Global 3‐D Electrical Conductivity Model of the World Ocean and Marine Sediments

This study presents global 3-D electrical conductivity models of the world ocean and marine sediments. Electrical was calculated by invoking Equation State Seawater (TEOS-10) with temperature salinity data retrieved from World Ocean Atlas a series high-resolution regional climatology sets. The resolution atlas varies between 0. globally. sediments estimated using compaction thermal gradient constrained real observations on 5-arc-minute sediment thickness grid. I present numerical simulations electromagnetic (EM) induction responses that demonstrate significant effect EM for broad range frequencies. show both land-based surveys designed subsurface imaging or Space Weather modeling will benefit inclusion more realistic seabed
