Abstract Aragonite saturation state (Ω arag ) in surface and subsurface waters of the global oceans was calculated from up‐to‐date (through year 2012) ocean station dissolved inorganic carbon (DIC) total alkalinity (TA) data. Surface Ω open always supersaturated > 1), ranging between 1.1 4.2. It above 2.0 (2.0–4.2) 40°N 40°S but decreased toward higher latitude to below 1.5 polar areas. The influences water temperature on TA/DIC ratio, combined with effects equilibrium apparent solubility...
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...
Over the past several years researchers have been working to synthesize WOCE/JGOFS global CO 2 survey data better understand carbon cycling processes in oceans. The Pacific Ocean set has over 35,000 sample locations with at least two parameters, oxygen, nutrients, CFC tracers, and hydrographic parameters. In this paper we estimate situ CaCO 3 dissolution rates water column. Calcium carbonate ranging from 0.01–1.1 μmol kg −1 yr are observed intermediate deepwater beginning near aragonite...
Based on measurements from the WOCE/JGOFS global CO 2 survey, CLIVAR/CO Repeat Hydrography Program and Canadian Line P we have observed an average decrease of 0.34% yr −1 in saturation state surface seawater Pacific Ocean with respect to aragonite calcite. The upward migrations calcite horizons, averaging about 1 m , are direct result uptake anthropogenic by oceans regional changes circulation biogeochemical processes. shoaling horizon is regionally variable, more rapid South where there a...
Significance Seawater elemental composition, namely Mg:Ca and Sr:Ca ratios are widely used in marine sciences. Our new single-laboratory global dataset, combined with past data of seawater ratios, suggests that modern ocean variability is significant across different environments, being similar to the changes during Neogene Period (20 Ma). Because there large we cannot assume secular derived from fossilized taxa varied ecological niches diverse ecosystems provide an unbiased representation...
A successful integrated ocean acidification (OA) observing network must include 1) scientists and technicians from a range of disciplines (from physics to chemistry biology technology development) across the globe; 2) government, private, intergovernmental support; 3) regional cohorts working together on regionally specific issues; 4) publicly accessible data open coastal estuarine systems; 5) close integration with other networks focusing related measurements or issues including social...
Abstract The California Current Ecosystem (CCE) is a natural laboratory for studying the chemical and ecological impacts of ocean acidification. Biogeochemical variability in region due primarily to wind‐driven near‐shore upwelling cold waters that are rich re‐mineralized carbon poor oxygen. coastal regions exposed surface with increasing concentrations anthropogenic CO 2 (C anth ) from exchanges atmosphere shoreward transport mixing upwelled water. drives intense cycling organic matter...
This study uses nearly 25,000 carbon measurements from the WOCE/JGOFS global CO 2 survey to examine distribution of dissolved inorganic (DIC) and total alkalinity (TA) in Indian Ocean. Shallow intermediate distributions do not strictly follow temperature salinity because differing surface gradients vertical biological processes that work modify circulation derived features. Anthropogenic has increased shallow DIC by as much 3%, decreasing gradient. Deep ocean TA increase toward north...
The contribution of carbonate‐producing benthic organisms to the global marine carbon budget has been overlooked, prevailing view being that calcium carbonate (CaCO 3 ) is predominantly produced and exported by plankton in “biological pump.” Here, we provide first estimation echinoderms inorganic organic cycle, based on organism‐level measurements from species five echinoderm classes. Echinoderms' CaCO amounts ~0.861 Pg /yr (0.102 C/yr carbon) as a production rate, ~2.11 (0.25 C standing...
This paper uses the extended multiple linear regression (eMLR) technique to investigate changes over last decade in dissolved inorganic carbon (DIC) inventories on a meridional line (P16 along 152°W) up central Pacific and zonal (P02 30°N) across North Pacific. Maximum total DIC concentrations P02 are 15–20 μ mol kg −1 10 years, somewhat higher than ∼1 increase expected based rate of atmospheric CO 2 increase. The maximum P16 14/15‐year time frame fit with magnitude anthropogenic signal, but...
Abstract. Internally consistent, quality-controlled (QC) data products play an important role in promoting regional-to-global research efforts to understand societal vulnerabilities ocean acidification (OA). However, there are currently no such for the coastal ocean, where most of OA-susceptible commercial and recreational fisheries aquaculture industries located. In this collaborative effort, we compiled, quality-controlled, synthesized 2 decades discrete measurements inorganic carbon...

Coastal and estuarine waters of the northern California Current system southern Salish Sea host an observational network capable characterizing biogeochemical dynamics related to ocean acidification, hypoxia, marine heatwaves. Here, we compiled data sets from a set cruises conducted in Puget Sound (southern Sea) its boundary (Strait Juan de Fuca Washington coast). This product provides decade with consistent formatting, extended quality control, multiple units for parameters such...
Abstract. Coastal and estuarine ecosystems fringing the North Pacific Ocean are particularly vulnerable to ocean acidification, hypoxia, intense marine heatwaves as a result of interactions among natural anthropogenic processes. Here, we characterize variability during seasonally resolved cruise time series (2014–2018) in southern Salish Sea (Puget Sound, Strait Juan de Fuca) nearby coastal waters for select physical (temperature, T; salinity, S) biogeochemical (oxygen, O2; carbon dioxide...
