Required Biological and Environmental Conditions

The objective of artificial seagrass is the development of suitable conditions for the restoration and growth of natural seagrass. This work package aims to determine the hydrodynamic and ecological characteristics that favour and support the growth of Zostera marina as well as their natural variation.

Dimensions for Artificial Seagrass

Observation of the environmental conditions on Work Package 3 provides a starting point towards the development of the Artificial Seagrass. Existing seagrass meadows in the area of interest are important sources of information regarding the environmental conditions needed for the seagrasses to grow and survive.

ASG Performance

In the first year, hydrodynamic as well as morphodynamic measurements will be conducted using a commercially available artificial seagrass which will be installed in the Large Wave Flume. At the end of the project phase all data from the project partners will be compiled to produce an artificial seagrass prototype.

SeaArt – Long term establishment of SEAgrass ecosystems through biodegradable ARTificial meadows

Diminishing seagrass meadows are difficult to re-establish because enhanced hydrodynamic energy and turbidity levels hinder resettlement. To improve restoration efforts, we develop artificial seagrass (ASG) that improves these environmental conditions so real seagrass can regrow. Obviously no potentially harmful non-degradable substances should be introduced into the system, so we will use fully biodegradable materials for our ASG.

To achieve our goal, scientists and industrial partners from different disciplines will work closely together. During the development of the ASG, they will also find answers to the following questions:

  • What are the demands of seagrass meadows on the environment?
  • How does seagrass influence the environment and on what does this influence depend?
  • Which forces does the natural or artificial seagrass need to withstand?
  • How do biodegradable synthetics decompose in seawater?
  • How can biodegradable products be made from fibres (e.g. from seagrass)?
