Alimentos de las profundidades

The document describes a specific oceanographic mechanism on the Patagonian shelf where deep ocean currents force nutrient-rich cold water to the surface. This process, unlike wind-driven upwelling, remains active year-round, sustaining a vast food chain including phytoplankton, hake, and squid, and contributing to the ocean's role as a carbon sink. The influence of this system extends northward, fertilizing waters as far as Brazil.

• Coastal upwelling regions represent only 1% of the total ocean surface but support up to 50% of global fisheries and a significant portion of total ocean production.
• Upwelling on the Patagonian shelf is driven by deep ocean currents and seafloor topography rather than wind, distinguishing it from systems like those off the coasts of California or Oregon.
• Because it is driven by currents, the Patagonian shelf upwelling is active continuously throughout the year, whereas wind-driven systems typically last only days or weeks.
• The nutrient-rich waters from the Patagonian upwelling and the Malvinas Current extend northward, contributing to productive ecosystems along the coasts of Uruguay and southern Brazil.
• The biological production resulting from this upwelling supports a complete trophic chain—including anchovies, hake, and squid—and aids the ocean in sequestering atmospheric carbon dioxide.
