MarineBasis-Nuuk has been conducting year-round monthly hydrographic water column measurements at the standard monitoring station (GF3) since october 2005. Short-term (ca. 2 hours) free-drifting sediment trap array was deployed at 60m using double sediment traps (KC Denmark) consisted of parallel acrylic cylinders mounted in a gimbaled frame equipped with a vane. Prior to deployment, the traps were filled with filtered seawater with added brine to increase the salinity by ca. 5 psu.
