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).

This dataset comprises of hydrographic data from the Thwaites-Amundsen Regional Survey and Network (TARSAN) Integrating Atmosphere-Ice-Ocean Processes affecting the Sub-Ice-Shelf Environment project. CTD and glider data have been collected across a number of RV/IB Nathaniel B Palmer cruises in the Amundsen Sea during austral summer since 2018. The CTD data include conductivity (salinity), temperature and depth alongside auxiliary data including oxygen, fluorescence, transmission and PAR. Seagliders collected CTD, oxygen, fluorescence, PAR and microstructure data. The CTD data support data collected by gliders, ship-based surveys and autonomous underwater vehicles (AUVs). The data were collected to help identify how variations in oceanic conditions may influence the behaviour and stability of ice shelves in the region. The data were collected under the NERC grant NE/S006591/1 and in collaboration with the National Science Foundation in the United States.

This dataset contains physical oceanographic data, comprising acoustic doppler current profiler (ADCP) and waverider measurements. The ADCP data were collected using a Teledyne RDI Workhorse Sentinel-600 ADCP mounted on a seabed frame at the European Marine Energy Centre (EMEC) full scale tidal test site at Fall of Warness, Orkney - UK. No structures were present around the instrument at the time of the deployment. Data were collected over a two week period between February and March 2005, with a sampling resolution of 20 minutes. Data were processed by the originator using the company’s in-house Integrated Metocean Processing, Analysis and Quality Control Tool (IMPAQCT) software. Data comprise current speed profile (with on average 40-50 bins), current direction profile (vertical bins), echo amplitude (four beams), percentage good pressure and beam solution, pitch, roll, heading, and water temperature. The waverider data were collected using a Datawell Waverider buoy moored at the southern part of the full-scale wave test site at Billia Croo, Orkney. Data were collected over a one year period in 2017, with a sampling resolution of 30 minutes. Data were processed using the Datawell W@ves21 software. Data comprise wave spectral parameters, including significant wave height, spectra peak period, wave direction at the peak frequency, directional spread at the peak frequency, zero-upcrossing period (from spectra), and mean period (T01). Data were collected by the EMEC as part of research focusing on wave and tidal power development.

This dataset consists of measurements of water column structure including hydrographic profiles, temperature and salinity, turbulence data, turbidity and fluorescence profiles, current velocities and sound velocities. The measurements were undertaken during a comprehensive survey of the southern Celtic Sea between May and August 2012. Some turbulence microstructure data were collected from the 14th to the 24th of May 2012, while the remaining data were collected from the 10th to the 22nd of August 2012, aboard the RV Falcon Spirit. These cruises formed the field component of NERC Discovery Science project "Assessing the sensitivity of marginally stratified shelf seas within a changing climate". The data were collected in order to identify processes involved in the existence and intensity of the front displays not governed by tidal periodicities, to test whether the processes identified as important to changes in shelf sea stratification through in-situ measurements are indeed responsible for observed changes and to incorporate new knowledge into state-of-the-art numerical models that can upscale the processes observed within this project to the shelf sea environment. The Discovery Science project was composed of Standard Grant reference NE/I001832/1. The project ran from 01 January 2011 to 30 June 2014. Dr Philip Hosegood of University of Plymouth School of Marine Science and Engineering was the principal investigator of this project. The moored temperature logger data have been received by BODC as raw files from the RV Falcon Spirit, processed and quality controlled using in-house BODC procedures and can be downloaded online from the BODC website in a variety of data formats including ASCII, ODV and NetCDF. Full documentation on the dataset is supplied on download. Raw file versions of the minibat towed undulator transect data, moored ADCP data, VMADCP data and turbulence microstructure data are available on request.

This dataset includes high-definition video imagery, hydrographic and navigation data from the Isis remotely operated vehicle (ROV). These data were then used to perform a biometric and reproductive analysis on Kiwa tyleri sp. which also forms part of the dataset. Four hydrothermal vent and cold seep sites were sampled during thirty one ROV dives: south of Bird Island on the South Georgia shelf, the E2 and E9 segments of the East Scotia Ridge, and the Kemp Seamount. The dives were undertaken between 10th January 2010 and 12th February 2010 during the RRS James Cook research cruise JC042 (7th January - 24th February 2010). The Isis ROV was equipped with a high-definition video camera, a CTD package, an Ultra Short Baseline navigation system and a suction sampler. The data were produced as part of the NERC Consortium Grant project Chemosynthetic Ecosystems in the Southern Ocean (ChEsSo), which funded a total of four cruises (JR224, JC042, JC055 and JC080). The dataset contributed to the project aims to search for, identify and intensively study hydrothermal vent and cold seep sites in the eastern Scotia Sea. The existing dataset was produced by scientists from the University of Southampton and technicians from the National Oceanography Centre. Additional data for these cruises may become available in the future. Please note that the access restrictions for video imagery, hydrographic and navigation data are currently unknown. The biometric and reproductive analysis data are unrestricted and accessible through the Published Data Library.

