Some History

•ANARE surveyor Knuckey observed an Astro fix near Mt Harding in 1958.

•ANARE geological survey party visited Mt Harding region in 1973

•ANARE extended geodetic survey traverse to Austin Nunatak 1974

•Russian airborne geophysical exploration in 1970s and recently in 1998

•Chinese geological and mapping ground expedition from Zhong Shan in 1999

Future Work

•Re-observe geodynamic mark for uplift studies

•Establish additional points for geodetic infrastructure in ITRF2000

•Connect to Chinese or Russian monuments

•Derive transformation parameters between Australian and Chinese datums
