This dataset contains data collected during the integration and demonstration of the newly developed SenseOCEAN multifunctional sensor package. The data were collected from field tests in Kiel Fjord (Germany), the Baltic Sea and the Mediterranean Sea in September 2016 and May 2017. New marine chemical sensors (such as optode sensors (O2, CO2, NH3, pH), lab on chip (LOC) sensors (NO3-, NO2-, PO43-, Fe2+, pH) and electrochemical sensors (silicate, N2O)), an integrated multifunctional sensor, plug and play Modbus module and data assembly centre were developed by the EU consortia, SenseOCEAN. The consortia consisted of TU Graz, Pyro Science GmbH, Chelsea Technology Group, Aarhus University, Alfred Wegener Institute (AWI), CNRS-LEGOS, Max Planck Institute, nke Instrumentation, TE Laboratories, University of Southampton, National Oceanography Centre (NOC), Unisense A/S and the British Oceanographic Data Centre (BODC). The sensors and Modbus module were deployed for demonstrations on various platforms including CTD Rosettes, fixed-position pontoons and NKE PROVOR profiling (ARGO) floats. The data were collected as part of the SenseOCEAN Collaborative Project funded by the European Union Seventh Framework Programme (FP7/2007–2013) under grant agreement No. 614141. The main aim of the SenseOCEAN project was to develop new chemical sensors for in situ measurements of the marine environment and to combine these to produce an integrated multifunctional biogeochemical sensor package. The coordinator was Professor Douglas Connelly at the National Oceanography Centre, Southampton, UK. The data are held by BODC as a series of ASCII data files conforming to the NASA AMES 1001 format together with a PDF document that describes the data set.

The Porcupine Abyssal Plain (PAP) Observatory is a sustained, multidisciplinary observatory. Key time-series datasets include measurements of sea temperature, air temperature, air pressure, waves, wind, CO2, salinity, Megafauna (Species diversity, abundance and biomass), geochemistry, humidity, chlorophyll, nitrate, PAR and currents. The PAP observatory is situated in the Northeast Atlantic away from the continental slope and mid Atlantic ridge (49N,16.5W, depth 4800m). Since 1989, this environmental study site in the Northeast Atlantic has become a major focus for international and interdisciplinary scientific research and monitoring including water column biogeochemistry, physics and benthic biology. Since 2002, a mooring has been in place with sensors taking a diverse set of biogeochemical and physical measurements of the upper 1000m of the water column. Some of these data are transmitted in near real-time via satellite. A diverse range of Essential Climate variables are measured and sampled at the PAP site from the atmosphere and surface ocean to the seafloor. The instruments used include CTD + Backscatter; ADCP (2 way, re-programmable for water profiling as well as burst sampling), Seismometer (2 way, retrieval of selected time period - 1 Minute - in the past e.g. seismic event), Bottom Pressure Sensor, Sediment trap (2 way, re-programmable for change sampling interval), Boxcores, Mega- and Multicores, Optode, Digital Camera and Stand-alone hydrophone. Seafloor sampling includes trawling, coring, towed camera systems from a research ship and time-lapse photography. Since 2002 many of the upper ocean measurements (0-1000m) have been transmitted in near real-time. There is a growing need for ever more accurate climatic models to predict future climate change and the impact this will have on human settlement, the insurance industry, fisheries, agriculture and nature at large. Long term observations at fixed points in the open oceans are essential to provide high quality and high resolution data to increase our knowledge of how our oceans function, how they are changing and how this may impact on the climate. The observatory is coordinated by the National Oceanography Centre. In 2010, a collaboration between NERC and UK Met Office has led to the first atmospheric measurements at the site.

