High fish abundance in the confluence of two large rivers in the Amazon

Ryota and his team report a high fish larvae abundance in the confluence zone between black and white water rivers in the Amazon River system. In the center of the Amazon River basin, white water of the Amazon River meets with black water of the Negro River, creating a conspicuous visible boundary spanning over 10 km along […]

Zooplankton community changes over monsoons

Ryota and his colleagues investigated zooplankton community in a coral reef of Malaysia . The research team collected copepods with a plankton net over different monsoonal periods. They found that more than 70% of the community was dominated by small copepods throughout the year, and the species composition varied with seasonal monsoons. The research team considers that differences […]

Sea-surface microlayer is rich in microbes over coral reefs

Do you know the sea-surface microlayer? The sea-surface microlayer is the thin boundary layer between the atomosphere and ocean, with a typical thickness of 10-250 µm. It is also called ‘surface film’ or ‘surface skin’. The sea-surface micolayer is generally enriched in both dissolved and particulate organic matters and microbes. The sea-surface microlayer can be […]

What happens after drilling the deep-sea floor?

Ryota and his team monitored the benthic ecosystem at 1,060 m depth of hydrothermally active areas in the Okinawa Trough, off Japan, where a scientific drilling by the Deep Sea Scientific Drilling Vessel Chikyu was performed on September 2010. This monitoring was started before the drilling operation and lasted 40 months thereafter. As a result, it […]

Typhoon enhances the production of bacteria and phytoplankton

Kenji Tsuchiya and his colleagues investigated responses of bacteria and phytoplankton to physical-chemical environments induced by typhoon passages. The study showed that the passage of typhoon Malou in a coastal water of Japan in 2010 caused an abrupt decline of salinity and a large increase in the amount of nutrients, immediately enhancing bacterial production. The study also sowed that […]

The first multi-hectare scale 3D survey of a deep-sea vent community

Blair Thornton and his colleagues investigated the distribution of megabenthos over multi-hectare regions (2.5 ha) of the seafloor of a deep-sea hydrothermal vent site off Japan for the first time. The study region was the target of scientific drilling during the IODP Expedition 331 in 2010. The research team surveyed biomass of megabenthos using high- and […]
