A benthic substrate classification method for seabed images using deep learning: Application to management of deep‐sea coral reefs

Journal of Applied Ecology, Volume 60, Issue 7, Page 1254-1273, July 2023., 2023
The availability of much larger volumes of automatically annotated image‐derived data will improve spatial management of impacts on coral‐based VMEs in the deep sea by (1) improved cross‐validation and performance of spatial models required to predict coral distribution and abundance over the large scales of managed areas, and (2) establishing ...

Seamount coral reefs are egg case nurseries for deep‐sea skates

Journal of Fish Biology, Volume 102, Issue 6, Page 1455-1469, June 2023., 2023
Abstract Egg case nurseries of the boreal skate (Amblyraja hyperborea) and Richardson's skate (Bathyraja richardsoni) were defined and mapped on a bathyal seascape (c. 500–1900 m depths) south of Tasmania, Australia, using 99 towed‐camera transects (157 linear km; N = 50,858 images).

Corals and Carbon: The physiological response of a protected deep-sea coral (Solenosmilia variabilis) to ocean acidification [PDF]

, 2021
<p>Calcifying corals provide important habitat complexity in the deep-sea and are consistently associated with a biodiversity of fish and other invertebrates. Little is understood about how deep-sea corals may respond to predicted scenarios of ocean acidification (OA), but any predicted changes will have wider impacts on the ecosystem.   Colonies

Determining Coral Density Thresholds for Identifying Structurally Complex Vulnerable Marine Ecosystems in the Deep Sea

Frontiers in Marine Science, 2020
Vulnerable marine ecosystems (VMEs) are at risk from the impacts of deep-sea trawling. Identifying the presence of VMEs in high seas fisheries management areas has to date relied mainly on presence records, or on habitat suitability models of VME ...

Benthic foraminiferal faunas associated with cold‐water coral environments in the North Atlantic realm

The Depositional Record, Volume 7, Issue 2, Page 223-255, June 2021., 2021
Surface benthic foraminiferal assemblages associated with cold‐water coral mounds and reefs from the North‐east Atlantic (Irish margin and Norwegian shelf) share a common assemblage, dominated by elevated epibenthic and distinct infaunal species. This surface assemblage is typical for environments that are subject to strong bottom‐water turbulence with

Species replacement dominates megabenthos beta diversity in a remote seamount setting. [PDF]

Sci Rep, 2018
Seamounts are proposed to be hotspots of deep-sea biodiversity, a pattern potentially arising from increased productivity in a heterogeneous landscape leading to either high species co-existence or species turnover (beta diversity).

Global‐scale genetic structure of a cosmopolitan cold‐water coral species

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 31, Issue 1, Page 1-14, January 2021., 2021
Abstract 1.When considering widely distributed marine organisms with low dispersal capabilities, there is often an implication that the distribution of cosmopolitan species is an artefact of taxonomy, constrained by the absence of characters for delimiting either sibling or cryptic species.

Characterising and predicting benthic biodiversity for conservation planning in deepwater environments. [PDF]

PLoS One, 2012
Understanding patterns of biodiversity in deep sea systems is increasingly important because human activities are extending further into these areas. However, obtaining data is difficult, limiting the ability of science to inform management decisions. We

A Geophysical Review of the Seabed Methane Seepage Features and Their Relationship with Gas Hydrate Systems

Geofluids, Volume 2021, Issue 1, 2021., 2021
Seabed methane seepage has gained attention from all over the world in recent years as an important source of greenhouse gas emission, and gas hydrates are also regarded as a key factor affecting climate change or even global warming due to their shallow burial and poor stability. However, the relationship between seabed methane seepage and gas hydrate

True Size Matters for Conservation: A Robust Method to Determine the Size of Deep-Sea Coral Reefs Shows They Are Typically Small on Seamounts in the Southwest Pacific Ocean

Frontiers in Marine Science, 2020
Protection of vulnerable marine ecosystems (VME) is a critical goal for marine conservation. Yet, in many deep-sea settings, where quantitative data are typically sparse, it is challenging to correctly identify the location and size of VMEs.