The Christchurch Harbour Macronutrients Project is one of four consortium projects funded by the NERC through the Macronutrient Cycles Programme. The overall goal of the Macronutrients Programme is to quantify the scales (magnitude and spatial/temporal variation) of Nitrogen and Phosphorus fluxes and the nature of transformations through the catchment under a changing climate and a perturbed Carbon cycle. ‘The catchment’ is defined as covering exchanges between the atmospheric, terrestrial and aqueous environments, with the limit of the aqueous environment being marked by the seaward estuarine margin. The aim of the consortium research project is to better understand the behaviour of macronutrients over a range of temporal and spatial scales including the effect of storm events in the Hampshire Avon and Stour rivers and Christchurch Harbour estuary in Dorset. Data collection spans from October 2012 to January 2017. The Christchurch Harbour Macronutrients Project intensively monitored the river inputs and exchange of nutrients at the estuary mouth as well as looking at sediment re-suspension and the role of phytoplankton in macronutrient cycling within the estuary. By using a number of state of the art continuous monitoring techniques and modelling approaches, the scientists produced an accurate assessment of the impact of nutrients entering the estuary during short term storm increased flows in the two rivers. Previously, most water quality monitoring in rivers and estuaries has taken place at fixed times that are spaced too far apart to capture storms when they occur. This is the first project in the UK to intensively monitor water quality in estuaries using sensors and weather prediction technology to anticipate a storm. The Project PI is Duncan Purdie (Ocean and Earth Sciences, NOC).

The dataset comprises a wide range of physical and biogeochemical oceanographic and atmospheric parameters, plus additional biological measurements and observations. Hydrographic parameters include temperature, salinity, current velocities, fluorescence and attenuance, while biogeochemical and biological analyses of water samples provided measurements of dissolved gases, hydrocarbons, sulphur species, dissolved organic carbon (DOC), halocarbons, nutrients, pigments, bacteria, phytoplankton and zooplankton. Bird identification and cetacean abundance studies were also undertaken, as were tracer release experiments using both inert chemical (sulphur hexafluoride, SF6) and bacterial (Bacillus globigii) tracers. Meteorological data were also collected, including concentrations of various chemicals, supplemented by standard measurements of air temperature, pressure, irradiance, humidity and wind velocities. The data were collected in the North Atlantic Ocean and North Sea between 1996 and 1998, as follows: Eastern Atlantic off the coast of Ireland (June-July 1996 and May 1997); southern North Sea (October-November 1996); and North Eastern Atlantic between the UK and Iceland (June-July 1998). The data were collected during four cruises (RRS Challenger CH127, CH129, CH133 and RRS Discovery D234) using a variety of equipment, including instrumentation deployed at sampling stations (e.g. conductivity-temperature-depth (CTD) profilers) and underway sensors that ran throughout each cruise, yielding continuous measurements of both hydrographic and meteorological parameters. Discrete air and water samplers were also used to measure atmospheric and hydrographic parameters throughout each cruise. The data collection periods were associated with individual ACOSE air-sea exchange experiments: two Eastern Atlantic Experiments (EAE96 and EAE97); ASGAMAGE in the southern North Sea; and the North Atlantic Experiment, NAE. ACSOE was a 5-year UK NERC Thematic Research Programme investigating the chemistry of the lower atmosphere (0 - 12 km) over the oceans. The Marine Aerosol and Gas Exchange (MAGE) study group was the only component of the ACSOE Project that included measurements in the marine environment. ACSOE data management was a shared responsibility between the British Atmospheric Data Centre (BADC) and the British Oceanographic Data Centre (BODC). BODC handled the management of ship data as well as all other data collected in the water column during the ACSOE/MAGE cruises. BODC assisted in the onboard collection and subsequent working up of ship data, and assembled all marine data in BODC's relational database carrying out quality control and data processing as required. ACSOE was led by Prof. Stuart Penkett of the University of East Anglia and cruise principle scientists included representatives of the University of Newcastle Upon Tyne, and the University of East Anglia.

