Abstract:
The CTD measurements were collected in Isfjorden (78°70’ N-78°27’ N, 13°-17° E), Spitsbergen during the cruises on the R/V Oceania conducted by the Institute of Oceanology of the Polish Academy of Sciences (IO PAN) in the late July – early August surveys (covering the main melting season) in 2013–2019 (24-25 July 2013, 24 July 2014, 10 August 2015, 9-10 August 2016, 12-13 August 2017, 2-3 August 2018, 26-27 July 2019). The continuous, high resolution laser-based measurements were performed within the upper 70-m water column along a 60-km transect crossing Isfjorden, starting from sampling station located at the mouth of the southern branch of Isfjorden – Adventfjorden (ISA), through station in the central part of Isfjorden (ISF3 sampling station) up to the innermost part of Billefjorden (BAB sampling station). A conductivity-temperature-depth sensors (CTD, SBE 911plus, Seabird Electronics Inc., USA) and a fluorometer (Seapoint Sensors Inc., USA) were used to collect presented data.
