Biogeochemistry conferences

The meeting examines disputed and unresolved questions about rapidly changing Arctic and Southern oceans. It brings circulation, ecology and biogeochemistry together to consider sea-ice loss, freshwater inputs, deep-water formation, primary production and climate-active aerosols. Sessions emphasize why these processes remain difficult to measure and explain, including feedbacks on planetary reflectivity and atmospheric composition. Comparisons with ancient ice-covered oceans and oceans on other worlds broaden the discussion. Attendance requires a bachelor’s degree in science or engineering, or an accepted equivalent. Applications are subject to selection and available capacity.

The meeting connects ecology, hydrology, geochemistry, soil science and Earth-system modelling to explain how catchments function across boundaries. Researchers will compare findings across biogeoclimatic regions, disciplinary approaches, and spatial and temporal scales, with particular attention to interfaces between systems. Experimental studies, laboratory analyses, modelling and synthesis of observations will be used to identify advances that become visible when these approaches are combined. Attendance applications are reviewed and capacity may fill before the application deadline.

The conference organizes ocean chemistry around inventories, exchange rates and reaction mechanisms. It considers carbon, nutrients, trace elements and organic compounds in seawater, sediments and coastal margins, connecting molecular processes with basin-scale transport. Researchers will discuss autonomous measurements, isotope and molecular methods, long observational records, and the challenges that ocean change and proposed interventions pose for assumptions of steady state. Attendance requires a bachelor’s degree in science or engineering, or an accepted equivalent. Applications are subject to selection and available capacity.

Organized by the M-FED27 Organising Committee, the conference examines microbial deposits from modern environments to the deep geological record. It combines sedimentology, geomicrobiology, geochemistry, mineralogy and petrology across field, laboratory and molecular scales. Contributions address how microbialites form and change, methods for studying them and environmental applications. Talks and posters are supplemented by workshops and optional field excursions; reduced prices support early-career participation.
