It was possible to study the behavior of germanium species, arsenic species, tin, barium and DMS under N O 3- and Si- limited conditions, as phosphorus (mainly from the Peace River phosphate industry) was not limiting. Measurements were made along the salinity gradient and an estuarine reaction/mix- ing model was applied. Not only were N O 3 and Si consumed by the river mouth diatom bloom, but inorganic germanium was completely incorporated into biogenic opal.

A glass plate sampler was developed to collect the upper 30 to 55 t~m of the sea surface. Pb, Zn, Cu, Cd and Fe concentrations in both the microlayer and bulk water were generally 2 to 15 times greater in the urban than in the rural bay; microtayer concen- trations averaged 6 to 65 times those in the bulk water. Measured microlayer concentrations agree well with those predicted from atmospheric depo- sition rates using a previously derived empirical model. Battelle Mar. Res. Lab., Sequim, WA 98382, USA.

high energy beach [Queen Charlotte Islands, Canada]. Mar. Pollut. Bull., 16(5):191-196,

Oil moved through the beach sediments in response to the tidal cycle and the subsequent changing water table levels. During a flood tide the oil was driven through the sediments to the upper beach face; on the ebb, however, concentrations increased nearly five times as oil was released from the lowering water table onto the surface of the beach face. At low tide some residual oil remained trapped in the sediments. In spite of high wave exposure, traces of fuel remained within 300 m of the spill site after 60 days, suggesting that light, unweathered oil is not me- chanically abraded and dispersed in the same manner as more weathered oil; light oil is released principally during an ebbing tide, and wave action probably affects the cleaning of the beach.

Methyl mercury content increases by three orders of magnitude going from sediment to fish; distributions of methyl mercury in relation to sediment depth and to the different organs of the mussel are presented. Results suggest that non-migratory species of fish are more suitable for methyl mercury monitoring m the marine environment than are sediment and mussels. Centre for Mar. Res.
