AB: Physical Limnology has matured to the point where a fairly complete inventory of processes and their dynamical description is now available. To illustrate this, I will present a brief summary of the processes underlying the response of the water column to a sudden wind event and show how this may be quantified using the Wedderburn and Burger numbers. These knowledge is making it possible to provide the biogeochemist with a quantitative description of the transport and mixing of their state variables. New advances in field instrumentation has allowed real time self learning modelling of both the physics and the biogeochemistry. Currently we are adding real time DNA analysis opening up the possibility of measuring in-situ growth rates at the species level. Together these tools are allowing the prediction of both the population parameters of the state variables and for times out to the autocorrelation times, the state variable itself. After describing this, I will conclude with a brief look at the new challenge in environmental management of lakes and other domains; the inability of humans to make the right decisions.
