The accuracy of satellite-observed sea surface salinity (SSS) was evaluated in comparison with in-situ salinity measurements from ARGO floats and buoys in the seas around the Korean Peninsula, the northwest Pacific, and the global ocean. Differences in satellite SSS and in-situ measurements (SSS errors) indicated characteristic dependences on geolocation, sea surface temperature (SST), and other oceanic and atmospheric conditions. Overall, the root-mean-square (rms) errors of non-averaged SMOS SSSs ranged from approximately 0.8-1.08 psu for each in-situ salinity dataset consisting of ARGO measurements and non-ARGO data from CTD and buoy measurements in both local seas and the ocean. All SMOS SSSs exhibited characteristic negative bias errors at a range of -0.50- -0.10 psu in the global ocean and the northwest Pacific, respectively. Both rms and bias errors increased to 1.07 psu and -0.17 psu, respectively, in the East Sea. An analysis of the SSS errors indicated dependence on the latitude, SST, and wind speed. The differences of SMOS-derived SSSs from in-situ salinity data tended to be amplified at high latitudes (40-60°N) and high sea water salinity. Wind speeds contributed to the underestimation of SMOS salinity with negative bias compared with in-situ salinity measurements. Continuous and extensive validation of satellite-observed salinity in the local seas around Korea should be further investigated for proper use.

Conventional surimi processing from white flesh fish, such as Pacific whiting and Alaska Pollee utilizes only <25％ of the body (Toyoda and others 1992; Park and others 1997). Conventional surimi is refined myofibrillar proteins processed by removing unnecessary foreign materials such as fat, pigment skin, and water soluble sarcoplasmic proteins. The acid-aided process demonstrated excellent gel forming ability for cod and mackerel with extremely higher yield (Hultin and Kelleher 1999). (omitted)

The Magnuson-Stevens Fishery Conservation and Management Act of 1976 mandated the use of a new and radical management approach for fisheries in the United States. Seven fishery management councils were created, one being the North Pacific Fishery Management Council (NPFMC). Each of these Councils was given the responsibility for ensuring the conservation of fishery resources under their jurisdictation. (omitted)

A single specimen of Epinephelus lanceolatus, belonging to Epinephelinae of the family Serranidae, was newly collected from Jeju Island, South Korea, in December 2009. Epinephelus lanceolatus is characterized by anterior lateral-line scales with branched tubules, cycloid scales, irregular white spots, and fins with numerous small black spots. We propose a Korean name, "Dae-wang-ba-ri' for this species.

To study the trafficability on soft and cohesive benthic terrain, a soil bin is designed and constructed. The information of shear strength of pacific seafloor and the results of dimensional analysis of vehicle-train system are used as basic datum for concept design of soil bin. Cohesive benthic terrain is modeled by means of bentonite-water mixture. The shear strength of the mixture is measured by motorized shear meter. Several facilities are constructed for mixing and evening modeled soil, transporting vehicle model. The shear strength in soil bin is investigated for depth, age and velocity. The result of this study is used as basic information to the experiment, study for development of crawler on benthic terrain.

북서태평양의 해수순환을 원시방정식 수처모형을 이용하여 재현하여 알라스카 만에서 관측된 해수순환의 경년변화에 대한 설명을 시도하였다. 모형 결과에 의하면 알라스카 gyre의 계절적 위치 변동은 없으며, 관측된 경년변화는 중규모 와류가 역학심도 계산에 영향을 미친 결과로 보인다. 이러한 중규모 와류는 수온 염분 관측, 부표추적 실험, 그리고 인공위성에 의한 해수면 관측에서도 관측되었다.

The National Fisheries Research and Development Institute (NFRDI) conducted a circle hook experiment to compare the catch rates of target and bycatch species between J hook and circle hooks in the tuna longline fishery of the Eastern Pacific Ocean, which is located between $9^{\circ}13'S-1^{\circ}36'N$ and $126^{\circ}00'-138^{\circ}21'W$. Sampling was conducted from September 20 to October 23, in 2006. In this survey, we collected shark data to obtain the ratio of fin weight to body weight of sharks. Overall, 413 sharks belonging to 9 species were caught on 62,464 hooks. The total weight of the sharks caught was 11,093 kg. The ratio of wet fin weight to body round weight of sharks by species ranged from 3.7% to 7.7%, while the mean was 5.4%. The total ratio of wet fin weight to the dry fin weight of sharks ranged 0.38 to 0.70 and the mean value was 0.53. The ratio of dry fin weight to the body round weight of the sharks was estimated to be 2.86%.
