SEACAMS (Sustainable Expansion of the Applied Coastal and Marine Sectors) is a research initiative linking academia and science
with Welsh businesses, funded by the Welsh Government and the EU. The SEACAMS Marine Mammal Ecology team has focused
on the needs of marine renewable energy (MRE) industries to meet regulatory requirements and fulfilling knowledge gaps by
providing assistance and advice on:
• Site characterisation for species diversity, abundance , distribution
and habitat use in proposed MRE sites
• Designing marine mammal surveys using visual and acoustic
techniques for both pinnipeds and cetaceans
• Trialling novel survey techniques for fixed vantage point surveys
• Conducting a feasibility study for an acoustic monitoring
programme for a proposed MRE site
• Collating and reviewing published marine mammal monitoring
guidelines for wave and tidal energy sites
• Developing novel ways to monitor cetaceans at high energy sites
using floating hydrophone arrays

localise animals

fixed vantage point surveys
The study was set up to trial the use of static acoustic data loggers
(C-PODs) at a high tidal range environment. This included
equipment calibration, site selection, mooring trials and initial data
analysis.
Biofouling of traditional
mooring gear of ropes and
surface markers
Acoustic release system without
surface markers reduces the risk
of entanglement and loss of gear
Trialling different types of mooring
gear and deployment methods to
find out most effective and practical
and safest way to collate static
acoustic monitoring data.

Frequency of acoustic encounters depicting
porpoise presence across the diel cycle
Harbour porpoise (Phocoena phocoena)
presence in an area is likely affected by
number of variables, including tidal, diel and
seasonal cycles. These graphs are results
from a pilot deployment, which will lead
into a more comprehensive study and
dataset which can be used to inform the
developer’s Adaptive Monitoring Plan.
