| Abstract: | Resuspension of bottom sediments by waves and tidal currents was investigated in three characteristic environments of middle
Chesapeake Bay (shallow platform, deep platform, and main channel). In the shallow near shore platform wind waves frequently
resuspended significant amounts of sediment, some of which was transported offshore. In both the shallow and adjacent deep
platform regions, tidal currents were too weak (<20 cm cm/sec) to resuspend bottom sediments. In the main channel, peak current
velocities were substantially stronger (40 cm/sec), but were still not competent to erode the bottom. The stability of the
bottom in this area is related to the activities of the benthic organisms which are influenced by seasonal anoxia.
