movements. Found in both saltwater and freshwater environments, these sharks are highly versatile, able to thrive in rivers, estuaries, and coastal seas.For decades, the scientific community has been diligently scrutinized the warming oceans and the consequential impacts on marine biodiversity. While much attention has rightfully been focused on the warming of our seas and the subsequent impacts on marine life, there’s a chillier reality that often escapes the spotlight: extreme cold events.
The Agulhas Current, a swift, warm ocean current off the southeastern coast of Africa, is known for its role in shaping regional climate and biodiversity. However, the recent study has brought to attention a lesser-known phenomenon associated with this current: intense cold upwelling events. These events, characterized by the sudden upsurge of cold, nutrient-rich waters from the ocean depths, lay bare the destructive power of plummeting temperatures in oceanic environments.
What’s alarming is not just the occurrence of these sort of events, but their increasing frequency and intensification. The East Australian Current, renowned for its role in the Great Barrier Reef ecosystem, has also witnessed a surge in upwelling intensity and frequency. As these currents undergo changes due to climate variability, their impact on marine life becomes increasingly pronounced.
