    The dataset comprises 74 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the Arctic Gateway area during August and September of 2008. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the National Oceanography Centre, Southampton as part of the Oceans 2025 programme.

    The dataset comprises the combination of estimates of anthropogenic carbon derived from hydrographic occupations of the 26N section with volume transports for the area between east USA and Africa calculated using the RAPID-MOCHA-WBTS AMOC timeseries. The data cover the time period between April 2004 and October 2012. The observations will be used with data from other sources to determine and interpret the accumulation of anthropogenic carbon in the North Atlantic, to infer the magnitude and variability of uptake of anthropogenic carbon dioxide from the atmosphere, and assess the risk of changes in the meridional overturning circulation on the marine carbon cycle. The Atlantic Biogeochemical Fluxes programme (ABC-Fluxes) is a joint effort between NERC in the UK (Principal Investigator Elaine McDonagh), and NOAA in the USA (Molly Baringer). It builds on the work of the RAPID-MOCHA-WBTS programme, a joint effort between NERC in the UK (Principal Investigator Eleanor Frajka-Williams), NOAA (Molly Baringer) and RSMAS (Bill Johns) in the USA. The Atlantic anthropogenic carbon transport (and its components), calculated from the above data, are held by BODC in NetCDF format.

    Seawater samples were collected from a series of ships of opportunity transiting between the UK and the Caribbean. Crossings occured almost monthly between May 2002 and October 2017. Roughly 90-100 samples were collected for each return journey from the ships' underway system and were frozen immediately for subsequent laboratory analysis. Nitrate, silicate, and phosphate levels were measured from these seawater samples. This work was funded by 5 different projects over the years - The Carbon variability studies by ships of opportunity (2000-2003), CARBOOCEAN FP6 (2001-2009), Carbochange (2011-2015), FixO3 (2013-2016), and NERC Greenhouse Gas most recently.

    This dataset contains hydrographic profiles (temperature, salinity, oxygen, fluorometer, transmissometer, irradiance) and along track measurements (bathymetry, surface meteorology, sea surface hydrography), with discrete measurements including water chemistry (organic and inorganic nutrients, particulate organic carbon and nitrogen, dissolved gases, trace metals) collected from a hydrographic section in the North Atlantic Ocean. This hydrographic section, designated A05 by the World Ocean Circulation Experiment (WOCE), runs along a nominal latitude of 24.5N between Florida and either Spain, North Africa, Portugal or the Canary Islands. Four UK cruises (D279, D346, DY040 and JC191) have contributed to this dataset to date using CTD casts, vessel-mounted and lowered ADCPs, bottle sampling and meteorological measuring systems to collect data. The measurements were collected as one of the UK's contributions to the Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) and with the aim of contributing to the study of decadal variability of the present ocean circulation and meridional transport of heat, freshwater and biogeochemistry, as part of the Climate Linked Atlantic Sector Science (CLASS) project. The work was led by teams from the National Oceanography Centre at Southampton. Data from the section are held at the British Oceanographic Data Centre (BODC).

    The dataset comprises 10 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, and 40 moored CTDs from across the North Atlantic Ocean area specifically the Subtropical North Atlantic, during May and June 2006. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the National Oceanography Centre, Southampton as part of the Rapid Climate Change Programme.

    The dataset comprises 117 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the South Atlantic Ocean area specifically a complete section from continent to continent from South America to Africa, during March and April of 2009. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the National Oceanography Centre, Southampton.

    This dataset contains particle flux analyses and current measurements collected from sediment traps and associated moored current meter instrumentation. Four McLane sediment traps were deployed in the Iceland Basin (by the Ocean Weather Station India) in a mesoscale array around 60 degrees N 20 degrees W to sample particle flux time series between November 2006 - July 2007 and August 2007 - June 2008. Sediment traps were deployed with Aanderaa RCM8 current meters 15 m below the traps, recording current speed and direction once an hour. The sediment traps were initially deployed during RRS Discovery cruise D312 and recovered on RRS Discovery cruise D321. For the second deployment period the traps were deployed on RRS Discovery cruise D321 and recovered on RRS Discovery cruise D340. The first sediment traps were prepared for analysis by scientists shortly after recovery. The second deployment samples were stored in the dark at 4 degrees Celsius until 2016 and were subsequently analysed. All sediment trap samples are preserved with formalin and hence should not be affected by long time storage. The samples were analysed for mass flux, particulate organic carbon (POC) and nitrogen (PON) flux, calcium carbonate flux, biogenic silica flux (including dissolved contribution for deployment 2), strontium flux (including Acantharian cyst fractions for deployment 1 and 2 and particulate fractions for deployment 2). The samples from the latter part of deployment 2 are thought to have severely under collected and so those data are flagged. The dataset was produced for the purposes of calculating sediment fluxes in the Iceland Basin and was funded by the Natural Environment Research Council (NERC) - Oceans 2025 Programme (Grant number NE/L002531/1).

    The dataset comprises 27 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, and 71 Moored CTDs from across the North Atlantic Ocean area specifically covering the Eastern Boundary and Mid-Atlantic Ridge areas during October and November of 2008. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the National Oceanography Centre, Southampton as part of the RAPID-WATCH (Rapid Climate Change - Will the Atlantic Thermohaline Circulation Halt?) programme.
