Dear colleagues,
This is a 2nd reminder that we would like to invite you for submitting an abstract to our session CL1.16 "Polar continental margins and fjords - climate, oceanography, tectonics and geohazards" at the EGU General Assembly 2020 in Vienna, Austria (3-8 May).
Abstract:
Significant advances in our understanding of the development of Cenozoic polar continental margins have been made over the last two decades by studying continental shelf and slope sediment sequences. These include more 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, as well as from a growing number of short sediment cores and 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 continental margins to fjords, to provide a multi-disciplinary picture of polar areas. We welcome submissions focussing on (but not limited to) records of past climatic change, tectonics, oceanography and ecosystems, and the associated links with ice sheets and glacier behaviour, ice-ocean interactions and glacial-marine sedimentary processes. Studies that integrate different datasets, data types, or that marry observations with numerical modeling are also encouraged.
The deadline for abstract submissions is approaching quickly: 15 January 2020, 13:00 CET.
