These seabed and sea surface light data were collected in the Bay of Brest, Brittany, France, in 2011-2012. R.V. Albert Lucas and smaller vessels were used for deployment and recovery of the seabed light sensor instrumentation. Corresponding time series records of seabed and sea surface irradiance were collected. Water depth above, and water temperature at the position of the sensor were also recorded. The data were collected as part of a project studying the effect of tidal variations in water depth and clarity on the light that reaches the seabed (Roberts et al., 2014; Roberts, 2015). They were collected by Bangor University scientists (primarily E.M. Roberts), assisted by contacts at the Centre d'Etudes Techniques Maritimes et Fluviales (CETMEF, now Cerema) and the Institut Universitaire Europeen de al Mer (IUEM).

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.

The dataset comprises 6 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the Irish Sea and St. George's Channel, Bristol Channel and the Celtic Sea areas including specifically the Nymphe Bank and on the shelf edge in the vicinity of the Goban Spur. The data were collected during April of 1979. 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 Institute of Oceanographic Sciences Wormley Laboratory.

The UK Argo program is an active contributor to the international Argo program, offering a comprehensive data set vital for supporting global oceanographic research. The data set includes a mixture of near-real-time and delayed-mode data collected by profiling floats, quality controlled to operational ocean forecasting standards and to climate research standards respectively. Real-time data are available within 24 hours of the float surfacing, while delayed-mode data become available within 12 months of the profile date. UK Argo floats data are typically managed by the British Oceanographic Data Centre. Argo floats operate in profiling ‘cycles’, normally repeated every 10 days throughout their lifetime. As part of a cycle, floats drift at their parking depth of approximately 1000m for 5 or 10 days, then sink to 2000m before starting their ascent to the surface, taking temperature and conductivity measurements at regular intervals. Since 2012, biogeochemical sensors have gradually been rolled out across a portion of the UK Argo fleet, reflecting the broadening research focus of the international Argo program. The UK Argo data set now includes measurements of dissolved oxygen, chlorophyll fluorescence, optical backscatter, pH, nitrate and irradiance. Moreover, an array of Deep Argo floats have recently been adding observations as deep as 6000m, and deployments have ventured to higher latitudes. The UK Argo data set has a variety of uses, including assimilation into operational weather forecasts in near-real-time to climate and ocean biogeochemistry research with the delayed mode data. In addition to its national efforts, the British Oceanographic Data Centre manages floats deployed by partner nations including Mauritius, Saudi Arabia, Ireland, and Portugal. This collaboration underscores the cross-border cooperative nature of the program, which is fundamental to its world-wide success.

This dataset consists of measurements of various physical oceanographic parameters collected on a comprehensive survey of the Scotia Sea undertaken from 21 April and 22 May 2015. Data were collected on RRS James Clark Ross cruise JR311. 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. A CTD was launched at 24 stations throughout the cruise. Moving Vessel Profilers, Seasoar towed CTD, oceanloggers, temperature loggers and MSS turbulence profilers were all towed for multiple sections of the cruise. Multiple temperature-chain loggers were deployed at stations throughout the cruise. JR311 was the research cruise conducted as the observational element of the NERC Standard Grant, Surface Mixed Layer Evolution at Submesoscales (SMILES). The project aims to improve our understanding of submesoscale dynamics in regions characterised by strong fronts and where they impact on water mass transformation. For this reason, the field site was chosen to be the subantarctic front (SAF) to the east of Drake Passage where the Antarctic Circumpolar Current generates a pronounced front between the warmer subantarctic water to the north and the subpolar water to the south. To the north of the SAF, subantarctic mode water is formed through a process previously considered to be governed by air-sea interaction alone. SMILES aimed to investigate the extent to which submesoscale dynamics at the SAF and the surrounding region may impact on, and potentially govern, this process of water mass transformation. The Discovery Science project was led by Standard Grant reference NE/J009857/1, with child grants NE/J010472/1, NE/J010367/1 and NE/J008214/1. NE/J009857/1 was held at the University of Plymouth, School of Engineering, led by Dr. Phil Hosegood, running from 01 July 2014 to 31 December 2017. NE/J010472/1 was held at the University of Cambridge, School of Applied Maths and Theoretical Physics, led by Dr John Ryan Taylor, running from 01 April 2013 to 30 September 2016. NE/J010367/1 was held at the Plymouth Marine Laboratory, led by Dr Ricardo Torres, running from 01 June 2014 to 30 June 2017. Finally, NE/J008214/1 was held at the NERC British Antarctic Survey, led by Professor Michael Meredith, running from 01 July 2013 to 31 October 2016. All data have been received by BODC as raw files from the RRS James Cook to be processed and quality controlled using in-house BODC procedures and made available online. Data are available as raw files on request.
