Air-water CO₂ fluxes in the microtidal Neuse River Estuary, North Carolina

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...

Iron links river runoff and shelf width to phytoplankton biomass along the U.S. West Coast

Creator:: Chase, Zanna, Strutton, Peter G., and Hales, Burke
Abstract:: A poleward increase in phytoplankton biomass along the West Coast of North America has been attributed to increasing river runoff towards the north. We combine streamflow and shelf width data with satellite-derived estimates of phytoplankton biomass to quantify the relationship between these variables. We find that a combination of winter...

Riverine input of macronutrients, iron, and organic matter to the coastal ocean off Oregon, U.S.A., during the winter

Creator:: Wetz, Michael S., Hales, Burke, Chase, Zanna, Wheeler, Patricia A., and Whitney, Michael M.
Abstract:: Three cross‐shelf transects were conducted off northern Oregon in February, 2003, coincident with flooding of Coast Range rivers, to assess the riverine impact on coastal ocean biogeochemistry. During downwelling conditions, low salinity river‐influenced water was located in a narrow band near the coast and contained elevated macronutrient, iron, and organic...

Extensive CO₂ emissions from shallow coastal waters during passage of Hurricane Irene (August 2011) over the Mid-Atlantic Coast of the U.S.A.

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...

Ocean Acidification Has Multiple Modes of Action on Bivalve Larvae

Creator:: Waldbusser, George G., Hales, Burke, Langdon, Chris J., Haley, Brian A., Schrader, Paul, Brunner, Elizabeth L., Gray, Matthew W., Miller, Cale A., Gimenez, Iria, and Hutchinson, Greg
Abstract:: Ocean acidification (OA) is altering the chemistry of the world’s oceans at rates unparalleled in the past roughly 1 million years. Understanding the impacts of this rapid change in baseline carbonate chemistry on marine organisms needs a precise, mechanistic understanding of physiological responses to carbonate chemistry. Recent experimental work has...

The Pacific oyster, Crassostrea gigas, shows negative correlation to naturally elevated carbon dioxide levels: Implications for near-term ocean acidification effects

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)...

Water quality criteria for an acidifying ocean: Challenges and opportunities for improvement

Creator:: Weisberg, Stephen B., Bednaršek, Nina, Feely, Richard A., Chan, Francis, Boehm, Alexandria B., Sutula, Martha, Ruesink, Jennifer L., Hales, Burke, Largier, John L., and Newton, Jan A.
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...

Impacts of Coastal Acidification on the Pacific Northwest Shellfish Industry and Adaptation Strategies Implemented in Response

Creator:: Barton, Alan, Waldbusser, George G., Feely, Richard A., Weisberg, Stephen B., Newton, Jan A., Hales, Burke, Cudd, Sue, Eudeline, Benoit, Langdon, Chris J., Jefferds, Ian, King, Teri, Suhrbier, Andy, and McLaughlin, Karen
Abstract:: In 2007, the US west coast shellfish industry began to feel the effects of unprecedented levels of larval mortality in commercial hatcheries producing the Pacific oyster Crassostrea gigas. Subsequently, researchers at Whiskey Creek Shellfish Hatchery, working with academic and government scientists, showed a high correlation between aragonite saturation state (Ω[subscript]arag)...

Global calcite cycling constrained by sediment preservation controls

Creator:: Dunne, John P., Hales, Burke, and Toggweiler, J. R.
Abstract:: We assess the global balance of calcite export through the water column and burial in sediments as it varies regionally. We first drive a comprehensive 1-D model for sediment calcite preservation with globally gridded field observations and satellite-based syntheses. We then reformulate this model into a simpler five-parameter box model,...

How Can Present and Future Satellite Missions Support Scientific Studies that Address Ocean Acidification?

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...
