Haakon Mosby, 26 May-15 June 2016, 51 profiles - Cruise KB2017606, R.V. Kristine Bonnevie, 10-24 March 2017, 32 profiles - Cruise HB2017618, R.V. Kristine Bonnevie, 2-15 September 2017, 9 profiles PROVOLO (Watermass transformation processes and vortex dynamics in the Lofoten Basin of the Norwegian Sea) is led by the Geophysical Institute, University of Bergen (PI: Ilker Fer) and is funded by the Research Council of Norway (project number 250784) for the period 01.01.2016-31.12.2019. PROVOLO studies the processes and pathways of energy transfer and mixing in the Lofoten Basin and their role in water mass transformation. The data set includes 2-decibar vertically averaged profiles of dissipation rate of turbulent kinetic energy, in situ temperature (ITS-90 scale) and salinity (practical salinity scale). Profiles are collected using Rockland Scientific vertical microstructure profilers (VMP), VMP5500, VMP6000 and VMP2000. The VMP2000 (2000 m rated, used in all three cruises) is loosely tethered and is deployed using a winch and a line-puller system. VMP5500 (only in June 2016) and VMP6000 (in June 2016 and March 2017) are deep free-fall profilers. Dissipation rate is measured using two airfoil shear probes. Profiles are averages from the two shear probes. The temperature and salinity profiles are measured from the SBE sensors on the same instrument. VMP2000 has a pumped CTD system whereas deep profiles have an unpumped CTD. Careful corrections for temperature/conductivity sensor time lag and thermal lag were made, however, the salinity profiles especially from the deep profilers must be used with caution. Only downcasts from VMP2000 and only upcasts from the deep profilers are processed using the Rockland Scientific Matlab routines. Resulting profiles are quality controlled, but still require caution from the user. More details are provided in the attached cruise reports.' comment = 'Ocean microstructure profiles from three PROVOLO cruises to the Lofoten Basin of the Norwegian Sea: - Cruise HM2016611, R.V.
