SILICAMICS 5 conference
We are pleased to announce that the next SILICAMICS Conference will take place in Vigo, Spain, from 27 September to 1 October 2027, hosted at Hotel Attica21.
The SILICAMICS interdisciplinary conference series was launched in 2015 under the initiative of the international Silica Group (Brest, France), with the aim of developing an integrative approach to better understand the geochemical and biogeochemical cycle, biosilicification and silicifiers across past, present, and future oceans. By bringing together experts in chemistry, biogeochemistry, biochemistry, physiology, and genomics, SILICAMICS provides a unique international forum for scientists exploring the many facets of silicon cycling and silicification processes across marine and terrestrial environments. The meeting brings together researchers from different disciplines to exchange ideas, foster collaborations, and discuss the latest advances in our understanding of silicon cycling across marine and terrestrial environments.
The 2027 edition will continue this tradition by combining a stimulating and collaborative atmosphere, oral presentations, poster sessions, and ample opportunities for scientific discussions and networking. The conference format will include a welcome reception, shared accommodation and meal setting to encourage interactions among participants. Building on the strong and active SILICAMICS Early-Career Researchers community, dedicated activities will be organised to further promote exchanges, networking, and collaboration among early-career scientists.
The scientific programme will cover five main themes:
- Geochemical Processes and Fluxes
- Marine and Terrestrial Silicifiers
- Silicification and omics
- Modelling
- Polar Seas
We look forward to welcoming the SILICAMICS community, as well as new colleagues interested in the many facets of silicon science, to Vigo and to sharing an exciting week of scientific exchange, discussions, and collaborations focused on the fascinating role of silicon in Earth’s systems.
Further information about registration, abstract submission, and the detailed programme will be announced soon.
ODATIS celebrates it’s 10th anniversary at IUEM
From 2 to 4 June 2026, the IUEM hosted the general assembly of ODATIS. This year’s event was a special occasion, as it marked the 10th anniversary of this Ocean Data and Services cluster within the Data Terra research infrastructure! Over the past decade, ODATIS has established itself as a key player in the dissemination, promotion, sharing and management of ocean observation data, bringing together a broad community drawn from major national and international programmes.
In attendance were institutional partners (CNRS, CNES, Ifremer, IRD, Shom, Marine Universities, Cerema), members of the scientific and operational community, data managers, public sector representatives and private partners. A total of 158 people gathered for three days of workshops, plenary sessions and discussions focusing on institutional and scientific issues, looking back at the past and looking ahead to the future. These sessions provided an opportunity to revisit major advances, flagship projects and significant milestones, whilst setting a course towards new horizons to be explored.
The final session on Thursday 4th focused in particular on the social and environmental impact of digital technologies, especially those arising from research, complementing the exhibition on digital sobriety currently on display in the institute’s corridors.
A special evening event was organised at Espace 70.8 ‘A Museum for the Ocean’, at the Ateliers des Capucins, allowing participants to enjoy a convivial immersion and continue discussions throughout the museum tour. There were lively discussions around several observation sensors on display (satellites, Argo floats, tide gauges, etc.), with the oceanographers present acting as guest representatives for the ODATIS 10th anniversary!

SAMOS launches academic year with inaugural week at Nelson Mandela University
From 2-6 February 2026, the South African Master in Ocean Sciences (SAMOS) marked a major milestone with the successful completion of its inaugural week at the Ocean Sciences Campus of Nelson Mandela University. The programme brought together its first student cohort, registered at the University of Cape Town, alongside lecturers and consortium partners from across South Africa and internationally, in preparation for the start of the teaching and the next phase of the project.
The week provided students with an opportunity to become familiar with their new academic environment, complete administrative requirements, and engage directly with course conveners, lecturers, and supervisors. This initial week laid a strong foundation for the academic journey ahead and fostered a sense of academic community that will support students throughout their studies.
“Students have reflected that the orientation programme had fostered a sense of belonging, clarifying academic expectations, and establishing collaborative relationships that supported their integration into the research community,” said Mr Brishan Kalyan, SAMOS programme manager.
Following orientation, the formal teaching commenced on Monday, 9 February, launching nine months of coursework that will equip the students with foundational knowledge in socio-ecological systems, dynamics of African marine ecosystems and quantitative skills, among others. Students will later tailor their learning through elective modules, specialising in fields such as marine biology or operational oceanography. Diverse seminar programmes and invited guest lectures will further expand exposure to international research, innovation, and career pathways. Upon completion of the coursework, students will undertake their minor dissertation at one of the SAMOS partner institutions.

The inaugural week also enabled the SAMOS lecturers, from nine South African universities and specialised institutions to meet in person before the teaching activities and classes commence. The gathering provided time to explore the Ocean Sciences Campus facilities and engage with colleagues across the consortium. On Thursday, 5 February, lecturers participated in a session focused on pedagogical alignment between modules and on building cohesion among the teaching team.
Later, Dr Shaun Deyzel, Science and data coordinator at SAEON’s Elwandle node, presented national observation platforms and datasets available to both lecturers and students. Mr Kalyan then guided members of the teaching team on a tour of the laboratories, showcasing the infrastructure on the ocean sciences campus. The day concluded with a social moment convening students, lecturers and staff all together.

