The Fluxes Across Sloping Topography of the North East Atlantic (FASTNEt) data set comprises a diverse collection of oceanographic (largely physical and chemical) observations, together with model simulation output. FASTNEt data were collected from three principal localities in close proximity to the UK’s Shelf Edge – the Celtic Sea, the Malin Shelf and the North Scotland Shelf. Each of these were chosen for contrasting bathymetric properties and associated slope current characteristics. There were two main research cruises associated with FASTNEt. These took place in the summers of 2012 and 2013. The core observations include measurements of temperature, salinity, nutrients, currents and shear harvested from a suite of instrumentation including CTDs, ocean gliders (as well as other Autonomous Underwater Vehicles), drifter buoys and moored sensors. The FASTNEt data set aims to develop new parameterisations of shelf edge exchange processes, which will benefit future ocean modelling and forecasting exercises. Additional observations were made from moored instrumentation and autonomous platforms (including ocean gliders, AUVs and drifter buoys) adding to the temporal and spatial coverage of the core cruise data sets. The FASTNEt data set was compiled in order to improve understanding of the processes of physical and biogeochemical exchange at shelf edge margins. These margins are important gateways for the supply of nutrients to our shallow shelf seas, with implications for biodiversity and fishery resources. The NERC FASTNEt Consortium brings together scientists from various UK research centres including the Scottish Association for Marine Science (SAMS), National Oceanography Centre (NOC) and the Universities of Bangor, Liverpool and Plymouth.

This multi-decadal time series initially contains water current and temperature data from a single, near bottom instrument. A second, shallower instrument recording the same parameters was subsequently added after several years of successful operation. Conductivity data are similarly integrated into the time series after a further period of operation. The data are typically at hourly resolution. The mooring is situated in the Tiree Passage, between the Isles of Mull and Coll, off the west coast of Scotland. The specific site chosen was where the passage is at its narrowest (10 km), mid-way between the coasts of the two Isles. The mooring site is in water depths of approximately 45 m. Mooring activity began in June 1981 and consisted of a single RCM current meter placed 11 m above the seabed. The mooring design was modified to incorporate a second RCM current meter at 22 m above the seabed from November 1987. Aanderaa conductivity sensors were added at the two depths in 1993, with MicroCAT conductivity sensors being incorporated in 2002. There are some gaps in the record, most noticeably between January 2000 and May 2002, a period when the observations were temporarily suspended. Fishing damage has generated smaller gaps in the data set over the years. This region was chosen as a site for long term monitoring after radiocaesium studies showed that the major part of the water carried northwards from the North Channel in the Scottish coastal current passes between Mull and Coll. The mooring provides data for comparison with tracer studies and for an examination of the roles of wind forcing and buoyancy contributions to the coastal current. Tiree Passage mooring work is led by Colin Griffiths at the Scottish Association for Marine Science (SAMS).

A database combining information on expertise and institutions, projects, conferences, and literature (i.e. information relevant to marine sciences: experts, institutions, datasets, publications, equipment), developed and maintained at the VMDC (VLIZ).

The data set comprises hydrographic and biogeochemical and biological measurements including temperature, salinity, currents, chlorophyll, dissolved organic and inorganic carbon and nitrogen, suspended matter concentrations, nutrients, plankton and fish. The results of primary production experiments are also included. The data were collected from the Bristol Channel, Severn Estuary, Celtic Sea and Plymouth Sound between 1971 and 1983. Measurements were taken over a series of more than 100 cruises, many with more than 50 stations. The most intensive sampling took place before 1975. The original data were collated and stored at Institute for Marine Environmental Research (IMER), which became Plymouth Marine Laboratory in 1988. As this is a large and important data set, which was previously held in an inaccessible format, it was selected for long-term archival at BODC as part of the NERC SEEDCORN programme. The data have been extracted, loaded into a relational database and are available on CD-ROM.

