Mangrove forests are shrinking due to human activities, yet they’re essential for shoreline protection and carbon sequestration. Ongoing research explores the concept of “floating” mangrove forests.
Some Aussie beaches are being reshaped and coastal dunes are marching inland. We used data from aerial photography, field surveys, laser mapping and drones to study incredible rates of change.
A motorist stops to survey the damage to a washed-out roadway near McKay Section, N.S. on July 23, 2023. A long procession of intense thunderstorms dumped record amounts of rain across a wide swath of Nova Scotia, causing flash flooding, road washouts and power outages.

Over 200 million tonnes of sediment are transported by rivers to the sea each year, the most widespread water contaminant in the country. Its devastating impact on marine life has to be reversed.
A survey of Miami-Dade residents found bipartisan support for protecting Biscayne Bay − though most locals were not aware of the extent of its decline in recent years.
With smartphones as commonplace as towels and sunscreen in the beach bag, why not add coastal data collection to your list of holiday activities this summer? Look for the CoastSnap camera cradles.

Saltwater intrusion is bad for human health, ecosystems, crops and infrastructure. Here’s how seawater can move inland, and why climate change is making this phenomenon more frequent and severe.
Rising seas are pushing coastal ecosystems to the limit of endurance. Now international research reveals a “tipping point” will be reached if we allow more than 2 degrees of global warming.
Different strategies are required to save coastlines.
