WORKSHOP: TEXTURE TOPICS IN TROMSØ(GEO-8134 Texture Analysis and Orientation Imaging)
When?Monday - FridayOctober, 15 - 19, 2012
AIMThe aim of the workshop is to familiarize participants with different methods of texture analysis and to discuss texture interpretations. This year the special emphasis is on the texture development in ice. The workshop presents an introduction to computer-integrated polarization microscopy (CIP), a method for the derivation of caxis polefigures, orientation, misorientation and orientation gradient images of uniaxial minerals such as quartz and ice. Other methods of texture analysis, EBSD and mtex, are presented in lectures and open discussions.Topics are: local (partial) and global (bulk) textures, type and strength of pole figures, interpretation of misorientations, texture-based segmentation, grain size and grain shape analysis. Practical application and analyses of natural and experimental samples will be demonstrated.

A World Glacier Inventory (WGI) is available through the National Oceanic and Atmospheric Administration (NOAA) at the National Snow and Ice Data Center (NSIDC). The dataset can be accessed at: http://nsidc.org/data/docs/noaa/g01130_glacier_inventory/.
Since 1999, NOAA at NSIDC has worked with the World Glacier Monitoring Service (WGMS) to make its WGI available online. While the WGI cannot claim to have all of the world's glaciers, it now has records for over 130,000. The NOAA at NSIDC team worked with an intern from the WGMS to check and update the documentation of existing records, and add over 25,000 new ones.
The WGI is a reference resource for the world's glaciologists and one of NSIDC's most popular datasets. The 50 fields included with each record contain parameters such as orientation, ablation area, and accumulation area, which glaciologists use to assess the condition of the glacier at the time of the inventory record, and to compare with later assessments. The WGI is an essential part of the Global Terrestrial Network for Glaciers (GTN-G), in turn part of the Global Climate Observing System (GCOS) underthe auspices of World Meteorological Organization (WMO).

Introduction to user requirement survey
In order to develop the Essential Climate Variables (ECVs) for sea ice, it is necessary to perform a user requirement survey and analyse the requirements to be extracted from the survey. The main sea ice variables contributing to the ECVs are ice concentration (SIC) and ice thickness (SIT), both of which have been observed from space for several years.
The requirement analysis will address coverage, resolution, bias, precision and stability of the SIC and SIT measurements, as well as product formats, grid and projection. Also requirements for other sea ice variables relevant for climate research will be addressed.
The requirements will be defined for a number of applications in particular climate modelling including model development, model validation, model initialisation, data assimilation, and other climate research activities such as time series analysis. The requirements will be analyzed in terms of how important they are for the different applications. The requirements are divided in two categories: minimum requirement ("MUST HAVE"), and target requirements ("NICE TO HAVE").
One specific issue is to assess the requirements for error estimation of the data sets to be provided in the project. Three parameters are defined (see figure below):
(1) Bias: offset of the mean satellite observations from the “true” values,
(2) Precision: scatter of multiple measurements of a constant target, and
(3) Stability: drift in observed mean value of a constant target over a decade.

A very unique event is taking place in Berlin April 24-30, 2012: The Greenland Eyes International Film Festival.
Greenland Eyes International Film Festival, taking place at renowned Arsenal Cinema April 24-30, 2012, offers a unique experience of one of the most fascinating places on earth. The festival is exceptional in its combination of multiple perspectives on today’s Greenland such as film, art, music, storytelling, politics and scholarship.
Greenland Eyes is proud to provide the Berlin audience with the first chance to get a comprehensive insight into films from and about Greenland. Starting with some examples from German-Greenlandic film history likeEskimo Baby (1917), starring Asta Nielsen, and SOS Iceberg (1932), starring Leni Riefenstahl, the festival focuses on the emerging Greenlandic film production and on international films showing today’s Greenland beyond widespread representations of a deserted ice-covered island, ‘eskimo exotism’ or sublime nature. Instead, the festival’s program will zoom in on urban Greenland; negotiations of the postcolonial situation; and reception of globalized pop culture in Greenland. Among others, the festival will screen (only for the second time in Germany) the first international Greenlandic feature film Nuummioq (2009), the international or German premieres of the first Greenlandic feature filmTikeq, Qiterleq, Mikileraq, Eqeqqoq, a low budget production from 2008; the most popular film in Greenland ever, Qaqqat Alanngui (2010); and the award winning short film ECHOES (2010) about the remains of the cold war in East Greenland.
The film program will be supplemented with the workshopGreenland Film in Context at Humboldt University’s Nordeuropa-Institut, focusing on theoretical and practical aspects of filmmaking in and about Greenland. We will be welcoming numerous guests, noteably from Greenland and Denmark, to share their expertise on traditional and recent representations of Greenland; current political and cultural debates; and the contemporary scene for visual arts in Greenland. Greenlandic singer-songwriter Nive Nielsen and actor and storyteller Makka Kleist will contribute additional features to an understanding of today’s Greenland. We are proud to announce our cooperation with .HBC, a beautiful music and culture venue at the center of Berlin, which will host the finissage party.
Welcome! Willkommen! Tikilluaritsi!

Researchers have updated HadCRUT - one of the main global temperate records, which dates back to 1850.
One of the main changes is the inclusion of more data from the Arctic region, which has experienced one of the greatest levels of warming.
The amendments do not change the long-term trend, but the data now lists 2010, rather than 1998, as the warmest year on record.

Three penguin species that share the Western Antarctic Peninsula for breeding grounds have been affected in different ways by the higher temperatures brought on by global warming, according to Stony Brook University Ecology and Evolution Assistant Professor Heather Lynch and colleagues. The work by Lynch and her team is contained in three papers that have been published online in Polar Biology,Ecology and Marine Ecology Progress Series (MEPS).
Lynch and her colleagues used a combination of field work and, increasingly, satellite imagery to track colonies of three penguin species -- Adélie, chinstrap and gentoo. The Adélie and chinstrap migrate to the peninsula to breed, while the gentoo are year-round residents.

The Greenland ice sheet is likely to be more vulnerable to global warming than previously thought. The temperature threshold for melting the ice sheet completely is in the range of 0.8 to 3.2 degrees Celsius of global warming, with a best estimate of 1.6 degrees above pre-industrial levels, shows a new study by scientists from the Potsdam Institute for Climate Impact Research (PIK) and the Universidad Complutense de Madrid. Today, already 0.8 degrees of global warming has been observed. Substantial melting of land ice could contribute to long-term sea-level rise of several meters and therefore it potentially affects the lives of many millions of people.
The time it takes before most of the ice in Greenland is lost strongly depends on the level of warming. "The more we exceed the threshold, the faster it melts," says Alexander Robinson, lead-author of the study now published in Nature Climate Change. In a business-as-usual scenario of greenhouse-gas emissions, in the long run humanity might be aiming at 8 degrees Celsius of global warming. This would result in one fifth of the ice sheet melting within 500 years and a complete loss in 2000 years, according to the study. "This is not what one would call a rapid collapse," says Robinson. "However, compared to what has happened in our planet's history, it is fast. And we might already be approaching the critical threshold."
Canadians have donated about $10,000 to help keep a unique High Arctic research station from closing after its federal funding stops, says the Canadian Foundation for Climate and Atmospheric Sciences.
