Which rainforest receives large amounts of mineral dust blown westward from the Sahara?

The story behind the answer

The Amazon rainforest receives large amounts of mineral dust blown westward from the Sahara.

Trade winds carry Saharan dust across the tropical Atlantic Ocean, and some of it settles over the Amazon Basin. The dust contains phosphorus and other minerals that can help replace nutrients lost from heavily weathered tropical soils.

Satellite observations and atmospheric research have shown that the Sahara is a major distant source of phosphorus for Amazon ecosystems. This does not mean every dust plume reaches the forest, since rainfall and winds determine where particles are deposited.

Saharan dust also travels to the Caribbean and can affect air quality there. The Amazon connection is a long-distance nutrient cycle, not a direct land bridge between the two regions.
