Talk by Benoit Lecavaliers @Bergen @ Undervisningsrom 4020 in 4th floor, West Wing GFI.
Jun 1 @ 15:00

Hei hei everyone!

We have the pleasure of inviting you all to Benoit Lecavaliers talk this Thursday (June 1st) at 15:00 in the  Undervisningsrom4020 in 4th floor, West Wing GFI. The talk will be on his newest paper published last week with the title “A high Arctic Holocene temperature record and Greenland ice sheet evolution “. For those of you who haven’t met Benoit yet, he’s a visiting PhD student from Memorial University, St. John’s, Canada until mid June, at the moment located in the top floor in the West Wing.

Cheers,

Silje and Kerim

Abstract:
We present a revised and extended high Arctic air temperature reconstruction from a single proxy that spans the past ~12,000 years (up to 2009 CE). Our new reconstruction from the Agassiz ice cap (Ellesmere Island, Canada) indicates an earlier and warmer Holocene Thermal Maximum with early Holocene temperatures that are 4-5 oC warmer compared to a previous reconstruction and regularly exceed contemporary values for a period of ~3,000 years. Our results show that air temperatures in this region are now at their warmest in the past 6,800–7,800 years and that the recent rate of temperature change is unprecedented over the entire Holocene. The warmer early Holocene inferred from the Agassiz ice core leads to an estimated ~1 km of ice thinning in Northwest Greenland during the early Holocene using the Camp Century ice core. Ice modeling results show that this large thinning is consistent with our new air temperature reconstruction. The modeling results also demonstrate the broader significance of the enhanced warming, with a retreat of the northern ice margin behind its present position in the mid Holocene and a ~25% increase in total Greenland ice sheet mass loss (~1.4 m sea-level equivalent) during the last deglaciation, both of which have implications for interpreting geodetic measurements of land uplift and gravity changes in northern Greenland.

2017 Advanced Climate Dynamics Course (ACDC) @ Bonne Bay Research Station on Newfoundland
Sep 11 – Sep 22 all-day

ACDC 2017

Topic: The Dynamics of the Seasonal Cycle

Date: September 11th – 22nd, 2017

Location: Rondvassbu, Rondane National Park, Norway

Application deadline: 10th of March, 2017

Online application form: HERE

Target: Advanced PhD candidates and early career scientists.

Goal: To mix students and lecturers with empirical and dynamical training within
climate science and focus on understanding the basic principles and dynamics of the
seasonal cycle across different timescales. This summer we will explore what we can
learn from the largest reoccurring change in Earth´s climate.

Confirmed lecturers: Peter Huybers (Harvard), David Battisti (University of
Washington), Camille Li (UiB), Jake Gebbie (WHOI), Patrick Heimbach (UTexas/MIT),
Kerim H. Nisancioglu (UiB/UiO), Øyvind Paasche (UiB), Tore Furevik (UiB).

Workshop Modeling Meltwater in Snow and Firn: Processes, Validation, Intercomparison and Model uses of Optical Remotely Sensed Data @ Geological Survey of Denmark and Greenland (GEUS)
Sep 20 @ 12:00 – Sep 22 @ 12:00
20-22 September 2017, Copenhagen.
  • The workshop starts Wednesday Sep 20 at 12.00, and ends Friday Sep 22 at 12.00.
  • A PROMICE 10-year jubilee and reception is planned for the afternoon of Sep 22.
Purpose
  • to present and discuss results on modeling of meltwater retention processes in snow and firn on ice sheets and glaciers;
  • to plan and coordinate meltwater retention model development;
  • to emphasize optical remote sensing snow parameter data comparison and data assimilation;
  • to formulate a protocol for a meltwater retention model intercomparison project (RetMIP)
 
Sessions
  • Snow model development
  • Meltwater retention model validation
  • Meltwater retention model intercomparison project (RetMIP)
  • Optical remote sensing to improve snow models
Session 1 welcomes, for example, model considerations of water availability vs. percolation rate vs. refreezing rate to explore the importance of heterogeneous percolation modelling in polar firn; fine-and-local scale/detailed modeling with possible suggestions to including bulk effects in larger-scale models; inclusion of piping (for instance, by “skipping layers” during percolation) in distributed or single-column models; inclusion of horizontal water motion in snow and firn, i.e. between grid cells.
 
Session 2 will focus on discussions of useful model validation metrics and aim to compile observational datasets that may be used to validate the above processes.
 
Session 3 will discuss and formulate a protocol for a meltwater retention model intercomparison project.
 
Session 4 serves an ESA Sentinel-3 for Science Land Study: Snow “S-3-Snow” that includes an element to gather and prioritize snow modeller interest and requirements about optical remotely sensed snow parameters (snow extent, albedo, grain size, impurity content, etc.). The ESA study is to engage users of Sentinel-3 snow optical retrievals in 1.) model comparison and/or 2.) data assimilation. The workshop session is to:
  • survey and prioritize remotely sensed snow parameter data users’ requirements for global and regional snow information
  • discuss how to enhance methods for estimating snow parameters, either from remote sensing or from modeling, and to evaluate advantages and disadvantages of the different approaches
  • consult users about the utility/interest in other snow products suitable for studying climate-related issues.
 Workshop expected outcomes
