Cyclones can damage even distant reefs

Research finds current models underestimate the impact of hurricanes and typhoons on coral reef communities

Big and strong cyclones can harm coral reefs as far as 1000 kilometres away from their paths, new research shows.

A study led by Dr Marji Puotinen from the Australian Institute of Marine Science (AIMS) sounds a warning about the way strong cyclone winds build extreme seas that affect coral reefs in Australia and around the world.

Conventional modelling used to predict how a cyclone, hurricane or typhoon might impact corals assumes that wave damage occurs primarily within 100 kilometres of its track.

A New Hope for Coral Reefs: Largest-Ever Study Unlocks Global Solution to Save Coral Communities

Scientists urge priority action on hundreds of surviving reefs.

The majority of 2500 reefs surveyed in a major international exercise retain the coral species that give them their distinctive structure.

More than 80 marine scientists, including several from Australia, contributed to the study, which is published in the journal, Nature Ecology and Evolution.

While coral reefs around the world are feeling the heat, little-known reefs in Australia’s Kimberley region are prospering, despite living in some of the toughest conditions—and scientists aren’t yet sure why.

The discovery has particular significance this summer with fears of a severe coral bleaching event to hit our northern waters—the result of steadily rising sea temperatures and a strong seasonal El Niño.

WA researchers have found that while coral reefs all around the world are feeling the heat of rising temperatures, some inshore reefs in the Kimberley region’s Bonaparte Archipelago are prospering, despite living in some of the toughest conditions.
