Macrozooplankton and Micronekton off Hokkaido Island, Japan: Composition and Gear Inter-calibration

The second micronekton inter-calibration experiment (MIE-2) was carried out in the coastal area off southeastern Hokkaido Island, Japan, during September 23–October 3, 2005. Comparative tows were made at four stations situated over the upper continental slope with bottom depths of approximately 500 m (Fig. 3.1). This area is strongly influenced by the coastal branch of the Oyashio Current (Kono...

Age and growth of marbled sole Pleuronectoes yokohomae in Kikonai Bay, Hokkaido, Japan

Age and growth of marbled sole Pleuronectes yokohamae werer estimated from growth increments in otolith. The samples were collected with commercial set nets and an experimental bottom trawl net in Kikonai Bay and the nearby waters, southern coast of Hokkaido, from May 1994 to July 1995. Monthly changes in the percentage occurrence of oltoliths with translucent edge in one band and the marginal ...

Dispersion of radiocesium-contaminated bottom sediment caused by heavy rainfall in Joso City, Japan

A large-scale heavy rainfall disaster occurred in Joso City, Japan, in September 2015, and one third of the city area (40 km2) was flooded by the Kinu River. Artificial radionuclides such as 134Cs and 137Cs were known to have accumulated in the river bottom sediment after their release in the 2011 Fukushima Dai-ichi Nuclear Power Plant accident. It was thought that these radionuclides might hav...
