Since the possibility of reducing global warming by spraying iron into the Antarctic Ocean was proposed, iron-spraying experiments have been conducted 13 times in these marine areas, and the scientific verification of the hypothesis of iron limitations in the production of marine phytoplankton has made progress. Many of the results obtained suggest that the CO2 absorption effect in the oceans due to the spraying of iron is less than first expected, but there are plans by venture companies to spray iron and the building of an international management system is underway.

Lessons from the Canary Islands Particularly Sensitive Sea Area (PSSA)
Takahiro AsanoAdministrator and Overseas Researcher,National Personnel Authority, Japan / On temporary dispatch to the Maritime Safety and Rescue Agency, Spain
The Canary Islands Particularly Sensitive Sea Area�E�ESSA�E�does more than just protect the natural marine environment; it conserves fish stocks and tourism resources, promotes the integrated management of the land areas of offshore islands and the ocean spaces around them, and contributes to the strengthening of the maritime rescue and coast guard systems all with potentially important policy lessons for Japan. Making conservation of the marine environment our bridgehead, what should we aim for in designating a PSSA? There is a need to reconsider PSSA as a strategic means for realizing ocean governance.

A Dolphin SOS: Cambodia's Dolphins Threatened by Extinction
Keiichi IwashigeDirector, HAB Research Center/Student, Graduate School of Marine Science and Technology, Tokyo University of Marine Science and Technology
An endangered species of dolphin lives in the Mekong River system of Cambodia, but it is again facing a serious threat from overfishing and rampant illegal fishing. Over the past 10 years, with the cooperation of a Japanese civic group, efforts to protect the dolphins and promote nature tourism have increased, but the return of illegal overfishing is now seriously endangering the Mekong Dolphin.
