Thanks to the interaction of ocean currents with the Patagonia Shoal, the marine ecosystem is truly unique. Branching off the strong Circumpolar Current of the Southern Atlantic Ocean, the fresh pristine Malvinas Current flows north and east along the Argentine coast. It is off this coastline, that the Malvinas converges with warmer southward currents.
According to NASA satellite imagery, the waters are visibly enriched by phytoplankton, iron, and other nutrients from Antarctica and Patagonia. The phytoplankton thrive because of the relatively shallow water of the shoal and the intersecting ocean currents. This convergence of the continental shelf, sunlight, water temperature, salinity, and nutrients attracts aquatic life unique to this area of the world.

Sunlight powers the phytoplankton, which are often referred to as the grass of the sea. Abundant plankton attracts plankton-eating species, along with the fish that eat them. Predator species such as squid and rays abound in the Patagonia Shoal. Ultimately, the Omega-3 content of the entire ecosystem is affected by the impressive phytoplankton concentration.
This results in the altered nutrient profile of the Near-Surface Omegas™.
- ShoalFoods™ are naturally higher in brain-healthy DHA Omega-3*
- Typically deep marine Omega sources can be harvested in the more shallow Argentine waters, with no harm to deep ocean biomes
You can feel good about this Omega-3—in every way!
