MARINE MEGAFAUNA PELAGIC SURVEY
Silver Bank to Punta Cana, Dominican Republic
The primary goal of this expedition is to collect extensive data on sperm whales, humpback whales, and other cetaceans, utilising both visual and acoustic detection methods. Environmental DNA (eDNA) tools will also be employed to enhance research efforts in this critical region. The survey will contribute to establishing a biodiversity baseline, enabling the Ministry of Environment to support informed conservation strategies. The Ministry of Environment and Natural Resources will ensure efficient issuance of all necessary permits, adhering to national regulations and conservation goals.
Survey Methods
Marine Mammal and Seabird Surveys
Acoustic Detection:Visual surveys will run from 6:00 AM to 6:00 PM, while acoustic monitoring will take place from 6:00 PM to 6:00 AM.
Data Recording: Photo ID Observations will include species presence, group size, behaviour, environmental conditions, marine traffic, and vocalisations.
eDNA Collection: Sample Collection
Water samples will be collected twice daily, prior to BRUV (Baited Remote Underwater Video) deployment. Samples will be collected at varying depths using sterile containers, with precise GPS coordinates recorded for each sample.
Analysis Goals: To identify species presence and abundance, detect invasive species, and assess ecosystem complexity.
BRUV (Baited Remote Underwater Video)
Deployment: BRUV systems will be deployed during the first and last hour of daylight to capture footage of marine species attracted to bait. This method will provide data on species diversity, distribution, and abundance.
