Nortek Japan G.K.

Nortek designs, develops and produces scientific instruments that apply the Doppler principle to underwater acoustics in order to measure water in motion, such as currents and waves.

We provide truly innovative, robust, and accurate instruments, backed up by advanced software and comprehensive support to ensure customers maximize value from their measurements.

Our solutions make a big difference.

These instruments are used by scientists, researchers and engineers at renowned institutions and government agencies worldwide. They are employed in demanding environments that require state-of-the-art instrumentation that is reliable and easy to use.

Our exploratory devices help cast light on the workings of the world’s oceans, which occupy vast swathes of the planet, but are still little understood.

Most of Nortek’s technology is based on a scientific physical principle called the Doppler effect. This relates to the change in frequency (or pitch) when a sound source moves with respect to an observer.

By measuring these changes in frequency/phase, our instruments accurately measure profiles of speed and direction of complex water motion.

Nortek’s product portfolio ranges from wave measurement systems to single-point turbulence sensors and oceanic current profilers. Our product range covers four themes: ocean waves, ocean currents, turbulent flow and subsea navigation.

Our objective is to excite users with useful, innovative technology underpinned by oceanographic science and research. We work systematically with quality and are certified by leading quality assurance organizations.

JAMSTEC Research Institute for Marine Geodynamics

◆Illuminating Earthquakes and Volcanic Activities for Disaster Mitigation

To reveal earthquakes and volcanic activities, the scientists and staff of the Research Institute for Marine Geodynamics will conduct large-scale observations around Japan and the western Pacific using JAMSTEC vessels and various state-of-the-art marine exploration technologies. In particular we will conduct geophysical-geological surveys in the Nankai Trough, Japan Trench, Kuril Trench, and other tectonically active zones that may be subject to a forthcoming megathrust earthquake or volcanic eruption. Moreover, we will develop, improve, and upgrade the methods and systems to acquire and process data.
Furthermore, in line with SDGs 11 (sustainable cities and communities), our institute will contribute to disaster mitigation by sharing the scientific knowledge we have gained with society. We will also endeavor to conduct observational surveys and apply our research results in countries that are vulnerable to frequent natural disasters such as earthquakes, tsunamis, and volcanic activities.

Science of Slow Earthquakes

"Science of Slow Earthquakes" is... 

"Science of Slow Earthquakes" is a five-year collaborative project conducted by researchers in Japan.

It aims to reveal a new type of seismic phenomena defined as "slow earthquakes" from a new multidisciplinary perspective incorporating geophysics, geology, and non-equilibrium physics.

Database

Slow earthquake database
The database provides various catalogs of slow earthquakes. A number of catalogs were compiled into a standardized format. As of February 2021, the repository consists of over 70 catalogs.

Goechemical Society of Japan

The Geochemical Society of Japan
Geochemical Society of Japan (GSJ) is a scientific organization of geochemistry and cosmochemistry field with over 900 members. The GSJ has been established in 1953 with 200 members and has re-started as a general incorporated association since 1st of November 2017.
The GSJ has published an international journal, “the Geochemical Journal (GJ)” and a Japanese journal, “Chikyu-Kagaku (Geochemsitry)” since 1966 and 1967, respectively. The GJ was the first SCI journal of Earth Science field in Japan, indicating that the members of early GSJ had an ambition to stand at the international community of earth science.
The GSJ has tried to build up the cooperative and constructive relations with researchers worldwide by not only the publication of international journal but also the cooperation with international academic groups of geochemistry and cosmochemistry. We have engaged MOU with Chinese Society for Mineralogy, Petrology and Geochemistry (CSMPG), Geochemical Society (GS), European Association of Geochemistry (EAG), and Geological Society of Korea (GSK). We have exchanged the scientists through annual meetings with CSMPG and GSK. We also support the Goldschmidt Conference as a co-sponsor.
The GSJ will intensely continue to contribute to the field of geochemistry and cosmochemistry throughout the scientific and human exchange programs.


Geochemical Journal
Geochemical Journal is an international peer-reviewed journal devoted to original research papers in geochemistry and cosmochemistry. It is the primary journal of the Geochemical Society of Japan. Areas of research are as follows:

• Cosmochemistry
  Mineralogy, Petrology, and Rock Chemistry
  Volcanology and Hydrothermal Chemistry
  Isotope Geochemistry and Geochronology
  Atmospheric Chemistry
  Hydrology and Marine Chemistry
  Organic Geochemistry
  Environmental Chemistry
