Rapidly acidifying waters pose major threat for Southern Ocean ecosystem

manoa-marine-acidification_cropped

As a result of increasing atmospheric carbon dioxide concentrations, the chemistry of the Southern Ocean is expected to change so fast over the next few decades that tiny creatures at the base of the food web may soon struggle to form their shells. New research by scientists from the University of Hawaiʻi at Mānoa and the University of Alaska, Fairbanks ...

Microbes dominate Earth. They have been discovered wherever anyone has looked for them. Every animal and plant relies on interactions with the microbial world for health. Given that nearly every habitat and organism hosts a diverse constellation of microorganisms—its “microbiome”—understanding that complex system could transform ideas about the natural world and launch innovations in agriculture, energy, health, the environment and ...

Corals worldwide hit by bleaching

The current coral bleaching event began last year in the Pacific Ocean. This reef in American Samoa was healthy in December 2014 (left) but had lost its characteristic colour in February 2015 (right). Image courtesy of XL Catlin Seaview Survey.

From Hawai‘i to Papua New Guinea to the Maldives, coral reefs are bleaching — in so many regions that the US National Oceanographic and Atmospheric Administration (NOAA) officially declared a global bleaching event on 08 October 2015. The event, the third in recorded history, is expected to grow worse in coming months. Warm ocean temperatures, linked to climate change and ...

When the eastern flank of Fogo, a Cape Verde volcano, splashed into the sea some 73,000 years ago, it generated an enormous wave that rose to 170 meters of height before it crashed into a nearby island, geophysicists have discovered. The mega-tsunami, reported on 2 October 2015 in Science Advances, is one of the largest in the geological record. The flanks ...
