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

La modélisation des interactions océan-atmosphère sur le Pacifique équatorial a toujours sous-estimé la température de surface de l'océan et rendu très imparfaitement compte des caractéristiques de la thermocline. L'A. propose diverses améliorations
Disappearance of pink-pigmented Globigerinoides ruber at 120,000 yr BP in the Indian and PacificOceans
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
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 purpose of this research is to illustrate the utility of using a 3D grid system in locating and describing any possible mid-ocean landslides and slumps.
Observations of flexure and the geological evolution of the PacificOcean basin
The response of the Pacific plate to oceanic island and seamount loads has been used to estimate the distribution of ridge crest and off-ridge volcanism on the plate since the late Jurassic. The most extensive event, forming the Hess rise, Line
Islands ridge, Necker ridge, and Robbie ridge, occurred on the Pacific/Farallon and Pacific/Phoenix ridge crests during the interval 90-120Myr BP (Barremian to Turonian). This event, which extended over a much larger area than comparable volcanism
In this study, a comparison is made between orbital forcing and Pacific sea surface temperature (SST) forcing of the monsoon through a sequence of atmospheric general circulation model experiments configured for 6,000 and 9,000 yr B.P. The results
imply that SSTs are potentially as important as orbital parameters in governing the monsoon and that more data , particularly from the equatorial Pacific, are crucial to deciphering Holocene climate.
