An Alternative Framework to Assess Marine Ecosystem Functioning in Shelf Seas (AlterEco) will utilise a small fleet of submarine and surface autonomous vehicles combined with ongoing observational programmes to capture a seasonal cycle of physical, chemical and biological measurements on repeat transects over ~150km in the North Sea between November 2017 and January 2019. This dataset contains near real-time hydrographic measurements through the water column obtained from submarine Slocum gliders and Seagliders. The submarine vehicles have also been equipped with auxiliary sensors such as turbulence probes, nutrient sensors and acoustic sensors. Data from these platforms will be converted into the international 'Everyone's Gliding Observatories (EGO)' exchange format. This dataset will also contain measurements taken from CTDs deployed on eight cruises to provide calibration data for the autonomous vehicles. AlterEco involves collaboration between scientists at a number of organisations (National Oceanography Centre (NOC, lead), University of East Anglia (UEA), University of Liverpool (UoL), Plymouth Marine Laboratory (PML), Scottish Association for Marine Science (SAMS) and the Centre for Environment, Fisheries and Aquaculture Science (Cefas). In addition, there are a number of UK and international project partners.
