mixed fishery a fishery targeted at a mix of species. The demersal trawl fisheries
for roundfish and flatfish provide typical examples. Management of these
fisheries is faced with specific problems, because regulations with respect to
one species have necessarily consequences for the others.
mixed layer water layer in which the vertical mixing is intense enough to give a
homogeneous distribution of temperature and salinity as well as of other
properties over its full depth. The term is mostly applied to the surface layer,
where the air-sea exchange causes strong convection and/or turbulence. It may
be bounded underneath by a pycnocline. Over large parts of the ocean the
mixed layer varies seasonally and diurnally in depth.
mixed tides tides with an alternation of semidiurnal and diurnal tides, occurring in certain sea areas. -7harmonic analysis of tides.

models idealized representations of reality (the prototype). In oceanographic
models the actual processes in the sea are simulated on the basis of underlying physical, chemical, and biological theories. They are used as a tool for further investigations and for predictions. Models are most advanced in physical oceanography but ecological models are more and more used. Models are
formulated in the form of a set of mathematical expressions (mathematical
models) that are either solved analytically, or in numerical models are solved
in a grid and with discrete time steps. Furthermore there are analog models,
