Environmental Report
Receptor Potential Data/ Information
Requirements
Potential Survey and/or Modelling
Requirements
ƒ Diver sampling;
ƒ Intertidal Phase 1 habitat mapping
techniques; and
ƒ Intertidal quadrat sampling.
Fish and shellfish ƒ Characterisation of abundance and
distribution of fish and shellfish.
ƒ Videos/photography surveys; and
ƒ Trawling surveys.
Ornithology ƒ Description of abundance and density of
foraging seabirds, passage and
overwintering waterbirds utilising coastal
habitat;
ƒ Impacts of noise on prey species of
birds.
ƒ Established seabird at sea and coastal
waterbird monitoring techniques;
ƒ Power analysis of the boat-based
seabird survey data;
ƒ Collision risk modelling;
ƒ OWF collision models and population
models; and
ƒ Habitat modelling.
Marine mammals ƒ Monitoring programme to understand
potential impacts, particularly of tidal
stream turbines.
ƒ Aerial surveys;
ƒ Land or boat based counts at haul-out
sites;
ƒ Vantage point surveys;
ƒ Boat based surveys;
ƒ Photo ID;
ƒ Telemetry;
ƒ Stranding and carcass ID;

ƒ Autonomous Acoustic Monitoring (e.g.
cetacean pods (C-PODs)).
Terrestrial ecology ƒ Characterisation of terrestrial ecology. ƒ Phase 1 habitat surveys covering the
terrestrial footprint of proposed works;
ƒ Phase 2 survey or key species listing
may be adequate in certain areas;
ƒ Bat potential and bat activity surveys;
ƒ Protected species surveys; and
ƒ Invasive species surveys.
Marine
archaeology
ƒ Characterisation of the marine
archaeological heritage and especially
the maritime archaeology (e.g. location
of protected wrecks).
ƒ Videoing of the seabed;
ƒ Multi-beam eco sounder survey
(surface) ;
ƒ Side-scan sonar survey (surface) ;
ƒ Seismic profiling (sub-surface);
ƒ Sediment coring (boreholes and
vibrocores);
ƒ Diver surveys/investigations; or
ƒ Radiocarbon dating.
Terrestrial
archaeology
ƒ SMR data; and
ƒ Presence of protected heritage,
including Scheduled Monuments and
Listed Buildings.
Cables, pipelines
and grid
connectivity
ƒ Proposed landfall sites of the tidal
device export cables in Alderney and
France;
ƒ Inter-array cable configuration; and
ƒ Existing terrestrial cable infrastructure.
Commercial and
recreational
fisheries
ƒ Up-to-date sea fisheries statistics for the
Bailiwick of Guernsey registered fleet,
and specifically the Alderney based fleet
(including fish landings data, fishing
