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:: This is PMEL Contribution 4396. Acidification has sparked discussion about whether regulatory agencies should place coastal waters on the Clean Water Act 303(d) impaired water bodies list. Here we describe scientific challenges in assessing impairment with existing data, exploring use of both pH and biological criteria. Application of pH criteria...

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...

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:: 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...

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...
