Environmental impacts of large-scale projects can be mitigated through careful planning and implementation of construction work. And access to high-quality, accurate environmental data is crucial.
For more than 10 years, the DHI team has been providing support to the Fehmarnbelt tunnel project. As the consortium leader of the Fehmarnbelt Environmental Monitoring and Consultancy (FEMO), DHI and partners have designed and carried out environmental impact assessments related to nature and water environments within the planned construction area. Some of these tasks include marine monitoring, sediment spill supervision and surveys, modelling and investigations related to hydrography, marine benthic flora and fauna, birds, marine mammals, coast and seabed conditions to ensure compliance with limits set by the authorities.
Femern A/S needed to make the above environmental data more accessible for all stakeholders. To fulfil this need, DHI developed the data portal ÆGIR to help Femern A/S publicly communicate, share and visualise the monitoring data and reports accompanying the environmental assessments. The data portal displays key environmental data, including:
- Monitoring data: such as data from flora, fauna and water surveys, marine birds and mammals monitoring, as well as sedimentation and metocean measurements
- Live data: for example, near real-time data from DHI’s extensive buoy system that measures hydrodynamic parameters, oxygen, temperature, turbidity, etc. throughout the Fehmarnbelt project area
- Conditional requirements: for instance, project-related sediment spill and airborne noise
