Springer, Victor G. Pacific Plate Biogeography, with Special Reference to Shorefishes. Smithsonian Contributions to Zoology, number 367, 182 pages, 65 figures, 5 tables, 1982.—It is the thesis of this study that the Pacific lithospheric plate (Pacific Plate) forms a major subunit of the Indo-Pacific biogeographic region. This thesis is defended on two primary grounds: the sharp decrease in numb...

The linear temperature trend of the last 40 yr (1955–94) in the upper Pacific Ocean above 400 m is studied using an objectively analyzed dataset and simulations of an ocean general circulation model. Both the data and simulations suggest a warming trend in the western tropical Pacific (108S–108N) near the surface and in the eastern tropical Pacific above 400 m but a cooling trend in the thermoc...

The pronghorn spiny lobster, Panulirus penicillatus, is a circumtropical species which has the widest global distribution among all the species of spiny lobster, ranging throughout the entire Indo-Pacific region. Partial nucleotide sequences of mitochondrial DNA COI (1,142-1,207 bp) and 16S rDNA (535-546 bp) regions were determined for adult and phyllosoma larval samples collected from the East...

Post-hatchling loggerhead turtles (Caretta caretta) in the northern Pacific and northern Atlantic Oceans undertake transoceanic developmental migrations. Similar migratory behaviour is hypothesized in the South Pacific Ocean as post-hatchling loggerhead turtles are observed in Peruvian fisheries, yet no loggerhead rookeries occur along the coast of South America. This hypothesis was supported b...

Pacific salmon are among the dominant fish in the epipelagic layer of the subarctic Pacific Ocean and are considered the principle consumers of forage resources. In recent years (1990s and 2000s) most Pacific salmon stocks have increased two-fold in abundance. Many researchers consider that such high abundance may increase interspecific competition for food and influence density-dependent facto...

[1] In this paper, we found that the Atlantic Multidecadal Oscillation (AMO) can contribute to the Pacific Decadal Oscillation (PDO), especially the component of the PDO that is linearly independent of El Niño and the Southern Oscillation (ENSO), i.e. the North Pacific Multidecadal Oscillation (NPMO), and the associated Pacific/North America (PNA) pattern. Using a hybrid version of the GFDL CM2...

Over the last century, northeast Pacific coastal sea surface temperatures (SSTs) and land-based surface air temperatures (SATs) display multidecadal variations associated with the Pacific Decadal Oscillation, in addition to a warming trend of ∼ 0.5-1 °C. Using independent records of sea-level pressure (SLP), SST, and SAT, this study investigates northeast (NE) Pacific coupled atmosphere-ocean v...

Pacific Economic Bulletin Volume 24 number 1 2009 © the australian national university New ways of measuring corruption are being used to assess the performance of governments in tackling the problem. The Pacific Islands Plan, for example, envisages a ‘control of corruption (integrity) indicator’ that could be used to assess a government’s progress towards achieving good governance (Pacific Isl...

[1] The Pacific Ocean likely exerted the greatest marine influence on climate during the greenhouse interval of the Paleogene. The first step toward assessing the role of Pacific deepwater circulation in global heat transport is a comprehensive reconstruction of deepwater mass composition and circulation patterns. We present new deepwater mass Nd isotope data from ODP Leg 199 Sites 1215, 1217, ...

6 [1] Decadal changes of persistence barriers in various indices of sea surface temperature 7 (SST) and ocean heat content (OHC) are examined in this study using observations and 8 ocean data assimilation products for the period 1958–2001. It is found that the SST 9 indices in the eastern and central equatorial Pacific exhibit very different decadal 10 barrier variability. The variability is la...
