This dataset comprises physical, chemical and biological oceanographic measurements collected from the Mid-Atlantic Ridge as part of the UK’s ‘RidgeMix’ project between 2015 and 2016. Physical measurements include water column profiles of temperature, conductivity, current speed/direction and turbulence. These are supplemented by i) chemical samples targeting inorganic nutrients, oxygen and isotopes of radium/nitrate ii) biological samples to understand plankton distribution and to determine chlorophyll and enzyme concentrations. Samples were collected from the water column above the Mid-Atlantic Ridge, between latitudes of approximately 23 and 39 Degrees North. Sampling commenced in September 2015 with the deployment of moored sensors (thermistors, MicroCATs and ADCPs). This was followed up with a dedicated research cruise (JR15-007) between May and July 2016. During this cruise standard observational measurements were undertaken (including CTD, LADCP, SADCP and discrete water sampling), together with more specialised data collection activities (including deployment of turbulence profilers, standalone pumps, zooplankton nets, ocean gliders and a drifting wirewalker mooring). The cruise was also used to recover the moored instruments deployed the previous year. RidgeMix aims to investigate the mixing from internal tides over ridges and seamounts and the biogeochemical implications of this. The project is funded by a Responsive Mode grant from the UK’s Natural Environment Research Council (NERC) and runs from 2014 until 2019. RidgeMix is led by Professor Jonathan Sharples from the University of Liverpool, in collaboration with Principal Investigators from the National Oceanography Centre (Dr Matthew Palmer) and University of Southampton (Professor Alberto Naveira Garabato). This dataset collection brings together the observational component of RidgeMix. Users are advised to contact Principal Investigators for access to associated ocean modelling output from the project. Assembly of the observational dataset is still ongoing with BODC currently holding CTD and discrete sample data (chlorophyll and dissolved inorganic nutrients).

The dataset comprises 10 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the Indian Ocean area specifically the Crozet Islands, during December 2005 and January 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 University of Liverpool Department of Earth and Ocean Sciences as part of the CROZET (Benthic CROZet natural iron bloom EXport experiment) project.

This cruise dataset was collected during Prince Madog cruise PD33/08. Sampling of the water column comprised physical oceanography data (including salinity, currents, temperature, suspended particles) and biogeochemical data (including nutrient concentrations, dissolved gasses, pigment concentrations, fluoresence). Atmospheric data were also collected. Cruise PD33/08 sailed from Birkenhead on 22nd October, 2008 and docked on Birkenhead in 23rd October, 2008. During the cruise data was collected from sites situated in Liverpool Bay. This cruise was undertaken as part of the Oceans 2025 - Theme 10: Integration of Sustained Observations in the Marine Environment - Sustained Observation 11: Irish Sea Liverpool Bay observatory. Data has been provided to BODC by the University of Liverpool Department of Earth Sciences, the Proudman Oceanographic Laboratory, the Centre for Environment and Fisheries and Aquaculture Science Lowestoft Laboratory. The data are held by the British Oceanographic Data Centre. During this cruise the ship visited the following repeatedly sampled locations: COA (53.5252 N, -3.3834 S), Coastal Observatory Site 33 (53.4582 N, -3.9218 S), Coastal Observatory Site 21 (53.4522 N, -3.6413 S), Coastal Observatory Site 24 (53.4535 N, -3.7865 S), Coastal Observatory Site 10 (53.4556 N, -3.2344 S), Coastal Observatory Site 11 (53.4512 N, -3.37186 S) and Coastal Observatory Site 12 (53.4513 N, -3.505 S).
