Abstract

The Global Ocean Data Analysis Project (GLODAP) is a synthesis effort providing regular compilations of surface to bottom ocean biogeochemical data, with an emphasis on seawater inorganic carbon chemistry and related variables determined through chemical analysis of water samples. GLODAPv2.2020 is an update of the previous version, GLODAPv2.2019. The major changes are: data from 106 more cruises added, extension of time coverage until 2019, and the inclusion of available discrete fugacity of CO2 (fCO2) values in the merged product files. GLODAPv2.2020 includes measurements from more than 1.2 million water samples from the global oceans collected on 946 cruises. The data for the 12 GLODAP core variables (salinity, oxygen, nitrate, silicate, phosphate, dissolved inorganic carbon, total alkalinity, pH, CFC-11, CFC-12, CFC-113, and CCl4) have undergone extensive quality control, especially systematic evaluation of bias. The data are available in two formats: (i) as submitted by the data originator but updated to WOCE exchange format and (ii) as a merged data product with adjustments applied to minimize bias. These adjustments were derived by comparing the data from the 106 new cruises with the data from the 840 quality-controlled cruises of the GLODAPv2.2019 data product. They correct for errors related to measurement, calibration, and data handling practices, while taking into account any known or likely time trends or variations in the variables evaluated. The compiled and adjusted data product is believed to be consistent to better than 0.005 in salinity, 1 % in oxygen, 2 % in nitrate, 2 % in silicate, 2 % in phosphate, 4 μmol kg−1 in dissolved inorganic carbon, 4 μmol kg−1 in total alkalinity, 0.01–0.02, depending on region, in pH, and 5 % in the halogenated transient tracers. The other variables included in the compilation, such as isotopic tracers and discrete fCO2 were not subjected to bias comparison or adjustments. The original data, their documentation and doi

Abstract

Accurate assessment of anthropogenic carbon dioxide (CO2)emissions and their redistribution among the atmosphere, ocean, andterrestrial biosphere is important to better understand the globalcarbon cycle, support the development of climate policies, and projectfuture climate change. Here we describe datasets and a methodology toquantify all major components of the global carbon budget, includingtheir uncertainties, based on the combination of a range of data,algorithms, statistics and model estimates and their interpretation by abroad scientific community. We discuss changes compared to previousestimates, consistency within and among components, alongsidemethodology and data limitations. CO2 emissions from fossilfuel combustion and cement production (EFF) are based onenergy statistics and cement production data, respectively, whileemissions from Land-Use Change (ELUC), mainly deforestation,are based on combined evidence from land-cover change data, fireactivity associated with deforestation, and models. The globalatmospheric CO2 concentration is measured directly and itsrate of growth (GATM) is computed from the annual changes inconcentration. The mean ocean CO2 sink (SOCEAN) isbased on observations from the 1990s, while the annual anomalies andtrends are estimated with ocean models. The variability inSOCEAN is evaluated with data products based on surveys ofocean CO2 measurements. The global residual terrestrialCO2 sink (SLAND) is estimated by the difference ofthe other terms of the global carbon budget and compared to results ofindependent Dynamic Global Vegetation Models forced by observed climate,CO2 and land cover change (some including nitrogen-carboninteractions). We compare the variability and mean land and ocean fluxesto estimates from three atmospheric inverse methods for three broadlatitude bands. All uncertainties are reported as ±1σ,reflecting the current capacity to characterise the annual estimates ofeach component of the global carbon budget. For the last decadeavailable (2004-2013), EFF was 8.9 ± 0.4 GtCyr-1, ELUC 0.9 ± 0.5 GtC yr-1,GATM 4.3 ± 0.1 GtC yr-1, SOCEAN2.6 ± 0.5 GtC yr-1, and SLAND 2.9 ±0.8 GtC yr-1. For year 2013 alone, EFF grew to 9.9± 0.5 GtC yr-1, 2.3% above 2012, contining the growthtrend in these emissions. ELUC was 0.9 ± 0.5 GtCyr-1, GATM was 5.4 ± 0.2 GtCyr-1, SOCEAN was 2.9 ± 0.5 GtCyr-1 and SLAND was 2.5 ± 0.9 GtCyr-1. GATM was high in 2013 reflecting a steadyincrease in EFF and smaller and opposite changes betweenSOCEAN and SLAND compared to the past decade(2004-2013). The global atmospheric CO2 concentration reached395.31 ± 0.10 ppm averaged over 2013. We estimate thatEFF will increase by 2.5% (1.3-3.5%) to 10.1 ± 0.6 GtCin 2014 (37.0 ± 2.2 GtCO2 yr-1), 65% aboveemissions in 1990, based on projections of World Gross Domestic Productand recent changes in the carbon intensity of the economy. From thisprojection of EFF and assumed constant ELUC for2014, cumulative emissions of CO2 will reach about 545± 55 GtC (2000 ± 200 GtCO2) for 1870-2014,about 75% from EFF and 25% from ELUC. This paperdocuments changes in the methods and datasets used in this new carbonbudget compared with previous publications of this living dataset (LeQuéré et al., 2013, 2014). All observations presented herecan be downloaded from the Carbon Dioxide Information Analysis Center(doi:10.3334/CDIAC/GCP_2014). Italic font highlights significant methodological changesand results compared to the Le Quéré et al. (2015)manuscript that accompanies the previous version of this living data.

Abstract

The Surface Ocean CO₂ Atlas (SOCAT, www.socat.info) is a synthesis activity by the international marine carbon community (>100 contributors) with support from SOLAS, IMBER, IOCCP, IOC and (inter-)national agencies. SOCAT brings together quality-controlled fCO₂ (fugacity of carbon dioxide) values for the global surface oceans and coastal seas with regular updates. Version 3 of SOCAT has 14.5 million surface water fCO₂ values for the years 1957 to 2014 with more than 1.0 million fCO₂ values per year for 2006 to 2012. SOCAT now accepts well-calibrated, good quality fCO₂ measurements from alternative sensors and platforms. Dataset flags reflect the accuracy of surface water fCO₂ values, ranging from better than 2 micro-atm (for the highest quality data) to better than 10 micro-atm (for alternative sensors). Automation of data upload is now enabling annual SOCAT releases from version 4 onwards. The interactive Data Set Viewer allows effective interrogation of the SOCAT data collection and rapid creation of high-quality figures for scientific presentations. Users of SOCAT data products are urged to acknowledge the contribution of data providers, as stated in the SOCAT Fair Data Use Statement. SOCAT version 4 is planned to be made public in early September 2016, and we'll highlight its updates above version 3 including observations to end of 2014. We will also present scientific applications of SOCAT including quantification of the ocean carbon sink and its long-term variation, detection of ocean acidification, as well as evaluation of coupled-climate and ocean-only biogeochemical models. SOCAT represents a milestone in coordinating international researchers, for the delivery of publically accessible and uniformly quality-controlled datasets, for marine and global carbon research and for informing government climate policy.
