    I avoid swimming pools - too noisy!
    (And I'm not much of a swimmer - it's basically slow drowning!!)

    As recreational diver I know a bit about bouyancy and depth only makes a difference when the weight of the water compresses the airspace in a wetsuit or bouyancy jacket so that is displaces less water and is therefore less bouyant. Seawater provides more buoyancy because of the salt dissolved in it. It is therefore more dense and will support more weight for the volume of water displaced.

    I thought there may be some turbulence effect in shallow water causing
    drag. FINA specifies a minimum depth for official pools of just 1 metre
    which would imply no such effect. However the Olympics specify a
    minimum depth of 2 metres (why?). Perhaps a physicist could help?
