CARBON SEQUESTRATION IN BENTHIC MATS OF SOLAR SALT PONDS

摘要：

A technique has been devised to determine the metabolic production and reduction of oxygen by the benthiccommunity in solar salt ponds. The nett oxygen production can be readily converted to an approximation ofthe carbon sequestration.Three solar salt fields have been surveyed biannually over four years. The ponds with a significant benthicmat were surveyed and typically were in the salinity range of 100 g l-1 to 250 g l-1.The average carbon sequestration was 0.30 tonne of carbon per hectare but this varied between a minimumof -0.3 tonne of carbon per hectare per year to a maximum of 2.2 tonnes of carbon per hectare per year.Seven of the eight ponds tested always recorded a positive carbon sequestration. Various parameters thatmay influence the amount of carbon bound into the benthic mat were investigated.
