More confirmation of previous research by Dr Kench:
New research says hundreds of islands in the Pacific are growing in land size, even as climate change-related sea level rises threaten the region.
- Coral reef sediment was responsible for the increase in land size
- Waves sweep up the sediment and deposit it on islands
- However some islands are becoming smaller due to coastal erosion
Scientists at the University of Auckland found atolls in the Pacific nations of Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have grown up to 8 per cent in size over the past six decades despite sea level rise.
They say their research could help climate-vulnerable nations adapt to global warming in the future.
The scientists used satellite images of islands as well as on-the-ground analysis to track the changes.
Coastal geomorphologist Dr Paul Kench said coral reef sediment was responsible for building up the islands.
Dr Kench said in areas where coral reefs were healthy, enough sediment was being produced to cause islands to grow.
"The majority of islands in each of those nations has either got larger or stayed very similar in size," he said.
"So, you know, one of the remarkable takeaways of the work is that these islands are actually quite dynamic in a physical sense."
