Eutrophication.

Explanation: eutrophication is the natural (and often accelerated by human activity) enrichment of water bodies with nutrients, leading to increased productivity and often algal blooms. Oligotrophy is nutrient-poor, upwelling is a coastal/ocean process, and red tides are harmful algal blooms that can result from eutrophication.
