WebUpwelled waters are high in nutrients, which cause high levels of production by phytoplankton. These phytoplankton are the base of the food chain, attracting high numbers of consumers. Upwelling in the California Current is influenced by seasonal changes in the intensity of northwesterly winds. Webin regions of strong, persistent upwelling than regions of weak, intermittent upwelling leading to higher larval “wastage” and lower larval supply and settlement where upwelling was strong and persistent. They later proposed that, in regions of strong upwelling, larvae accumulating offshore at the upwelling front can be transported back

WebJul 7, 2024 · What causes upwelling and downwelling? Coastal Upwelling Upwelling and downwelling also occur along coasts, when winds move water towards or away from the coastline. Surface water moving away from land leads to upwelling, while downwelling occurs when surface water moves towards the land. Advertisement What would happen if … WebA coastal downwelling is the opposite of a coastal upwelling. Warm surface water can be blown towards the shore by Ekman transport. This warm water mass pushes cold water down and away from the shore. Another kind of downwelling occurs when there is a buildup of the water in the center of a hurricane or in other low-pressure centers. crystal healing candles
