Creator:: Crosswell, Joseph R., Wetz, Michael S., Hales, Burke, and Paerl, Hans W.
Abstract:: From June 2009 to July 2010, we conducted 27 continuous-flow surveys of surface water CO₂ partial pressure (pCO₂) along the longitudinal axis of the Neuse River Estuary (NRE), North Carolina ranging from the tidal freshwater region to the polyhaline border with the Pamlico Sound. Lateral transects were also conducted at...

Abstract:: Understanding larval bivalve responses to variable regimes of seawater carbonate chemistry requires realistic quantification of physiological stress. Based on a degree-day modeling approach, we developed a new metric, the ocean acidification stress index for shellfish (OASIS), for this purpose. OASIS integrates over the entire larval period the instantaneous stress associated...

Creator:: Harris, Katherine E., DeGrandpre, Michael D., and Hales, Burke
Abstract:: Abstract: Coastal upwelling zones may be at enhanced risk from ocean acidification as upwelling brings low aragonite saturation state (Ω[subscript Ar]) waters to the surface that are further suppressed by anthropogenic CO₂. Ω[subscript Ar] was calculated with pH, pCO₂, and salinity-derived alkalinity time series data from autonomous pH and pCO₂...

Abstract:: Space-based observations offer unique capabilities for studying spatial and temporal dynamics of the upper ocean inorganic carbon cycle and, in turn, supporting research tied to ocean acidification (OA). Satellite sensors measuring sea surface temperature, color, salinity, wind, waves, currents, and sea level enable a fuller understanding of a range of...

Creator:: Barton, Alan, Hales, Burke, Waldbusser, George G., Langdon, Chris, and Feely, Richard A.
Abstract:: We report results from an oyster hatchery on the Oregon coast, where intake waters experienced variable carbonate chemistry (aragonite saturation state < 0.8 to > 3.2; pH < 7.6 to > 8.2) in the early summer of 2009. Both larval production and midstage growth (∼ 120 to ∼ 150 µm)...

Creator:: Kavanaugh, Maria T., Emerson, Steven R., Hales, Burke, Lockwood, Deirdre M., Quay, Paul D., and Letelier, Ricardo M.
Abstract:: The subarctic-subtropical transition zone in the North Pacific represents the second largest sink of atmospheric carbon dioxide in the world ocean, yet the relative importance of physical and biological processes in this uptake is debated. In a step toward understanding the spatiotemporal variability of environmental, physiological, and ecological factors that...

Abstract:: During the Southern Ocean Iron Experiment (SOFeX), January-February 2002, two iron fertilization experiments were conducted at the south (66.45°S, 171.8°W) and north (56.23°S, 172°W) patches. The south patch was replete with all macronutrients, whereas the north patch was nearly depleted of silicate. Using a towed water sampling/measurement system, high resolution...

Creator:: Evans, Wiley, Hales, Burke, and Strutton, Peter G.
Abstract:: Previous work has shown that the Oregon shelf is a sink for atmospheric carbon dioxide (CO₂) during the upwelling season; however, until now, summertime variability in CO₂ exchange and sign of the flux for the rest of the year were unknown. Observations of the partial pressure of CO₂ (pCO₂) in...

Creator:: Crosswell, Joseph R., Wetz, Michael S., Hales, Burke, and Paerl, Hans W.
Abstract:: Shallow coastal waters serve an important role as long-term carbon (C) sinks because they capture terrestrial C and retain internally produced C in wetlands and sediments. We show that tropical cyclones (TCs) can lead to rapid CO₂ efflux from estuaries, driven by physical and biogeochemical perturbation of these coastal C...

Abstract:: Various human activities, including fossil fuel combustion and forest clearing, emit about eight petagrams (or billion tons) of carbon in the form of CO2 into the atmosphere annually. The global ocean absorbs about two petagrams of CO2, and about a half of that amount is absorbed by the Southern Ocean...
