Rapid Variability in the Japan/East Sea: Basin Oscillations, Internal Tides, and Near-Inertial Oscillations
Basin Oscillations Internal Tides
2015/7/24
Many processes contribute to the variations of currents, sea surface height (SSH), and thermocline depth in marginal seas. Energetic examples range broadly over time scales from slow mesoscale and int...
Why do Intrathermocline Eddies Form in the Japan/East Sea? A Modeling Perspective
East Sea Perspective
2015/7/24
Intrathermocline eddies (ITEs) are characterized by a subsurface lens of relatively homogeneous water. By definition, they are situated within the thermocline and therefore split the stratified water ...
East of Korea and West of Japan The Very Model of Modern Major Oceanography
Modern Major Oceanography East of Korea
2015/7/24
The Japan/East Sea* is often described as a miniature ocean, and the characterization is apt. The relatively small basin (about 1000 km by 800 km) spans conditions from subarctic to subtropical and so...
Japan/East Sea Water Masses and Their Relation to the Sea's Circulation
Sea's Circulation Sea Water Masses
2015/7/24
The Japan/East Sea is a major anomaly in the ventilation and overturn picture of the Pacific Ocean. The North Pacific is well known to be nearly unventilated at intermediate and abyssal depths, reflec...
Real-Time Observations of the February 2010 Chile and March 2011 Japan Tsunamis Recorded in Honolulu by the Pacific Islands Ocean Observing System
Honolulu Real-Time Observations
2015/7/17
Continuous monitoring by the Pacific Islands Ocean Observing System (PacIOOS) provided a unique opportunity to study the effects of two tsunamis on the coastal and estuarine waters of Hawai'i. By the ...
DONET: A Real-Time Monitoring System for Megathrust Earthquakes and Tsunamis Around Southwestern Japan
Monitoring System Megathrust Earthquakes
2015/7/17
DONET (Dense Ocean floor Network for Earthquakes and Tsunamis; https://www.jamstec.go.jp/donet/e/index.html) is a cabled seafloor observatory that monitors the Nankai and Tōnankai seismogenic zones, o...
Investigation of the Huge Tsunami from the 2011 Tōhoku-Oki, Japan, Earthquake Using Ocean Floor Boreholes to the Fault Zone
Japan, Earthquake Using Ocean Floor
2015/7/17
Integrated Ocean Drilling Program (IODP) Expedition 343, named the Japan Trench Fast Drilling Project (JFAST), drilled ocean floor boreholes through the fault zone of the 2011 Tōhoku-Oki earthquake (M...
Tree-ring cellulose d18O variability in pine and oak and its potential to reconstruct precipitation and relative humidity in central Japan
tree-ring cellulose d18O pine oak precipitation relative humidity central Japan
2017/4/10
Oxygen isotope ratios (d18O) of tree-ring cellulose in pine (Pinus densiflora) and oak (Quercus serrate and Quercus
variabilis) growing in central Japan from 1970 to 2011 share a common inter-annual ...
Concentration of 134Cs + 137Cs bonded to the organic fraction of sediments offshore Fukushima, Japan
Fukushima Dai-ichi Nuclear Power Plant accident radiocesium sediment organic fraction sequential extraction
2017/4/10
We conducted a sequential chemical extraction experiment for radiocesium (134Cs + 137Cs) using 21 surface sediment
samples and two sets of size-fractionated surface sediment samples collected offshor...
Distribution and supply mechanisms of high uranium concentration in the rivers of Okinawa Island, Japan
uranium river Okinawa Island guideline value supply mechanism
2017/4/10
Uranium concentrations in the rivers of Okinawa Island, Japan were determined in this study. Most rivers in the
southwestern area of the island showed high U concentrations, the highest of which was ...
Application of a global nonhydrostatic model with a stretched-grid system to regional aerosol simulations around Japan
stretched-grid system Japan
2015/3/5
An aerosol-coupled global nonhydrostatic model
with a stretched-grid system has been developed. Circulations over the global and target domains are simulated with
a single model, which includes @...
