Research objectives and content
Both components of this proposal, experimental and modelling, have been developed for my PhD. A fully working instrument which can be deployed in inner waters has been proven, as well as the feasibility of using a basic artificial neural network to model the bulk - skin temperature difference. Further work in these areas are required to lead to a better understanding of the complex processes that occur at the sea surface. This proposal outlines a study of the sea surface microlayer using thermometric and radiometric techniques to determine sea surface temperature. Profiling of this region of the sea is rarely undertaken due to the lack of instrumentation available whereas remote, infra-red devices are deployed on an operational basis by researchers involved in this area of study. A comparison of the two methods of measuring sea surface temperature would provide a greater understanding of the processes affecting the behaviour of the microlayer. The data from cruises on board NERSC's research vessel as well as from other sources (e.g. CASOTS data-base) would be assimilated into a neural network model towards an improvement in the parameterization of the skin-bulk temperature difference which would prove to be invaluable when interpreting bulk sea temperatures from satellite-derived SSTs. Training content (objective, benefit and expected impact)
Utilisation of NERSC's facilities and expertise will be made which include extensive computing power, infrastructure for instrumentation development, the availability of ship time, and the experienced staff of scientists not available in Ireland. The results would be applicable to other EC-funded projects involved in air-sea interaction including ASGAMAGE, CASOTS, COASTWATCH '95, etc. The possibility of collaboration with other institutes on research cruises also exists.

Although no links at present exist with industry, the technology developed with this profiler could have a commercial possibility, as yet to be explored.
