    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.
