RS-Freetext:
Gulf of Mexico surface maxima 1-2 x 10E-7 M (3.4-6.8 µg/l).
Samples: May and August 1982 in a variety of locations
ranging from oligotrophic oceanic stations to highly
productive coastal sites. Depth profiles of hydrogen
peroxide exhibit surface maxima of 1-2 x 10E-7 mol/L and
decreasing conc. with depth. Hydrogen peroxide
concentrations decreased only slightly or were invariant
with depth in the mixed layer but decreased sharply to below
the limit of detection (5 x 10E-9 mol/L) at the base of
mixed
layer. Diel variations were more pronounced in coastal
surface waters than in oligotrophic waters.
