海带在温带沿海地区的海洋和大气碘循环中起着重要作用，对沿海海洋边界层的臭氧破坏具有潜在的广泛影响。然而，人们对海带森林对沿海海水中碘物种形成的影响知之甚少。为了解决这个问题，我们检查了美国加利福尼亚州圣地亚哥附近一个巨大的海带森林及其周围海水中的碘化物和碘酸盐浓度，以及附近一个不受海带生物学影响的地点。我们的数据表明，虽然附近站点的碘化物和碘酸盐浓度在一年中保持不变，但这些浓度在海带森林内部和周围发生了显著变化，并且与海带冠层生物量的变化密切相关。特别是在夏季，当海带冠层接近最大值时，碘化物浓度最高，碘酸盐浓度最低，而在冬季和春季，当海带冠层接近最小值时，则相反。此外，这些变化与相应的海水温度和风速变化的比较表明，这些关系与海带生物量的变化相比相对较小。总之，我们的数据显示了海带生物量和碘代谢之间的密切关系。
Kelps have a major role in marine and atmospheric iodine cycling in the coastal zone of temperate regions, with potential wide-ranging impacts on ozone destruction in the coastal marine boundary layer. However, little is known about the impact of kelp forests on iodine speciation in coastal sea water. To address this, we examined iodide and iodate concentrations in seawater in and around a giant kelp forest near San Diego, CA, USA, and a nearby site that was not influenced by kelp biology. Our data shows that while both iodide and iodate concentrations remained unchanged during the year at the nearby site, these concentrations changed significantly in and around the kelp forest, and were strongly related to changes in kelp canopy biomass. In particular, iodide reached its highest concentration and iodate reached its lowest concentration during the summer when the kelp canopies were near their maximum, while the opposite pattern was observed during the winter and spring when the kelp canopies were near their minimum. Further, comparisons of these changes with corresponding changes in seawater temperature and wind speed indicated that these relationships were relatively small compared to those with changes in kelp biomass. Together, our data show a strong relationship between kelp biomass and iodine metabolism.
