Prevalence of Stony Coral Tissue Loss Disease at El Seco, a Mesophotic Reef System off Vieques Island, Puerto Rico

Frontiers in Marine Science, 2021
Mesophotic coral ecosystems (MCEs) are ecologically and functionally vital, as they are Essential Fish Habitats that function as refugia for corals and sponges of shallow-water reefs.

Interacting Effects of Sea‐Level Rise and Ocean Warming Reshape Thermal Environments on a Coral Reef

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Sea‐level rise (SLR) alters nearshore hydrodynamics, yet its influence on coral reef thermal regimes under climate‐driven ocean warming remains poorly quantified. Using a fully coupled hydrodynamic–wave model validated at Palmyra Atoll, we isolate how SLR modifies temperature variability during a projected 2050 marine heatwave.

Light environment drives the shallow‐to‐mesophotic coral community transition

Ecosphere, 2019
Light quality is a crucial physical factor driving coral distribution along depth gradients. Currently, a 30 m depth limit, based on SCUBA regulations, separates shallow and deep mesophotic coral ecosystems (MCEs).

Cameras or Divers? How Baited Remote Underwater Videos and ‘Long Swims’ Underwater Visual Census Complement Each Other on Coral Reefs

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This study compares baited remote underwater videos (BRUV) and a rapid timed long swim (LS) UVC method to evaluate their ability in assessing relative abundance and diversity of large predatory reef fish from nine selected families. BRUVs were more effective in detecting mobile and bait‐attracted taxa such as Carangidae and recorded up to 28 unique ...

Flow structures over mesophotic coral ecosystems in the eastern Gulf of Mexico

Continental Shelf Research, 2020
Abstract Simultaneous time series of current velocity profiles are used to characterize flow structures over intermediate-depth coral ecosystems in the eastern Gulf of Mexico. Understanding of temporal variability and spatial coherence in flow is necessary to establish connectivity among these ecosystems.

Theme section on mesophotic coral ecosystems: advances in knowledge and future perspectives [PDF]

Coral Reefs, 2016
The Second International Mesophotic Coral Ecosystems (MCEs) workshop was held in Eilat, Israel, October 26-31, 2014. Here we provide an account of: (1) advances in our knowledge of MCE ecology, including the central question of the potential vertical connectivity between MCEs and shallow-water reefs (SWRs), and that of the validity of the deep-reef ...

Marine Heatwaves Have Increased in Frequency, Duration, and Depth Across Southeast Asia

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract Southeast Asia supports high marine biodiversity that is increasingly exposed to intensifying marine heatwaves (MHWs). Despite the ecological and socio‐economic consequences of thermal anomalies, the regional spatio‐temporal dynamics and vertical structure of MHWs remain poorly constrained. Here, we use satellite‐derived surface and reanalysis

Exploring the Biodiversity of Understudied Benthic Taxa at Mesophotic and Deeper Depths: Examples From the Order Zoantharia (Anthozoa: Hexacorallia)

Frontiers in Marine Science, 2019
Research on so-called “minor taxa” at mesophotic depths has lagged behind that of more commonly researched groups such as fish or hard corals. Exemplar taxa include species of the order Zoantharia, benthic colonial anemones that are cosmopolitan in ...

Possible monitoring of mesophotic scleractinian corals using an underwater mini-ROV to sample coral eDNA

Royal Society Open Science
Mesophotic coral ecosystems (MCEs) are light-dependent tropical or subtropical communities occurring at depths of 30–150 m. Broader surveys of MCEs are needed to better understand stony corals, the keystone species of coral-reef ecosystems.

Rapid Decreases and Performance Declines in Northeast Pacific Seamount Foundation Species Detected in an Oxygen Minimum Zone

Global Change Biology, Volume 32, Issue 4, April 2026.
Across 12 long‐term monitoring sites on three Northeast Pacific seamounts, 163 of 844 cold‐water coral and sponge individuals were lost between surveys 3–5 years apart, with abundance declining at five sites and condition (i.e., health) declining at nine.
