Title:
METHOD FOR SUPPRESSING MARINE ACIDIFICATION
Document Type and Number:
Japanese Patent JP2023173396
Kind Code:
A
Abstract:
To provide a method for suppressing marine acidification that enables safe and stable treatment of carbonate and improves marine environment.SOLUTION: A method for suppressing ocean acidification includes: an injection step in which carbonate is introduced into ocean, and a step of determining a location for retention by which the location for retaining carbonate is determined based on ocean acidity, wherein carbonate is retained at the location determined in the step of determining the location for retaining carbonate. According to this invention, when injecting carbonate into ocean, a location for retaining carbonate is determined based on ocean acidity, and carbonate is supplied (transported) to and retained in that location, effectively promoting the alkaline pump effect. This enables safe and stable treatment (dissolution) of carbonate, and neutralization of seawater in areas of high ocean acidity (suppression of ocean acidification), as well as improvement of the ocean environment by increasing the efficiency of carbon dioxide absorption.SELECTED DRAWING: Figure 1
