CRYPTIC DIVERSITY IN PLANKTIC FORAMINIFERA IN THE NORTHWEST PACIFIC OCEAN

The Journal of Foraminiferal Research, 2009
Recent molecular studies show multiple cases of cryptic diversification in planktic foraminifera; however, the geographic distribution of the cryptic species is poorly known. Herein, we present the first insight into the cryptic diversity of planktic foraminifera from Northwest Pacific samples.

Simulation and Analysis of Ocean Wave in the Northwest Pacific Ocean

Applied Mechanics and Materials, 2012
In order to obtain more accurate results than the traditional method of wave statistics，the third-generation ocean wave model WAVEWATCH III (WW3) is applied to simulate the sea wave field of the Northwest Pacific. The model is driven by the QSCAT/NCEP blended winds. Then wave parameters are analyzed by statistical analysis method. The comparison of the

Acidic Ocean Hits Pacific Northwest

Chemical & Engineering News Archive, 2013
The path to Cape Flattery is a twisty, moss-carpeted tunnel underneath red cedar and Douglas fir trees that crowd Washington state’s rugged coastline.

Argo data assimilation in ocean general circulation model of Northwest Pacific Ocean

Ocean Dynamics, 2012
The Argo temperature and salinity profiles in 2005–2009 are assimilated into a coastal ocean general circulation model of the Northwest Pacific Ocean using the ensemble adjustment Kalman filter (EAKF). Three numerical tests, including the control run (CTL) (without data assimilation, which serves as the reference experiment), ensemble free run (EnFR ...

An immense shield volcano within the Shatsky Rise oceanic plateau, northwest Pacific Ocean

Nature Geoscience, 2013
Most oceanic plateaux are massive basaltic volcanoes. However, the structure of these volcanoes, and how they erupt and evolve, is unclear, because they are remote and submerged beneath the oceans. Here we use multichannel seismic profiles and rock samples taken from Integrated Ocean Drilling Program core sites to analyse the structure of the Tamu ...

Mid-ocean-ridge basalt of Indian type in the northwest Pacific Ocean basin

Nature Geoscience, 2009
Since 42 million years ago, the northwestern Pacific Izu Bonin arc magmas have incorporated lead from subducted Indian-type oceanic crust. This crust probably formed at a now-extinct spreading centre in the Pacific basin that tapped Indian-type upper mantle, suggesting a greater extent for this mantle domain than accepted at present.

NANOOS contributions to understanding ocean acidification in the Pacific Northwest

OCEANS 2010 MTS/IEEE SEATTLE, 2010
NANOOS is coordinating a regional effort to observe the status of ocean acidification in the coastal waters and estuaries of Washington and Oregon. There is strong partnership in this effort between federal and university scientists, as well as strong interest from shellfish growers, tribes, and other stakeholders in the region.

Vertical distribution of bacterial abundance in the northwest pacific ocean

Journal of the Oceanographical Society of Japan, 1990
Mixed populations of free-living marine bacteria were collected at depths from the surface to the bottom (1,960m in Suruga Bay and 1,585 m in the Japan Sea) in the northwest Pacific during deep-sea diving by the submersible,Shinkai 2000. Their abundance in total cell counts and in lipopolysaccharide (LPS) concentration was found to decrease with ...

Spatial coherence measurement of sound in the northwest Pacific Ocean

The Journal of the Acoustical Society of America, 1993
An experiment on the transverse horizontal spatial coherence of sound propagating in the ocean was performed jointly by Chinese and Russian acousticians in the northwest Pacific Ocean in June 1990. Three hydrophones with spacings of 270 and 130 m were put in the water at a 30-m depth.

Glacial‐age hydrography of the far northwest Pacific Ocean

Paleoceanography, 1998
Stable isotope data on benthic foraminifera from more than 30 cores on the northern Emperor Seamounts and in the Okhotsk Sea are synthesized in paleohydrographic profiles spanning the depth range 1000–4000 m. Holocene (core‐top) benthic foraminiferal δ18O and δ13C data are calibrated to modern hydrographic properties through measurements of δ13C of ...
