Salinity and Temperature data from the Angmagssalik Array in the Denmark Strait Overflow - 1998 to 2015
Summary
Salinity and temperature data recorded near bottom (20m height from seabed) between 1998 and 2015 by Seabird-Electronics-37 SM MicroCAT instruments. The data were calibrated and aggregated from those published with the following publications: Opher (2021) and Opher et al (accepted). This is a subset of data collected the Angmagssalik Denmark Strait Overflow Array that was in place between 1986 and 2015.

Lineage
These data were collected at across 5 mooring sites along a section (from approximately 63.63 N 36.80 W, to 63.37 N 36.08 W) between 1998 and 2015. This is part of the Angmagssalik Denmark Strait Overflow Array which was in place between 1986 and 2015 as a collaboration between Cefas, IfM-Hamburg and the Finnish Institute of Marine Research over for a series of projects. This initiative was predominantly coordinated by EU projects (ASOF, THOR), but funded by multiple sources. The instrument used was the Seabird-Electronics-37 SM MicroCAT. The salinity data are derived from conductivity, temperature and pressure measurements from the microCAT instruments, which have an initial accuracy of 0.0003 S m-1, 0.002°C and 0.1% of full-scale pressure range respectively, but which are prone to fouling, sediment build up or electrode damage to the conductivity cell. Therefore, the microCAT data were systematically calibrated using ship-deployed conductivity-temperature-depth (CTD) casts as a reference. The microCAT conductivity measurements frequently underestimated the true conductivity, relative to the CTD reference. Full calibration details in Opher (2021). The data is available as 4 data sets that are collated from 5 mooring sites by combining 2 of the full array sites. The data labelled as F in the dataset are an aggregation of moorings F1F2 and F1 (Opher, 2021) with a geographic distance between separate mooring deployments of up to 9 km - note this location caveat in reuse. The distance between separate mooring deployments for UK1, UK2 and G are less than 1 km. The typical location of the mooring instruments are shown in ang_mooring_deployment.png.
