Enhanced Optical Detection Schemes
Spectroscopy and Cavity Enhanced Absorption Spectroscopy in Ocean Sciences emerges as a promising new tool for many marine research applications. In particular, the availability of robust and user-friendly commercial instrumentation facilitates the implementation of such analyzers into first ocean-going field experiments. However, single-site trace gas detection, continuous isotope studies and autonomous monitoring applications require a thorough testing and validation of the precision and accuracy of the instruments under harsh operating conditions. Additionally, the need for direct analysis of seawater samples and the utilization of water-air or other equilibration systems constitute challenging measuring conditions that push the new technique to its limits. With more and more researchers getting involved and with first marine-related papers being published, it is time to bring together international experts in this field to critically discuss and review strengths and weaknesses of this method. The participants of the meeting will contribute to a review article highlighting their previous and ongoing work. The review article ‘Marine Applications of Cavity Enhanced Optical Detection Schemes’ will be published in an international journal.
Topics of the workshop with several talks (see programme) will be:
1. Intercomparison Studies
2. Field performance
3. Isotope Analysis
4. Emerging Marine Applications
Additionally there will be two highlight talks on:
• ‘New developments and applications of cavity enhanced spectroscopies: from optical physics to healthcare’ (Grant Ritchie, University of Oxford, UK) and
• ‘Cavity enhanced detection in liquids using waveguides’ (Hans-Peter Loock, Queen's University, CA)

MICROLAYER WORKSHOP
The Ocean Surface Microlayer and Biogeochemical Feedbacks in the Earth System
The global relevance of processes taking place on microscales is often related to their ability to influence or even trigger biogeochemical feedbacks. The workshop will focus on processes at the ocean-atmosphere interface, and aims to investigate and better constrain its role for the earth system. As environmental change modulates biogeochemical feedbacks, the effect of warming, acidification and eutrophication will be critically discussed. The results of the workshop will be summarized in a white paper.
Topics of the workshop will be:
1. Sea Surface Microlayer Characteristics – Physical, biological, chemical
2. Gas exchange processes
3. Aerosols – Production and emission
4. Advanced & remote methodologies
5. Interactions in a changing climate / Anthropogenic forcing
6. Modelling of processes across the sea surface microlayer
For each of the six topics there will be an overview talk, highlighting recent developments and unresolved questions, as well as a topical talk, which controversially discusses novel approaches, methods or visions.
The Ocean’s surface microlayer: Interface of marine and atmospheric disciplines
As part of the semester topic “Ocean Interfaces” the three-day workshop “The Ocean Surface Microlayer and Biogeochemical Feedbacks in the Earth System” was held on July 1-3 in the Wissenschaftszentrum Kiel. During the poster session on the first day and 12 keynote lectures on the second day, the diverse research within the field of microlayer science was presented by 40 national and international experts. On the last day, lively discussions took place in three breakout groups with the foci: “Surface microlayer characteristics”, “Exchange of gas, heat and momentum across the microlayer” and “Role of the microlayer for production and properties of aerosols”. Research priorities, linkages between disciplines as well as open questions and challenges were developed in these groups. As basis and road map for future collaborative research, the outcome of the workshop will be summarized and published in a white paper.

EGU special session
PICO BG3.5 (OS co-listed) Session: 'Ocean Interfaces'
Large scale changes in the ocean are often driven by small scale processes mediated by interfaces between various compartments such as sediment/ocean, ocean/atmosphere (e.g., SOLAS science), cell/seawater and particle/seawater interfaces. However, the underlying processes and mechanisms occurring at the ocean interfaces are largely unknown and therefore their impact on large scale changes is difficult to predict. This session will bring together experimentalists and modelers from chemistry, biology, geochemistry and physical oceanography to discuss the latest developments of the investigation of the accumulation, transformation and transport of climate-relevant substances at and across the different ocean interfaces.

EXHIBITION MODULE
Last year the exhibition Future Ocean Dialogue successfully celebrated its premiere in Brazil: more than 20,000 visitors saw the exhibits of Kiel marine science at five locations in the entire country. This year the exhibits were presented to the public in Germany at Kiel University for the first time. This is not yet the end of the journey for the travelling exhibition: The next presentations in Germany and abroad are already in planning.
The new exhibition module “The Breathing of the Ocean”, which was developed as part of the Semester Topic “Ocean Interfaces”, demonstrates how the ocean takes up CO2 from the atmosphere and what would happen without the ocean.
The new module will be presented as part of the public exhibition during the SOLAS conference (September 7th - 11th , 16:00 - 18:30).
First tests for the exhibition module can be seen here.

Surface Ocean Lower Atmosphere Study (SOLAS)
The international conference with approx. 300 attendees is part of the official 350th jubilee of the University and will take place in the Audimax from 7.-11. September 2015. The OSC is jointly organized with the SOLAS International Project Office in Kiel (E. Breviere, S. Kontradowitz) and the Local Organizing Committee:
Herrmann Bange, GEOMAR
Gernot Friedrichs, Kiel University
Christa Marandino, GEOMAR
Birgit Schneider, Kiel University
Emanuel Söding, ExCl Future Ocean
As part of the Semester Topic Lecture Series Prof. Hans Joachim Schellnhuber, the director of the Potsdam Institute of Climate Impact Research (PIK) will give a public afternoon lecture in German language with the title: „Menschheitserbe Meer: Seine Bedeutung, unsere Verantwortung“.
During the entire conference the public exhibition “Future Ocean Dialogue” can be visited in the Audimax. The new exhibition module “The breathing of the ocean”, that is being developed as part of the Semester Topic together with the Public Outreach group, will be presented for the first time.
