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.

CORALBOT project: an initiative to monitor coral reefs

Innovare: Revista de ciencia y tecnología, 2021
The CORALBOT project was developed in 2019, as part of the Instituto Hondureño de Ciencia, Tecnología y la Innovación (IHCIETI) applied research projects. Images show the robot's first immersion in Punta Sal, Tela, Honduras, the final robot prototype and site´s coral reefs.

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.

IMAGE FUSION APPLIED TO SATELLITE IMAGERY FOR THE IMPROVED MAPPING AND MONITORING OF CORAL REEFS: A PROPOSAL [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
A coral reef ecosystem, one of the most complex marine environmental systems on the planet, is defined as biologically diverse and immense. It plays an important role in maintaining a vast biological diversity for future generations and functions as an ...

Coral reef carbonate accretion rates track stable gradients in seawater carbonate chemistry across the U.S. Pacific Islands

Frontiers in Marine Science, 2022
The U.S. Pacific Islands span a dramatic natural gradient in climate and oceanographic conditions, and benthic community states vary significantly across the region’s coral reefs.

Bleaching causes loss of disease resistance within the threatened coral species Acropora cervicornis

eLife, 2018
Determining the adaptive potential of foundation species, such as reef-building corals, is urgent as the oceans warm and coral populations decline. Theory predicts that corals may adapt to climate change via selection on standing genetic variation.

Coral Reef Health Index On Sangiang Island

Ilmu Kelautan, 2021
The coral reef is massive deposits of calcium carbonate produced from coral animals that are symbiotic with zooxanthellae. One of the activities carried out as an effort to improve the sustainability of coral reefs is monitoring the health condition of ...

Environmental DNA for Biodiversity Monitoring of Coral Reefs

, 2022
Coral reefs are globally significant repositories of marine biodiversity. Over 25% of all marine life depends on coral reefs at some point in their life cycle. Among the nine million species that live on the world’s coral reefs, many are undescribed.
