SITES Water discharge and water chemistry at Röbäcksdalen – northern agricultural catchment

21 February 2024

The ongoing work on estimating the discharge in the streams at Röbäcksdalens field station was initiated in the spring of 2023. At the time, the final phase of the snowmelt runoff was generating a peak stream flow. At Röbäcksdalen, a tracer is used to measure the discharge. The tracer is common table salt and it is injected (the mass balance method) into the stream, generating a dispersed cloud of conductivity change in the stream. The change in conductivity is then used to estimate the discharge.

Joint SITES Water and AquaNet workshop at Erken

15 February 2024

This week SITES Water and SITES AquaNet field and lab techs met at Erken Laboratory for a joint workshop across the two Thematic Programs. The workshop focused on the current status and development of SITES Water and SITES AquaNet, along with sessions specific for the technical staff at the station. The sessions addressed life as field and lab tech, field and lab protocols, sensor calibrations, greenhouse sampling and hydrological measurements. The group also took a walk on ice-covered lake Erken for a hands on snow and ice measurement demonstration by the Erken staff.

SITES leadership meeting at Grimsö Wildlife Research Station

01 February 2024

To kick-off the year, SITES leadership team, including the Secretariat, the SITES Station Managers and Thematic Program leads, met in-person at SITES Grimsö Wildlife Research Station this week (30-31 Jan 2024). The meeting provided an opportunity to reflect on SITES accomplishments from 2023 as well as strategize and prioritize for 2024.

Several SITES Water datasets from Asa uploaded on the SITES Data Portal

19 January 2024

The ongoing process with uploading data to the SITES Data Portal continues. For Asa Research Station, as ice beings to settle on lake Feresjön, the SITES Water monitoring is reduced from biweekly sampling to monthly. This allows for more time to process and upload SITES Water data.

January Collaboration in Focus: SITES Spectral allows links to remotely sensed satellite data

09 January 2024

The SITES 2024 Calendar theme is “SITES Collaborations”. SITES aims to promote excellent ecosystem research and high-quality data that support this research. This includes collaborations that increase the number of projects that utilize multiple SITES stations and connect between aquatic and terrestrial processes. Further, SITES aims to strengthen the collaborations with relevant research infrastructures and networks across Sweden and internationally, including data infrastructures and services.

The final data retreat of the year, brings together Svartberget and Röbäcksdalen

08 December 2023

The last SITES data retreat of the year is taking place in Umeå this week with Svartberget Research Station. Updates to include the 2023 data to the stream level and discharge at the five locations existing on the SITES Data Portal (Catchment locations, C2, C4, C5, C6 and C7) have already been made. Stream level and discharge data from additional locations will be added to the SITES Data Portal soon! The lake water level data from Stortjärn has also been updated for 2023 and other data updates from the lake are in the works. 

December Data in Focus: Ten years of stream discharge from Asa’s Feresjön inlet stream

01 December 2023

The SITES 2023 Calendar theme is “Data in Focus”. The openly available data produced within SITES and stored on the SITES Data Portal is the “golden thread” of the infrastructure, allowing users access to ecosystem data that covers diverse habitats and climate zones across geographical gradients in Sweden. Each month follow along as we highlight a unique SITES dataset.  

Data Retreats Continue, on to Bolmen

30 November 2023

This week the data retreats continue: next in line is Bolmen, SITES associated research station in Småland. The team is working on establishing workflows and a data structure for the first SITES Water related data sets coming from Lake Bolmen and to discuss future multi-station collaborations. The station lead around Sydvatten have ambitious plans to develop a high-frequency measurement program on the lake in the coming years, which is planned to follow the SITES Water layer structure.
