Coastal Environmental Monitoring Coastal Environmental Monitoring StationStation
E.M.A.C.E.M.A.C. One of the key problems of the coastal marine environmental One of the key problems of the coastal marine environmental research is the lack of environmental information continuously to research is the lack of environmental information continuously to establish the conditions at each site and identify possible establish the conditions at each site and identify possible management programs and environmental management. management programs and environmental management. The Coastal Environmental Monitoring Station (EMAC) allows The Coastal Environmental Monitoring Station (EMAC) allows developed precisely to solve in an efficient and integrated these developed precisely to solve in an efficient and integrated these problems at a totally acceptable within the budget of public and problems at a totally acceptable within the budget of public and private bodies (municipalities, provinces, ports, marinas, etc.).., private bodies (municipalities, provinces, ports, marinas, etc.).., Research groups on these issues and environmental consultants. Research groups on these issues and environmental consultants. The heart of the system is a multifunctional datalogger which is The heart of the system is a multifunctional datalogger which is capable of accepting multiple sensors (9 simultaneously), which capable of accepting multiple sensors (9 simultaneously), which are shaped by their robust software.are shaped by their robust software.
