- •
New methodology to detect the presence of submerged shipwrecks.
- •
Ocean colour satellite imagery reveals recurring linear patterns of high sediment concentration.
- •
These patterns align to tidal currents and may extend up to a few km.
- •
Scour pits around the wrecks trap fine sediments during slack tide.
- •
With increasing current the fine sediments are re-suspended and entrained.
