Previous studies have indicated that burrow-irrigating infauna can increase sediment oxygen demand (SOD) and impact hypolimnetic oxygen in stratified lakes. We conducted laboratory microcosm experiments and computer simulations with larvae of the bur

Faunal surveys of western Lake Erie showed a dramatic change in the species composition and abundance of the invertebrate mud-bottom community. Abundances of formerly dominant ostracods, tubificid and naidid oligochaetes, and chironomids declined 85%

Previous studies support the hypothesis that large numbers of infaunal burrow-irrigating organisms in the western basin of Lake Erie may increase significantly the sediment oxygen demand, thus enhancing the rate of hypolimnetic oxygen depletion. We c

Vertical profiles of the activities of 137Cs and 210Pb were measured on floodplain sediment cores and upland soil cores along the Soda Butte Creek and the Yellowstone River to determine floodplain sedimentation rates. The position of mine tailings fr

A laboratory experiment was conducted to determine the effect of tubificid worms on the flux of zinc into lake sediments. Forty-six cores of Lake Erie sediment, with and without (control) tubificid worm populations, were exposed to aquarium water wit

Infauna at six stations in western Lake Erie was sampled on four occasions during 1981–1982 to determine if natural patterns of distribution and abundance reflected the response to disturbance that was revealed previously in tray colonization exper

Open space (defaunated sediment) was provided on the floor of Lake Erie on 11 occasions during different seasons over a 26-mo period. The benthic community that developed was sampled over time and compared with the nearby undisturbed bottom community

Video sediment‐profile images and cores were collected from a site 300 m deep in southeastern Lake Superior (47° 12.03'N, 86° 04.80'W) using a submersible. These observations revealed additional large linear trenches in bottom sediments made by t

The activity of fallout radionuclides ( 7 Be, 1 3 7 Cs, and 2 1 0 Pb) was measured on upland and floodplain soils and on suspended sediments to quantify sources of fine sediment and to estimate sediment transport distances in stream channels in the Y

The thermodynamic tendency of metal phosphate and carbonate mineral phases to precipitate in Lake Erie sediments has been calculated by means of an ion-pair model of the interstitial water chemistry. The calculations suggest that detrital calcite, ar
