Zaproszenie do składania wniosków dla rozwijającego karierę naukowca do Komitetu Wykonawczego SCOR

The 2022 call for applications for an Early-Career Scientist (ECS) to join the SCOR Executive Committee is open. The ECS in the SCOR Executive Committee will help reaching out to the broader early-career community and get it involved into SCOR activities.

Position Description: The early-career scientist will have the same responsibilities as other SCOR Executive Committee members (see https://scor-int.org/scor/about/officers/job-descriptions/) with a term of appointment of two years to start in October 2022.

Requirements: Applicants should be no more than 10 years from PhD not counting time for family leaves, and should be affiliated to an ocean science organization, institution, or government agency. Applicants should have good communication skills in English, both speaking and writing. Candidates from developing countries are encouraged to apply.

More information about the position and application instructions can be found here.

Deadline for submission of applications: 26 August 2022.

Please email the completed application form and requested documents to the SCOR Secretariat (Ten adres pocztowy jest chroniony przed spamowaniem. Aby go zobaczyć, konieczne jest włączenie w przeglądarce obsługi JavaScript.).

Konferencja: Climate Change: Science & Society

Zaproszenie

Piąta edycja konferencji Polish Scientific Networks (https://psn.cs.put.poznan.pl/psn/) pt. Climate Change: Science & Society (28-30 września 2022 we Wrocławiu) poświęcona jest przyczynom i skutkom zmian klimatycznych. Zgromadzi czołowych polskich badaczy zmian klimatycznych i ekspertów z całego świata, którzy będą debatować nad tym jak lepiej zrozumieć wpływ klimatu na światowe środowiska i społeczeństwa oraz jak na nie reagować.

Chcielibyśmy zwrócić Państwa uwagę na sesję związaną ze zmianami klimatycznymi i oceanami. Prosimy o przesyłanie abstraktów do 30 czerwca 2022 r.

Webinar: Deciphering  the ocean magnetic stripes: the signal and the recorder 

InterRidge 2022 Webinar June
 
Dr. Jérôme Dyment  (Senior Researcher, Université Paris Cité, Institut de physique du globe de Paris, CNRS)
08:00 GMT (10:00 CEST), Tuesday, June 28, 2022
Meeting ID: 915 0817 5439
Passcode: 251400
  
Summary
Marine magnetics have been essential in leading the geoscience community to adopt Plate Tectonics as the new paradigm of Earth Sciences  in the 1960s. Despite their wide use to date, understand the structure and reconstruct the past evolution of ocean basins, marine magnetic anomalies still have the potential to tell us more about the recorded signal - the main geomagnetic field history of the last 160 Ma - and the recorder - the oceanic crust and possibly the uppermost mantle. We will revisit both aspects in the light of recent works in various tectonic contexts - mid-ocean ridges, oceanic basins, subduction zones and passive margins - to derive a consistent picture of the magnetic structure of the oceanic lithosphere at different steps of its evolution. We will show that mastering both aspects - the recorder and the signal - are essential to properly date the seafloor, with examples from Meso-America, and will insist on the importance of collecting new well-navigated magnetic profiles to supersede those acquired before satellite positioning and increase the resolution of plate reconstructions.
  
Main points
1. Marine magnetic anomalies are still not used at their full potential - they contain a lot more info than dating  the oceanic lithosphere.
2. A first info is on the recorded signal, the main geomagnetic field history of the last 160 Ma, both in polarity and in intensity.
3. A second info is on the recorder, the magnetic structure of the oceanic crust in different contexts, from its creation at mid-ocean ridges to its destruction in subduction zones. 
4. Underway magnetic data should still be collected, if only to replace pre-GPS data for accurate plate reconstructions.
 
Biography
 
Dr. Jérôme Dyment is CNRS Senior scientist at Institut de Physique du Globe de Paris, France. His research interest focuseson marine magnetic anomalies, to 1) date and reconstruct  the structure and evolution of ocean basins, 2) depict the structure and magnetic properties of the oceanic lithosphere and understand active processes at mid-ocean ridges, and 3) refine the history of the geomagnetic field to constrainits mechanisms. Holding an Engineer Degree and a PhD in Geophysics (Strasbourg, resp. 1987 and 1991), he is the author of more than 90 scientific publications, supervised 10 PhD theses, participated 20 scientific  cruises (9 as chief scientist), and is or was PI of French and bilateral scientific projects with, for the most recent ones, India, Mauritius, Japan, Korea, and Indonesia. Among various community tasks, he has been the advisor of CNRS Director for marine geosciences (2006-2011), the president of the French committee associated to the International Union of Geodesy and Geophysics (2010-2014), the head of the Marine Geoscience Team of Institut de Physique du Globe de Paris (2013-2016), and Steering Committee member (2001-2010) and the chair (2016-2020) of InterRidge.  He is also leading the Task Force appointed by the International Association of Geomagnetism and Aeronomy to build the World Digital Magnetic Anomaly Map.
