Description:
The first open ocean deployment of the Skin Depth Experimental
Profiler (SkinDeEP) was from the R/V Melville in the Gulf of California during
the Marine Optical Characterization Experiment (MOCE–5). SkinDeEP is
an autonomous, vertical profiler for the upper few meters of the ocean. During
MOCE–5, SkinDeEP was deployed on 10 separate occasions, and profiles were
made at intervals of approximately one minute each. A total of 976 profiles were
acquired during the cruise. The ocean skin temperatures were measured by the
Marine Atmosphere Emitted Radiance Interferometer (M–AERI), an infrared spectroradiometer.
Typical meteorological conditions were of low winds and high
insolation. The dataset provided captures the near-surface temperature structure
that decouples the skin layer from the conventional in–situ bulk sea surface temperature
measurements made at a depth of a few meters. Data from SkinDeEP
showed strong diurnal warming within the upper few meters, with one extreme
case of 4.6 K. There were large discrepancies when computing the skin–bulk
temperature difference with bulk temperatures at different depths. Results also
show the strong dependency of estimating air–sea heat flux based on SST, with
warm–layer errors of almost 60 Wm-2 associated with intense stratification. This
indicates the importance of the inclusion of the skin temperature for accurate
calculation of latent, sensible, and net longwave heat fluxes.
Description:
The development of SkinDeEP was funded
through the Research Council of Norway (Prosjektnr. 127872/720). Support was provided by the
European Commission under the Marie Curie Fellowship contract ERBFMBICT983162. Further
supportwas provided by NSF grant OCE–0241834 and National Oceanographic Partnership
Program Award No. NNG04GM56G.
