Ocean acidification is sometimes called “climate change’s equally evil twin,” and for good reason: it's a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don't see or feel because its effects are happening underwater.

Sentinels of ocean acidification impacts survived Earth's last mass extinction Date: September 28, 2020 Source: University of Hawaii at Manoa Summary: The loss of coral reefs impacts local economies, affects the health of fisheries and tourism, and exposes coastal communities to increased storm surge. As their shells are susceptible to dissolving in more acidified ocean water, pteropods have been called "canaries in the coal mine," or sentinel species that signal the impact of ocean acidification. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2'); }); Sea butterflies and sea angels are pteropods, abundant, floating snails that spend their entire lives in the open ocean. endstream endobj startxref Hawaiian ‘supercorals’ that can tolerate warm, acidic waters offer hope for the future Published 17 May 2019 Press ... and calcareous plankton, are dramatically affected by ocean acidification. Two groups of tiny, delicate marine organisms, sea butterflies and sea angels, were found to be surprisingly resilient—having survived dramatic global climate change and Earth's most recent mass extinction event 66 million years ago, according to research published this week in the Proceedings of the National Academy of Sciences led by Katja Peijnenburg from Naturalis Biodiversity Center in the Netherlands. It is still an open question whether marine organisms, particularly those that calcify, have the evolutionary resilience to adapt fast enough to an increasingly acidified ocean.

This is known as ocean acidification, which can threaten the ability of shellfish and corals to build their skeletons, hamper new coral growth and accelerate reef erosion. Thank you for taking your time to send in your valued opinion to Science X editors. One example is that Hawaiian tradition considers corals to be source of all life, and damage to reefs could result in loss of sense of place for Native Hawaiians. The buoy will measure carbon dioxide and other important seawater characteristics within the bay’s vibrant tropical coral reef ecosystem.

In addition to work on ocean acidification, students and staff conduct observational, experimental, and theoretical studies that cover a broad spectrum of research in the areas of marine chemistry and global biogeochemical cycles.

"Although these results suggest that open ocean, shelled organisms have been more resilient to past ocean acidification than currently thought, it is unlikely that pteropods have experienced global change of the current magnitude and speed during their entire evolutionary history," said Erica Goetze, co-author and University of Hawai'i at Mānoa oceanographer. Ocean acidification is affecting the entire world’s oceans, including coastal estuaries and waterways.
