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

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.

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

This paper illustrates how studies of the geomorphology of oceanic islands can contribute to the understanding of nearby plate boundaries. For this purpose, an oceanic island is defined as one within an ocean basin. Case studies are given of three

localized rainfall within the inner core region of intense TCs. Sub-basins with intense TCs that produce extreme rainfall rate maxima include the Bay of Bengal, the South Philippine Sea, the East China Sea, the north coast of Australia, southeast Melanesia

The results of calculating the space-time variability of the meridional heat transport (MHT) in the Atlantic, Pacific and Indian oceans are discussed. Initial information contains data on the resultant heat flux at the ocean-atmosphere interface
and the rate of change in the ocean heat content. It is found that the period of heat transport from the South Atlantic to the North Atlantic is nearly twice as large than in the opposite direction. In the other oceans the periods of heat transport from
the Southern Hemisphere to the Northern Hemisphere and inversely are approximately equal. A semiannual MHT harmonic is revealed. It is especially pronounced in the Indian Ocean. - (L'Ed.).
It is found that daily maximum precipitation is higher in monsoon region over the Indian Ocean and the western Pacific. Especially in the western Noorth Pacific, including the southern coastal region of Japan, it exceeds 300 mm in a broad extent
. This region seems to be the world's heaviest rainfall region on a daily time scale when viewed from a macroscopic disribution. The second heaviest region is in the western part of the tropical South Indian Ocean.
