    Notes: ABSTRACT. Analyses of observations from four lakes in British Columbia, Canada, compare estimates of the amplitude of thermocline deflections to predictions of wind-driven internal seiche amplitudes made using the Wedderburn number, W. The study sites range from the 750 m diameter Brenda Mines pit-lake to the 107 km long Kootenay Lake. Causal filtering of the wind data with a frequency cut-off based on the fundamental baroclinic time-scale is critical for correct calculation of W. With the filtering incorporated, good comparison between W, its integral equivalent the Lake number L N and the observations can be made. In all but the mine pit-lake, upwelling or near-upwelling conditions (W≈1) were encountered.

    Notes: Abstract This paper describes a model of the diffusive boundary-layer around anaquatic macrophyte blade. Nutrient uptake at the base of the modelledboundary-layer was examined using previously published laboratory data. Theanalysis showed that, over the outer velocity range 0.01–0.16ms−1, nutrient uptake varied between that predicted byflat-plate boundary-layer theory and that expected with no mean advection. Aratio of theoretical and actual nutrient uptake rates was defined as a meansof categorising the transition between the two transport models. Themodelling was extended to show how fluctuating boundary conditions mayenhance nutrient uptake by the macrophyte; the scenario examined heresuggested that at otherwise low outer velocities, periodic stripping of theboundary-layer by passing waves increased nutrient uptake by a factor of 10.
