Physical and biogeochemical data from three Seagliders on a combination transect and virtual mooring deployment, NE of Barbados 2020
A dataset collected by investigators of the University of East Anglia during January - February 2020 in the tropical North Atlantic. Gliders SG620 and SG637 were deployed from the RV Meteor during cruise M161 as part of the EUREC4A oberservational campaign. Glider SG579 was deployed by the autonomous surface vehicle Caravela. All gliders were recovered by the Meteor. SG620 and SG637 occupied a bowtie pattern 10 km across centered at 14'10''N 57'20''W. The two gliders were deployed with CT sails measuring conductivity and temperature and completed 131 and 155 dives respectively. SG579 was deployed at 13'21''N 58'50''W and travelled 200 km to the bowtie over 10 days conducting 75 dives. Once onsite, SG579 conducted a further 220 dives. In addition to a CT sail, SG579 carried a PAR sensor and Wetlabs sensor measuring backscatter, chlorophyll a and CDOM. Data were processed using the UEA Seaglider Toolbox.
Temperature-depth profiles from dive computers, underwater cameras and Castaway microCTDs, collected during sea and hyperbaric chamber dives in Scotland (2020).
A collection of raw water temperature-depth-time profiles were recorded from a selection of dive computers, underwater cameras and baseline Castaway microCTD devices. Data were collected at Oban recompression chamber (owned and managed by Tritonia Scientific), as well as during sea dives local to 56.42 N, 5.47W, over a two-week period between 08/01/2020 and 07/02/2020. A number of different devices and models were tested during the study. Chamber dives were undertaken to test and compare device response time (29 devices over 11 dives) and accuracy (6 replicate dives). This was followed by local sea dives to further compare device accuracy. During each pair of sea dives (6 total), half of the devices were mounted on a frame with the remainder worn by two divers. For the subsequent dives in each pair, each device was switched to the alternate mounting position. Dive profiles were exported from individual dive computers into Subsurface open source software, then exported in ssrf (XML) format for each week of data collection. Profiles from all dive computers were combined for analysis. Castaway microCTDs and Paralenz Dive Camera+ profiles were exported as individual CSV files per dive. Data were collected as part of Celia Marlowe’s PhD project at the University of East Anglia, which aimed to assess the precision, accuracy and uncertainty in water temperature profiles collected from devices commonly carried by Scuba divers. The PhD project is part of the Next Generation Unmanned Systems Science (NEXUSS) Centre for Doctoral Training, funded by the Natural Environment Research Council (NERC) and the Engineering and Physical Science Research Council (EPSRC) (NE/N012070/1), and is additionally supported by Cefas Seedcorn (DP901D). The diving and chamber tests were supported through a NERC National Facility for Scientific Diving grant (NFSD/17/02).
Remineralisation of organic carbon by marine bacterioplankton (REMAIN) project oceanographic and eykariotic plankton respiration datasets (2017-2020)
This dataset is comprised of laboratory based culture experiments with five eukaryotic plankton species. The plankton were grown in culture media made up in filtered seawater collected from the continuous seawater supply system in the laboratories of the Centre for Environment Fisheries and Aquaculture Science (Cefas) in Lowesoft, UK, pumped from the North Sea. Experiments were undertaken between December 2017 and March 2019. The dataset also includes environmental data: dissolved oxygen concentration from water samples collected from CTD casts on the AMT28 cruise which took place from September 23 to October 30, 2018. This study contributes to the ‘Marine bacterioplankton respiration: a critical unknown in global carbon budgets’ project funded by The Leverhulme Trust (RPG-2017-089) and the ‘Remineralisation of organic carbon by marine bacterioplankton (REMAIN)’ project funded by NERC Discovery Science (grant reference NE/R000956/1 active from December 01, 2017 to November 30, 2020). Data were generated by Carol Robinson, Isabel Seguro, and E. Elena Garcia-Martin of the University of East Anglia.
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).
This dataset consists of observations from two autonomous underwater gliders deployed by the University of East Anglia, UK and Sultan Qaboos University, Oman. The two Seagliders, Humpback serial number SG579 and Orca serial number SG510, collected data to investigate physical-biological interactions in the water column. The gliders were deployed in the Gulf of Oman approximately 10 km from Muscat, at the 120 m isobath. Both gliders repeatedly surveyed a 76 km section across the shelf, continental slope and open ocean between 24°15’ N, 59° E and 23°39.5’ N, 58°39’ E. Humpback, SG579 obtained 1,424 vertical profiles over a 91 day period (4 March 2015 to 3 June 2015), repeating the section 24 times. Orca, SG510 obtained 1,646 vertical profiles over a 109 day period (9 December 2015 to 27 March 2016), repeating the section 28 times. The glider data were processed using the UEA Seaglider Toolbox and standard techniques were used for calibration of the data. The data are held at BODC as a series of netCDF, .eng and .log files alongside a .mat file containing all processed data.
This dataset consists of near real-time ocean observations from an autonomous underwater glider, sampling at the Joint North Sea Information System (JONSIS) hydrographic section (2.23°W to 0° at 59.28°N) between 12th October and 2nd December 2013. The measurements were made by a Seaglider (serial number 502) and consist of full-depth temperature, salinity, oxygen, chlorophyll and optical backscatter observations. Dive-average current observations were also collected. This dataset contains standard raw NetCDF (.nc), engineering (.eng) and log (.log) files captured using Seaglider base station version V2.05. The glider deployment was a collaborative effort between the University of East Anglia (UEA) and Marine Scotland Science. Deployment took place from Research Ship MRV Scotia, whilst recovery utilised MPV Jura. The JONSIS repeat section crosses the path of the Fair Isle Current and the East Shetland Atlantic Inflows, key routes by which Atlantic water enters the northern North Sea.
