Turbulence beneath Larsen C Ice Shelf, Antarctica (2012)
Turbulent velocity fluctuations in the ice shelf-ocean boundary layer beneath Larsen C Ice Shelf were observed using two turbulence instrument clusters (TICs) deployed 2.5 m and 13.5 m beneath the ice shelf base in December 2011. Each TIC sampled the velocity fluctuations at a rate of 5 Hz, and were...
