Here we present an extensive dataset of turbulence from an Ocean Microstructure Glider (OMG) campaign in an energeticly-forced coastal system, Te Moana-o-Raukawa (Cook Strait), the water channel separating the North and South islands of Aotearoa (New Zealand). The microstucture data is combined with glider-based background stratification to study both the mechanisms driving energetic turbulence and its fundamental capacity to mix stratification.
This study used a Teledyne Webb Research Slocum G2 glider equipped with a Seabird CTD sensor and a Rockland Scientific MicroRider 1000-EM microstructure package. Temperature, conductivity, and pressure data were sampled at 0.5 Hz, and subsequently processed to remove spikes. The accuracy within calibration range of temperature and conductivity were +/-0.002oC and +/-0.0003 S m-1, respectively. Glider data processing was completed using the SOCIB glider toolbox (https://github.com/socib/glider_toolbox; Troupin et al. (2015)). Glider data processing includes salinity lag correction for the thermal lag error for the un-pumped CTD unit. Data were averaged in vertical bins of 1 m. Microstructure measurements of shear and temperature are gathered at 512 Hz, and direct current speeds are recorded by the electromagnetic (EM) current meter mounted adjacently to the microstructure probes.
