During NURC REP10 cruise a number of experiments will be conducted using underwater gliders.

During REP10 two METOC officers will be available. They will be asked to fill a questionnaire each morning and afternoon, concerning forecasts of gliders’ positions and how good would be their recovery in the future in specific positions. They have to answer first with the use of METOC forecasts only, and then together with the help of a decision support system. The goal is to demonstrate whether or not the decision support system biases them towards better predictions or not. A similar scheme will be adopted for testing the usefulness of another decision support tool developed at NURC (called model-based), which predicts future trajectories of gliders (and the associated uncertainties).

Abstract
During NURC REP10 cruise a number of experiments will be conducted using underwater gliders. Planning missions related to gliders is not an easy task, since glider missions (such as way-point planning, gliders deployment, surfacing and recovery) are heavily affected by meteorological and atmospheric (METOC) conditions. From this comes the need for decision support tools. NURC is developing decision support systems for generic maritime operations since 2002 and today a decision support architecture is operational. Provided that it is appropriately configured, it is able to mimic human expertise in judging whether environmental conditions are favourable or not for glider deployment, recovery and surfacing etc. How good and useful such decision support architecture is has to be carefully evaluated. During REP10 two METOC officers will be available. They will be asked to fill a questionnaire each morning and afternoon, concerning forecasts of gliders’ positions and how good would be their recovery in the future in specific positions. They have to answer first with the use of METOC forecasts only, and then together with the help of a decision support system. The goal is to demonstrate whether or not the decision support system biases them towards better predictions or not. A similar scheme will be adopted for testing the usefulness of another decision support tool developed at NURC (called model-based), which predicts future trajectories of gliders (and the associated uncertainties). In case the validation succeeds, it can be used to raise alarms when a glider is expected to exit the assigned working area.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
