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...

We quantify the oceanic sink for anthropogenic carbon dioxide (CO2) over period 1994 to 2007 by using observations from global repeat hydrography program and contrasting them 1990s. Using a linear regression-based method, we find increase in CO2 inventory of 34 ± 4 petagrams (Pg C) between 2007. This is equivalent an average uptake rate 2.6 0.3 Pg C year-1 represents 31 4% emissions this period. Although ocean estimate consistent with expectation having increased proportion rise atmospheric...

Present global warming is amplified in the Arctic and accompanied by unprecedented sea ice decline. Located along main pathway of Atlantic Water entering Arctic, Barents Sea site coupled feedback processes that are important for creating variability entire air‐ice‐ocean system. As warm flows through Sea, it loses heat to atmosphere. Warm periods, like today, associated with high northward transport, reduced cover, surface air temperatures. The cooling inflow creates dense water sinking great...
Abstract. We present a mapped climatology (GLODAPv2.2016b) of ocean biogeochemical variables based on the new GLODAP version 2 data product (Olsen et al., 2016; Key 2015), which covers all basins over years 1972 to 2013.

The ocean's chemistry is changing due to the uptake of anthropogenic carbon dioxide (CO2). This phenomenon, commonly referred as "Ocean Acidification", endangering coral reefs and broader marine ecosystems. In this study, we combine a recent observational seawater CO2 data product, i.e., 6th version Surface Ocean Atlas (1991-2018, ~23 million observations), with temporal trends at individual locations global ocean from robust Earth System Model provide high-resolution regionally varying view...
Abstract. Using measurements of the surface-ocean CO2 partial pressure (pCO2) and 14 different pCO2 mapping methods recently collated by Surface Ocean Mapping intercomparison (SOCOM) initiative, variations in regional global sea–air fluxes are investigated. Though available use widely approaches, we find relatively consistent estimates seasonality, line with previous estimates. In terms interannual variability (IAV), all estimate largest to occur eastern equatorial Pacific. Despite...
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...
Abstract. A temporally and spatially resolved estimate of the global surface-ocean CO2 partial pressure field sea–air flux is presented, obtained by fitting a simple data-driven diagnostic model ocean mixed-layer biogeochemistry to data from SOCAT v1.5 database. Results include seasonal, interannual, short-term (daily) variations. In most regions, estimated seasonality well constrained data, compares widely used monthly climatology Takahashi et al. (2009). Comparison independent tentatively...
Abstract. Interannual anomalies in the sea–air carbon dioxide (CO2) exchange have been estimated from surface-ocean CO2 partial pressure measurements. Available data are sufficient to constrain these large parts of tropical and North Pacific Atlantic, some areas covering period mid 1980s 2011. Global interannual variability is as about 0.31 Pg C yr−1 (temporal standard deviation 1993–2008). The accounts for a fraction this global variability, closely tied El Niño–Southern Oscillation (ENSO)....

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...
