Acoustic evidence for topographic blocking on a steep submarine canyon wall
Abstract Diel vertical migration (DVM) is the largest mass‐movement of animals on Earth, with profound ecological and biogeochemical consequences. DVM has mostly been studied in the open ocean; however, at steep slopes, pelagic animals including vertical migrators must contend with the seafloor, emphasizing the importance of understanding DVM in these ...

To better understand spatiotemporal variation in the trophic structure of deep-pelagic species, we examined the isotope values of particulate organic matter (POM) (isotopic baseline) and seven deep-pelagic fishes with similar diet compositions but ...

Persistent Enhancement of Micronekton Backscatter at the Summits of Seamounts in the Azores [PDF]
Knowledge of the dynamics of micronekton at seamounts is critical to understanding the ecological role of these ecosystems. Active acoustic techniques are an effective tool to monitor the distribution and movements of pelagic organisms. We carried out several day- and nighttime active acoustic surveys over a 3-year period (2009–2011) to characterize ...

Micronekton are a key component of the pelagic food web of the Chatham Rise east of New Zealand. The Chatham Rise is an important fishing area for hoki (Macruronus novaezelandiae), New Zealand’s largest finfish fishery, and a predator on mesopelagic fish.

The Deep‐Sea Preyscapes of Mammalian Top Predators
Deep‐sea predator foraging is shaped by prey richness, accessibility, and density. Using eDNA and acoustics, we mapped fish and cephalopod communities across inshore‐offshore gradients around the Azores in foraging habitats of three co‐occurring deep‐diving toothed whales.

Tuna fishing accounts for over 70% of GDP in small island countries in the Western and Central Tropical Pacific. However, this activity is threatened by global warming, which could displace or reduce tuna populations.
