Do High SSTs Increase the Risk of Flooding (and Sediment Overload)?
Increased flooding of nutrients and sediments
- Positive Feedback: warming of sea surface temperatures leads to increased ice melting and evaporation and increased humidity creates more intense storms, more extreme precipitation, and wind events. Some areas because of increased evaporation will experience intense surface drying increasing the risk of flooding when intense storms occur.
- Sediment and nutrient loads may occur as chronic long term loads and short term pulses such as river flood plumes, related to storm events. When SSTs rise it can shift the weather patterns and tracks of storms. This can lead some places to experience unusual dry spells and droughts. Increased sea surface temperatures have also been linked to more violent storms when they do occur. The dry soil quickly reaches its capacity and the water runs off into the coral reefs taking with it excess nutrients and sediments. [2]
- Corals thrive in a nutrient poor environment. Excess nutrients from storm water runoff gives algae an advantage and can lead to phase shifts on the coral reefs.
