Only a few lakes remain to be investigated, with the most recent sediment sampling taking place at Lake Erken. Sediments along the four transects with GHG chambers were successfully collected in mid-September. At each GHG transect two sediment cores were collected, representing a shallow and deep depth within the transect. Most sediment was sampled with a gravity corer, however at shallow depths within the reed belts innovative sampling techniques were required.
The next lake scheduled to be sampled as part of the SITES Water sediment campaign is Almbergasjön (Abisko Scientific Research Station), where a deep sediment core has already been collected, and short sediment cores will be collected next month.
