Tide pools to enhance marine life are being installed in the rock revetment at Long Curtain Moat in Portsmouth as part of the Southsea Coastal Scheme.
The 18 concrete pools are designed to create ecosystems that mimic natural rock pools found on rocky coastlines.
The pools retain water to increase the habitat diversity at all states of the tide, and the concrete material has a reduced pH to encourage colonisation by marine species.
It is expected that the marine life and flora and fauna to populate the tide pools will include seaweeds, barnacles, periwinkles and anemones.
Southsea Coastal Scheme environment enhancement lead Lucy Sheffield said the enhancements to the scheme will leave the coast better than when we started and demonstrate that this project is so much more than just a flood defence .
TSHD Sospan Dau back in Southsea December 22, 2020, by Zlatan Hrvacevic
Following a visit in November to form the eastern temporary platform, the TSHD Sospan Dau has returned to the Southsea coast.
The dredger will continue rainbowing material onto the foreshore, between Clarence Pier and the Spur Redoubt.
The dredged material will be levelled to complete the installation of the western temporary working platform.
VSBW, a VolkerStevin and Boskalis Westminster Ltd. joint venture, is the main contractor working to deliver the new sea defences as part of the Southsea Coastal Defence Scheme.
Stretching for 4.5km from Old Portsmouth to Eastney, the scheme will help to reduce the risk of flooding to more than 10,000 homes and 700 businesses.
