✦ Synopsis

The zinc and lead concentrations were compared in several pairs of sediment cores obtained with a modified K-B corer and by Scuba diver from Coon Lake, Canada . A slow approach to and penetration of the sediments (ca . 0 .1 m s-1 ) was employed for both coring devices . The modified K-B corer gave similar lead and zinc profiles to the diver cores . The divers observed that the K-B corer caused no disturbance of the surface sediment layers as it approached and entered the sediments . These results suggest that the K-B corer is suitable for use in lake studies requiring short, undisturbed cores from fine-grained sediments .
