MARINE MAMMAL SCIENCE

MARINE MAMMAL SCIENCE:

WHAT WE DO:

ORCA Ireland's Marine Mammal Researchers

specialise in the study of marine mammal ecology, physiology and behaviour to enhance our understanding of marine mammal species population trends and habitat ranges through long-term monitoring efforts.

Photo Identification:

Non-Invasive Mark-Recapture Analysis


Photo identification using digital DSLR camera's is a marine mammal monitoring method commonly used around the globe, particularly for bottlenose dolphins and humpback whales. 


At ORCA IRELAND, our highly skilled field ecologists conduct opportunistic surveys of marine mammals on whale watching vessels and during dedicated photo identification surveys.  


At sea, ORCA IRELAND OBSERVERS systematically collect photographs of wild marine mammals. Using natural marking from the body, dorsal fin or by the trailing edge and patterns on whale flukes, individual animals can often be distinguished, which makes it possible to gather information on population abundance, individual movements, behaviour and social structure through mark-recapture techniques.

It's a Match! |  Photo I.D. Analysis
Images are processed post collection in the field so individual animals can be identified and catalogued. Cataloguing individuals and matching images of animals provides us with an opportunity to build observation histories and baseline data for studying life-history, social structure, behaviour, demographics and population dynamics.

UAV / Drone Surveys:

Unmanned Aerial Vehicles (UAVs) or "Drones" 

used in marine mammal research in Ireland was first pioneered by the ORCA IRELAND Team when professional drone photographer, Greg Coleman captured the first UAV footage of a whale in Irish waters in October 2018. A fin whale (Balaenoptera physalus), the second largest animal on Earth!



ORCA IRELAND's "birds-eye view" aerial monitoring with the use of novel monitoring tools i.e. UAV's or drones, which have become more accessible to researchers has advanced  our studies of marine mammals as drones are a safe, relatively inexpensive alternative to traditional boat-based photo-I.D. or aerial survey methods i.e. using manned aircrafts. 


However, there is a growing concern about the impacts of disturbance to marine mammals with the increasing accessibility of consumer grade drones. If you use drone to fly at sea, be sure to check out ORCA IRELAND's SeaSafe Best Practices Training Course to learn "Best Practice" should you encounter a marine mammal species with your drone.


ORCA IRELAND's marine mammal research has greatly advanced from the application of UAVs, providing more accurate information on species presence, abundance, morphometrics i.e. photogrammetry and behaviour. 


ORCA IRELAND has partnered with OCEAN ALLIANCE and SOUND SCIENCE on the "FLUKES FOLLOW PROJECT" to conduct specialised drone research on  whales that use Irish waters as a foraging habitat on their migratory journeys. ORCA Ireland also uses drones to help to monitor the health status of elusive species which otherwise would require invasive techniques like biopsy dart samples. ORCA Ireland's drone research is carried out under special permit from the National Parks & Wildlife Services (NPWS).


Members of the public who have captured drone footage of humpback whales or fin whales can assist the project by sending the footage to observersapp@gmail.com and logging their encounter through the Observers App.


Bioacoustics:

Static Acoustic Monitoring (SAM) & Passive Acoustic Monitoring (PAM)

cetacean research is carried out by ORCA IRELAND involves the detection, systematic classification and analysis of cetacean (porpoise, dolphin and whale) acoustic emissions in near-real time using sophisticated machine learning i.e. Artificial Intelligence (AI) Analytics.



ORCA IRELAND's innovative bioacoustics research uses machine learning for real-time cetacean acoustic monitoring in partnership with world renowned NGO Rainforest Connection (RFCx) and HUAWEI Ireland.
