| Abstract: |
Subsurface Connections from Shore Fresh water in underground aquifers on land can seep through fissures and porous rock that extend out under the seafloor. The signal varies, with salt water in rock cracks and pores conducting electric current better than fresh water, revealing where fresh water is lurking. Rainfall during Low-Sea-Level Period When sea level was low during ice ages, rain may have fallen on exposed seafloor sediment and filtered down through gaps in the cap rock, into porous rock below. This cap prevents the less dense fresh water from rising up to the seafloor. [Extracted from the article] |
