Abstract
Vertical profiles of pore water and sediment solids chemistry were obtained
from two sites in Lake Erie. Samples were collected using both gravity
coring and pore water "peeper" techniques. In general, concentrations of
nutrients and toxic metals in sediment solids decreased with increasing depth.
Comparison of pore water "peeper data to gravity core data showed that
"peeper" data provides higher resolution near the sediment-water interface.
Modifications of the present peeper are required to adequately sample easily
oxidizable materials (e.g. ammonia, ferrous iron).
