Scientific focus in summer 2024: In addition to continuing long-term objectives of IceBird, a scientific focus of the IceBird Summer campaing in 2024 is to validate and improve novel satellite-based sea ice freeboard and thickness estimates from altimetry missions like CryoSat-2 during the melting phase. It was planned to conduct satellite underflights of CryoSat-2 and ICESat-2; however, poor weather conditions meant a lack of opportunities, and this goal was not achieved. Other goals of the 2024 campaign, to coordinate with scheduled field work (e.g. RV Kronprins Haakon servicing an oceanographic mooring in the Amundsen basin) and a separate airborne campaign, the NASA ARCSIX https://espo.nasa.gov/arcsix project, were achieved successfully. We also overflew an array of ice mass balance (CRREL) and weather buoys (UiT) www.cryosphereinnovation.com/data deployed by twin otter landings in April 2024.
