Strengthening the net: Ocean acidification observations in California

Strengthening the net: Ocean acidification observations in California

NOAA Ocean Acidification Program

A foggy morning on the central California coastline is a picturesque scene of rolling waves, screeching gulls, and fishermen hauling hefty nets teeming with fish. If you look closely at the net you observe that it is a framework of lines working together to capture a greater amount of fish than a single fishing line could capture alone. In the same way, ocean observing systems can be thought of as a net to capture what is happening with our ocean’s chemistry. But a net with gaps or holes is not very efficient, whether it be in fishing or in observing. A newly funded project by Dr. Chris Edwards, a Professor at the University of California Santa Cruz (UCSC), along with collaborators at UCSC and the Monterey Bay Aquarium Research Institute (MBARI) is taking a look at where ‘holes’ in our observing system are. The team will identify ways to fill those gaps in order to capture changing ocean chemistry along the California coast.

Optimizing Acidification Observations In A Changing Ocean

Optimizing Acidification Observations In A Changing Ocean

NOAA Ocean Acidification Program

There are hundreds if not thousands of eyes on our changing ocean at any moment: Buoys, gliders, saildrones and ships measure carbonate chemistry and new ocean observing technologies are continually being created to monitor ocean acidification. As science and technology progress it is important to ensure that the most up to date knowledge is applied to the task at hand. NOAA’s Ocean Acidification Program (OAP) is teaming up with the U.S. Integrated Ocean Observing System (IOOS®) to fund four projects aimed at improving the observing system design for characterizing ocean acidification. This work will evaluate the capability of existing observations to characterize the magnitude and extent of acidification and explore alternative regional ocean acidification observing approaches. Ultimately this work will minimize errors in measurements, better integrate existing observations, and minimize costs of monitoring ocean acidification.

New NOAA, partner buoy in American Samoa opens window into a changing ocean

New NOAA, partner buoy in American Samoa opens window into a changing ocean

NOAA Research

NOAA and partners have launched a new buoy in Fagatele Bay within NOAA’s National Marine Sanctuary of American Samoa to measure the amount of carbon dioxide in the waters around a vibrant tropical coral reef ecosystem.

“This new monitoring effort in a remote area of the Pacific Ocean will not only advance our understanding of changing ocean chemistry in this valuable and vibrant coral ecosystem but will also help us communicate these changes to diverse stakeholders in the Pacific Islands and across the United States,” said Derek Manzello, coral ecologist with NOAA’s Atlantic Oceanographic and Meteorological Laboratory.

$3.5 Million Awarded to Identify Acidification Thresholds in Coastal Ecosystems

$3.5 Million Awarded to Identify Acidification Thresholds in Coastal Ecosystems

NOAA Ocean Acidification Program

NOAA National Centers for Coastal Ocean Science (NCCOS) and Ocean Acidification Program (OAP) have jointly funded four projects totaling $3.5 million to identify the threshold at which ecosystems change rapidly and their services are irreversibly altered. From the Chesapeake Bay to the coastal waters of Alaska, this work will help managers reduce stressors to avoid the decline or potential collapse of valuable marine ecosystems.

Piecing together the ocean acidification puzzle along the US West Coast

Piecing together the ocean acidification puzzle along the US West Coast

NOAA Ocean Acidification Program

Emma Hodgson, a Liber Ero Postdoctoral Fellow at Simon Fraser University, and her colleagues are making big strides in piecing together the ocean acidification puzzle along the US west coast for those that make decisions around this ocean change. As part of her doctoral research at the University of Washington, Hodgson worked with a team to design modeling tools that create a better picture of ocean acidification impacts on fisheries catches, economies, and communities in this US region.
