Marine Mammal and Acoustic Research


Scientists from LGL have expertise working with:

  • Cetaceans (whales, porpoises, dolphins)
  • Pinnipeds (seals, sea lions, walrus)
  • Polar bears

Objectives of projects can include:

  • Environmental impact assessments (U.S. NEPA compliance)
  • Incidental Harassment Authorization (IHA) and Letter of Authorization (LoA) applications for U.S. Marine Mammal Protection Act compliance
  • Literature reviews
  • Mitigation and monitoring of potential effects of development and disturbance
  • Seasonal distribution and abundance
  • Foraging ecology
  • Habitat use assessment
  • Photography and photo-identification / cataloguing

Specialized services:

  • Aerial, vessel, and shore-based surveys
  • Marine mammal observers
  • Measurements of underwater and in-air noise
  • Passive acoustic monitoring
  • Radio and satellite telemetry
  • Geographic information systems (GIS) and remote sensing
  • Environmental management and planning

For over 50 years, LGL has conducted marine mammal research and monitoring along the Atlantic, Pacific, Arctic, and Gulf of Mexico coasts of Canada and the U.S.A., as well as numerous projects overseas.


Marine Mammals & Noise
Marine Mammals and Noise book coverLGL and associates literally "wrote the book" on effects of noise on marine mammals. After years of studies of the effects of industrial disturbance on whales and other marine mammals in the Atlantic, Pacific, and Arctic oceans, LGL scientists compiled their information with collaborating partners to publish a comprehensive treatise on the subject (Marine Mammals and Noise, 1995, Academic Press).
