| Zusammenfassung |
| Microstructure measurements were collected using an autonomous freely rising
profiler under a variety of different atmospheric forcing and sea states in
the open ocean. Here, profiles of turbulent kinetic energy dissipation rate,
ε, are compared with various proposed scalings. In the oceanic
boundary layer, the depth dependence of ε was found to be largely
consistent with that expected for a shear-driven wall layer. This is in
contrast with many recent studies which suggest higher rates of turbulent
kinetic energy dissipation in the near surface of the ocean. However, some
dissipation profiles appeared to scale with the sum of the wind and swell
generated Stokes shear with this scaling extending beyond the mixed layer
depth. Integrating ε in the mixed layer yielded results that 1%
of the wind power referenced to 10 m is being dissipated here. |
