Extreme processes shaping coastal landscapes in rapidly deglaciating Arctic

to be presented by:

Prof. Dr. Mateusz C. Strzelecki

Alfred Jahn Cold Regions Research Centre, Institute of Geography and Regional Development, University of Wroclaw, Poland

 

Abstract

The observed acceleration of Arctic coastal change is mostly associated with a decreasing sea ice extent and duration that increases shoreline exposure to storm wave energy and erosion. Loss of sea ice is only one of the processes that transform Arctic coastal zone. The functioning of the present‐day Arctic coastal system is also influenced by permafrost degradation, storm‐surge floodings or increased sediment supply from river catchments. Majority of those changes have a strong impact on circum‐polar Arctic coastal communities and their historical (including heritage) and modern infrastructure. Compared with recent research advances obtained along ice-rich permafrost sections of the Alaskan, Yukon and Siberian coastlines, less work has been done on the coastal environments of High Arctic archipelagos including Svalbard, Novaya Zemlya, Franz Joseph Land, the Canadian Arctic Archipelago and Greenland. Probably the key important feature distinguishing these environments is the strong and combined imprint of previous continental glaciations and modern glacial activity on coastal morphodynamics, which classifies these coasts as paraglacial. Set against this context, the overarching aim of my talk will be to characterise the response of a coastal systems, developing in Svalbard and Greenland, to post‐LIA climatic conditions that were characterised by enhanced paraglacial processes, in turn triggered by rapid deglaciation.

 

 

InterRidge 2022 Webinar November 

Dr. Marcia Maia (CNRS Senior Researcher at Laboratoire Geo-Ocean, CNRS-UBO-IFREMER-UBS, France) will have the InterRidge Webinar on Wednesday. You can find the detail below. Please Join us for the webinar and enjoy the discussion. Her lecture will be uploaded online. 
 
Evolution and intra-transform spreading processes of the St. Paul transform system, Equatorial Atlantic
Dr. Marcia Maia (CNRS Senior Researcher at Laboratoire Geo-Ocean, CNRS-UBO-IFREMER-UBS, France) 
Day and time: 11:00 GMT (12:00 CET), Wednesday, 30th November 2022
Meeting ID: 965 2496 6368
Passcode: 521561
 
Summary
Oceanic transform faults are among the less well-known features of the ocean floor. In the recent years,much has been done to understand their thermo-mechanical structure and thedeformation associated with local and far field stresses. Among these features, complex multi-fault systems, where very short spreading segments are offset by large transform faults, are most interesting, especially those atslow spreading ridges, where transform faults are supposed to be cold geological settings. Studying such systems can bring new information on the relative roles of the mantle and the lithosphere on the spreading processes and on the origin and evolution of large offset transform faults. Here, I will present work done on the multi-fault system of St. Paul in the slow spreading Equatorial Mid-Atlantic ridge. The evolution of such intra-transform spreading systems raises the question of how cold transform faults are and of their effect on the spreading processes. 
 
Main Points 
1. Deformation along oceanic transform faults is controlled by kinematic changes and by local processes, including the nature of the underlying mantle.
2. Oceanic transform faults may not be as cold as previously supposed.
3. Intra-transform spreading processes are mainly controlled by the nature of the mantle.
 
Biography
After a PhD at Université Paris-Sud, Orsay, I joined the Marine Geosciences group at Université de Brest as a CNRS researcher. My research topics are mainly on mid-oceanic ridge processes, their interactions with mantle plumes and, more recently, oceanic transform faults and fracture zones. I also do research on deep sea instrumentation and am working on a gravity sensor for AUVs. 
 

Feminine image of the sea

The Institute of Oceanology of the Polish Academy of Sciences and Art Inkubator in Sopot present the event
"Feminine Image of the Sea"

A nationwide competition addressed in 2022 to women, students and graduates of art universities (Academies of Fine Arts and Universities) and faculties with artistic profiles of other universities in Poland and professional artists dealing with art professionally.
The competition was aimed at raising maritime awareness and promoting it through art. We want to present the female point of view of maritime themes, both from the scientific and artistic side. Selected competition entries will form an exhibition at the conference inaugurating the MARBEFES project.


The artists made works inspired by the issues presented by the researchers of the Institute of Oceanology of the Polish Academy of Sciences in Sopot.

ECOP Wednesday event series

Join us on the first Wednesday of every month for an ECOP event series that digs into the European marine science policy landscape!

The EMB ECOP Network was initiated in March 2022 by the EMB Young Ambassadors and the EMB Secretariat. It is designed to bring together Early Career Ocean Professionals (ECOPs) who are linked to the EMB Member Organizations, and provide them with a platform to meet, interact, learn, and have a voice.

The ECOP Wednesday event series is aimed specifically at the EMB ECOP Network, and focuses on the European and international marine science policy landscape. Held over lunch on the first Wednesday of every month, these one hour online events give attendees a chance to learn more about this complex landscape and interact with research and policy professionals and other stakeholders working within it.

The ECOP Wednesdays series provides members of this network with an opportunity to learn more about the wider context of their own research, and about different aspects of the European and international marine science policy. It is also an opportunity to connect with others who have an interest in this field. This monthly online event series is free of charge. The events include speakers working within different fields of marine science policy, and attendees will have an opportunity to ask questions and engage in discussion. These events will also bring opportunities to discuss and debate on the present state and future of this landscape.

The upcoming ECOP Wednesdays will take place on the dates listed below. You click on the link to find out more information about the topic and speakers, as well as register for the event:

 - Wednesday 7 December 2022: Thoughts on the future regulation of ocean observing in the European Union

We invite you warmly to join a second presentation this winter semester of the Szczecin Marginal Seas Webinars series

for the Webinar to be held on November 17, 2022, 2:00 pm (CET).


Please, join our online meeting for the lecture:

Postglacial sea-level change and shoreline development in SE Africa: implications for past and present human populations

to be presented by:

Prof. Dr. Andrew Cooper

School of Geography and Environmental Sciences, Ulster University, UK

Abstract

The relationship between sea-level change and shoreline response is complex and is governed, amongst other things, by the rate of sea-level change, sediment supply/volume and antecedent topography.  The nature of the shoreline and its response to changing sea level have important implications for human societies in the past and in the present.

In SE Africa, sea level has changed over a vertical range of >130 m since the last interglacial.  The  course of sea level change is reflected in the development and preservation of shoreline deposits that are preserved on the narrow continental shelf and along the modern shoreline.  Shoreline morphology shows marked differences at different sea-level stages and these mainly reflect variations in geological setting.  The preservation of shorelines is linked to alternating periods of slow and fast sea-level rise and they occur at predictable elevations and time periods.  These observations have the potential to inform prediction of future shoreline position.

The changing nature and position of the shoreline has influenced its exploitation by humans and various forms of evidence of human utilisation are preserved.  In the Anthropocene, threats to human interests from changes in shoreline position are reciprocated by threats to shoreline integrity via human interventions.

The meeting room will be open from 1:30 pm (CET), but the seminar will begin at 2:00 pm (CET).
