Autosub Long Range beneath Ronne Ice Shelf (2018): hydrographic, velocity and turbulence observations along the Modified Warm Deep Water Inflow
Autosub Long Range (ALR) was deployed along the Modified Warm Deep Water Inflow beneath Ronne Ice Shelf in February 2018 as part of the Ice shelves in a warming world: Filchner Ice Shelf system large grant, Antarctica. The vehicle was equipped with a Seabird Conductivity-Temperature-Depth (CTD) sensor, two Teledyne Acoustic Doppler Current Profilers (ADCPs), one upward looking and one downward looking, and a nose-mounted Rockland Scientific International MicroRider turbulence package. ALR followed a rhumb line course beneath the ice shelf, running approximately parallel to the 400 m isobath. The vehicle alternated between stretches of bottom tracking and top tracking in a square-wave pattern, while maintaining a minimum clearance of 80 m between the vehicle and the ice base or seabed.
Funding was provided by the UK Natural Environment Research Council Large Grant Ice shelves in a warming world: Filchner Ice Shelf system, Antarctica (Grant No. NE/L013770/1).

- Statement
- From the Seabird SBE-52 Conductivity, Temperature and Depth sensor, the temperature data has an accuracy of ±0.002 °C and the conductivity data has an accuracy of ±0.0003 S/m. Post-deployment, the SBE-52 was calibrated against ship-based CTD casts taken from RV Polarstern, with small corrections made to both temperature (+0.0024°C) and conductivity (+0.0002 S/m). The stated accuracy of the Teledyne RDI 300 kHz Workhorse ADCPs is 0.5% of the water velocity relative to the ADCP ± 0.5 cm/s. The stated accuracy of the shear probes in the Rockland Scientific International MicroRider turbulence package is 5%. Missing values are indicated with a value of -9999.
