NOAA CRUISE STUDIED OCEAN ACIDIFICATION ON THE WEST COAST

West Coast Ocean Acidification Cruise Blog

In the summer of 2013 NOAA conducted an in-depth ocean acidification investigation along the U.S. West Coast! Sailing from Seattle, WA to Moss Landing, CA, chemists and biologists on board NOAA Ship Fairweather sampled and analyzed water, alga and plankton in an effort to better understand how the marine ecosystem is responding to corrosive effects caused by changing ocean chemistry.

Acidification, which is driven by increases in human-caused fossil fuel burning, is particularly threatening West Coast waters given the region’s unique hydrology and large biological communities. Data from this cruise may help America's fishing industry and state and local officials can plan, prepare and protect its commercially-valuable ecosystems.

NOAA Led Study Shows Walleye Pollock Resilience to Ocean Acidification

NOAA Led Study Shows Walleye Pollock Resilience to Ocean Acidification

Scientists at NOAA’s Alaska Fisheries Science Center recently found that some life history parameters of walleye pollock seem to be only minimally affected by high CO2 waters. Dr. Thomas Hurst and University of Alaska colleagues Elena Fernandez and Dr. Jeremy Mathis conducted multiple experiments in conditions mimicking both present day CO2 levels in high latitude waters and those predicted to occur over the next century (280-2100µatm, pH= 7.4- 8.16).

Can Acid Neutralizers Help Coral Reefs Bounce Back?

NPR

Coral reefs are in trouble worldwide, from a host of threats, including warming ocean temperatures, nutrient runoff and increasing ocean acidity. A noted climate scientist from California has been conducting an experiment on Australia's Great Barrier Reef to see whether antacid could boost coral growth.

Increased Carbon Dioxide Levels Damage Coral Reefs

NPR

Scientists have been worried about coral reefs for years, since realizing that rising temperatures and rising ocean acidity are hard on organisms that build their skeletons from calcium carbonate. Researchers on Australia's Great Barrier Reef are conducting an experiment that demonstrates just how much corals could suffer in the coming decades.

Scientists Seek Sea Urchin's Secret to Surviving Ocean Acidification

Scientists Seek Sea Urchin's Secret to Surviving Ocean Acidification

Science Daily

Stanford scientists have discovered that some purple sea urchins living along the coast of California and Oregon have the surprising ability to rapidly evolve in acidic ocean water -- a capacity that may come in handy as climate change increases ocean acidity. This capacity depends on high levels of genetic variation that allow urchins' healthy growth in water with high carbon dioxide levels.

The study, co-authored by Stephen Palumbi, a senior fellow at the Stanford Woods Institute for the Environment and director of Stanford's Hopkins Marine Station, revealspreviously unknown adaptive variations that could help some marine species survive in future acidified seas.
