Decadal stability in coral cover could mask hidden changes on reefs in the East Asian Seas

Communications Biology, 2023
Coral reefs in the Central Indo-Pacific region comprise some of the most diverse and yet threatened marine habitats. While reef monitoring has grown throughout the region in recent years, studies of coral reef benthic cover remain limited in spatial and ...

CORAL REEF RESTORATION MONITORING MANUAL - Maldives

, 2022
In recent years, an increasing number of reef managers and practitioners have started to share successes, failures, and challenges of coral restoration projects due to the urgency to act in response to the impacts of climate change. The absence of a nationwide plan regarding the monitoring and reporting of restoration and rehabilitation efforts within ...

Global Monitoring of Coral Reefs [PDF]

Proceedings of OceanObs'09: Sustained Ocean Observations and Information for Society, 2010
Coral reefs are major shallow-water ecosystems lining the coastlines of the tropical and subtropical belt. They have served the needs of human societies over the millennia, but are now experiencing unprecedented rates of degradation due to combined effects of anthropogenic impact and global climate change.

Passive acoustic monitoring complements traditional methods for assessing marine habitat enhancement outcomes

Ecosphere, 2021
Habitat enhancement, often accomplished through the introduction of artificial structures, is a common strategy used by marine resource managers to provide habitat subsidies, protect sensitive habitat, and create new fishing opportunities.

Drone lidar-derived surface complexity metrics as indicators of intertidal oyster reef condition

Ecological Indicators, 2023
Eastern oysters (Crassostrea virginica) generate structurally complex reef systems that offer diverse ecosystem services. However, there is limited understanding of how reef structure translates into reef condition.

OysterSim: Underwater Simulation for Enhancing Oyster Reef Monitoring

OCEANS 2022, Hampton Roads, 2022
Oysters are the living vacuum cleaners of the oceans. There is an exponential decline in the oyster population due to over-harvesting. With the current development of the automation and AI, robots are becoming an integral part of the environmental monitoring process that can be also utilized for oyster reef preservation.

Switching between standard coral reef benthic monitoring protocols is complicated: proof of concept [PDF]

PeerJ, 2019
Monitoring the state of coral reefs is necessary to identify drivers of change and assess effectiveness of management actions. There are several widely-used survey methods, each of which is likely to exhibit different biases that should be quantified if ...

Remote Sensing of Coral Reefs for Monitoring and Management: A Review [PDF]

Remote Sensing, 2016
Coral reefs are in decline worldwide and monitoring activities are important for assessing the impact of disturbance on reefs and tracking subsequent recovery or decline. Monitoring by field surveys provides accurate data but at highly localised scales and so is not cost-effective for reef scale monitoring at frequent time points.

Beauty and the reef: Evaluating the use of non-expert ratings for monitoring aesthetic values of coral reefs [PDF]

Science of The Total Environment, 2020
Aesthetic values are a key driver of tourist and recreational visitation to natural areas and are listed among the selection criteria for World Heritage properties. However, assessment and monitoring of aesthetic values in natural areas, and coral reefs in particular, have proven to be challenging.

Advances in assessing Sabellaria spinulosa reefs for ongoing monitoring [PDF]

Ecology and Evolution, 2018
AbstractStandardized and repeatable data acquisition and analyses are required to enable the mapping and condition monitoring of reefs within Marine Protected Areas (MPAs). Changes in habitat condition must be reliably identified and reported to best support evidence‐based management.
