Differential sensitivity of Saccharina latissima (Phaeophyceae) to emissions from corrosion protection systems informs biomonitoring strategies

Corrosion protection systems used on offshore structures release metals or chlorine-produced oxidants into surrounding waters. Yet, their effects on marine biomonitoring species remain poorly understood. Here, we assess how emissions from induced current cathodic protection systems and zinc- and aluminium-based galvanic anodes affect the early developmental stages of the kelp Saccharina latissima. Zoospores and gametophytes were exposed for three weeks to metals or chlorine-produced oxidants at
