| Summary: | In this data file nutrient, DFe and raw CTD data are available used for the paper "Diapycnal mixing across the photic zone of the NE-Atlantic". Variable physical conditions such as vertical turbulent exchange, internal wave and mesoscale eddy action, affect the availability of light and nutrients for phytoplankton (unicellular algae) growth. It is hypothesized that changes in ocean temperature may affect ocean vertical density stratification, which may hamper vertical exchange. In order to quantify variations in physical conditions in the Northeast Atlantic Ocean, we sampled a latitudinal transect along 17 degrees 5minutes W between 30 and 63 degrees N in summer. A shipborne Conductivity-Temperature-Depth CTD-instrumented package was used with a custom-made modification of the pump-inlet to minimize detrimental effects of ship motions on its data. Thorpe-scale analysis was used to establish turbulence values for the upper 500 m from 3 to 6 profiles obtained in a short CTD-yoyo, 3 to 5 h after local sunrise. ... |
