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.

ICAT PhD school 2017 @ University of Copenhagen
Sep 25 – Sep 30 all-day

ICAT PhD school 2017

Week 39 -2017

Scope and participation:

The PhD course is aimed at PhD students and junior postdocs who conduct ice core analysis or are users of ice core data (glaciological, oceanographic, climate modelers).

The results from ice cores cannot be fully appreciated without understanding the analytical techniques behind the measurements as well as the implicit assumptions related to the emission, transport and deposition of the species analysed.

These include a variety of approaches such as continuous flow analysis (CFA) for the analysis of impurities, but also ion chromatography, ICP-MS and a number of other methods used for high resolution measurements of the impurity content in ice cores. Laser spectroscopy has replaced older-generation technology such as mass spectrometry for the analysis of some gases preserved in polar ice.

ICAT aims to educate a new generation of ice core researchers and foster a collaborative environment for future glaciological projects.

The course will enhance the knowledge between PhD’s within the ice core community on new methods developed for the analysis of ice core climate.

Application will open shortly and the application deadline is 1st of June.

PhD defense by Niccoló Maffezzoli-SODIUM, IODINE AND BROMINE IN POLAR ICE CORES. @ room 235, second floor
Oct 12 @ 13:00 – 17:00

PhD defense by Niccoló Maffezzoli

Title: SODIUM, IODINE AND BROMINE IN POLAR ICE CORES.

Abstract: This research focuses on sodium, bromine and iodine in polar ice cores, with the aim of reviewing and advancing their current understanding with additional measurements and records, and investigating the connections of these tracers with sea ice and their feasibility as sea ice indicators. Modern Arctic sea ice decline clearly yields further motivation in this direction, as the reconstruction of past sea ice conditions could provide clues to the mechanisms in play nowadays and in the future projections. Inductively Coupled  Plasma Mass Spectroscopy (ICP-MS) has been applied for the determination of Na, Br and I in firn records retrieved at Law Dome and Talos Dome (Antarctica) and in the NEEM and Renland ice cores (Greenland).
The dissertation is presented as a monograph. It is structured in a way that would logically bring the reader from the broad perspective of sea ice and ice cores into the details of the physical and chemical transformations of these impurities from their emission to their deposition and finally to their determination in ice cores and interpretation of their climatic significance. This view reflects, to some extent, the thread of understanding that led to the research activities.
Chapter 2 briefly introduces sea ice, with particular focus on its salinity as a source of sea salt aerosols. Some features regarding the role of sea ice in the climate system and the differences between sea ice in the two hemispheres are described. The chapter ends with a brief summary of the state-of-the-art of the chemical tracers that are used in ice cores and marine sediment cores to reconstruct past sea ice.
Chapter 3 introduces ice cores with a geochemical perspective. The historically measured ions and compounds are described, together with their climatic relevance. The chapter ends with a description of the main analytic al techniques used to measure ionic and elemental species in ice cores.
Chapter 4 introduces sodium, bromine and iodine with a theoretical perspective and a particular focus on their connections with sea ice. Some of the physical and chemical properties that are believed to affect the sea salt aerosol signature in ice cores are described. Halogen chemistry is presented, with a particular focus on the halogen sources and radical chemistry in the polar boundary layer. The chapter continues with a historical review of the relevant atmospheric studies that have demonstrated the activation of halogen compounds and the importance of halogen chemistry at high latitudes. Finally, the use of sodium and bromine as sea ice tracers is introduced.
Chapter 5 describes the Renland ice core, drilled in coastal East Greenland in 2015 as part of ”Ice2Ice”, a project which aims at understanding the causes of past abrupt climate changes in Greenland. The study of the timescale and other glaciological parameters led to the calculation of the annual accumulation rate for the past 4000 years. Finally, a study of the potential sea salt  aerosol sources arriving at the ice core site is presented, using back trajectory analyses of the past 17 years. The results identify the aerosol source area influencing the Renland ice cap, a result necessary for the interpretation of impurity records obtained from the ice core.
Chapter 6 reviews the published ice/snow measurements of bromine and iodine at polar latitudes. Where available they are compared to atmospheric halogen measurements. A selection of sodium records from the same locations is included to provide a more complete picture. The additional measurements performed during the research activities are also displayed. With the goal of presenting and extending the state-of-the-art of knowledge of bromine and iodine in polar snow, a critical comparison between the proxies is adopted, trying to elucidate the established and the unknown features and their potential as sea ice indicators. The last section is dedicated to the measurements of sodium and bromine in the Renland core, which could provide the first ice core-based reconstruction of Arctic sea ice in the Greenland Sea for the last 125 kyr.

EGRIP, NEGIS and ReCAP meetings 2017
Oct 29 @ 08:00 – Nov 3 @ 17:00

Dear all

The dates are now fixed for the NEGIS workshop and EGRIP Steering Committee meeting 2017. I have been asking around and this seems to be the best we can do.

I would like to ask the consortia chairs to plan when they want to have their meeting (and if they need one or two blocks for the meeting). The consortia list is here: consortia-meetings-2016

After the EGRIP fieldseason, beginning of September, I will email all chairs again to finalize the program.

egrip-group-picture-small

The NEGIS workshop is intended to be a workshop covering all activites on NEGIS – from iceridge to ocean. I would ask you to email me if you are interested in participating and also names (and emails) for researchers outside the EGRIP community we would like to invite.

the very best

Dorthe
