New ground-based gravity and GNSS data set collected at nine sites along a ~14 km transect across the Denman Glacier system during the Denman Terrestrial Campaign 2023/24. The survey was conducted along the existing ICECAP airborne geophysical flight line ASB/JKB2c/Y11b, enabling direct comparison between ground-based and airborne observations. Coincident GNSS observations are provided for precise station positions and ellipsoidal heights.

The Denman Marine Voyage (DMV) brought together researchers from the Australian Antarctic Program Partnership (AAPP – AAS4631, Chief Investigator Dr Laura Herraiz-Borreguero), the Australian Centre for Excellence in Antarctic Science (ACEAS – AAS4630, Chief Investigator Prof. Matthew King), Securing Antarctica’s Environmental Future (SAEF – AAS4628, Chief Investigator Prof. Steven Chown), and the Australian Antarctic Division (AAD – AAS4636 and 4556 Chief Investigators Dr So Kawaguchi and Dr Leonie Suter), on a highly collaborative, multidisciplinary research voyage aboard RSV Nuyina to the Denman Glacier region and Shackleton Ice Shelf. The voyage was the first dedicated marine science voyage for RSV Nuyina and represented a significant milestone for the Australian Antarctic Program. This voyage report provides information for the voyage including: - Voyage summary and itinerary - Weather conditions during DMV - Participant list (science team, technicians, media team, medical team, ship crew) - High level science objectives for each of the parties onboard (AAD, AAPP, ACEAS, SAEF) - Individual reports for each scientific working group onboard (background, objectives, methods, report on activities, preliminary results (where relevant)), data management plans, acknowledgements, references) - Media program - ACEAS Outreach - Appendix, with Supplementary Material to be separate to the main report.
