The European Geosciences Union (EGU) is currently accepting abstract submissions for the EGU General Assembly 2019. This meeting will convene 7-12 April 2019 in Vienna, Austria.

Conveners of the following two sessions invite abstract submissions:

SESSION CL1.25: Polar Continental Margins and Fjords – Climate, Oceanography, Tectonics, and Geohazards
Conveners: Michele Rebesco, Matthias Forwick, H. Christian Hass, Berit Oline Hjelstuen, and Jan Sverre Laberg

During the last decade significant advances in our understanding of the development of Cenozoic polar continental margins have been made. 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. Results have been obtained from conventional and high-resolution 2D and 3D seismic surveying, as well as from short sediment cores and longer drill cores. Fjords are regarded as “small oceans” that incise high latitude coastlines and link continental margins with the interiors of landmasses. Fjord settings allow us to study a variety of geological processes similar to those that have occurred on glaciated continental margins, but typically at smaller scales. The contribution of several sediment sources (e.g. glacial, fluvioglacial, fluvial, and biological) to fjord basins along with relatively high sedimentation rates also provides the potential for high-resolution palaeoclimatic and palaeooceanographic records on decadal to centennial timescales. The aim of this multidisciplinary session is to follow on from the success of previous years by bringing together researchers working on northern and southern high-latitude continental margins and fjords, investigating the dynamics of past ice sheets, climate, tectonics, sedimentary processes, physical oceanography, and palaeo-biology/ecology.

Invited Keynote Speakers include:

  • Julia Wellner, University of Houston: Preliminary results from IODP Expedition 379 (Amundsen Sea West Antarctic Ice Sheet History), and
  • Patrick Lajeunesse, Université Laval: Late-Wisconsinan Paleoglaciology of the Western Gulf of St. Lawrence and Adjoining Areas.

SESSION BG1.6: Nitrogen-transformation Processes in Terrestrial and Aquatic Ecosystems under Global Change
Conveners: Tuula Larmola, Sari Juutinen, and Sami Ullah

Anthropogenic disturbance of the nitrogen (N) cycle has more than doubled the amount of reactive N circulating in the biosphere. Global change impacts the N cycle via increased levels of N deposition, land use, and changes in global or regional climate. This session seeks to improve our understanding on how global changes impact N biogeochemistry in terrestrial and aquatic ecosystems and what feedbacks from N cycling will be most important in influencing the climate. Conveners invite presentations on all aspects of ecosystem N cycling, past and present ecosystem dynamics and functioning, interactions with other element cycles (e.g. carbon, phosphorus), terrestrial-aquatic linkages, future projections, and feedbacks to global change (e.g. increased greenhouse gas emissions, biodiversity loss, air and water pollution). Conveners welcome contributions using observational, experimental, and modeling approaches from local to global scales and varying in time-horizons.
