Drone-Based Assessment of Marine Megafauna off Wave-Exposed Sandy Beaches
Remote Sensing, 2023 The wave-impacted waters off exposed sandy beaches support marine megafauna, including dolphins, whales, sharks, rays and turtles. To characterise variation in megafaunal assemblages in this challenging habitat, we used drone-based remote sensing to ...

Using Drone Footage to Analyze the Effect of Diver Presence on Juvenile Manta Ray Behavior
DronesManta ray tourism has become a multi-million-dollar industry proposed as a conservation tool in recent decades; however, its impacts remain unclear. We use drones and Markov models to quantify the effects of diver presence on a juvenile population of the

Cold-water coral reef frameworks, megafaunal communities and evidence for coral carbonate mounds on the Hatton Bank, north east Atlantic [PDF]
, 2008 Offshore banks and seamounts sustain diverse megafaunal communities, including framework reefs formed by cold-water corals. Few studies have quantified environmental effects on the alpha or beta diversity of these communities.

The importance of sample size in marine megafauna tagging studies [PDF]
Ecological Applications, 2019 AbstractTelemetry is a key, widely used tool to understand marine megafauna distribution, habitat use, behavior, and physiology; however, a critical question remains: “How many animals should be tracked to acquire meaningful data sets?” This question has wide‐ranging implications including considerations of statistical power, animal ethics, logistics ...

A new 3-D modelling method to extract subtransect dimensions from underwater videos [PDF]
, 2012 Underwater video transects have become a common tool for quantitative analysis of the seafloor. However a major difficulty remains in the accurate determination of the area surveyed as underwater navigation can be unreliable and image scaling does not ...

Understanding individual and population-level effects of plastic pollution on marine megafauna
Endangered Species Research, 2020 Plastic pollution is increasing rapidly throughout the world’s oceans and is considered a major threat to marine wildlife and ecosystems. Although known to cause lethal or sub-lethal effects to vulnerable marine megafauna, population-level impacts of ...

From sea monsters to charismatic megafauna: Changes in perception and use of large marine animals.
PLoS ONE, 2019 Marine megafauna has always elicited contrasting feelings. In the past, large marine animals were often depicted as fantastic mythological creatures and dangerous monsters, while also arousing human curiosity.
