Tutkijat tiivistävät yhteistyötä – kansalaishavainnot Saharan hiekkapölystä sekä lumesta ja jäästä kerätään yhteen tietokantaan

Apr 12, 2022adminSnowArctic Centre, Lumi, SYKE, University of Lapland

Nyt Lapin yliopiston Arktinen keskus, Ilmatieteen laitos ja Suomen ympäristökeskus (SYKE) tiivistävät yhteistyötään lumeen liittyvien kansalaishavaintojen keräämisessä. Havaintoja voidaan hyödyntää entistä paremmin, kun tiedot tallentuvat yhteen tietokantaan. Kansalaishavainnot täydentävät tutkijoiden seuranta-aineistoja ja antavat havaitsijalle itselleen mahdollisuuden seurata oman alueensa tilannetta ja pitkän ajan kehitystä. Paikalliset elinkeinonharjoittajat ja elinkeinojen hallintoväki voivat myös käyttää näitä havaintoja. Kokemuksia uudesta verkkopalvelusta olisi hyvä

Springing into CHARTER fieldwork & new publication

Apr 5, 2022adminProject NewsFieldwork, Hans Tømmervik, Leena Leppänen, Otto Habeck, Rain on Snow, Sirpa Rasmus, Timo Kumpula

Longer daylight hours and milder temperatures means optimal snow covered fieldwork time. A number of CHARTER project reseachers are undertaking fieldwork periods this week. Temperatures are mild at this time of year in northern Scandinavia, currently in the -8 to +2 degrees range during the day and -15 to -8 overnight. The melting and refreezing

In good CHARTER news, we are delighted to welcome Simo Sarkki to the project team. Simo has a PhD in anthropology and holds docentship on “anthropology of environmental governance” at the University of Oulu, Finland. Sarkki’s research interests include science-policy interfaces, land use in northern areas, scenarios, participatory approaches, and multi-level governance under the broader theme

Some fieldwork in Russia is underway

Conducting fieldwork in the midst of a pandemic has been a challenge for all academic projects that rely on fieldwork to be carried out ‘in the field’ to test hypotheses and gather raw data. Multiple fieldtrip have been cancelled, scaled back, or carried out in much-reduced circumstances. This has certainly been the case for the

Bringing Citizen Science & Snow to the Classroom

Under gorgeous spring skies by the banks of the Ounasjoki river last Friday, CHARTER Arctic researchers Sirpa Rasmus and Leena Leppänen brought their snow science to the next generation of researchers. With the participation of the Grade 5 students from the Rovaniemi Steiner school students and their teacher, the principles of snow structure, snow pack,

Tutkijat toivovat kansalaisilta lumihavaintoja

Lumen päälle satava vesi ja lumipeitteen jääkerrokset ovat CHARTER- hankkeessa erityisen kiinnostuksen kohteena. Jäiset kerrokset vaikuttavat kasvien talvehtimisoloihin ja vaikeuttavat eläinten kaivautumista lumen läpi. Tällä on merkitystä myös pohjoisen elinkeinoille, muun muassa poronhoidolle. Lumipeitteen kerrosrakenne ja jääkerrokset havaitaan paikan päällä tehtävien lumikuoppien avulla. Näitä havaintoja hyödyntävät satelliittiavusteisten lumihavaintojen kehittäjät sekä lumi- ja ilmastomallinnuksen tekijät. Havaintoaineistoa

CHARTER welcomes snow observations by everyone!

One aspect of the CHARTER project is to gain a better understanding of snow icing events, such as happens when rain falls on snow. This affects animal movements and behaviours and hinders animals from digging through the snow. Icing also impacts plants, and are very relevant for livelihoods such as reindeer herding. Snow profile observations

Important new publication on Rain on Snow phenomena with CHARTER input

Dec 2, 2021adminProject News, Published articlesBruce Forbes, Julienne Stroeve, Rain on Snow

An important new article with substantial CHARTER input has just been published in the journal Nature Communications. The article is titled New climate models reveal faster and larger increases in Arctic precipitation than previously projected. In other words, climate models are predicting that snowfall will be replaced by rain fall in the future, and this will occur at a faster rate than previous models suggested. You can download the article here (open access)

This phenomena is referred to as ‘Rain on Snow’ or ROS and it is something that is predicted to happen more often with potentially disastrous impacts on biodiversity in the Arctic. By way of example, tens of thousands of reindeer have died as a result of repeated ROS events in the Yamal peninsula and Finland in recent years, with potentially catastrophic consequences for reindeer herding peoples and cultures. The phenomona is also hazardous for other wildlife as rain refreezes and turns to ice, creating a physical barrier to pastures and nutrition. While ROS events are not unheard of, the frequency with which they are happening is.

The question of how to reach people and tell them about your research project, especially at the results stage is a difficult one. People are generally overwhelmed with information from multiple angles, and let’s be frank, emails seem very 2000. Do people even read them anymore? We jest, of course! But marketing research (eek!) suggests