The Marine Environment Monitoring and Assessment National database (MERMAN) is a national database which holds and provides access to data collected under the Clean Safe Seas Environmental Monitoring Programme (CSEMP) formerly the National Marine Monitoring Programme (NMMP). The data collected are the responsibility of the Competent Monitoring Authorities (CMAs) who collect the samples from stations in UK waters using water sampling techniques, trawls, nets or grabs. The CMAs then send the collected samples to accredited laboratories where they are analysed. A weighting is calculated, based on the quality of the analysis. The weighting score incorporates the laboratory accreditation, reference material, inter-laboratory comparisons, detection limits, uncertainties and standard deviations. Where data do not meet a threshold score they are given a status of ‘FAIL’ and although they are stored they are not made available to external users. The contaminants and biological effects in biota data start in 1987 with greater use of the database occurring from 1997 onwards. Data are submitted by the CMAs annually and an annual submission may include updates to legacy data to provide additional data or improve data/metadata. The data held in MERMAN fulfils the UK's mandatory monitoring requirements under the Oslo and Paris Convention (OSPAR) Joint Assessments and Monitoring Programme (JAMP). These data are used in support of European Commission (EC) directives and national assessments, such as Charting Progress 2 and are also supplied to the European Marine Observation and Data Network (EMODNET).

Physical, bio-chemical and atmospheric data collected during the Mediterranean Forecasting Pilot Project MFSPP.

This dataset consists of measurements of underway meteorology, navigation and sea-surface hydrography collected aboard RRS James Cook cruise JC156, which ran between Southampton and Guadeloupe from 20 December 2017 to 01 February 2018. Navigation data were collected using an Applanix POSMV system and meteorology and sea-surface hydrography were collected using the NMF Surfmet system. Both systems were run through the duration of the cruise, excepting times for cleaning, entering and leaving port, and while alongside. This cruise formed the field component of NERC Discovery Science project 'FRidge: The impact of mid-Ocean Ridges on the Ocean's Iron Cycle'. The main objectives of the project were to: 1. Document the changes in iron supply, cycling and speciation along the diverse hydrothermal systems of the northern Mid-Atlantic Ridge. 2. Link observational science with state-of-the-art ocean modelling to assess the global influence of mid-ocean ridges on the ocean iron cycle and the sustenance of surface productivity. To deliver on these objectives, a research expedition to the Atlantic Ocean was carried out to measure trace metals, nutrients and ocean physics over and around the Mid-Atlantic Ridge. Ultimately, this will be able to address the broader question of how the amount of iron from mid-ocean ridges can influence phytoplankton growth in the open ocean. The Discovery Science project was composed of Standard Grant reference NE/N010396/1 as the lead grant with child grant NE/N009525/1. The lead grant ran from 04 September 2017 to 03 March 2020, and was led by Professor Maeve Lohan of University of Southampton, School of Ocean and Earth Sciences. The child grant ran from 01 August 2017 to 31 August 2020, and was led by Dr Alessandro Tagliabue. The data from this project will be a part of the UK contribution to the international GEOTRACES programme. Research takes place along the GEOTRACES International Section GA13. The underway discrete salinity samples data and the underway navigation, meteorology and sea-surface hydrography data have been received by BODC as raw files from the RRS James Cook, processed and quality controlled using in-house BODC procedures and are available online.

The data set contains wave measures from the surface images of the navigation radars located in the Spanish coast

Measurements of bathymetric data in Danish waters. The data are controlled and corrected to mean sea level before storage in hydrographic database.

The data are mainly used for map production.

The data set comprises time series measurements from offshore pressure gauges mounted on the sea floor. The data holdings are approximately 100 observation months from 30 sites. The data are mainly from trans-ocean sections in the North Atlantic. Data records contain date/time, total pressure (or relative pressure) and, occasionally, temperature. The sampling interval is typically 15 minutes or hourly, over deployment periods ranging from 1 to 6 months. Data were collected mainly by the Proudman Oceanographic Laboratory (POL), now the National Oceanography Centre (NOC) at Liverpool, and are managed by the British Oceanographic Data Centre (BODC).

