Sediment sampling with a core sampler equipped with aluminum tubes and an onboard processing protocol to avoid plastic contamination

Tsuchiya, Masashi; Nomaki, Hidetaka; Kitahashi, Tomo; Nakajima, Ryota; Fujikura, Katsunori (2019)

Microplastics are abundant even on the deep-sea floor far from land and the ocean surface where human activities take place. To obtain samples of microplastics from the deep-sea floor, a research vessel and suitable sampling ...

A new small device made of glass for separating microplastics from marine and freshwater sediments.

Nakajima, Ryota; Tsuchiya, Masashi; Lindsay, Dhugal J.; Kitahashi, Tomo; Fujikura, Katsunori; Fukushima, Tomohiko (2019)

Separating microplastics from marine and freshwater sediments is challenging, but necessary to determine their distribution, mass, and ecological impacts in benthic environments. Density separation is commonly used to ...

Survey protocol for seafloor massive sulfied deposits. Revised edition.

Kikawa, Eiichi (Japan Agency for Marine-Earth Science and Technology Project Team for Development of New-generation Research Protocol for Submarine Resources, Yokosuka, Japan, 2018)

A metal deposit is a geological feature in which useful metals have been concentrated to the point of being economically viable for recovery. In other words, in order for a body of rock to be considered a deposit, it must ...

Functional assessment of microbiota in various environments using MAPLE. Version 1.

Japan Agency for Marine-Earth Science and Technology (Japan Agency for Marine-Earth Science and Technology (JAMSTEC), Yokosuka, Japan, 2018)

MAPLE is an automatic system that can perform a series of steps used in the evaluation of potential comprehensive functions (i.e., functionomes) harbored by genomes and metagenomes. From April (2016) through March (2017), ...

How to map the resilience of hydrothermal vent fields: a tutorial. Verson 1.

Japan Agency for Marine-Earth Science and Technology (Japan Agency for Marine-Earth Science and Technology (JAMSTEC), Yokosuka-city, Kanagawa, Japan, 2019)

One of the targets for commercial mining is the Seafloor Massive Sulfides (SMSs) deposits formed around hydrothermal vents, which is a highly attractive source of copper, zinc, lead, gold and silver ores (Hoagland 2010, ...

Onboard bioassay for seawater quality monitoring using delayed fluorescence of microalgae.

Japan Agency for Marine-Earth Science and Technology (Japan Agency for Marine-Earth Science and Technology (JAMSTEC), Yokosuka-city, Kanagawa, Japan, 2017)
