WebFeb 14, 2024 · • Coastal upwelling occurs where wind blowing along a coastline is influenced by Ekman current moving surface waters offshore, or winds blowing off the land pull surface waters away from the coast, pulling deeper water up to replace surface waters. See Figure 9.18 for locations where coastal upwelling most commonly occurs. WebOct 16, 2024 · Frequent upwelling of deep, cold water, rich in dissolved inorganic nutrients and carbon dioxide but low in oxygen concentrations and pH, is well documented in eastern boundary systems. As a consequence, waters in vast areas of the continental shelf can turn corrosive to the mineral aragonite, vital to a number of marine organisms. This …
WebHuman Impacts on Marine Species Students learn about three examples of human impacts on marine life: migration patterns and shipping, algal blooms and water chemistry, and marine debris. Some of these impacts are due to human activity in the ocean, and some impacts on the ocean are due to human activity on land.

WebThe upwelling of cold, nutrient rich waters from around 200–300 m depth results in high rates of phytoplankton growth that sustains the Benguela ecosystem. The intensity of upwelling events is determined by wind strength. Variations in wind strength cause pulses of upwelling, which propagate to the south along the coast with speeds of 5 to 8 m/s.