These datasets consist of time series of shear probe data and data from other available sensors, used for estimates of the viscous rate of dissipation of turbulence kinetic energy. The datasets were put together as a part of the Scientific Committee on Oceanographic Research (SCOR) working group #160 "Analyzing ocean turbulence observations to quantify mixing" (ATOMIX), the shear probe subgroup prepared benchmark datasets. The datasets were collected from five sites: Baltic Sea (Leibniz Institute for Baltic Sea Research, Warnemünde, 20 September 2008), Faroe Bank Channel (University of Bergen, 10 June 2012), Minas Passage (Rockland Scientific International, 10 September 2016), Haro Straight (Rockland Scientific International, 19 October 2016) and Rockall Trough (Scripps Institution of Oceanography, July 2021). The datasets are presented in a documented and homogeneous format that encompasses four levels defined by the ATOMIX Working Group. The netCDF files include four hierarchical groups, corresponding to the four levels of microstructure data in the ATOMIX format: L1_converted: time series from all sensors converted into physical units; L2_cleaned: selected signals that are filtered and/or despiked before spectral analysis; L3_spectra: wavenumber spectra from shear probes and vibration sensors; L4_dissipation: dissipation estimates together with quality control parameters. These datasets provide a resource for users to evaluate their routines and allow for platform-independent analysis of shear probe data once the Level 1 data is provided. Users can then analyse data from their desired level, such as starting with Level 1, selecting sections of cleaned time series from Level 2, or utilising corrected shear spectra from Level 3.

The Inventory contains basic Turkish oceanographic metadata about data collected by 8 main Turkish institutes dealing with marine sciences. Inventory covers the period between 1960 and present. A web based user interface developed to easily handle and search the metadata.

This long-term project was designed to address issues raised by the previous ICES Overflow Expeditions. The project did not involve any joint actions in terms of synoptic coverage, the project being designed as a concerted action by its participants, especially in the area surrounding the Faroe Islands.

The Nansen project acquired 1305 station observations, of which 372 included chemical measurements. 6 countries (Denmark, Germany, Iceland, Netherlands, Norway, and the UK) contributed to the project.

Full details of shipborne observations, including information about the data held in this data set and elsewhere, is contained in the PC-based ICES ROSCOP database. The ROSCOP database can also be interrogated on-line via a web-interface.

The collection is made up of 130 species of ascidiaceans of the Iberian Peninsula from the intertidal area to 1,900 m. The sampling methodology used was direct collection at the intertidal area and autonomous divers and trawling off the coast, and the set contains information on sampling, date habitat, depth, measurements, colouring in 'vivo'. Drawings and photographs of 60 species are available.

A compilation by Marsden square of all high resolution CTD data held in the ICES database for the area 40-70N, 20W-40E. Data are available in ODV spreadsheet format.

The IMS-METU DNA barcodes dataset contains data on sequences of barcode genes (COI, ITS, RbcL and MatK) of mainly marine organisms from the Eastern Mediterranean, Aegean, Marmara and Black Sea and some other regions of the World Ocean. The DNA barcode data are supplemented with pictures of samples and sampling details. The DNA barcode data are periodically deposited to the Barcode of Life Data Systems BOLD (http://www.boldsystems.org/). BOLD is a web platform that provides an integrated environment for the assembly and use of DNA barcode data. It delivers an online database for the collection and management of specimen, distributional, and molecular data as well as analytical tools to support their validation. Since its launch in 2005, BOLD has been extended to provide a range of functionality including data organisation, validation, visualisation and publication. BOLD shares a tightly integrated data exchange pipeline with NCBI (GenBank). GenBank puts a default 1-year privacy period on records submitted through BOLD, where the records are deposited in GenBank but are still inaccessible to the public. This privacy period allows BOLD users to gain accessions early in the manuscript writing process and removes the need for rushing to gain accessions once the manuscript is in its final stages of acceptance by a journal. Then the data will be freely available. (http://www.boldsystems.org/index.php/resources/handbook?chapter=6_managingdata.html&section=publication).
