Our acid oceans will dissolve coral reef sands within decades

Carbonate sands on coral reefs will start dissolving within about 30 years, on average, as oceans become more acidic, new research published today in Science shows. Carbonate sands, which accumulate over thousands of years from the breakdown of coral and other reef organisms, are the building material for the frameworks of coral reefs and shallow reef environments like lagoons, reef flats and coral sand cays. But these sands are sensitive to the chemical make-up of sea water. As oceans absorb carbon dioxide, they acidify – and at a certain point, carbonate sands simply start to dissolve. The world’s oceans have absorbed around one-third of human-emitted carbon dioxide . Carbonate sand is vulnerable For a coral reef to grow or be maintained, the rate of carbonate production (plus any external sediment supply) must be greater than the loss through physical, chemical and biological erosion, transport and dissolution. It is well known...

Looking for sponsors

I'm looking for a #scubagear #sponsor for various projects we are starting here in #Curacao. Since end of 2017 I have been looking at various ways to be of benefit to the Island of Curacao. Since a few weeks the plans to move forward with both the OC3AN CLUB and the GOBLU3 Initiative have been instigated.

What is ocean etiquette?

Photo: Claire Fackler/NOAA Knowing how to interact with ocean wildlife can help you make the right decisions when you encounter wildlife. Without paying attention to how you interact in the marine environment, you are running the chance of putting endangered species, federally protected species and thousands of other species' lives at risk. Each time someone visits the marine environment, they have the wonderful opportunity to encounter wildlife. However, the unfortunate potential to harm our marine life and resources exists with every visit. Because we love our marine resources and want you to appreciate them, the National Marine Sanctuary System sees every visitor as a potential steward of our sanctuary resources. The Ocean Etiquette program calls on each of you to take on that responsibility. We have listed below a set of general marine wildlife viewing guidelines....

About IYOR

The Third International Year of the Reef At the 31st General Meeting (November 2016 in Paris, France), the International Coral Reef Initiative declared 2018 as the third International Year of the Reef (view the recommendation in French , English , Spanish ) and encourages to: Strengthen awareness globally about the value of, and threats to, coral reefs and associated ecosystems; Promote partnerships between governments, the private sector, academia and civil society on the management of coral reefs; Identify and implement effective management strategies for conservation, increased resiliency and sustainable use of these ecosystems and promoting best practices; and Share information on best practices in relation to sustainable coral reef management. ICRI encourages its members to support and participate in planning for IYOR 2018, and to facilitate the development of national level IYOR activities. For more information, contact the ICRI Secretariat . History 1997 was declared the first International Year of the...
