Processed seawater temperature, conductivity and salinity obtained at different depths by CTD buoy 2019O5 as part of the MOSAiC Distributed Network

CTD buoy 2019O5 was deployed in the MOSAiC Distributed Network in the Northern Laptev Sea in early October 2019 as part of a set of eight identical ice-tethered buoy systems, each consisting of 5 Seabird SBE37IMP Microcat CTDs mounted along an inductive modem tether at depths of 10, 20, 50, 75 and 100m. The surface unit of the buoy prompted the instruments for a measurement every 10 minutes, which was then transmitted to a base station via iridium along with GPS position and time, as well as surface temperature. 2019O5 stopped transmitting data in the northern part of Fram Strait in mid-July 2020, after 278 days of drift through the Central Arctic Ocean, The buoy data were quality controlled by means of outlier detection using global limits, moving average filters and manual inspection. The dataset was carefully checked for inconsistencies, especially in the salinity. Where appropriate, parameters were modified to enhance the quality. A (slightly modified) quality flagging scheme was applied according to the Ocean Data Standards Volume 3 (UNESCO 2013), where 1 = Good, 2 = Good (Modified), 3 = Questionable, 4 = Bad, 9 = no data. Finally, the data were validated against independent measurements. Details are available in the data paper indicted below.
