Carbon capture and ocean acidification mitigation potential by seaweed farms in tropical and subtropical coastal environments

Award amount: $1,451,575Duration: 3 yearsFunding agency: NOAA Ocean Acidification Program (OAP), National Oceanographic Partnership Program (NOPP) Why we care Growing seaweed in the ocean could be one way to alleviate some of the impacts by climate change and ocean acidification. We need to know how much carbon can be captured by cultivated seaweed and the potential […]

Assessing the chemical and biological implications of alkalinity enhancement using carbonate salts from captured carbon dioxide to mitigate ocean acidification and enable mCDR

Why we care Energy, manufacturing and deployment costs are critical to the viability of any carbon dioxide removal approach. This research project focuses on a new strategy that promises low energy burden and low manufacturing costs to capture carbon and achieve ocean alkalinity enhancement, essential features for scaling any future efforts of this technology to

Moored Observations of Ocean Carbon System Variables in the Southern California Current Ecosystem

This project will deploy two interdisciplinary moorings (CCE1 and CCE2) in the southern California Current System, a key coastal upwelling ecosystem along the west coast of North America. The study region forms the dominant spawning habitat for most of the biomass of small pelagic fishes in the entire California Current System, is important for wild harvest of diverse marine invertebrates and fishes, plays a significant role in the ocean carbon budget for the west coast, and is in close proximity to the Channel Islands National Marine Sanctuary. The offshore CCE1 mooring is located in the core flow of the California Current itself, and represents a key source of horizontal transport of nutrients, dissolved gases, and organisms from higher latitudes. It also represents the offshore atmosphere-ocean gas exchange that occurs over a large area and influences the carbon budget of this Eastern Boundary Current. The CCE2 mooring is located near Pt. Conception, one of the major upwelling centers off the west coast. This is a site of strong, episodic upwelling events that lead to marked increases in pCO2, declines in pH and dissolved oxygen, and intrusion of waters unfavorable to precipitation of calcium carbonate by some shell-bearing marine organisms. The proposed work will regularly deploy and service taut line, bottom-anchored moorings at the two mooring sites, with sensors designed to measure all core carbonate system variables specified by the PMEL OA Monitoring Network. The data will be validated with shipboard measurements and rigorous QC procedures, and made freely available via Iridium satellite telemetry. Complementary measurements made by partners in this region include Spray glider-based assessments of calcium carbonate saturation state, CalCOFI shipboard hydrographic and plankton food web measurements, process studies conducted by the CCE-LTER (Long Term Ecological Research) site, and a new experimental Ocean Acidification facility.

ADAPTING TO OCEAN ACIDIFICATION

The NOAA Ocean Acidification Program (OAP) works to prepare society to adapt to the consequences of ocean acidification and conserve marine ecosystems as acidification occurs. Learn more about the human connections and adaptation strategies from these efforts.

Adaptation approaches fostered by the OAP include:

FORECASTING

Using models and research to understand the sensitivity of organisms and ecosystems to ocean acidification to make predictions about the future, allowing communities and industries to prepare

MANAGEMENT

Using these models and predictions as tools to facilitate management strategies that will protect marine resources and communities from future changes

TECHNOLOGY DEVELOPMENT

Developing innovative tools to help monitor ocean acidification and mitigate changing ocean chemistry locally

REDUCING OUR CARBON FOOTPRINT

On the Road

Drive fuel-efficient vehicles or choose public transportation. Choose your bike or walk! Don't sit idle for more than 30 seconds. Keep your tires properly inflated.

With your Food Choices

Eat local- this helps cut down on production and transport! Reduce your meat and dairy. Compost to avoid food waste ending up in the landfill

With your Food Choices

Make energy-efficient choices for your appliances and lighting. Heat and cool efficiently! Change your air filters and program your thermostat, seal and insulate your home, and support clean energy sources

By Reducing Coastal Acidification

Reduce your use of fertilizers, Improve sewage treatment and run off, and Protect and restore coastal habitats

TAKE ACTION WITH YOUR COMMUNITY

You've taken the first step to learn more about ocean acidification - why not spread this knowledge to your community?

Every community has their unique culture, economy and ecology and what’s at stake from ocean acidification may be different depending on where you live.  As a community member, you can take a larger role in educating the public about ocean acidification. Creating awareness is the first step to taking action.  As communities gain traction, neighboring regions that share marine resources can build larger coalitions to address ocean acidification.  Here are some ideas to get started:

  1. Work with informal educators, such as aquarium outreach programs and local non-profits, to teach the public about ocean acidification. Visit our Education & Outreach page to find the newest tools!
  2. Participate in habitat restoration efforts to restore habitats that help mitigate the effects of coastal acidification
  3. Facilitate conversations with local businesses that might be affected by ocean acidification, building a plan for the future.
  4. Partner with local community efforts to mitigate the driver behind ocean acidification  – excess CO2 – such as community supported agriculture, bike & car shares and other public transportation options.
  5. Contact your regional Coastal Acidification Network (CAN) to learn how OA is affecting your region and more ideas about how you can get involved in your community
