In December 1975, the British Antarctic Survey embarked on an 8-week long survey observing the proposed theory of Astraea Nunatak and Ceres Nunataks having an aeromagnetic connection between one another. I. A. Crawford and R. W. Girdler embarked on the survey, along with other accompanists and personnel members, flying at a constant barometric altitude of approximately 1130 meters. The equipment used included a Geometrics G-803 proton precision magnetometer with both analogue and digital recording, a Bendix DRA-12 Doppler navigation system and Sperry C-12 gyro-magnetic compass, and a Bonzer radio altimeter. Overall, the 2-month long survey was a successful event and contributed to the history of Alexander Island and the Antarctic Peninsula in itself. Former contributors to this survey include:
Barker, P. F. - Studied the Cenozoic subduction history of the Antarctic Peninsula region.
Bell, C. M. - Observed the geology of the southern portion of Alexander Island.
Bhattacharyya, B. K. - Examined the magnetic anomalies due to prism-shaped bodies with arbitrary polarization.
Burn R. W. - Studied multiple fields of Alexander Island, such as the early Tertiary calc-alkaline volcanism on the island and researching the geology of the nearby LeMay Mountain Range due 40-50 kilometers north of Staccato Peaks.
Care, B. W. - Like Burn, Care studied the vast majority of fields involving Alexander Island, such as archiving geographic reports on the Havre Mountains, Lassus Mountains and other miscellaneous peaks within the vicinity of northern Alexander Island.
Coles R. W. - Conducted two magnetic interpretation methods using rectangular prisms.
Collinson, D. W. - Created an anisotropic susceptibility meter, along with Molyneux, L. and Stone, D. B.
Crawford, I. A. - Proposed an analysis of aeromagnetic data over the Staccato Peaks region of Alexander Island, Antarctica, along with Girdler, R. W.
Edwards, C. W. - Collected early Mesozoic marine fossils from the central portion of Alexander Island.
Fabiano, E. B. - Observed grid values of total magnetic intensity, along with the help of former geophysicist Peddie, N. W.
Pankhurst, R. J. - Studied the geochronology of Graham Land, Antarctica.
Peddie, N. W. - Former geophysicist of BAS.
Renner R. G. B. - Former member of BAS and accepted the aeromagnetic survey to commence, chief of the 1975 survey.
Smellie, J. L. - A complete arc-trench system recognized in Gondwana sequences of the Antarctic Peninsula region.
Streckeisen, A. - Gave to each plutonic body its proper name.
Suarez, M. - Credited for having charted a Plate-tectonic model for the southern portion of the Antarctic Peninsula and its relation to the southern Andes Mountain Range.
