Hypoiodous Acid Triggers Ozone Destruction Over Oceans

Scientists have established that the majority of ozone-depleting iodine oxide observed over the remote ocean comes from a previously unknown marine source - the principal source of iodine oxide can be explained by emissions of hypoiodous acid (HOI), a gas not yet considered as being released from the ocean, along with a contribution from molecular iodine (I2). Since the 1970s when methyl iodide (CH3I) was discovered as ubiquitous in the ocean, the presence of iodine in the atmosphere has been understood to arise mainly from emissions of organic compounds from phytoplankton -- microscopic marine plants. read more
