Abstract. The Surface Ocean CO2 Atlas (SOCAT) is a synthesis of quality-controlled fCO2 (fugacity carbon dioxide) values for the global surface oceans and coastal seas with regular updates. Version 3 SOCAT has 14.7 million from 3646 data sets covering years 1957 to 2014. This latest version an additional 4.6 relative 2 extends record 2011 also significantly increases availability 2005 2013. average approximately 1.2 water per year 2006 2012. Quality documentation improved. A new feature set...
The pH, alkalinity (Alk), and dissolved inorganic carbon (DIC) in estuarine waters of several rivers Georgia the southeastern United States are reported. Although they discharge into a narrow area South Atlantic Bight, along coast differ significantly their drainage (Piedmont vs. coastal plain rivers), chemical composition (contents carbonate humics), rates. Large differences DIC, Alk between these clearly reflect material inputs to rivers. Dramatic pH increases early stage mixing (more...
Hydrogen sulfide (H(2)S) has been reported to be a gasotransmitter which regulates cardiovascular homeostasis. The present study aims examine the hypothesis that hydrogen is able promote angiogenesis.Angiogenesis was assessed using in vitro parameters (i.e. endothelial cell proliferation, adhesion, transwell migration assay, scratched wound healing and formation of tube-like structure) vivo by assessing neovascularization mice. Phosphorylation Akt measured Western blot analysis.Exogenously...
In determining global sea‐to‐air CO 2 flux from measurements or models, the ocean margin has not been resolved land open ocean. Recent studies have indicated that shelves can be either a large sink source for atmospheric . This sink/source term may substantially alter our current view of carbon budget and oceans. However, past fieldwork synthesis focused on few in northern temperate zone while vast majority other are ignored. By dividing highly heterogeneous into seven provinces, we suggest...

Mesoscale eddies may play a critical role in ocean biogeochemistry by increasing nutrient supply, primary production, and efficiency of the biological pump, that is, ratio carbon export to production otherwise nutrient-deficient waters. We examined diatom bloom within cold-core cyclonic eddy off Hawai`i. Eddy community biomass, size composition were markedly enhanced but had little effect on ratio. Instead, system functioned as selective silica pump. Strong trophic coupling inefficient...
It has been predicted that the Arctic Ocean will sequester much greater amounts of carbon dioxide (CO2) from atmosphere as a result sea ice melt and increasing primary productivity. However, this prediction was made on basis observations either highly productive ocean margins or ice-covered basins before recent major retreat. We report here high-resolution survey sea-surface CO2 concentration across Canada Basin, showing great increase relative to earlier observations. Rapid invasion low...
Abstract. A well-documented, publicly available, global data set of surface ocean carbon dioxide (CO2) parameters has been called for by international groups nearly two decades. The Surface Ocean CO2 Atlas (SOCAT) project was initiated the marine science community in 2007 with aim providing a comprehensive, regularly updated, CO2, which had subject to quality control (QC). Many additional data, not yet made public via Carbon Dioxide Information Analysis Center (CDIAC), were retrieved from...
Coastal hypoxia is an increasingly recognized environmental issue of global concern to both the scientific community and general public. We assessed relative contributions from marine terrestrially sourced organic matter that were responsible for oxygen consumption in a well-studied seasonal coastal hypoxic zone, East China Sea off Changjiang Estuary. Our fieldwork was conducted August 2011 during reinstatement subsurface hypoxia, when we observed continuous decline dissolved along with...
Increasing atmospheric carbon dioxide (CO(2)) is raising seawater CO(2) concentrations and thereby acidifying ocean water. But a second environmental problem, eutrophication, also causing large inputs into coastal waters. This occurs because anthropogenic of nutrients have fueled massive algal blooms, which deplete bottom waters oxygen (O(2)) release when the organic matter from these blooms respired by bacteria. On basis biogeochemical model, are predicted to decrease current pH values 0.25...
Abstract Carbon cycling in the coastal zone affects global carbon budgets and is critical for understanding urgent issues of hypoxia, acidification, tidal wetland loss. However, there are no regional spanning three main ecosystems waters: wetlands, estuaries, shelf waters. Here we construct such a budget eastern North America using historical data, empirical models, remote sensing algorithms, process‐based models. Considering net fluxes total at domain boundaries, 59 ± 12% (± 2 standard...
It has been speculated that the partial pressure of carbon dioxide (pCO2) in shelf waters may lag rise atmospheric CO2. Here, we show this is case across many regions, implying a tendency for enhanced uptake This result based on analysis long-term trends air-sea pCO2 gradient (ΔpCO2) using global surface ocean database spanning period up to 35 years. Using wintertime data only, find ΔpCO2 increased 653 825 0.5° cells which trend could be calculated, with 325 these showing significant...
This review examines the current understanding of global coastal ocean carbon cycle and provides a new quantitative synthesis air-sea CO 2 exchange. reanalysis yields an estimate for globally integrated flux −0.25 ± 0.05 Pg C year −1 , with polar subpolar regions accounting most removal (>90%). A framework that classifies river-dominated margin (RiOMar) ocean-dominated (OceMar) systems is used to conceptualizecoastal processes. The dynamics in three contrasting case study regions, Baltic...
The Arctic Ocean has experienced rapid warming and sea ice loss in recent decades, becoming the first open-ocean basin to experience widespread aragonite undersaturation [saturation state of (Ωarag) < 1]. However, its trend toward long-term ocean acidification underlying mechanisms remain undocumented. Here, we report there, with rates three four times higher than other basins, attribute it changing coverage on a decadal time scale. Sea melt exposes seawater atmosphere promotes uptake...
Effective data management plays a key role in oceanographic research as cruise-based data, collected from different laboratories and expeditions, are commonly compiled to investigate regional global processes. Here we describe new updated best practice standards for discrete chemical observations, specifically those dealing with column header abbreviations, quality control flags, missing value indicators, standardized calculation of certain properties. These have been developed the goals...
Abstract To facilitate wind energy use and avoid low returns, or even losses in extreme cases, this paper proposes an integrated risk measurement control approach to jointly manage multiple statistical properties of the expected profit distribution for a storage system. First, risk-averse stochastic decision-making framework multi-type measurements, including conditional value at Risk (CVaR), (VaR) shortfall probability (SP), are described detail. satisfy various needs decision makers,...
Abstract The coastal ocean contributes to regulating atmospheric greenhouse gas concentrations by taking up carbon dioxide (CO 2 ) and releasing nitrous oxide (N O) methane (CH 4 ). In this second phase of the Regional Carbon Cycle Assessment Processes (RECCAP2), we quantify global fluxes CO , N O CH using an ensemble gap‐filled observation‐based products biogeochemical models. is a net sink in both observational models, but magnitude median uptake ∼60% larger models (−0.72 vs. −0.44 PgC...
