York and Swansee Universities has recently received funding for a SkyGas-system at Följesjön in Skogaryd. The SkyGas system moves in a 3D pattern, similar as a camera attached to the roof at a sports arena. A Gas-Flux chamber will be moved around at different locations at Följesjön along with a micro metrological setup.
This setup will combine resources and knowledges from SITES Water and Spectral SITES. A mire at Skogaryd is equipted with a similar SkyLine system. Further research approaches from this infrastructure will be to model footprint theories within ICOS and measure green-house gases with lasers. The SkyGas-sysmen is also an interesting feature in cropping systems.
Researchers at Umeå University has received a grant from Knut and Alice Wallenberg foundation. The project is entitled; Climate change induced regime shifts in northern lake ecosystems. Several of the study sites are located at or in the vicinity of SITES Abisko and Svartberget field research stations.
Jan Karlsson and his fellow applicants were granted with 37 million SEK over the next five years. One of the outcomes of the project will be to develop ecosystem models to be used to predict future production of fish biomass and greenhouse gas in northern lakes.
SITES will present the project in more detail during 2017.

Four of the SITES stations involved in SITES AquaNet mounts their floats during this autumn. Erken was first and initiated during late September, all the participants attending the SITES AquaNet workshop there got to see the progress and possibilities. This week personnel from Svartberget has put together their float-device into the larger platform in lake Stortjärn. Asa and Skogaryd are next in line.
The float platforms are the fundament of the SITES AquaNet infrastructure, it will hold the structure of the mesocosm bags, act as base for loggers mounted and used in the manipulations and at the same time provide a safe work environment. During summer 2017 a test experiment will run at all four platforms, and then the structure act as a resource for research questions related to manipulation of small aquatic ecosystems.

SITES spectral is one of the three common initiatives within SITES. Their overall aim is to support world class field research with infrastructures. SITES Spectral is holistic and common across eight of SITES stations where each stations has similar type of instrument and measurement setup. The program collects spectral information from sensors and phenological cameras in mast/towers and Drones (UAW). Sensors are mounted in towers and masts capturing incoming and reflecting radiation. Phenological cameras capture vegetation development and the UAW which are used to scale the program to larger areas. Information from sensors and UAV are inter-calibrated from the smaller fixed points to the larger area captured by the UAW. One extension of this program is the possibility to calibrate satellite data from remote sensing.
The decision to change the name was made at a workshop October 14, partly to emphasize the differences between SITES Spectral and the network of Nordpsec. Apart from discussions, information and updates on technical challenges, calibrations and decisions regarding equipment, an inspiration-talk was given by Kjell Blomgren form the phenological network in Sweden on how researchers like him, can use data from SITES Spectral.

SITES partners, University of Gothenburg, Stockholm University, Uppsala University, the Swedish Polar Research Secretariat and SLU gathered for a meeting regarding the upcoming application for SITES continuation. The meeting discussed, among other things, SITES interpretation of the conditions for the next phase and a plan for further contact during the development of the application. The partners also gave specific comments on challenges and opportunities of an extension.
Jakob Kuttenkeuler and colleagues from Royal institute of Technology, KTH, visited Tarfala where they used a Maribot A.N.K.A developed for autonomous hydrographic mapping in shallow waters to produce a bathymetry map of the Tarfala Lake. The map will provide background information for the SITES water project.
They also aided the deployment of temperature sensors array that will stay in the lake during winter.

The thirteenth Krycklan symposium attracted over 80 people to participate in two sessions on forest ditches and on the management of small streams. The program presented invited speakers from Finland and Canada. Hjalmar Laudon, professor in forest biogeochemistry and leader of the research Krycklan is pleased with this year's symposium.
- Krycklan is about research infrastructure, but also about people. The symposium is a way to welcome researchers from all around the world to come and work with us, but there is one important condition – we work with open data, says Hjalmar Laudon, who also works as a research leader in Future Forests.
Over the years, the Krycklan symposium has become a well-established meeting place for scientists from different parts of Sweden and the world. Participants also represent practitioners from authorities such as the Swedish Forests Agency and from the private sector and forest owners. Many participants return year after year, and seem to appreciate the open and welcoming atmosphere.

Small but important
This year's theme was forest ditches, small streams and forest buffer zones. All are components of aquatic ecosystems that are easily overlooked. Really small streams that you can easily step over without effort, and that might not even visible during parts of the year might at a first glance be perceived as less important parts of the watershed. . But it has been shown that 85% of the overall length of the watercourses consists of small streams whose catchments are less than one square kilometer.
- The small watercourses are capillaries of the forest waters, it is those who have contact with the forest soil. It is important that we begin to see the headwaters are not only important downstream, but we must begin to see them as important in themselves, because their buffer zones really control the water quality, says Hjalmar Laudon.

Are trenches streams?
Forest trenches divide forest stakeholders. On one side, we find those who want to restore the trenches in order to increase forest growth, on the other side those who see the forest trenches as problematic, from a nature conservation point of view.
- The idea was to open our minds to new approaches and issues by inviting experts in both small streams and forest ditches and try to combine different perspectives. The link between the artificial water bodies and the natural - how does it look? What do they have in common and what is unique?, says Hjalmar Laudon. And when should a ditch be treated as a stream? That is the key question in this discussion.

Facts:
Among this year's invited guests were David Kreutzweiser, Canadian Forest Service, John Richardson, University of British Columbia, Samuli Launiainen and Ari Lauren from the Finnish Natural Resources Institute LUKE, Timo Hiltunen from Metsähallitus, which manages state forests in Finland, and Axel Anderson, University of Alberta and Chris Evans, the Centre for Ecology & Hydrology.
Krycklan Catchment Study was initiated 35 years ago by Kevin Bishop and Harald Grip. Since then there have been over almost exponential increase in activities. Today, there are datasets from the study, which is unique in its scope and which attracts scientists from around the world to cooperate with SLU's successful forest water scientists.
Future Forests is a multi disciplinary forest research program driven by the Swedish University of Agricultural Sciences, Umeå University and the Forestry Research Institute of Sweden.
On the 6-9th of September, Linda-Maria Mårtensson, Deputy Station Manager at SITES Lönnstorp, attended the European Society for Agronomy conference in Edinburgh in order to promote the newly established SITES Agroecological Field Experiment at Lönnstorp. The presentation attracted a vivid interest, in fact so much that more hand-outs had to be printed!
