Seasonal Variations of Carbonate Chemistry at Two Western Atlantic Coral Reefs
Anthropogenic activities, such as the burning of fossil fuels, interact with the chemistry of the ocean surface and cause ocean acidification (OA). The current trend and projections for OA are well defined for open ocean waters, although less is known about its effects on nearshore ecosystems, where most of the affected organisms reside. In this

Physiological feeding rates and cilia suppression in blue mussels (<em>Mytilus edulis</eM>) with increased levels of dissolved carbon dioxide
Gills of marine bivalves, the organs that mediate water flow for feeding and other physiological functions, are exposed to increasing levels of carbon dioxide (CO2) in seawater, in response to ocean acidification (OA). We examined the effects of elevated dissolved CO2 upon filtration and feeding behavior of the blue mussel, Mytilus edulis, under field conditions and in laboratory

Evaluation of a New Carbon Dioxide System for Autonomous Surface Vehicles
The research evaluates a new Autonomous Surface Vehicle CO2 (ASVCO2) system designed to improve carbon measurement in the ocean, addressing gaps in current strategies that hinder understanding of the carbon biogeochemical cycle. Deployed from 2011 to 2018, the ASVCO2 systems demonstrated their capability for long-term oceanic deployment and accurate collection of air and seawater pCO2

Carbonate chemistry seasonality in a tropical mangrove lagoon in La Parguera, Puerto Rico
We investigated the seasonal carbonate chemistry variability within a semi-enclosed tropical mangrove lagoon in southwestern Puerto Rico. Biweekly measurements of seawater temperature, salinity, total alkalinity (TA), and dissolved inorganic carbon (DIC) were conducted from 2014 to 2018. We describe the possible mechanisms driving the observed variability by correlating the DIC/TA ratio with pH and Ωarg,

Irradiance, photosynthesis and elevated pCO<sub>2</sub> effects on net calcification in tropical reef macroalgae
Calcifying tropical macroalgae produce sediment, build three-dimensional habitats, and provide substrate for invertebrate larvae on reefs. Thus, lower calcification rates under declining pH and increasing ocean pCO2, or ocean acidification, is a concern. In the present study, calcification rates were examined experimentally under predicted end-of-the-century seawater pCO2 (1116 μatm) and pH (7.67) compared to ambient controls (pCO2 409 μatm; pH 8.04).

Ocean Acidification and Direct Interactions Affect Coral, Macroalga, and Sponge Growth in the Florida Keys
Coral reef community composition, function, and resilience have been altered by natural and anthropogenic stressors. Future anthropogenic ocean and coastal acidification (together termed “acidification”) may exacerbate this reef degradation. Accurately predicting reef resilience requires an understanding of not only direct impacts of acidification on marine organisms but also indirect effects on species interactions that influence

Inorganic Carbon Transport and Dynamics in the Florida Straits
Ocean heat and carbon are transported through the Florida Straits, contributing to the Atlantic Meridional Overturning Circulation, and playing an important role in climate. Insufficient observations of carbonate chemistry within the Florida Straits have limited our understanding of ocean acidification within this region. To examine carbonate chemistry and carbon transport dynamics within this region, we

Climatological distribution of ocean acidification variables along the North American ocean margins
Climatologies that depict mean fields of oceanographic variables on a regular geographic grid, and atlases play pivotal roles in comprehending the societal vulnerabilities linked to ocean acidification (OA). This significance is particularly pronounced in coastal regions where most economic activities occur. This work provides a comprehensive data product featuring 10 coastal ocean acidification climatologies and
