Can we use the general interest of Arctic climate to introduce students to climate science? In the project IGLO we aim make knowledge about the Arctic climate system more accessible for high school students in Scandinavia. We have done that by developing IGLO, a web portal that helps teachers build their own teaching on Arctic climate change (see more at www. iglo.w.uib.no). IGLO is thus a web portal that works as a tool that makes it easier to plan your own teaching. The purpose is to make it easy and efficient to find high quality material about Arctic climate change. The web portal is especially made to target the teachers. Here updated information about climate changes (and updated animations and graphs) is presented. Furthermore, the web portal is designed for teachers by categorizing all types of teaching material (e.g. "classical" climate change animations) into subjects and themes so that teachers easier can handpick and «build their own teaching». In addition, we give students and other interested people opportunities to follow the life of young scientists by using an Instagram account where young Arctic climate researchers communicate their work. The goal is that project IGLO helps to bridge the gap between Arctic climate researchers and teachers. [ABSTRACT FROM AUTHOR]

In ice cores continuous flow analysis (CFA) are often used to measure impurities, such as insoluble dust, conductivity and ions by means of fluorescence or absorption techniques after transport from the field to the laboratory. In such a system the ice core is melted on a melt head that separates the potential contaminated outer section from the untouched inner section. The inner melt water stream is then used for high resolution measurements of chemical impurities. However for fragile firn and snow core the transport from the field to the laboratory compromises the integrity of the samples. Here we present a novel developed Light In-Situ Analysis (LISA) - Portable Continuous Flow Analysis (CFA) box for determining chemical impurities in snow and firn directly, while still in the field. A preliminary version of the box has been tested successfully on 2 meter snow cores at the EastGRIP ice core drilling site in 2017 in Northeast Greenland at -22°C. This proof-of-concept device demonstrates that successful measurements can be conducted under open-field conditions to constrain conductivity and thus annual accumulation, but only one parameter (conductivity) was continuously measured. The box have been further optimized to include also opportunities for two sets of fluorescence measurements such as eg. peroxide, calcium or ammonium. In low accumulation sites in Greenland such proxies can be used to identify annual layers in the snow pack. In addition the density of the snow cores can be determined by monitoring the melt speed in combination with the energy used on melting. The two sets of measurements combined can provide the annual accumulation. [ABSTRACT FROM AUTHOR]
