2026, How to Fish Upwelling Around Offshore Structure
When current hits offshore structure, cold nutrient-rich water rises toward the surface. That localized upwelling compresses bait and predators into defined zones. This article breaks down which structures create the strongest upwelling, how to read the signs before and during a trip, and how to position and present baits where predators actually feed.

2023, Ocean Upwelling and Altimetry Maps for Offshore Fishing
Altimetry maps and ocean upwelling data cut through the guesswork of offshore fishing. Understanding sea surface height anomalies, current fronts, and upwelling zones puts you on tuna, marlin, and other pelagic fish faster and more consistently. This is the science behind where the fish are, and how the best offshore captains locate them before they ever leave the dock.
