説明

<jats:p>Hydrogen peroxide concentrations have been determined in marine rain from the Gulf of Mexico <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/jgrc3881-math-0001.gif" xlink:title="math image"/>, the western Atlantic Ocean <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/jgrc3881-math-0002.gif" xlink:title="math image"/>, and one rain event off the Florida Keys <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/jgrc3881-math-0003.gif" xlink:title="urn:x-wiley:01480227:media:jgrc3881:jgrc3881-math-0003"/>. In several cases, simultaneous measurements of the concentration of H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub> in the surface ocean were also determined. These measurements were made with the ship under way using a continuous flow sampling system with the intake at the bow. In shallow stratified layers, rain events can increase the existing hydrogen peroxide concentration by a factor greater than 10 and dramatically increase the mean H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub> concentration of mixed depth layers of 50 m or more. Rain is a significant transient source of H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub> in the surface ocean.</jats:p>
