Abstract:
To monitor particle fluxes and near bottom hydrographic variability a modified version of the benthic Bottom Boundary (BOBO) lander was deployed at 57° 29.09 N, 27° 54.53 W on the Gardar Drift at a water depth of 2630 m. These measurements cover the period from 16/09/2007 to 09/09/2008. Salinity and temperature were logged every 15 min at 3 metres above the seafloor with an SBE-16 CT sensor. Two Seapoint optical backscatter sensors were fitted to the lander at 1 and 3 metres above the seafloor recording data every 15 min. Biofouling of the sensor windows may have affected the results, and the lowest sensor (1 mab) appeared temporarily saturated by high turbidity. Full details about the deployment can be found in Jonkers et al., 2010 (doi:10.1016/j.dsr.2010.05.005).
