Abstract:
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).
