LAKE MOVEMENTS WITH PARTIAL ICE COVER
A recording current meter was operated under a winter ice sheet at Nanticoke, Lake Erie, in 11 m of water at a depth of 3 m from the bottom. Current magnitude and direc-tion and water temperature were measured every 10 min. Current magnitudes up to 1 month after the ice sheet formed were similar to...

Summary: | A recording current meter was operated under a winter ice sheet at Nanticoke, Lake Erie, in 11 m of water at a depth of 3 m from the bottom. Current magnitude and direc-tion and water temperature were measured every 10 min. Current magnitudes up to 1 month after the ice sheet formed were similar to measurements made without ice; auto-variance density spectra for this period showed energy concentrations at frequencies cor-responding to the fret oscillation modes of Lake Erie. Several months after the ice had been in place the measured currents were half as fast (3-9 cm/set) and spectra during this period showed no energy concentrations at Lake Erie oscillation frequencies. |
