Since the return of the St. George Expedition from the Pacific in 1925, a series of nine papers (2–8, 26, 27), describing the geology of most of the volcanic islands visited, has been published, and it is now possible to co-ordinate the results already arrived at, and to use them in an attempt to throw light on the structure of the Pacific basin.

ABSTRACT A series of seismic refraction profiles has been made across a flat bank at Gardner Pinnacles (a pair of volcanic islets on the western Hawaiian Ridge) down the side of the ridge and across the adjacent deep to the floor of the Pacific basin. The ridge is composed principally of material with velocities typical of volcanic islands. The high-velocity oceanic crust, found in the oceanic areas adjacent, extends beneath the ridge and up into the center of the rise. The total crustal section is thickened and the Mohorovičić discontinuity depressed beneath the deep as well as beneath the ridge. The smooth “archipelagic apron” on the north side of the ridge has at most 20 meters of sediment over a layer with a velocity of 3 km/sec, which could be volcanic and is definitely of higher velocity than normal oceanic sediments.

Abstract The Pacific rat, R. exulans, is an major agricultural and environmental pest in parts of Southeast Asia and the Pacific. Thought to have spread with Polynesian colonists over the past several thousand years, it is now found through much of the Pacific basin, and is extensively distributed in the tropical Pacific. It poses a significant threat to indigenous wildlife, particularly ground-nesting birds, and has been linked to the extinction of several bird species. R. exulans may also transmit diseases to humans.
