In collaboration with the University of Plymouth, ARC Marine has constructed and deployed 5 intertidal BIO Blocks between the National Marine Aquarium and the University’s Marine Station within Plymouth Harbour. The BIO Blocks are 1m x 1m solid concrete cubes with various holes and depressions formed into the cube itself to replicate a rocky intertidal area complete with rock pools and other topographical niches. The BIO Blocks each weigh approximately 2.4 tonnes each and they were developed by Dr Louise Firth from the University of Plymouth. These blocks will be left in situ for 24 months and monitored by students from the university for their effectiveness as a tool aiding the replenishment of marine life. During the monitoring period the species growing on the cubes will be identified and their abundance noted. Their location will also be mapped on the blocks for their preferred areas and which of the various holes and depressions are proving most effective. In the area where the blocks are located, we expect that the growth will be dominated by various seaweed and kelp species because of the high light availability, rocky substrata and close proximity to an already established kelp bed. As well as the seaweed and kelp growth we expect to see various types of crab, anemones and sponges just to name a few! We will keep you updated on their development as time progresses!
