In this deliverable, we present year-long observations collected by a turbulence instrument cluster (TIC) deployed within the ice-ocean boundary layer beneath the Fimbul Ice Shelf (January 2024 - January 2025).The deployment site, located beneath an ice shelf basal channel (70.37°S, 0.10°W), is an area where periodic warm-water intrusion events have previously been reported (Hattermann et al., 2012). This site provides a wide range of environmental conditions in which the relationship between oceanic turbulence and melt rate can be investigated. The TIC recorded water temperature and flow speed at 5 Hz for 15 minutes every two hours. Temperatures were calibrated against an RBR sensor deployed at the same site. These observations provide the basis for estimating the turbulent kinetic energy and turbulent heat flux at the ice-ocean boundary layer and their relationship to basal melting.