This dataset consists of measurements of underway meteorology, navigation and sea surface hydrography as well as underway discrete salinity samples. A comprehensive survey of the Tropical Atlantic was undertaken between June and August 2017. Data were collected on RRS James Cook cruise JC150. 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. 65 salinity samples were taken from the non-toxic underway supply. The non-toxic, pumped seawater supply intake was located 5.5 m below the sea surface. Sample analysis was completed using a Guildline 'Autosal' salinometer. This cruise formed the field component of NERC Discovery Science project "Zinc, Iron and Phosphorus co-Limitation in the Ocean (ZIPLOc)". The data were collected in order to determine the prevalence of zinc and iron limitation of APA in the phosphate deplete subtropical North Atlantic Ocean; to quantify the impact of zinc-phosphorous and iron-phosphorous co-limitation on biological activity, specifically phytoplankton growth, primary production and nitrogen fixation; and to quantify the significance of zinc-phosphorous and iron-phosphorous co-limitation in driving phytoplankton productivity over basin scales and multi-decadal time scales. The Discovery Science project was composed of Standard Grant reference NE/N001079/1 as the lead grant with child grant NE/N001125/1. The lead grant ran from 02 January 2017 to 03 February 2017 and the child grant ran from 01 February 2017 to 31 July 2019. Dr Claire Mahaffey of University of Liverpool, Earth, Ocean and Ecological Sciences was the principal investigator of the lead grant of this project. Prof Maeve C. Lohan of University of Southampton, School of Ocean and Earth Science was the principal investigator of the child grant. 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 will be made available online in the near future.

This dataset consists of underway meteorology, navigation and sea surface hydrography measurements from cruise JC044 and JC082 as well as 7 CTD casts for cruise JC082. Data were collected on two RRS James Cook cruises, JC044 and JC082, covering the Cayman Trough and Mid-Cayman Spreading Centre in the Caribbean Sea. Cruise JC044 took place between March 25th and April 22nd 2010 and cruise JC082 took place between February 6th and March 8th 2013. 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. CTD data were obtained from a Seabird SBE CTD system fitted to a rosette and launched at stations along the cruise track. Data were collected as part of the NERC-funded project “Hydrothermal activity and deep-ocean biology of the Mid-Cayman Rise” which aimed to investigate the world's deepest under-sea volcanic ridge, the Mid-Cayman Rise, to advance understanding of patterns of biodiversity in the planet's largest ecosystem. By studying the geology and hydrography of the world's deepest seafloor spreading centre using established techniques, the project aimed to confirm the geological processes driving the vents and to reveal the evolutionary genetic relationships of their inhabitants to those in vents elsewhere. The project was funded by two NERC standard grants. The lead grant, NE/F017774/1, ran from 15 September 2009 to 01 March 2014, and was led by principal investigator Dr Jonathan TP Copley of University of Southampton, School of Ocean and Earth Sciences. The child grant, NE/F017758/1, ran from 19 July 2009 to 31 December 2013, and was led by Dr BJ Morton of National Oceanography Centre, Science and Technology. Underway navigation, meteorology and sea surface hydrography and CTD datasets have been received as raw files by BODC and are available upon request.

This dataset includes measurements made by pressure, temperature, conductivity, backscatter, oxygen, photosynthetically available radiation (PAR) and chlorophyll fluorescence sensors attached to two Seagliders deployed in the Western Ross Sea, Antarctica (-77.420 degrees S and 176.139 degrees E). The gliders produced profiles roughly every 2 hours from the sea surface to the seabed (about 800 m depth) and all observations are un-gridded timeseries. Seaglider 676 (sg676) was deployed on 28 November 2022 and Seaglider 613 (sg613) was deployed on 04 December 2022, both from the fast ice. Both Seagliders were recovered on 18 January 2023 by the R/V Nathaniel B. Palmer (Cruise number NBP23-02). Each glider dataset was processed using the UEA Seaglider toolbox (available at: http://bitbucket.org/bastienqueste/uea-seaglider-toolbox). The campaign was designed to provide the biophysical conditions to link with the Adelie penguin preyscape. The campaign also sampled the extensive eddy field in the region, and obtained observational data in a key region of very high biological productivity (i.e. the Ross Sea polynya). The Discovery Science project is funded by the Natural Environmental Research Council, UK (NERC) and the National Science Foundation, USA (NSF) (grant reference NE/W00755X/1).

The dataset comprises 125 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during September - October 1999 in the North East Atlantic Ocean between Iceland and Scotland 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 Southampton Oceanography Centre.
