Abstract(Summary)
Sediment coring is a valuable tool for environmental risk assessment to identify geochemical baselines and as a temporal archive of industrial contamination. In freshwater aquatic sediments, where classic gravity coring had inadequate depth penetration and did not yield sufficient sediment recovery, alternate coring strategies and modifications to the coring device were explored and successfully implemented. The addition of threaded drive rods and a sediment depth control ring to a classic gravity corer improved core penetration and retrieval, which resulted in more effective and efficient sediment sampling for geochemical surveys.
