Purpose
The objective of the ACRUP project is to study the structure of the
crust and upper mantle of the Ross Sea region using geophysical measurements
along onshore and offshore transects. The Ross Sea is part of the West Antarctic
Rift system (WRS). The WRS has a 2500 to 5000-m-high rift shoulder
(Transantarctic Mountains (TAM)) on the west, and is underlain in the Ross Sea
by numerous large rift basins now filled with thick sedimentary sections. A deep
sedimentary basin, the Victoria Land basin, and an active rift (Terror rift) are
mapped along the western side of the Ross Sea adjacent to the TAM. The rift
structures of the Ross Sea are believed to have formed initially with the
Mesozoic breakup of Gondwana, and later with late Mesozoic and Cenozoic
extension across the Ross Sea and uplift of the Transantarctic Mountains. The
age of the Mesozoic and Cenozoic rifting is poorly known because rocks from deep
within the rift basins have not been sampled . Also, the crustal structure and
mechanism(s) of rifting are not known because few refraction data exist,
although many models for the evolution of the WRS and uplift of the TAM have
been proposed. The ACRUP experiments are designed to determine deepcrustal
structures in the Ross Sea region to help resolve the mechanisms, and relative
timings, of rifting events.
