Fieldwork was conducted in July 2022 in the coastal waters around Herschel Island - Qikiqtaruk, Canada. Seven sampling days were carried out in two consecutive weeks. Two transects were sampled repeatedly: one transect was directly affected by the discharge of a retrogressive thaw slump, while the other transect was located in front of a permafrost cliff coast. For both transects, the targeted sampling stations had the following distances from the shore: 10 m, 50 m, 100 m, 500 m, and 1000 m. These targeted stations could not always be sampled precisely due to the weather conditions, which explains the deviations in the coordinates. Salinity, electrical conductivity, water temperature, and water depth were determined with a CTD CastAway. At least two water samples were taken per sampling station per day. For stations with water depth > 5 m, an additional sample was taken at the depth of the thermocline (based on previous CTD measurements). Seawater was sampled using a UWITEC water sampler (USB ...
