Sharing of oceanographic data for long term ecological research of lter portofino site using ISTSOS (OGC)

The Italian Long Term Ecological Research Network (LTER-Italy) is a network of terrestrial, freshwater, transitional and marine waters, on which many-year ecological research is conducted. There are 25 sites (by 2015), distributed throughout the country, managed by the major research institutes, universities and institutions dealing with ecological research and monitoring in Italy. The ecological research carried out at the LTER Area Marina Protetta di Portofino (LTER-EU-IT-015) is aimed at continuing the study of the structure and dynamics of the main physical, chemical and biological variables along the water column, research on planktonic, benthonic communities and fish. Finally different studies are carried out on the role and impact of very important economic activities in the area such as fishing both professional and sporting. In accordance with the European Directives on the dissemination of data collection data (INSPIRE, Directive 2003/98/EC on the re-use of public sector information) and in order to provide support for achieving important environmental objectives as proposed by the Marine Strategy Framework Directive (MSFD), a geoservice for the dissemination of oceanographic data collected on LTER site has been provided. This geoservice has been developed on the basis of the Web Sensing Web Enablement (SWE) initiative through istSOS. Such application has allowed to create SOS services for multiple sampling and data collection systems usually used, in particular for fixed-point measures with thermistor. The implementation of the Standard Sensor Observation Service (SOS) and the information infrastructure, has permitted to manage in a simple, interoperable and efficient manner the observations from a network of monitoring stations equipped with DDR sensors for collecting oceanographic data, making the data searchable, accessible and fully reusable
