RM6187: Lot 9 - Marine Mammal Surveys V2

The Liverpool City Region Combined Authority (LCRCA) is progressing consideration of a wide range of energy and infrastructure plans as part of Net Zero 2040, one of which is a tidal range power project, one of which is the Mersey Tidal Power Project (MTPP). The MTPP is currently at Phase 4A pre-scoping stage with geographical potential being explored and review of location constraints for two reference cases, a potential barrage across the River Mersey and / or a potential lagoon in Liverpool Bay. As part of initial pre-scoping studies, the MTPP intends to gain a better under-standing of marine mammals species presence, abundance and habitat use in the Mersey and adjacent areas. A robust baseline is necessary for DCO and regulatory assessments with considerations including structure passage and potential changes in water quality and hydrodynamic conditions.
