Abstract
In nearly a dozen open- ocean fertilization
experiments conducted by more than 100
researchers from nearly 20 countries, adding
iron at the sea surface has led to distinct
increases in photosynthesis rates and biomass.
These experiments confirmed the
hypothesis proposed by the late John Martin
[Martin, 1990] that dissolved iron concentration
is a key variable that controls phytoplankton
processes in ocean surface waters.
However, the measurement of dissolved iron
concentration in seawater remains a difficult
task [Bruland and Rue, 2001] with significant
interlaboratory differences apparent at times.
The availability of a seawater reference solution
with well- known dissolved iron (Fe)
concentrations similar to open- ocean values,
which could be used for the calibration of
equipment or other tasks, would greatly alleviate
these problems [National Research
Council (NRC), 2002].
The Sampling and Analysis of Fe (SAFe)
cruise was staged from Honolulu, Hawaii, to
San Diego, Calif., between 15 October and
8 November 2004 to collect data and samples
that were later used to provide this reference
material. Here we provide a brief report on the
cruise results, which have produced a tenfold
improvement in the variability of iron measurements,
and announce the availability of the
SAFe dissolved Fe in seawater standards.
