HIAOOS has planned a lot of Training activities over the coming years. Training will focus on a series of Use Cases:
Use Case 1: Oceanographic and sea ice data analysis (IOPAN, NPI) These data provide the baseline for all marine research in the Arctic. The data are important input in all the use cases where acoustic signals are exploited for different applications.
Use Case 2: Detection and localization of earthquakes using passive acoustics (UIB) There are no seismological observations in the Arctic Ocean, and passive acoustic data from the moorings and the ice buoy will have information about earthquake events.
Use Case 3: Detection localization of marine mammals and man-made sound using passive acoustics (UBAH) Data on marine mammals are needed in marine biology and fisheries management. Noise from ship traffic, seismic surveys and other human activities are important for assessment of the marine environment.
Use Case 4: Validation of ice-ocean reanalysis using acoustic receptions (NERSC) Acoustic propagation is very sensitive to ocean stratification. By simulating acoustic propagation using ice-ocean model fields as input to the acoustic model, and compare the results to observations, the ocean model can be evaluated.
Use Case 5: Acoustic inversion for temperature estimation (FORTH) In acoustic thermometry, acoustic travel times between source and receiver are used to invert to mean sound speed and converted to temperature. Useful for climate monitoring and assessments.
Use Case 6: Acoustic underwater geo-positioning (NERSC) In this case the acoustic receptions are used to calculate the distance to the transmitting source. By having the distance to 3 or more sources, one can triangulate the position of the receiving platform/float.
