A surface-wave study of the Pacific Ocean basin

T.-l. Teng, C.-h. Chao
1988 Geophysical Journal International  
The average thickness of the oceanic crust is less than 10 km. A few regions in the ocean basin are identified as having a continent-like crust.  ...  The large number of wave paths used permits sufficient resolution in the process of pure-path decomposition.  ...  In this study, we use high-quality digital data from the Global Digital Seismic Network (GDSN) for a large number of events occurring around the Pacific rim.  ...

Turbidity current activity along the flanks of a volcanic edifice: The Mafate volcaniclastic complex, La Réunion Island, Indian Ocean

Aude Mazuel, Emmanuelle Sisavath, Nathalie Babonneau, Stephan J. Jorry, Patrick Bachèlery, Christophe Delacourt
2016 Sedimentary Geology  
The systems are divided in three main domains: deep canyons in the proximal area, a channel network in the medial area, and distal depositional lobes on the abyssal sea floor.  ...  The record of turbidite events in these cores is interpreted in terms of volcanic and climatic changes that could have controlled the sediment transfer to the deep ocean.  ...  Acknowledgements We thank the crew and scientific teams of the 2006 FOREVER and ERODER 1 cruises, the 2008 ERODER 2, the 2010 ERODER 3 and 2011 ERODER 4 cruises for the recovery of a high quality dataset  ...

2016 Acta Oecologica  
Endemic species from the WIO on the average had a larger body size than elsewhere in the tropical Indian Ocean.  ...  Heterogeneous and often unbalanced sampling design, paucity of data in a number of cases, and among-species discrepancy in phylogeographic structure precluded any generalization regarding phylogeographic  ...  The WIO displayed a heterogeneous composition, with the size distribution of endemic species in the EAF being rather similar to that in SWI.  ...

Composition of the Oceanic Crust [chapter]

W.M. White, E.M. Klein
2014 Treatise on Geochemistry  
Large-scale along-axis variations, many of which are related to oceanic islands and mantle plumes, dominate the global variation, particularly in the Atlantic and Indian oceans.  ...  These values almost certainly do not represent the ages of discrete events, but they do demonstrate that chemical heterogeneity in the mantle is old; it is much older than the age of oceanic crust, but  ...
