Impacts of marine debris on coral reef ecosystem: A review for conservation and ecological monitoring of the coral reef ecosystem

Marine Pollution Bulletin, 2023
Coral reefs are the most spectacular underwater creation of nature. It enhances ecosystem functioning and marine biodiversity while also ensuring the livelihood of millions of coastal communities worldwide. Unfortunately, marine debris poses a serious threat to ecologically sensitive reef habitats and their associated organisms.

Reef Metabolism Monitoring Methods and Potential Applications for Coral Restoration

Environmental Management, 2022
Coral reef metabolism measurements have been used by scientists for decades to track reef responses to the globe's changing carbon budget and project shifts in reef function. Here, we propose that metabolism measurement tools and methods could also be used to monitor reef ecosystem change in response to coral restoration.

Can Coral Reefs Be Monitored from Space?

AMBIO: A Journal of the Human Environment, 2003
The dramatic bleaching events on the coral reefs recently have enhanced the need for environmental monitoring. Remote sensing is an important constituent for monitoring of reefs, and an invaluable complement to field observations. This paper discusses the possibilities and limitations of present high resolution satellites for mapping and monitoring ...

A demographic approach to monitoring the health of coral reefs

Marine Pollution Bulletin, 2005
Inshore coral reefs adjacent to the wet tropics in North Queensland, Australia, are regularly exposed to flood plumes from coastal river systems. Changes in the nature of these plumes have been linked to the declining health of coral reefs in the region.

Optimization of an energy harvesting buoy for coral reef monitoring

2013 IEEE Congress on Evolutionary Computation, 2013
The sustainable management of coastal and offshore ecosystems, such as for example coral reef environments, requires an energy efficient collection of accurate data across various temporal and spatial scales. To suitably address the energy supply of marine sensors, in this paper a novel energy harvesting device is proposed, based on a Tubular Permanent

Monitoring growth of hard corals as performance indicators for coral reefs

Journal of Biological Education, 2004
Digital videophotography, computer image analysis and physical measurements have been used to monitor sedimentation rates, coral cover, genera richness, rugosity, and estimated recruitment dates of massive corals at three different sites in the Wakatobi Marine National Park, Indonesia, and on the reefs around Discovery Bay, Jamaica.

Inconsistencies in ocean temperature monitoring for coral reefs

2022
Coral reefs are extremely vulnerable to climate-driven warming of the ocean, which threatens their existence. Multiple sea surface temperature (SST) data sources are currently used to study and predict coral responses to rising temperatures. Understanding the differences between the different SST data sources applied to coral reefs may facilitate ...

Foraminifera as Bioindicators in Coral Reef Assessment and Monitoring: The FORAM Index

Environmental Monitoring and Assessment, 2003
Coral reef communities are threatened worldwide. Resource managers urgently need indicators of the biological condition of reef environments that can relate data acquired through remote-sensing, water-quality and benthic-community monitoring to stress responses in reef organisms.

National Coral Reef Monitoring Program socioeconomic monitoring component

2016
This report outlines human dimensions information relevant to coral reef resources in American Samoa. The findings here are derived from a combination of data gathered through household surveys conducted in February 2014, and additional secondary sources of socioeconomic information for the jurisdiction.

Hawai'i Coral Reef Assessment and Monitoring Program: Spatial Patterns and Temporal Dynamics in Reef Coral Communities

Pacific Science, 2004
The Hawai'i Coral Reef Assessment and Monitoring Program (CRAMP) was established to describe the spatial and temporal variation in Ha- waiian coral reef communities in relation to natural and anthropogenic factors. Sixty permanent reef sites stratified by depth have been monitored in the main Hawaiian Islands since 1999 and formed the basis for ...
