Observational evidence is presented to show an atmospere-ocean coupled system in the maturing process of the Asian summer monsoon (ASM) and the western Pacific monsoon (WPM). The ASPM and WPM are characterized by 4 abrupt seasonal changes
western Pacific (SWP) lags behind those in the Indian Ocean by about one month.
that exhibit phase-locking features in the annual cycle. Over the Indian Ocean, the seasonal increase of sea surface temperature (SST) follows the solar insolation and reduced evaporative cooling as well. In contrast, increase of SST over the subtropical
Stable isotopes, geochemical, lithological, and micropaleontological results from cores from the far northwest (FNW) Pacific and the Okhotsk and Bering seas are used to reconstruct the regional environment for the last glaciation, the deglacial
transition, and the Holocene. During deglaciation, accumulation of the coarse terrigenous component decreased in sediments of the Bering Sea and the FNW Pacific before the north Pacific terminal event T1ANP, probably as a result of rising sea level

The satellite SEASAT is used to derive maps of the sea surface topography in the Pacific and Indian Oceans and to estimate the thickness of the oceanic plates. (P. A. Pirazzoli).
The distribution of radiolarian assemblages identified by Q-mode factor analysis of radiolarian microfossils in surface sediments from low latitudes in the PacificOcean reflects their associations with surface water masses. Downcore fluctuations
of these radiolarian assemblages at two sites, RC10-65 and V19-29, indicate changes in circulation in the eastern equatorial Pacific during the past 500,000 yr. Fluctuations in the importance of upwelling along the coast of Preu and in the Equatorial undercurrent have
The ethics of place and environmental change : some examples from the South Pacific

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

This study presents radiolarian microfossil-based temperature reconstructions for the eastern North Pacific spanning the past 20,000 yr to examine possible correlations and linkages between continental climate change and changes in sea surface

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.

This research examines the 500 hPa circulation patterns that lead to the occurrence of days dominated by anticyclones of Pacific origin (Pacific Highs) over the central Gulf Coast. Although the geographically preferred zones of greatest height
variability are similar to those leading up to days dominated by anticyclones of continental origin (Continental Highs), variability centers on the northern fringes of the extratropics seem to support Pacific High activity to a greater extent than was found
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.
Calculations of surface radiative fluxes in the tropical Pacific show that the distributions of solar and thermal infrared radiation follow closely with cloudiness and, to a lesser extent, humidity. Surprisingly, the distribution of infrared

Twenty deep-sea sediment cores from the western Pacific between 30°N and 30°S provide evidence of sea-surface temperature (SST) changes throughout the tropics and subtropics. The results indicate that a western Pacific warm pool existed during