The dataset contains hydrographic and biogeochemical data, including continuous underway measurements of surface temperature, salinity, nutrients, chlorophyll and attenuance, irradiance and bathymetric depth. Underway dissolved oxygen and/or trace metal measurements were also collected on occasion. Hydrographic profiles of temperature, salinity, transmittance, fluorescence, dissolved oxygen (data often of poor quality) and scalar irradiance were undertaken, and associated water samples were routinely analysed for suspended particulate material (SPM), chlorophyll, nutrients and particulate organic carbon/particulate organic nitrogen (POC/PON). In addition, dissolved and particulate trace metals, production, contaminants, dissolved organic carbon/total dissolved nitrogen (DOC/TDN) were determined in some cases. Benthic measurements were also collected, including benthic flux determinations (microcosm experiments), sediment characterisation, pore water chemistry measurements and the quantification of the benthic macrofauna. The coastal oceanographic data set was collected along the east coast of England between Great Yarmouth and Berwick upon Tweed. Data were collected between December 1992 and July 1995 during a series of 17 RRS Challenger cruise legs. Most cruises covered two survey grids: one from Great Yarmouth to the Humber designed around the distribution of the sandbanks and a second simple zig-zag grid from the Humber to Berwick on Tweed. A large number of anchor stations, usually over one or two tidal cycles, were worked in the vicinity of the Humber mouth or the Holderness coast. Each cruise leg returned underway data and conductivity-temperature-depth (CTD) data and water bottle rosette samples from grid nodes. A Lasentech in-situ particle sizer was used to obtain grain size distributions at spot depths for each CTD station on many of the cruise legs. Box and multicorer samples were collected on approximately one third of the cruise legs. The River-Atmosphere-Coast Study (RACS) was the component of the Land Ocean Interaction Study (LOIS) programme looking at processes from the river catchment into the coastal sea. Investigators include representatives of Plymouth University, Southampton University, Liverpool University, University of East Anglia, Newcastle University, Plymouth Marine Laboratory, and the University of Wales, Bangor. All data sets collected during the RACS Challenger cruises are held by the British Oceanographic Data Centre (BODC). All underway and CTD data have been fully calibrated and quality controlled by BODC. The water sample and benthic data sets have been quality controlled by the data originators and submitted to BODC. The data are held in the BODC project database and have been published as part of a fully documented CD-ROM product.

The data set comprises measurement of physical and biological oceanographic parameters from the Western English Channel, initially collected as part of the Plankton Monitoring Programme at Station L4 from 1988 onwards. L4 is one of a series of hydrographic stations in the Western English Channel which have also been the basis of a series of hydrographic surveys carried out during the 20th Century by scientists at the Marine Biological Association in Plymouth. In May 2002 sampling expanded to include Station E1, approximately 25 nautical miles south-west of Plymouth. Plankton Monitoring began through the work of the Plymouth Marine Laboratory (PML) Zooplankton Group. Other stations include Rame head, Jennycliff, Plmouth Deep and Cawsand. A long-term time-series of weekly observations has been established by exploiting the activities of small boats (Sepia, Squilla and Plymouth Quest) in an opportunistic way as by-product of their other sampling activities, for example the collection of live plankton, sea-water, trawling for fish and squid. Initially no formal research programme or long-term funding for the Plankton Monitoring existed but the series was included in NERC Oceans 2025 funding as a Sustained Observatory and continues to be funded under NERC National Capability. Funding has been provided over different time periods under various names but the programme is commonly referred to as the Western Channel Observatory (WCO), with additional funding allowing additional data collection to take place, taking advantage of the core measurements. Although every attempt has been made to standardise methodology and achieve data consistency it is important to recognize that the varied personnel and research objectives that have contributed to this dataset may impact on the nature of the data set. The core datasets are made available through the westernchannelobservatory.org website. Data are also submitted to BODC where it is archived and published with a DOI at finer granules. At BODC further meta(data) checks take place and metadata are enriched and served through BODC systems with PML originators informed of any changes to data.

