Abstract

The sea fluxes of trace metals

POC

and settled material were studied in anoxic seawater

Saanich Inlet

B. C.

Canada with sediment traps. This paper discusses the change of mass fluxes of sediment

trace metals and POC for various seasons and depths. The annual mean of settled material is 1.56 g.m−2.a−1

84.6 mg. m−2.a−1 for POC

60.0 mg. m−2.a−1 for Cu

16.5 mg.m−2.a−1 for Pb

189 mg.m−2.a−1 for Zn

2.20 mg.m−2.a−1 for Cd

699 mg.m−2.a−1 for Fe

38.8 mg.m−2.a−1 for Co

and 84.6 mg.m−2.a−1 for Ni. The relations between the average fluxes of trace metals and POC

the fluxes of trace metals and settled matter

and the sea fluxes of trace metals and Fe are in linear progression. The resident times of elements as calculated from sea flux

are 1.1 a. for Cu

0.014 a. for Pb

0.50 a. for Zn

3.8 a. for Cd

0.16 a. for Fe

0.39 a. for Co

and 1.14 a. for Ni. The order of resident times is as follows: Pb−Fe−Co−Zn−Cu−Ni−Cd. The metal resident times in Saanich Inlet are shorter than the values estimated for the open ocean. It illustrates that the biochemical processes in shallow Saanich Inlet are faster than those in the open ocean

and that debries of plankton and fecal pellets of zooplankton play an important role in vertical transport of organic carbons.
