In 2007, kelp forests were also discovered in tropical waters near Ecuador.. Physically formed by brown macroalgae, kelp forests provide a unique habitat for marine organisms and are a source for understanding many ecological processes. Travel. “In December of 2015 the temperatures along here were about 14.5 degrees [Celsius]. As Darwin noted ‘if in any country a forest was destroyed, I do not believe nearly so many species of animals would perish as would here, from the destruction of the kelp’. The warmer currents that have moved south from New South Wales have also caused long-spined sea urchin populations to explode on Tasmania’s east coast. A large wind system, known as a “gyre” spins above the Pacific Ocean, influencing the East Australian Current (EAC) beneath it, which tracks south along the edge of the continental shelf.

The primary culprit is climate change: These giant algae need to be bathed in cool, nutrient-rich currents to thrive, yet regional warming in recent decades has extended the waters of the warmer East Australian Current into Tasmanian seas to devastating effect, wiping out kelp forests one by one. “What we’re seeing is these really interesting changes that confirm our suspicions about how warming is going to completely transform temperate reef systems into something more like a coral reef,” Dr Ling says.
