Data were collected in 2015, 2016 and 2017 to provide high resolution imagery for two sections of the South Saskatchewan River, Canada. Photographs were acquired using conventional aerial plane images with a 0.06m ground resolution, captured at a height of approximately 1500m from a fixed-wing aeroplane with an UltraCamXp sensor. Imagery was obtained on four occasions (13th May 2015; 2nd Sept 2016; 8th June 2017; and 12th June 2017). The dataset consists of eight orthomosaics; one for each of the two river sections on each of the four dates. Images were collected as part of NERC project NE/L00738X/1.

[This dataset is embargoed until March 31, 2024]. The data set contains multi-temporal aerial imagery for two river segments in the Philippines. Imagery covers: (i) the downstream segment of the Bislak River and (ii) the confluence of the Abuan, Bintacan and Pinacanauan de Ilagan Rivers (referred to as ‘Ilagan’ in this data resource). Repeat aerial surveys were completed in 2019 and 2020. The data coverage includes the river channels, floodplains and surrounding areas. Raw aerial images were processed to produce spatially corrected orthoimagery (see supporting documentation). The resulting orthoimagery has a 0.2 m spatial resolution, containing information on the red, green and blue (RGB) bands. The work was supported by the Natural Environment Research Council (NERC) and Department of Science and Technology - Philippine Council for Industry, Energy and Emerging Technology Research and Development (DOST-PCIEERD) – Newton Fund grant NE/S003312.

This dataset includes physical, biological and biogeochemical measurements of both the water column and seabed sediments. Hydrographic data include temperature, salinity, attenuance, dissolved oxygen, fluorescence, photosynthetically active radiation (PAR), sound velocity and current velocities, while biogeochemical analyses of water samples provided measurements of nutrients and biological sampling provided measurements of zooplankton abundance. A large number of benthic parameters were measured, including concentrations of substances such as nutrients, metals and carbon in both sediments and sediment pore waters. Benthic fauna were also studied, while rates of sedimentation flux were quantified. These oceanographic and benthic data were supplemented by satellite ocean colour imagery. The data were collected in the North Atlantic Ocean at the Mouth of Rockall Trough, Hatton-Rockall Basin and the Flank of Feni Drift between August 1997 and June 1999 over four cruises, comprising a preliminary site assessment (CD 107 August, 1997) followed by two process cruises (CD 111, April-May 1998, and CD 113, June-July 1998). A further cruise (CH 143) was part-funded by BENBO to retrieve moorings. The data were collected using a variety of instrumentation, including shipboard deployment of conductivity-temperature-depth (CTD) profilers with attached auxiliary sensors, benthic samplers, landers, cameras and incubation chambers, water samplers and continuous underway sensors. These were supplemented by moored sensor and satellite data. The BENBO programme was led by the Scottish Association for Marine Science/Dunstaffnage Marine Laboratory involved researchers from Southampton Oceanography Centre, Scottish Universities Research and Reactor Centre, Plymouth Marine Laboratory, Lancaster University, Leeds University, Edinburgh University, Cambridge University and the University of Wales, Bangor.
The dataset contains a diverse range of environmental data ranging from estuary properties including geomorphology, water depth and habitat characterisation to detailed time series of parameters such as salinity and chemical and nutrient concentrations. The data are stored in a database containing a directory of existing data sources for estuaries; data for the broad properties of 79 UK estuaries; and detailed hydrodynamic, bathymetric, and sedimentary information for six estuaries: Blackwater, Humber, Mersey, Ribble, Southampton Water and Tamar. The data range from 1965 to 2002 and include both historic datasets and those collected during a recent effort (1997-2002) to enhance our knowledge of estuaries. Data collection employed a variety of instrumentation and techniques, including water, biota and sediment sample collection and analysis and the deployment of hydrographic instruments such as sea level, temperature, salinity and optical backscatter recorders. The Estuaries Research Programme (ERP) began in 1997 with the EMPHASYS project, which aimed to improve our understanding of processes operating in estuaries and use this knowledge to enhance broad scale modelling techniques that can be applied to estuarine processes. This work was funded by the Environment Agency/Department for Environment, Food and Rural Affairs (DEFRA) Flood and Coastal Defence Research and Development Programme. The data are managed by the British Oceanographic Data Centre (BODC) and are available on CD-ROM.
The Marine Productivity (MarProd) programme data set comprises physical, biological and biogeochemical data, including hydrographic profiles (temperature, salinity, fluorescence, dissolved oxygen, photosynthetically active radiation (PAR)), and samples of nutrients, suspended particulate material, dissolved material, phytoplankton and zooplankton. These data were supplemented by continuous underway measurements of bathymetry, surface hydrography (temperature, salinity, fluorescence and attenuance), meteorology (wind speed and direction, PAR and total incident irradiance, air temperature, humidity and atmospheric pressure), remote sensing of sea surface temperature and ocean colour, and by production experiments. The data were collected in UK shelf seas and the North Atlantic Ocean between 2000 and 2002. Surface biogeochemical parameters (nutrients, photosynthesis, production, suspended particulate material and dissolved organic material) were measured during cruises in the Irish Sea in May, June and July 2001, while ongoing hydrographic and plankton time-series at Plymouth Marine Laboratory's L4 sampling station are also included in the data set. However, the bulk of the data were collected during a major fieldwork campaign of four dedicated research cruises on RRS Discovery between November 2001 and December 2002. A total of over 800 gear deployments were performed at 159 stations mainly distributed in the Irminger Sea and Iceland Basin, facilitating the measurement of water mass distribution, velocity field and mixed layer properties. A comprehensive water sampling programme was undertaken for the purposes of plant pigment and microscopic analyses; biomass estimations of different taxonomic/functional groups of microplankton (picoplankton, phytoplankton and microzooplankton); high resolution profiles of inorganic nutrient concentrations; and determination of abundance of key zooplankton species (Calanus finmarchicus, Oithona spp. and euphausiids). Process studies were undertaken to obtain information about factors controlling the reproduction, growth, mortality and behaviour of individual species using physiological studies (feeding experiments, egg production and nauplii development, species interactions) and analyses of biochemical composition (lipids and hormones studies, analyses of carbon/nitrogen and stable isotope ratios composition). Phytoplankton primary production was measured using carbon uptake on the last two cruises and additional data were collected using a Fast Repetition Rate Fluorometer (FRRF) through continuous surface underway sampling and vertical deployments. MarProd's main objective was to investigate the population dynamics of key zooplankton species in UK shelf seas and in the northern Atlantic with emphasis on the manner in which physical factors such as water temperature and oceanic currents influence their distribution, abundance and productivity. The MarProd Programme involved researchers from numerous institutions from the UK, Ireland and Spain. The data are archived at the British Oceanographic Data Centre.
