Abstract

Iodine in sea water samples from the Northeast Pacific and Arctic Oceans was determined by two independent methods of analysis, one of which was also capable of determining iodate. Both oceans showed a constant iodine-chlorinity ratio of 3·3 × 10−6 at depths from 250–4000 metres. Some significant variation was observed in the iodine chlorinity ratio in the surface layers. In the North Pacific from one- to two-thirds of the total iodine was present as iodate, with no discernible trends with depth or location. In the Arctic, the iodate increased with depth — from a minimum near the surface to a maximum at 500–1000 metres-where 100 per cent of the iodine was found to be iodate. More iodate was present in the Arctic from 200–2000 metres than was present in any North Pacific sample.

Inland waters of the State of Washington showed iodine-chlorinity ratios about 15 per cent lower than oceanic stations, probably due to accumulation of iodine by benthonic algae.

海水中总碘和碘酸碘含量
通过两种独立的分析方法测定了东北太平洋和北冰洋海水样品中的碘,其中一种方法也能够测定碘酸盐。在250-4000米的深度,两个海洋的碘氯比恒定为3·3 × 10−6。表层的碘氯比有明显的变化。在北太平洋,碘总量的1 - 2 / 3以碘酸盐的形式存在,在深度和位置上没有明显的趋势。在北极,碘酸盐随着深度的增加而增加——从接近地表的最小值到500-1000米的最大值——在那里发现100%的碘都是碘酸盐。在200-2000米的北极地区,碘酸盐比任何北太平洋地区的样本都要多。华盛顿州内陆水域的碘氯比比海洋监测站低约15%,这可能是由于底栖藻类积累碘所致。
