Use of renewable forms of marine energy resources such as offshore wind farms showed a remarkable advance in Europe in the last half of this century’s first decade, and has now accumulated 10 years’ worth of many types of knowledge and know-how regarding investigations and assessments of environmental impacts. Keeping these European conditions in mind, I would like to explore how we should think about impacts on marine life and habitats as we begin to promote offshore wind farms in ocean areas around Japan.

The hydrogen ion concentration scale (pH) is a chemical index used to specify acidity and base properties of a water-based solution. It is difficult to accurately determine the pH of seawater. The authors have developed a pH sensor based on a new concept, and placed third in an international pH sensor competition held since 2013. The new pH sensor is now contributing to ocean acidification research from the north to the south poles.

In recent years the “Ama,” or women breath-hold divers, have been held up as a model for sustainable fisheries. Although having no previous experience, the author began Ama breath-hold diving on moving from Nagoya to Ijika in Toba City at the time of her marriage. While the work of an Ama involves one difficulty after another, it teaches you how to live and about the fascinations of the sea. I would like to tell here of the appeal of the Ama life and how it is lived.
