Nutrient enrichment and depletion on the shoreside of the spring thermal front

摘要: Abstract A thermal front was evident within the nearshore zone of south shore Lake Ontario near Oak Orchard Creek on 28 May 2008. Here, we characterize nutrient concentrations during bar formation shoreside and lakeside a 5 × 20-km polygon. We observed that total phosphorus levels turbidity were elevated while silica nitrate reduced relative to offshore front. Phosphorus suspended solid flux from contributed not transported Two hypotheses, mutually exclusive, are offered as potential explanations for reduction in nitrate: biological uptake by phytoplankton benthic algae long-shore transport poor Niagara River water. This work only demonstrates entrapment may occur but also mechanisms function reduce
