This lecture has been presented each year since 1981 and is one of the principal events in the British Geophysical Association calendar. The Bullerwell lecture, named after the first Chief Geophysicist of the British Geological Survey, is a prestigious event that has been given by many of those UK geophysicists who are major international Earth Scientists, receiving honours from a wide range of learned societies, academic and governmental institutions. This year's lecturer is Dr. Tim Craig.

Since 2006, the German Geophysical Society (DGG) promotes the C.F. Gauss Lecture within the frame of the General Assembly of the European Geosciences Union (EGU). Selected authors give an in-depth overview on a specific field of geophysics.

The Copernicus Medal Ceremony 2022 will honour the Copernicus Medallists of 2020 and 2022. Each medallist will give a 30-minute medal lecture.

The Copernicus Medal 2020 has been awarded to Justin C. Kasper, University of Michigan's Climate and Space Sciences and Engineering Department, for his pioneering work on the heating and acceleration of the solar corona and the solar wind, and his outstanding leadership of the SWEAP Investigation on Parker Solar Probe which has now successfully touched the Sun.

The Copernicus Medal 2022 has been awarded to Athanasios Nenes, Laboratory of Atmospheric Processes and their Impacts (LAPI) at the École Polytechnique Fédérale de Lausanne, for transformative contributions and fundamental advances at the interface of aerosol science with cloud formation, air quality, biogeochemical cycles and climate through a combination of theory, instrument development, measurements, and modelling.

Landslides, such as rockslides, rockfalls, and debris flows, have been occurring extensively in a large number of countries, typically Asian countries, causing heavy damage. Landslides have been studied in various research fields, such as geomorphology, geology, geophysics, Sabo engineering, geotechnics, but we need a common platform to exchange research results and make discussion to strengthen our activity. This session is such a place and we invite contributions that report and discuss on landslides and related phenomena, focusing on improved understanding of their characteristics; new insights into landslide mechanisms; the development of new approaches to monitoring; novel approaches to behavior forecasting and prediction; studies of successful landslide management; and the development of methods for hazard and risk evaluation.

Recent technical developments have enabled us to acquire high-definition topographic and geophysical data for geoscientific research, including land surface processes, subsurface structures, submarine/aerial environments, and geo-ecological interactions. Such high-definition or high-resolution data are particularly useful for studies on landscape developments in a relatively short-term (decadal to millennial time scales), which are often assessed with a concept of connectivity in spatial and temporal contexts. In this session, we expect submissions on topics challenging the issues of connectivity in the Anthropocene, the most recent geological era of the Earth affected by human activities. A range of topics would fit the session framework, including theoretical works, data acquisition, pre- and post-processing, extensive data preservation and archiving, statistical analysis, physical modeling, machine learning, and numerical simulation. The methodological approaches may include, but are not limited to, laser scanning (Lidar), photogrammetry (SfM), GNSS precise positioning, SAR interferometry, multi-beam sonar, ground-penetrating radar, geomagnetic/electromagnetic sensors, and multi/hyperspectral sensors, based on terrestrial (fixed or mobile), aerial (UAV or manned airborne), or satellite platforms.

Volatiles play an important role in the dynamical and chemical processes in the Earth. The presence of volatiles drastically changes mineral stability and rheological behavior of the rocks. Chemical fractionation, such as partial melting, hydration, and dehydration are controlled by volatiles in the rocks. Volatiles enhance the production of magmas and drive their ascent and volcanic eruption. The atmosphere and hydrosphere have been generated by variety of degassing events from the mantle through volcanism. Some volatiles in the Earth's surface have been suggested to be recycled back into the mantle beyond subduction zones. Although the significance of volatiles in the Earth's evolution has been recognized, each of these processes is poorly constrained. We therefore welcome contributions from experimental, observational, and modeling studies that help shed light on the behavior, chemical/physical characteristic, and flux/budget of volatiles, such as hydrogen, carbon, nitrogen, noble gases, halogens, and sulfur. We encourage studies linking the behavior of multiple volatile elements and their isotopic compositions. Studies investigating the linkage between volatile and solid geochemical tracers, the phase equilibria of volatile-bearing mantle assemblages, and the effect of volatiles on the physical properties of the mantle are also welcome.

In order to reconstruct the Earth climate system, marine paleoclimatologists resort to transfer functions or geochemical proxies, which are produced or affected by organisms. The relationships used for reconstructions are generally based on field calibrations or derived from laboratory experiments. The danger of these so-called empirical relationships is that they may be valid only within the restricted parameter space of their calibration. Application of proxy relationships to very different environmental settings (e.g. high vs. low latitude or glacial vs. interglacial) requires a mechanistic understanding of these relationships. Much progress can be expected by a better understanding of the biomineralization mechanisms and the incorporation of proxy signals. In this session we facilitate contributions related to the biomineralization, calibration and validation of marine proxies from field study, laboratory culture experiment, biological & ecological studies and paleo-environmental reconstruction.

Cultural heritage (World Heritage Sites, historical structures, archaeological artifacts, etc.) and geoheritage (geosites, geoparks, etc.) are exposed to weathering in the geological and human time scale. The resulting deterioration of the rocks and other geological materials in cultural and natural contexts can be often severe and demands the prompt adoption of conservation measures. The relevant research involves a range of disciplines: mineralogy, geomorphology, geoarchaeology, environmental science, engineering geology, materials science, analytical chemistry, etc. However, our knowledge on many aspects is still limited. This session welcomes contributions presenting original research, case studies, and discussions on damage assessment, experimental techniques, monitoring, predictive models, conservation procedures, documentation, etc., related to geological materials in cultural heritage and geosites.
