GSA Penrose Conference: CLAST2019, 4-10 August 2019, Juneau, Alaska

GSA Penrose Conference: CLAST2019, 4-10 August 2019, Juneau, Alaska

We are happy to announce the GSA Penrose Conference on Climatic controls on continental erosion and sediment transport (CLAST2019), 4-10 August 2019, Juneau, Alaska (USA).

Key challenges remain in recognizing and reconciling how climatic and earth surface process mediate erosion independently of solid earth forcing. The relationship amongst climatic, erosional, and transport processes are exceedingly complex and arguably more intricate than those typically defined between erosion and tectonics. However, the study of these relationships is fundamentally problematic because many of these processes act both independently of and as a consequence of solid earth forcing. This conference seeks to discuss how climate can mediate the sedimentary record and under what conditions erosional signals can be observed and interpreted unambiguously in terms of paleoenvironmental and paleoclimatic change? Global Cenozoic climate, fluctuating sea level, and large-scale glaciation have pivotally affected our planet, from the physical evolution of mountain belts to the chemical breakdown of sediments distributed across margins. How do longer- and shorter-term climatic phenomena dictate rates of sediment supply and records of provenance? To what extent do environmental conditions mediate the periodic storage of sediments? Climatic control over sediment transport certainly extends to the offshore, so how do earth surface processes dictate the supply, loading, and stratigraphic architecture along margins and into the deep sea? And, under what conditions and timescales can precise and accurate climatic records be reconstructed from sediments?

This conference particularly solicits contributions addressing erosion and/or environmental change from all earth surface process disciplines that permit robust correlation between changes in climate, erosion, and sediment transport. Separating drivers and processes continues to be difficult but are much improved in recent years as field studies are coupled with novel spatial and temporal control and further tested with dynamic landscape and stratigraphic models. This transdisciplinary meeting is intended bring together researchers across fields to showcase the current state of research, demonstrate contemporary evidence and methods from studies worldwide, and underline the research concerns remaining in our community.

Dates: 4-10 August 2019

Venue: Juneau, Alaska, USA

This seven-day meeting will start with an icebreaker in the evening of Sunday, 4 August 2019 in the city of Juneau, nestled within the Coast Mountains of southeast Alaska. It will end in fjordland, at the feet of Tracy Arm tidewater glaciers on the afternoon of Saturday, 10 August 2019. The meeting will balance between invited talks, roundtable discussions, pop-ups, and poster presentations, with two field trips occurring mid-week and on the last day.

Attendees and Estimate Costs

Registration fee is estimated at US$950-$1050 and will cover the cost of the meeting, hotel lodging for six nights, icebreaker reception, all lunches, coffee breaks, and poster refreshments, the mid-meeting conference dinner, and transportation and meals for the first field trip. The second field trip is optional; this cost is not included in registration and will be determined at a later date based on number of interested participants. Airfare is not included and participants must make their own travel arrangements.

Applications and Registration

Application period opens: 1 March 2019
Application deadline: 1 May 2019
Registration deadline: 7 June 2019

ECS Events @EGU2018

Finally, the EGU general assembly is starting today. In order to give you some guidance what important events you should definitely not be missing out on, the ECS representatives (Micha Dietze and Annegret Larsen) put together this very nice timetable:

Time to travel – the ERASMUS program turns 30 this year

Time to travel – the ERASMUS program turns 30 this year

The mobility program of the European Union, named after Erasmus of Rotterdam who studied in different places all over Europe, turns 30 this year. I wanted to take this opportunity to promote this great possibility for gathering international experience and getting insights into the teaching and research skills of our European colleagues.

The ERASMUS program, named ERASMUS+ since 2014, is most famous for providing scholarships for students, and that is what this backronym originally stands for: European region action scheme for the mobility of university students (ERASMUS). But over the years, the program has been growing, since 1997 also funding the mobility of University staff between institutions. Since then, roughly half a million staff exchanges were funded. Every European University that takes part in the ERASMUS program has bilateral agreements for the mutual exchange of students and staff. And the big advantage of the ERASMUS staff exchange program is that it is very easy to organize: Find out which institution your university has an agreement with, contact a colleague there, sign a mobility agreement and plan your trip. The financial support is really well calculated: Depending on which country you are visiting you will receive a dayly lump sum of 100-160 Euro for living expenses and of course travel costs depending on distance (e.g. 500-2000km = 275 Euro).

Our department at Bonn University for example has 34 partner institutions all over Europe, and with ERASMUS+ there is also the possibility to expand these collaborations to non-EU countries worldwide. This year, we received Tomas Galia from the University of Ostrava (Czech Republic) here in Bonn to share his research findings on woody debris in mountain channels in the Carpathian Mountains and I went to the University of Vienna (Austria) to give a field course on UAV applications in geomorphology together with Sabine Kraushaar. So, take advantage of this opportunity and get to know other departments and offer joint courses with your colleagues and maybe also advance other projects during that shared time.

ESURF – Special Issue on 4-D reconstruction of earth surface processes

Special Issue in “Earth Surface Dynamics” (interactive, open-access and public peer reviewed journal): 4-D reconstruction of earth surface processes: multi-temporal and multi-spatial high resolution topography.

The special issue aims to demonstrate the advantages of High Resolution Topography (HiRT) to measure and understand earth surface processes at multiple temporal scales and varying spatial resolutions. The focus is on how HiRT data enhances and supports geomorphic process understanding, thereby demonstrating its capability to capture and monitor earth surface processes at unprecedented scales and, consequently, to provide new insights into how landscapes evolve in relation to forces of variable frequency and magnitude.
