| Abstract | Concurrent nearshore measurements of temperature, salinity, and chlorophyll fluorescence from three moorings offshore of Elands Bay, within St Helena Bay, Southern Benguela, in water depths of ~22 m (mooring 3), ~50 m (mooring 2) and ~62 m (mooring 1). The data were originally presented in "Lucas, A. J., Pitcher, G. C., Probyn, T. A., & Kudela, R. M. (2014, March). The influence of diurnal winds on phytoplankton dynamics in a coastal upwelling system off south -western Africa. Deep Sea Research Part II: Topical Studies in Oceanography,101,50–62. doi: 10.1016/j.dsr2.2013.01.016", and were further investigated in "Fearon, G., Herbette, S., Veitch, J., Cambon, G., Lucas, A. J., Lemarié, F., & Vichi, M. (2020). Enhanced vertical mixing in coastal upwelling systems driven by diurnal‐inertial resonance: Numerical experiments. Journal of Geophysical Research: Oceans, 125, e2020JC016208. https://doi.org/10.1029/2020JC016208". |
| Methods | The origin and processing of these data is described in detail in the methods section of Lucas, A. J., Pitcher, G. C., Probyn, T. A., & Kudela, R. M. (2014, March). The influence of diurnal winds on phytoplankton dynamics in a coastal upwelling system off south -western Africa. Deep Sea Research Part II: Topical Studies in Oceanography,101,50–62. doi: 10.1016/j.dsr2.2013.01.016.The Wirewalker wave powered profilers were equipped with 16 Hz profiling Seabird (SBE) 49 Conductivity, Temperature and Depth (CTD) sensors and Turner designs Cyclops 7 Chlorophyll a fluorometers. The data provided by the originator has been migrated into CF-1.7 compliant NetCDF files for each mooring position. Mooring 1 is located at 32.29113333 S and 18.2168 E, mooring 2 is located at 32.29138333 S and 18.26615 E, and mooring 3 is located at -32.291 S and 18.3107 E. Time is measured as seconds since 1970-01-01 00:00:00 00:00 UTC+2. |
