Stratification potential-energy anomaly index standardized by external tide level
Autor: Takaharu Hamada, Sangyeob Kim
Publikováno v: Estuarine, Coastal and Shelf Science. 250:107138
Simpson's stratification index φ is widely used in oceanography as an index of vertical stratification. However, the use of φ can be problematic when the tidal amplitude is significant compared to the water depth, since φ fluctuates periodically w

Long term variation in transparency in the inner area of Ariake Sea
Autor: Kazunori Maeda, Yuichi Hayami, Takaharu Hamada
Publikováno v: Estuarine, Coastal and Shelf Science. 163:290-296
This study analyzed the long time record of transparency (Secchi disk depth) in the inner area of Ariake Sea and determined the reason for the change. The data observed by the Saga Prefectural Ariake Fisheries Research and Development Center for 38 y

Publikováno v: Journal of the Marine Biological Association of the United Kingdom. :1-9
The life history of the Japanese sternaspid polychaeteSternaspis costatavon Marenzeller, 1879 was investigated in the inner part of Ariake Bay from May 2010 to May 2011, with additional sampling in July and September 2011. All the worms were measured

Effect of nutrient concentration and salinity on diel vertical migration ofChattonella marina(Raphidophyceae)
Autor: Souichi Yamaguchi, Toshiya Katano, Masumi Koriyama, Yuichi Hayami, Takaharu Hamada, Kenji Yoshino, Makoto Yoshida
Publikováno v: Marine Biology Research. 10:1007-1018
Vertical migration plays an important role in the development of Chattonella populations in the natural environment; however, this behaviour has remained largely undescribed. In the present study, the diel vertical migration of Chattonella marina in

Environmental monitoring using small fishing boats in Ise Bay for fishery management
Autor: Hiroshi Tachi, Shigeru Tabeta, Kimitoshi Iwaba, Takuya Maruyama, Takaharu Hamada
Publikováno v: Estuarine, Coastal and Shelf Science. 228:106387
It is important to understand and predict fish behavior to assess the impacts of coastal development on ecosystems and to conduct appropriate fishery management. Fish dynamics models have been developed to consider the migration, growth, and populati

Density and undrained shear strength of bed sediment from ND-CPT
Autor: Takaharu Hamada, Takenori Hino, Mitsugu Yoshimura, Jinchun Chai, Rui Jia
Publikováno v: Ocean Dynamics. 63:507-517
The density and the undrained shear strength (s u) of bed sediments at either side of the Isahaya Bay dike in the Ariake Sea, Japan, were investigated using nuclear density cone penetration tests (ND-CPTs). The nuclear density cone penetrometer (ND-C
