Organizers are accepting session abstracts for the virtual European Geosciences Union General Assembly 2021 (vEGU 2021). This conference will be held online 19-30 April 2021.
Conveners of the following session invite abstracts:
CL4.25: Polar Regions – Climate, Oceanography, Tectonics, and Geohazards
Conveners: Andrew Christ, Johann Philipp Klages, Kelly Hogan, Kasia K. Sliwinska, and Michele Rebesco
Significant advances in understanding of the Meso- and Cenozoic development of polar regions have been made over the last two decades by studying continental shelf, slope, or deep-sea sediment sequences. These include detailed reconstructions of the climatic, oceanographic, and tectonic evolution of high northern and southern latitudes over various time scales, as well as reconstructions of past ice-sheet dynamics and studies of marine geohazards. Data have been obtained from conventional and high-resolution 2D and 3D seismic surveying, from a growing number of short sediment cores, and from targeted high-latitude deep drilling expeditions (e.g. IODP, MeBO). The same techniques have also been applied in fjords, which link the continental margins with the interiors of landmasses and act as “miniature ocean basins”. Fjord settings allow us to study similar geological processes to those that acted on glaciated continental margins but at smaller scales. The variety of sediment inputs (e.g. glacial, fluvioglacial, fluvial, biological) to fjord basins along with relatively high sedimentation rates provides the potential for high-resolution palaeoclimatic and palaeooceanographic records on decadal to centennial timescales.
The aim of this session is to bring together researchers working on both northern and southern high latitudes processes spanning various spatio-temporal scales from fjords to the deep sea, to provide a multi-disciplinary picture of polar regions. Conveners welcome submissions focusing on (but not limited to) records of past climatic change, tectonics, oceanography and ecosystems, and the associated links with ice sheets and glacier behavior, ice-ocean interactions, and glacial-marine sedimentary processes. Studies that integrate different datasets, data types, or that marry observations with numerical modelling are also encouraged.
Conveners dedicate this session to their dear colleague and co-convener, Christian Hass, whose enthusiasm and knowledge helped shape this session over many years.
