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...
Abstract. Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, terrestrial biosphere is important to better understand global cycle, support development climate policies, project future change. Here we describe data sets a methodology quantify all major components budget, including uncertainties, based on combination range data, algorithms, statistics, model estimates interpretation by broad scientific community. We discuss...
Abstract. Version 2 of the Global Ocean Data Analysis Project (GLODAPv2) data product is composed from 724 scientific cruises covering global ocean. It includes assembled during previous efforts GLODAPv1.1 (Global version 1.1) in 2004, CARINA (CARbon IN Atlantic) 2009/2010, and PACIFICA (PACIFic ocean Interior CArbon) 2013, as well an additional 168 cruises. for 12 core variables (salinity, oxygen, nitrate, silicate, phosphate, dissolved inorganic carbon, total alkalinity, pH, CFC-11,...
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 quality-controlled and internally consistent GLODAPv2 was used create global 1° × climatologies salinity, temperature, oxygen, nitrate, phosphate, silicate, total dissolved inorganic carbon (TCO2), alkalinity (TAlk), pH, CaCO3 saturation states using Data-Interpolating...
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. 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 water samples. This update GLODAPv2, v2.2019, adds data from 116 cruises the previous version, extending its coverage in time 2013 2017, while also adding some prior years. GLODAPv2.2019 includes measurements more than 1.1...
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 samples. GLODAPv2.2020 update the previous version, GLODAPv2.2019. major changes are data from 106 new cruises added, extension time coverage to 2019, inclusion available (also for historical cruises) discrete fugacity CO2...

The Global Ocean Data Analysis Project (GLODAP) is a synthesis effort providing regular compilations of surface-to-bottom ocean biogeochemical bottle data, with an emphasis on seawater inorganic carbon chemistry and related variables determined through chemical analysis samples. GLODAPv2.2022 update the previous version, GLODAPv2.2021 (Lauvset et al., 2021). major changes are as follows: data from 96 new cruises were added, coverage was extended until 2021, for first time we...
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 This contribution to the RECCAP2 (REgional Carbon Cycle Assessment and Processes) assessment analyzes processes that determine global ocean carbon sink, its trends variability over period 1985–2018, using a combination of models observation‐based products. The mean sea‐air CO 2 flux from 1985 2018 is −1.6 ± 0.2 PgC yr −1 based on an ensemble reconstructions history sea surface pCO (pCO products). Models indicate dominant component this net oceanic uptake anthropogenic , which...
Abstract The oceanic uptake and resulting storage of the anthropogenic CO 2 (C ant ) that humans have emitted into atmosphere moderates climate change. Yet our knowledge about how this has progressed in time remained limited. Here, we determine decadal trends C by applying eMLR(C*) regression method to ocean interior observations collected repeatedly since 1990s. We find global grew from 1994 2004 29 ± 3 Pg dec −1 2014 27 (±1σ). change second decade is 15 11% lower than one would expect...

During the Galicia X cruise, from May to October 1989 an intensive collection of hydrographic data was carried out at a single station on shelf off western coast Galicia. It allows us follow response water column intermittent equatorward wind stress during upwelling season. Upwelling events occur with biweekly periodicity, bringing Eastern North Atlantic Water (ENAW) subsurface layer our station. A trend thermohaline properties upwelled increase in time observed. This seems be mostly due...
Abstract. As a response to public demand for well-documented, quality controlled, publically available, global surface ocean carbon dioxide (CO2) data set, the international marine science community developed Surface Ocean CO2 Atlas (SOCAT). The first SOCAT product is collection of 6.3 million controlled from oceans and coastal seas, spanning four decades (1968–2007). gridded presented here second come project. Recognizing that some groups may have trouble working with millions measurements,...
The Global Ocean Ship-Based Hydrographic Investigations Program (GO-SHIP) provides a globally coordinated network and oversight of 55 sustained decadal repeat hydrographic reference (core) lines as part the global ocean/climate observing systems (GOOS/GCOS) for study physical oceanography, ocean carbon, oxygen nutrient cycles, marine biogeochemistry. GO-SHIP enables assessment sequestration heat changing circulation ventilation patterns, their effects on health Earth's climate. Rapid quality...
The Mediterranean Sea shows a peculiar anomaly in its nutrient pattern compared to the global ocean, as there is decrease concentration from west east. This feature has been attributed antiestuarine circulation at Strait of Gibraltar, where an eastward flow Atlantic nutrient‐poor surface waters compensated by westward countercurrent nutrient‐rich deep waters. water exchange suggested ultimate cause for oligotrophy basin, even though only few studies have accurately examined magnitude flux...
