- Abstract
- Total dissolved content of some trace elements (Cd, Cr, Cu, Mn, Pb, Zn), nutrients
(nitrate, phosphate and silicate), fluorescence, salinity, dissolved oxygen and
temperature were measured on several samples collected during 2 oceanographic surveys
from 2001 to 2003 within the framework of the Italian expedition in Antarctica
on board the R.V. Italica. The mean concentrations measured are consistent with literature
data for seawater at high latitude. The concentration value of some elements,
never detected in high latitude seawater before, were compared with the expected
values for oceanic water: the results are in agreement with literature data. As for
all the oceans, also in the Ross sea the relationship between Cd and phosphate is
evident. Some trace elements like copper, cadmium and zinc may have the double
role of micronutrient and toxicant. The geochemical cycle of some trace elements,
like manganese, is principally controlled by the oxidation-reduction reaction. The
obtained results were discussed taking in account the distribution of such trace elements
as a function of the different water masses present during the austral summer
in the western sector of the Ross Sea. (literal)
