연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

제안 방법

  • The concentrations of 137Cs in sediment and seawater and some physical and chemical properties of sediments were measured in the adjacent sea to Yangnam, Korea to study the deposition properties of 137Cs in marine sediments.
  • In this work, 137Cs concentration, particle size and total organic carbon, hydrogen, nitrogen and sulfur contents of marine sediments were measured. The distribution of 137Cs and the relationship among 137Cs concentration, particle size and organic matter contents of marine sediments were investigated to study the deposition properties of 137Cs in marine sediments collected in the East Sea near Yangnam, Korea. Also 137Cs concentrations in seawater were measured to assess the distribution coefficient of 137Cs.

대상 데이터

  • Marine sediment samples were collected by a grab sampler from 382 locations as shown in Fig. 1. The samples were dried at 90 T, powdered and then sieved to a particle size smaller than 2 mm to guarantee the homogeneity of the samples.
  • Seawater samples were collected at 21 stations, shown in Fig. 1. At each sampling station, surface and subsurface seawater samples were collected by a submersible pump.
  • Sediment and seawater samples were collected in the adjacent sea to Yangnam from 24 June to 24 July 2000, shown in Fig. 1, The deepest seawater depth in the sampling region was 92 m. The temperature of the sampled sediments was in the range of 4.

이론/모형

  • The particle size of the sediment was analyzed for 90 wet sediment samples. The sediments coarser than 63 pm were sieved through a nest of sieves and separated on the basis of particle size using the Wentworth grade classification. The particle size distribution of the coarse fraction was determined from the weight of the separated sediment after drying and the sediments less than 63 pm were analyzed using a Micromeritics SediGraph 5100D Particle Size Analyzer.
