The main objective of this project is to develop a better understanding of the behavior of diffusive electromagnetic induction (EMI) fields in UW environments by researching EMI forward and inverse models which account for the air-water-seabed environment. This understanding will enable EMI instruments to more effectively operate UW and will enable more accurate interpretation of EMI data acquired UW. Specifically,
- Develop forward and inverse EMI models to accurately account for the underlying physics of EMI fields in UW environments.
- Investigate the behavior of diffusive EMI fields in the air-water-seabed environment.
- Assess and mitigate the effects of conducting media on both the primary and secondary EMI fields.
- Perform a preliminary assessment of the effectiveness of the enhanced models.
