Marine notes, often referred to as sea water accords, are synthetic olfactory recreations of the fresh and invigorating scent of the ocean. Introduced to perfumery in the late 20th century, marine notes evoke the essence of sea breeze, salty air, and the aquatic freshness of the open water. Commonly used as top or middle notes, they add a crisp and revitalizing character to fresh, aquatic, and aromatic compositions.

Marine notes have a fresh, clean, and salty aroma that captures the essence of ocean air and sea spray. Their scent is airy and crisp, with subtle mineral and ozonic nuances that evoke a sense of coolness and tranquility. Slightly watery and briny undertones add depth, creating a natural and invigorating quality that enhances the freshness of fragrances.
