Abstract
Official abstract text for this publication.
The present invention is a method of preventing settlement of a sessile organism on a structure in water, including irradiating light comprising the spectrum of 409 to 412 nm to the structure where settlement of the sessile organism is prevented.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of preventing settlement of a sessile organism on a structure in water, comprising the step of irradiating the structure with light consisting of a part of a spectrum of 400 to 440 nm, wherein the light irradiating the structure has a peak wavelength in a range between 409 nm and 412 nm. 2. The method according to claim 1 , wherein the sessile organism comprises an alga, a mussel, a wing oyster, a moss animal, a feather duster worm, a gammaridean amphipod, a sponge, a sea squirt, and a hydroid. 3. The method according to claim 2 , wherein the light is not a laser beam. 4. The method according to claim 1 , wherein the light has a spectral irradiance of 1.4 μWcm −2 nm −1 or higher between 409 nm and 412 nm at the structure. 5. The method according to claim 4 , wherein the light is not a laser beam. 6. The method according to claim 1 , wherein the part of the spectrum consists of a part of a spectrum of 400 nm to 420 nm. 7. The method according to claim 6 , wherein the light is not a laser beam. 8. The method according to claim 1 , wherein an irradiance of the light is 3 Wm −2 or higher. 9. The method according to claim 8 , wherein the light is not a laser beam. 10. The method according to claim 1 , wherein the light is not a laser beam. 11. The method according to claim 1 , wherein the light is LED light. 12. The method according to claim 11 , wherein the light is not a laser beam. 13. The method according to claim 1 , wherein the water is seawater. 14. The method according to claim 13 , wherein the light is not a laser beam. 15. The method according to claim 1 , wherein the part of the spectrum consists of a spectrum of 400 nm to 420 nm.
