Sea Change: Vital part of food web dissolving

Sea Change: Vital part of food web dissolving

The Seattle Times

It didn’t take long for researchers examining the tiny sea snails to see something amiss.

The surface of some of their thin outer shells looked as if they had been etched by a solvent. Others were deeply pitted and pocked.

These translucent sea butterflies known as pteropods, which provide food for salmon, herring and other fish, hadn’t been burned in some horrific lab accident.

They were being eaten away by the Pacific Ocean.

For the first time, scientists have documented that souring seas caused by carbon-dioxide emissions are dissolving pteropods in the wild right now along the U.S. West Coast. That is damaging a potentially important link in the marine food web far sooner than expected.

NOAA-led researchers discover ocean acidity is dissolving shells of tiny snails off the U.S. West Coast

A NOAA-led research team has found the first evidence that acidity of continental shelf waters off the West Coast is dissolving the shells of tiny free-swimming marine snails, called pteropods, which provide food for pink salmon, mackerel and herring, according to a new paper published in Proceedings of the Royal Society B.

Scientists warn ocean food supply may be impacted by rising CO2

Scientists warn ocean food supply may be impacted by rising CO2

NBC News

Marine biologists are searching for evidence of what our oceans will look like if carbon dioxide levels continue to increase. Thirty percent of the carbon dioxide, or CO2, released into the atmosphere is absorbed by the ocean, leading to a process called acidification. Shellfish and coral reefs are particularly impacted, according to Jason Hall-Spencer of Plymouth University. “We’ve never put this much carbon dioxide into the ocean before,” he said. “It’s never happened before in Earth’s history. Not this quickly.” NBC’s Ann Curry reports.
