              modelling has been growing steadily in the last few years. One
              advanta ge of using unstructured meshes is that one can
              concentrate resolution where it is needed. In addition, dynamic
              adaptive mesh optimisation (DAM O) strategies allow resolution to
              be concentrated when this is required. Despite the advantage that
              DAMO gives in terms of improving the spatia l resolution where
              and when required, small-scale turbulence in the oceans still
              requires parameterisation. A two-equation, generic length scal e
              (GLS) turbulence model (one equation for turbulent kinetic energy
              and another for a generic turbulence length-scale quantity) adds
              this param eterisation and can be used in conjunction with
              adaptive mesh techniques. In this paper, an implementation of the

              both a laboratory-scale experiment and real-world observations,

              matching labora tory and observed data, with resolution being
              adjusted as necessary by DAMO. Flexibility in the prognostic
              fields used to construct the error m etric used in DAMO is
              required to ensure best performance. Moreover, the adaptive mesh
