Abstract

Marine energy (MRE) developments often coincide with sites frequented by whales and dolphins. To understand habitat use and assess potential impact from development, echolocation clicks were recorded with acoustic click loggers (C-PODs) in Swansea Bay, Wales (UK). General Additive Models (GAMs) were...
