Abstract. Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, terrestrial biosphere in a changing climate – “global budget” is important to better understand global cycle, support development policies, project future change. Here we describe synthesize data sets methodology quantify five major components budget uncertainties. Fossil CO2 (EFOS) are based on energy statistics cement production data, while from land-use...

Abstract. The Surface Ocean CO2 Atlas (SOCAT), an activity of the international marine carbon research community, provides access to synthesis and gridded fCO2 (fugacity dioxide) products for surface oceans. Version 2 SOCAT is update previous release (version 1) with more data (increased from 6.3 million 10.1 water values) extended coverage (from 1968–2007 1968–2011). quality control criteria, while identical in both versions, have been applied strictly version than 1. website...
The highly productive fisheries of Alaska are located in seas projected to experience strong global change, including rapid transitions temperature and ocean acidification-driven changes pH other chemical parameters. Many the marine organisms that most intensely affected by acidification (OA) contribute substantially state's commercial traditional subsistence way life. Prior studies OA's potential impacts on human communities have focused only possible direct economic losses from specific...

Marine carbon dioxide (CO2) system data has been collected from December 2014 to June 2018 in the northern Salish Sea (NSS; British Columbia, Canada) and consisted of continuous measurements at two sites as well spatially- seasonally-distributed discrete seawater samples. The array CO2 observing activities included high-resolution partial pressure (pCO2) pHT (total scale) made Hakai Institute's Quadra Island Field Station (QIFS) an Environment Canada weather buoy, respectively, pCO2 total...

Abstract. Ocean acidification is the hydrogen ion increase caused by oceanic uptake of anthropogenic CO2, and a focal point in marine biogeochemistry, part, because this chemical reaction reduces calcium carbonate (CaCO3) saturation states (Ω) to levels that are corrosive (i.e., Ω ≤ 1) shell-forming organisms. However, other processes can drive CaCO3 corrosivity; specifically, addition tidewater glacial melt. Carbonate system data collected May September from 2009 through 2012 Prince William...
Abstract. A quantification of carbon fluxes in the coastal ocean and across its boundaries with atmosphere, land, open is important for assessing current state projecting future trends uptake acidification, but this currently a missing component global budgeting. This synthesis reviews recent progress characterizing these North American ocean. Several observing networks high-resolution regional models are now available. Recent efforts have focused primarily on quantifying net air–sea...
Abstract Coastal upwelling regimes are some of the most productive ecosystems in ocean but also among vulnerable to acidification (OA) due naturally high background concentrations CO2. Yet our ability predict how these will respond additional CO2 resulting from anthropogenic emissions is poor. To help address this uncertainty, researchers perform manipulative experiments where biological responses evaluated across different partial pressure (pCO2) levels. In systems, however, contemporary...
Assessing the status of ocean acidification across and coastal waters requires standardized procedures at all levels data collection, dissemination, analysis. Standardized for assuring quality accessibility carbonate chemistry are largely established, but a common set best practices trend analysis is needed to enable global time series comparisons, establish accurate records change, communicate current within outside scientific community. Here we expand upon several published techniques...
[1] Previous work has shown that the Oregon shelf is a sink for atmospheric carbon dioxide (CO2) during upwelling season; however, until now, summertime variability in CO2 exchange and sign of flux rest year were unknown. Observations partial pressure (pCO2) surface waters from August 2007 to May 2010 ships buoy used with historical data produce composite seasonal cycle central midshelf. These indicate region highly variable, at times being either or strong source CO2. Interannual wind was...

Abstract The biogeochemical seascape of the western Arctic coastal ocean is in rapid transition. Changes sea ice cover will be accompanied by alterations sea‐air carbon dioxide (CO 2 ) exchange, which latter has been difficult to constrain owing sparse temporal and spatial data sets. Previous assessments CO flux have targeted specific subregional areas ocean. Here a holistic approach taken determine net over this broad region. We compiled analyzed an extensive set nearly 600,000 surface...
Abstract Less than three decades ago only a small fraction of the Arctic Ocean (AO) was ice free and then for short periods. The cover kept sea surface p CO 2 at levels lower relative to other ocean basins that have been exposed year round ever increasing atmospheric levels. In this study, we evaluate measurements collected over 6‐year period along fixed cruise track in Canada Basin. show mean are significantly higher during low years. increase is likely driven by heating uptake with large...
Abstract During summer, upwelled water with elevated CO 2 partial pressure (pCO ) and nutrients outcrops over the Oregon (OR) inner shelf. As this transits across shelf, high rates of primary production fueled by results in net atmospheric drawdown. Upwelled source‐waters typically have pCO approaching 1000 µatm that is then reduced to ∼200 µatm. For almost entire month July 2008, strong persistent upwelling brought cold (∼8°C), saline (∼33.5), high‐pCO (>600 µatm) our midshelf buoy site,...
The carbonate system in two contrasting fjords, Rivers Inlet and Bute Inlet, on the coast of British Columbia, Canada, was evaluated to characterize mechanisms driving chemistry dynamics assess impact anthropogenic carbon. Differences character deep water exchange between these fjords were inferred from their degree exposure continental shelf salinity relationships with total alkalinity dissolved inorganic carbon, which determined seawater buffering capacity. Seawater capacity differed...
Abstract Regional differences in water properties and responses to stressors are key understanding ecosystem vulnerabilities coastal regions globally. Our study focuses on Canada's British Columbia waters, from Queen Charlotte Strait the of Georgia. This area is bisected by shallow, narrow, tidally mixed channels with some strongest tidal currents world. We examine between either side this constriction, focusing physical three potential biogeochemical stressors: nutrient levels, marine...
Abstract. Information on marine CO2 system variability has been limited along the northeast Pacific Inside Passage despite region's rich biodiversity, abundant fisheries, and developing aquaculture industry. Beginning in 2017, Alaska Marine Highway System M/V Columbia served as a platform for surface underway data collection while conducting twice weekly ∼1600 km transits between Bellingham, Washington, Skagway, Alaska. patterns were evaluated using measurements made over 2-year period,...
