“…There are 41 sigma-z levels with denser levels in the upper water column to better resolve the upper ocean. EASNFS analysis has been previously applied for several studies in the western North Pacific, e.g., the currents in the Korea/Tsushima Strait (Jacobs et al 2005;Teague et al 2006), transports in the Gulf of Papua (Keen et al 2006), impact of typhoons on the upper ocean temperature , and thermal structures in South China Sea (Chang et al 2010). We used the first 8 years (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010) of the EASNFS reanalysis product in this study.…”

The relationship between the Kuroshio volume transport east of Taiwan (~24°N) and the impinging mesoscale eddies is investigated using 8-year reanalysis of a primitive equation ocean model that assimilates satellite altimetry and SST data. The mean and fluctuations of the model Kuroshio transport agree well with the available observations. Analysis of model dynamic heights and velocity fields reveals three dominant eddy modes. The first mode describes a large eddy of~500 km in diameter, centered at 22°N. The second mode describes a pair of the north-south counter-rotating eddies of~400 km in diameter each, centered at 23°and 20°N, respectively. The third mode describes a pair of the east-west counter-rotating eddies of~300 km in diameter each, centered at 21°N. The associated velocity fields indicate eddies extending to 600-700 m in depth with vertical shears concentrated in the upper 400 m. All three modes and the model Kuroshio transport have similar dominant timescales of 70-150 days and generally are coherent. The decreased Kuroshio volume transports typically are associated with the impinging cyclonic eddies and the increased transports with the anticyclonic eddies. Selected drifter trajectories are presented to illustrate the three eddy modes and their correspondence with the varying Kuroshio transports.

“…Three hourly surface heat flu xes, solar radiat ion, wind stresses, and sea level air pressure fro m NOGAPS/ FNMOC are used for surface forcing [10]- [11]. Open boundary conditions (BC), including sea surface elevation, transport, temperature, salin ity and current, are based on average monthly climate values fro m 2003 through 2009 provided by the East Asian Seas Ocean Nowcast/ Forecast System (EASNFS) of the Naval Research Laboratory [12]- [15]. Barotropic t idal forcing is applied to the open boundary grid by superimposing tidal elevation and transport for 11 tidal constituents (M m , M f , K 1 , O 1 , P 1 , Q 1 , K 2 , M 2 , N 2 , S 2 , and M 4 ) on the (non-tidal) BC fro m EASNFS using a forced radiat ion BC.…”

S tate-of-the-Art noise prediction has been used to model noise emissions from industrial facilities, shipping activity in underwater environment to estimate noise level contours beyond the source area, and to determine specific impacts at potentially sensitive receptors, including marine mammals, etc. This paper presents the ambient noise modeling using adiabatic mode theory as acoustic propagation model to evaluate the noise statistics including temporal coherence and spatial variability offshore western Taiwan. In this model, the ocean model (Taiwan Coastal Ocean Nowcast/Forecast S ystem, TCONFS , formulated on the basis of the Princeton Ocean Model) generating time varying/spatial dependent temperature profiles for water column variability, and geo-acoustic database are used as environmental inputs to this model. The modeling results demonstrate the temporal/spatial variability induced by time varying ocean model output, manifested by measured data.

“…It is connected to the adjacent ocean by shallow straits. Warm water originating from a branch of the Kuroshio Current, which is a strong warm current in the western North Pacific Ocean, flows into the East/ Japan Sea through the Korea/Tsushima Strait and flows out through the other straits (Cho and Kim, 2000;Kim et al, 2001;Taegue et al, 2006;Na et al, 2009). The Northwest Pacific Ocean, especially the East/Japan Sea, the East China Sea, and the Kuroshio Current, are the most rapidly warming marine environments in the world (Belkin, 2009).…”

The geographical distribution of the toxic blue-lined octopus (commonly known as the blue-ringed octopus), Hapalochlaena spp., around the East/Japan Sea was investigated. Observation records of the octopus were gathered using commercial search engines on the Internet. A questionnaire to complement and enhance the base data was conducted that targeted fishermen from areas where the octopus was most likely to occur, i.e., the southeast coast and islands of Korea in the East/Japan Sea. Overall, 32 observational records of the blue-lined octopus were found from Korea and Japan. In Korea, only one record, from 2003, was found on a website; none of the 240 fishermen who participated in the questionnaire reported seeing blue-lined octopus. However, a total of 31 observations of the blue-lined octopus from 2004 to July 2010 were found from 17 different regions in the East/Japan Sea and neighboring waters in Japan. Twenty-two cases were from coastal Honshu Island, and nine were from the west coast of Kyushu Island, Japan. The northern distributional boundary of the blue-lined octopus on the Japanese coast was off Fukui Prefecture around latitude 36º10' N. Our results indicate that the blue-lined octopus is distributed extensively along the Japanese coast, at a low frequency, in the East/Japan Sea.
