Disappearance of pink-pigmented Globigerinoides ruber at 120,000 yr BP in the Indian and PacificOceans
on the oxygen isotope stratigraphy in 11 Indo-Pacific deep-sea cores, but it continued to live on to the present in the North and South Atlantic Ocean and the Mediterranean Sea. The disparate Atlantic and Indo-Pacific records reflect faunal provincialism
The planktonic foraminiferal species Globigerinoides ruber with pink-pigmented tests occupied a worldwide warm water belt during much of the Pleistocene. This variety was exterminated from the Indian and PacificOceans at about 120,000 yr BP, based

The ethics of place and environmental change : some examples from the SouthPacific
Environment ; Ethics ; Ideology ; Pacific Region ; Place ; Semiotics of space ; Society ; SouthPacificOcean ; Space
This paper concerns place and placelessness, and suggests links between those two and types of environmental ethic. An historical analysis of place based ethics and environmental degradation draws on examples from the Pacific basin. Finally
High resolution (200 yr sample spacing) records of sea surface temperature for the past 15,000 yr have been inferred from planktonic foraminiferal assemblages in a sediment core from the South China Sea. Although the assemblages imply a large
glacial-to-interglacial temperature change, they give no indication of a cooling during Younger Dryas time. This suggests that the Younger Dryas increase in δ18O observed in cores from the equatorial Pacific is not due to a climatic cooling but rather
to a change in the isotopic compositions of the oceans.

Regional sea level change in Northwest Pacific : process, characteristic and prediction
China ; Coastal environment ; Forecast ; Integrated study ; Mathematical model ; North-WestPacificOcean ; PacificOcean ; Regional analysis ; Sea level ; Space time
Based on 22 sparse-distributed tide gauge records in the Northwest PacificOcean marginal sea, the process, characteristic and prediction of regional sea level change are discussed by the integration of 6 mathematic methods. The AA. apply first
-regions from 2001 to 2030. Chinese coast along the Yellow Sea and East China have the largest rise rates. The rate changes near the coast of Japan are a little smaller. Sea level changes along northwest of South China Sea and north of the Yellow Sea
Examen des mécanismes physiques déterminant la variation saisonnière du niveau du nord-ouest de l'Océan Pacifique. Evaluation de la contribution des effets stériques, des marées et statiques de la pression atmosphérique et du bilan radiatif.
Present-day tectonic concepts of events on the western paleo-Pacific lithosphere must be assessed relative to new data. Three problems, fracture zones versus transform faults, the formation of fracture zones, and hotspots versus leaky fracture zones
, are the focus of this paper and are explained using different methods. A case study of the Mid-Pacific Mountains (MPM) is presented to demonstrate a possible tectonic framework for the formation of rises, plateaus, or vortex structures at the orthogonal
cyclones particulièrement intenses a augmenté entre 1991 et 2010. À l'Ouest de 170°E, le rôle de la température de surface de l'océan apparaît décisif, alors qu'à l'Est de ce méridien c'est la circulation atmosphérique qui commande le plus l'activité