The following morning was dedicated to coordinating field trips and practical sessions across the curriculum. This collaborative approach, unique within the field of ocean sciences, allows students to benefit from a wide spectrum of perspectives drawn from expertise across institutions throughout the country and abroad.
The SAMOS consortium also convened a project meeting to prepare for the second phase of implementation. The upcoming stage will prioritise expanding scientific collaborations between South African and European partners, enhanced teaching and supervision capacity, and stronger engagement with socio-economic stakeholders. Together, these actions will enrich the students’ learning experience while supporting long-term professional development and impact.

MethanOcean meeting
Oceanic Methane Interdisciplinary Meeting in Brest
Methane is the simplest organic molecule, yet it has a profound impact on Earth’s climate and represents a dynamic component of the oceanic carbon cycle. This cycle is partly shaped by interactions between the geosphere -the largest methane reservoir- and the ocean, where methane distributions are highly variable and constitute a natural source to the atmosphere.
The oceanic methane cycle is governed by processes operating across multiple spatial and temporal scales. These include large-scale geological drivers such as sediment deposition, tectonic activity, and gas hydrate dynamics, as well as fine-scale biological and chemical transformations. The latter encompasses biologically mediated methane production and consumption through multiple pathways across a wide range of environments, from anoxic sediments to the oxic water column (the so-called “methane paradox”), as well as abiotic methane production associated with hydrothermal vent systems. Rapidly evolving technologies, particularly advances in methane sensors, isotopic techniques, and omics approaches, now offer unprecedented opportunities to observe, quantify, and constrain methane dynamics in the ocean.
Advancing our understanding of the oceanic methane cycle requires a broad and truly interdisciplinary approach, integrating expertise from microbiology and ecology, geology and geophysics, geochemistry and biogeochemistry, Earth system modeling, analytical chemistry, and sensor development. To foster interdisciplinary exchange and collaboration in oceanic methane research, we propose to host a three-day scientific meeting in Brest, preceded by a one-day pedagogical event dedicated to students and early-career scientists. Registration is free and includes coffee breaks and lunch. The MethanOcean meeting is organised by:

Methane production processes in oxic waters and sea-to-air fluxes
Invited speaker
Dr. Mina Bizic | TU Berlin
More information
The global flux of oceanic methane to the atmosphere is unsurprisingly dominated by highly-productive shallow coastal environments, where methane is the product of methanogenesis in anoxic conditions. But methane oversaturation is also observed in most oxic ocean surface waters, including well-mixed coastal waters, a phenomenon known as the ‘ocean methane paradox’ (OMP). This session welcomes contributions on the comprehension of methane anomalies in the oceanic euphotic layer and on the estimation of sea-to-air fluxes in offshore environments via in situ measurements and/or modelling. The aim is not only to uncover the dynamics and processes driving the oceanic methane cycle but also to determine how the oceanographic community can contribute to the evaluation of methane fluxes through e.g. systematic measurements of methane during oceanographic cruises or the development of long-term high frequency observatories.

Marine methane microbial and macro-ecology: from molecules to ecosystems
Invited speaker
Dr. Gunter Wegener | MARUM
More information
This session focuses on the microbial and macrofaunal ecology in marine environments, from the molecular mechanisms of methanogenesis and methane oxidation to their impacts on chemosynthetic ecosystems in sediments and water column. We welcome contributions integrating cultivation-based experiments, omics approaches, stable isotope probing, and biogeochemical analyses to elucidate the diversity, activity, and interactions of methane-cycling micro and associated fauna. Particular emphasis will be placed on studies linking microbial processes to ecosystem-scale methane dynamics, including sediment-water exchanges and benthic-pelagic coupling. This session aims to highlight the central role of organisms in controlling methane transformations and shaping the chemical and functional properties of marine ecosystems.

Marine geology and geophysics: from deep structures to surface processes
Invited speaker
Dr. Aurélien GAY | Univ. Montpellier
More information
Assessing the significance of marine gas sources to the global methane budget relies on the upscaling of local observations supported by the regional understanding of the geological and geomechanical factors controlling the accumulation and migration of free gas in the subsurface. This session aims at covering these interrelated topics with particular emphasis on quantitative ground modelling and numerical simulation of gas charging and flow. Contributions dealing with advances in geophysical methods for the detection and quantification of free gas in sediment and in the water column are welcome as well as field scale analyses of coupled flow and geomechanics.
June 10, 2026, afternoon PNBI
Biogeochemistry across geosphere-ocean interface
Invited speaker
Dr. Eoghan Reeves | UiB
More information
The geosphere contains the largest methane reservoirs, produced through microbial, thermogenic, and/or abiotic processes. We welcome studies aimed at distinguishing and quantifying the various methane production pathways in the subsurface, from abiotic to biotic processes, as well as processes that can occur at interfaces (such as mixing, diffusion, and degradation) during migration through the geosphere and eventual release into the ocean. These investigations are essential for constraining methane dynamics and assessing their impacts on oceanic systems.
