Scouting Craton's Edge in Paleo-pacific Gondwana
The geology of the ice-covered interior of the East Antarctic shield is completely unknown; inferences about its composition and history are based on extrapolating scant outcrops from the coast inland. Although the shield is clearly composite in nature, a large part of its interior has been represented by a single Precambrian block—termed the Mawson block—that includes the ArcheanMesoproterozoi...

The Larsemann Hills range is an ice-free oasis on the Ingrid Christensen Coast of Princess Elizabeth Land, East Antarctica, which includes Bharti Island, Fisher Island, McLeod Island, Broknes Peninsula, Stornes Peninsula, and several other islands, promontories, and nunataks. The Larsemann Hills is an ice-free area of approximately 50 km2, located halfway between the Vestfold Hills a...
متن کاملResearch Proposal
Introduction: The California Coastal Sediment Management Workgroup (CSMW) has requested proposals from the U.S. Geological Survey (USGS) Western Coastal and Marine Geology Team (WCMG) to evaluate the transport and fate of fine sediments discharged into California coastal waters. The rationale for this proposed work is a need to better understand the environmental consequences of beach nourishme...
متن کاملThe seismic structure of Precambrian and early Palaeozoic terranes in the Lambert Glacier region, East Antarctica
The Lambert Glacier region of East Antarctica encompasses the proposed boundary between three of the ancient continents that formed East Gondwana: Indo-Antarctica, the central East Antarctic Craton and a proposed extension of the Pinjarra Orogen of Australia. The only area of extensive rock exposure in central East Antarctica, it uniquely allows the seismic structure to be linked to surface geo...
متن کاملPredicting and Mitigating Dredging DispersionImpact: A Case of Phuket Port, Thailand
Dredging activities inevitably cause sediment dispersion. In certain locations, where there are important ecological areas such as mangroves or coral reefs, carefully planning the dredging can significantly reduce negative impacts. This article utilizes the dredging at Phuket port, Thailand, as a case study to demonstrate how computer simulations can be helpful to protect existing coral reefs. ...
