4.4.1
Residence Times Within the Global Ocean
Given the above export production of Fe and 100m depth for the surface part of a 4000m deep ocean,one only needs an average surface water concerntration to arrive at a residence time.assuming an average of 0.2nmolL-1 leads to a residence time of only 0.09 years,i.e. about 1 month.when assuming 0.7 nmoll-1 as average surface water concentration this would yield 0.32years or about 4 months.the lowest concerntration value of 0.07nmoll-1 value would correspond to only 0.032years residence times,that is only 10 days,in surface waters.these would be ttrue residence times,the partial residence time relative to external aeolian input would be twice as long due to assumed equal input from sediments,and some ten-fold longer relative to river input.
Global deep waters with an average concentration of 1nmoll-1 dissolved Fe and 33x109moly-1 mobilisation input would yield a residence time of ~41 years.assuming an average concentration of exactly 0.76nmoll-1 brings this down to~31 years.by selecting 100% mobilisation of the biogenic Fe export or 66x109moly-1 the lower limit residence time would become ~15years.these global deep water residence times in the range15-41years are far below the deep oceanic water mass circulation times in the range of the order of about 1000 years,implying that the global oceanic residence time concept is not applicable to iron.thus the biogeochemical cycling of Fe within one ocean basn,e.g.the North atlantic,is independent and fully separated from the cycling of Fe in,for example,the North pacific basin. 展开

居住在全球海洋时代
鉴于上述的出口生产铁和100米深的表面有一部分是4000米深的海洋,一个人只需要一个平均表面水concerntration来到停留时间。
假设平均0.2 nmolL-1导致只停留时间0.09年,如下。
大约1个月。
当假设0.7 nmoll-1水浓度与平均表面这将产生0.32年或四个月了。
最低的concerntration值为0.07 nmoll-1价值将会符合时代只有0.032年住宅,这是唯一10天,在表层水域。
这些将会ttrue居留时间,部分停留时间及其相对于外部输入将长了一倍,由于输入假设平等沉积物,一些相对于9倍长河流输入。
全球深水平均浓度为1 nmoll-1溶解铁和33 x109moly-1动员输入产量,将停留时间~ 41岁。
假设一个平均浓度为0.76 nmoll-1到底带来这归因于~ 31年。
通过选择100%的生物铁动员出口或66 x109moly-1停留时间的下限会成为~ 15年。
这些全球性深水居留时间在range15-41years远低于海洋深层水质量循环时间范围内的秩序的大约1000年,这意味着全球海洋居留时间观念并不适用于铁。
因此在生物地球化学循环basn铁的一个海洋,举例说明。
北大西洋,是独立的,完全脱离铁的循环,例如,北太平洋盆地。
