Disparate responses of carbonate system in two adjacent subtropical estuaries to the influence of Hurricane Harvey - A case study
(Frontiers in Marine Science, 2020-01-31)
Two adjacent estuaries in the northwestern Gulf of Mexico (GOM) (Mission–Aransas or MAE and Guadalupe–San Antonio or GE), despite their close proximity and similar extents of freshening caused by Hurricane Harvey, exhibited ...
Photomineralization of organic carbon in a eutrophic, semiarid estuary
(2020-01-28)
The effect of photomineralization on the carbon cycle in a eutrophic, semiarid estuary (Baffin Bay, Texas) was investigated using closed‐system incubations. Photochemical production rate of dissolved inorganic carbon ranged ...
Carbon cycling in the North American coastal ocean: a synthesis
(2019-03-27)
A quantification of carbon fluxes in the coastal ocean and across its boundaries with the atmosphere, land, and the open ocean is important for assessing the current state and projecting future trends in ocean carbon uptake ...
Coral Energy Reserves and Calcification in a High-CO2 World at Two Temperatures
(2013-10-11)
Rising atmospheric CO2 concentrations threaten coral reefs globally by causing ocean acidification (OA) and warming. Yet, the combined effects of elevated pCO2 and temperature on coral physiology and resilience remain ...
Physiological response to elevated temperature and pCO2 varies across four Pacific coral species: Understanding the unique host+symbiont response
(2015-12-16)
The physiological response to individual and combined stressors of elevated temperature and pCO2 were measured over a 24-day period in four Pacific corals and their respective symbionts (Acropora millepora/Symbiodinium ...
Continental shelves as a variable but increasing global sink for atmospheric carbon dioxide
(2018-01-31)
It has been speculated that the partial pressure of carbon dioxide (pCO2) in shelf waters may lag the rise in atmospheric CO2. Here, we show that this is the case across many shelf regions, implying a tendency for enhanced ...
Microelectrode characterization of coral daytime interior pH and carbonate chemistry
(2016-04-04)
Reliably predicting how coral calcification may respond to ocean acidification and warming depends on our understanding of coral calcification mechanisms. However, the concentration and speciation of dissolved inorganic ...
Time of Emergence of Surface Ocean Carbon Dioxide Trends in the North American Coastal Margins in Support of Ocean Acidification Observing System Design
(2019-03-08)
Time of Emergence (ToE) is the time when a signal emerges from the noise of natural variability. Commonly used in climate science for the detection of anthropogenic forcing, this concept has recently been applied to ...
Organic carbon fluxes mediated by corals at elevated pCO2 and temperature
(Marine Ecology Progress Series, 2015-01-20)
Increasing ocean acidification (OA) and seawater temperatures pose significant threats to coral reefs globally. While the combined impacts of OA and seawater temperature on coral biology and calcification in corals have ...
