The first AQUACOSM-plus transnational access (TA) experiment using the SITES AquaNet infrastructure finished in Mid-August. The experiment investigated functional and compositional consequences of run-off variability and was synchronized at Lake Erken and Bolmen during 6 weeks this summer. It brought together a team that involved 10 TA participants from Spain, Turkey, Ireland, Hungary and the Czech Republic, 5 participants from AQUACOSM-plus partners at IBG and Oldenburg University in Germany, and several local participants from Uppsala and Lund University.

The summer season at Tarfala Research Station (TRS) has been very wet. Heavy rainfall during a couple of days at the end of August brought along temporary and also more permanent changes: Between Lake Tarfala and TRS, Tarfalajokk became so wide and carried so much water that any idea of crossing needed to be dismissed. Lillsjön (translating to “the little lake”) just south of TRS turned into a rather large lake.

After more than two years of travel restrictions and limited field research activity due to the Covid-19 pandemic, Abisko Scientific Research Station is finally back to full speed. The summer of 2022 has been one of the busiest summers in the history of the research station, with the station constantly at – or beyond – full capacity, June through September.

The Global Soil Biodiversity Observation Network (Soil BON) is working in partnership with the Global Soil Biodiversity Initiative (GSBI) and other global and regional partners to increase the monitoring of soil ecosystems.

The pandemic has slowed down and Röbäcksdalen is able to welcome visitors once again.

Friday was the second big sampling day for the SITES AquaNet and Aquacosm mesocosm experiment. The experiment is examining the impact of changes in run-off on lake plankton communities since rainfall patterns, and thereby run-off, are expected to be impacted by climate change.

Surprisingly the extreme snowfall events in early April have not delayed the start of the summer season in the Tarfala valley. A warm May and June caused rapid snow melt and the summer conditions are now quite normal. The discharge in the rivers has been generally high over the last month but has now settled to a normal rate. The ice covering the lake Tarfalasjön is still solid but is expected to break up soon. The Tarfala Research Station opened on June 28th and the SITES sampling program is just now getting started for the year.

The wild boar (Sus scrofa) project at Grimsö Wildlife Research Station explores several research topics, including, the effects of supplemental feeding on local boar populations and the surrounding habitat. Supplementary feeding is a management practice where attractive food and nutrients are supplied on daily basis at feeding stations. These feeders are often used in hunting to attract animals to a set location but are also used with the goal of shifting habitat use away from agricultural fields.

PhenoCams are cameras designed specifically for tracking the timing of when plants grow buds, leaf out, flower, fruit and die back, the science known as plant phenology. In Abisko, SITES is operating a PhenoCam which is programmed to take pictures towards Mount Nuolja several times per day. The concept of repeat photography has been increasingly used to continuously monitor the foliage and canopy changes mainly because of its low cost, high temporal resolution, high-quality imagery, and automatic operation.

Abisko Scientific Research Station was built in 1912 after the research station in Katterjokk burned down. The following year, the meteorological measurements were started, and for several decades data has been collected on behalf of SMHI. The over one-hundred-year long series of measurements has qualified the measuring station as a Centennial Observing Station, an award given by the World Meteorological Organization WMO.