The UK Surface Ocean-Lower Atmosphere Study (UK SOLAS) marine fieldwork data set comprises all data, marine or otherwise, collected during sea-going activities. The fieldwork included eight dedicated research cruises in the eastern North Atlantic Ocean, spanning the period 2006-2008. These cross-disciplinary missions resulted in a diverse data catalogue. This includes meteorology (3-D wind speed and direction, total irradiance, Photosynthetically Active Radiation/PAR, air temperature, atmospheric pressure, humidity, aerosol optical thickness); atmospheric composition (carbon dioxide concentration, aerosol particle counts and size spectra, chemical analyses of aerosol particle composition, cloud condensation nuclei/CCN, concentrations of pollutants such as black carbon, concentrations of free radical species such as iodine monoxide and nitrate radicals); chemical and energy-fluxes across the air-sea boundary (dust deposition rates, oxygen and nitrogen fluxes, carbon dioxide fluxes, sensible heat fluxes, latent heat fluxes, momentum fluxes); biological, chemical and physical properties and processes in the sea surface micro-layer (chlorophyll concentration, bacterial production, phytoplankton and bacterial speciation, concentrations of biogenic trace compounds such as halocarbons, nitrous oxide, dimethyl sulphide/DMS and alcohols, surfactant concentrations, halogen concentrations such as iodine, iodide and iodate); biological, chemical and photochemical properties and processes in the ocean subsurface (primary productivity, trace gas production, plankton community composition, nutrient concentration, concentrations of trace metals such as iron, aluminium, manganese, magnesium and cobalt, ligand and complex metal chemistry parameters such as heme, dust dissolution, salinity, temperature, amino acids and urea, carbonate system chemistry including alkalinity); and sea-state physics (breaking waves, wave slope, whitecaps, bubble size spectra, aerosol formation, subsurface acoustics). Additionally, time series of air-sea fluxes were measured from the Norwegian weather ship, Polarfront, between 2006 and 2009. UK SOLAS scientists also participated in the Bergen Mesocosm experiment during 2008. This simulated gas exchanges and biological, chemical and photochemical properties and processes in the sea surface micro-layer under controlled conditions. The study united atmospheric and marine scientists from institutions across the UK and international collaborators. The UK SOLAS data set was intended to advance understanding of the mutual interactions between the atmosphere and the oceans, especially the chemical exchanges that affect ocean productivity, atmospheric composition and climate. It was funded by the UK Natural Environment Research Council, as the UK's contribution to the international Surface Ocean-Lower Atmosphere Study (SOLAS). The data are held at the British Oceanographic Data Centre (BODC) and have been incorporated into the National Oceanographic Database (NODB). Data collected from non-ship based activities, for example land-based atmospheric data and data resulting from campaigns using the Facility for Airborne Atmospheric Measurements (FAAM) aircraft are held at the British Atmospheric Data Centre (BADC).

The dataset comprises 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), biology (phytoplankton, zooplankton, primary production, community respiration, chlorophyll, pigments) and atmospheric particulates (major ions, organics and trace metals). Data have been collected from meridional transects of the Atlantic Ocean (between the UK and the Falkland Islands, South Africa or South America) from 1995 to the present day. The Atlantic Meridional Transect (AMT) programme aims to study the factors determining the ecological and biogeochemical variability of planktonic ecosystems in the tropical and temperate Atlantic Ocean, and their links to atmospheric processes. The majority of the data are available to academia for re-use and re-purpose but data from recent cruises may be subject to a moratorium which allows first use for data originators. The AMT is coordinated by Andy Rees (AMT Principal Investigator) and Miss Dawn Ashby (AMT Project Officer) at the Plymouth Marine Laboratory (PML) in conjunction with the National Oceanography Centre. Since its inception the programme has involved researchers from several different countries and has acted as a platform for national and international collaboration. Data are managed by the British Oceanographic Data Centre.
