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

Determining the Influence of Ocean Alkalinity Enhancement on Foraminifera Calcification, Distribution, and Calcium carbonate Production
Why we care Foraminifera, or forams, are single-celled organisms that produce calcium carbonate shells and play a crucial role in the ocean’s carbon cycle. Ocean alkalinity enhancement aims to increase the ocean’s ability to absorb carbon dioxide by enhancing its buffering capacity. However, the impact of the addition of alkalinity on foraminifera is not well

Quantifying the Efficacy of Wastewater Alkalinity Enhancement on mCDR and Acidification Mitigation in a Large Estuary
Why we care Manipulating wastewater treatment plant procedures and discharge to enhance carbon removal is practical because of the current readiness of infrastructure to deliver alkalinity to the coastal ocean. Many wastewater facilities already treat wastewater with alkalinity, permits to allow alkalinity discharge already exist, and there are several known technologies that can increase alkalinity

Data requirements for quantifying natural variability and the background ocean carbon sink in mCDR models
Why we care Ocean uptake of carbon has great natural variability that accompanies rising atmospheric carbon dioxide. A major challenge for marine carbon dioxide removal will be to quantify its additional carbon removal from the atmosphere. Ocean models can quantify carbon uptake attributed to marine carbon dioxide removal will likely be the basis for carbon

Ocean acidification in the Gulf of Mexico: Drivers, impacts, and unknowns
We synthesize the current peer-reviewed literature on Gulf of Mexico (GOM) acidification across the ocean-estuarine continuum and identify critical knowledge, research, and monitoring gaps that limit our current understanding of environmental, ecological, and socioeconomic impacts from acidification.• The GOM remains a relatively understudied region with respect to ocean acidification (OA), particularly with respect to regionally important organism and ecosystem responses.• Within the GOM,

Interactions between ocean acidification and metal contaminant uptake by Blue Mussels
Assessing ocean acidification as a driver for enhanced metals uptake by Blue mussels (Mytilus edulis): implications for aquaculture and seafood safety
Why we care
Ocean acidification causes changes in the chemistry of stressors such as metals and may affect both the susceptibility of these animals to the contaminants as well as the toxicity. This is

Evaluating impacts of acidification on biological processes in the Gulf of Mexico
Evaluation of OA impacts to plankton and fish distributions in the Gulf of Mexico during GOMECC-4 with a focus on HAB-interactions
Why we care
Ocean change in the Gulf of Mexico, including acidification and eutrophication, can impact biodiversity and the flow of energy through ecosystems from microscopic phytoplankton to higher trophic levels like fish. These

Coastal Acidification
Understanding biodiversity in the Gulf of Mexico using eDNA
Assessing ecosystem responses of Gulf of Mexico coastal communities to ocean acidification using environmental DNA
Why we care
Recent efforts to monitor ocean acidification in the Gulf of Mexico via the Gulf of Mexico Ecosystems and Carbon Cycle (GOMECC) cruises have revealed spatial differences in ocean acidification. While we know that ocean acidification negatively impacts

Ocean acidification interactions in the Gulf of Mexico
Ocean Acidification on a Crossroad: Enhanced Respiration, Upwelling, Increasing Atmospheric CO2, and their interactions in the northwestern Gulf of Mexico
Why we care
In the coastal ocean, local drivers such as nutrient input and physical oceanographic changes impact the magnitude of short-term variations and long-term trends in ocean acidification. The Gulf of Mexico’s coral
