GCRMN Pacific Workshop – November 2023
From 16 – 18 November, the Global Coral Reef Monitoring Network (GCRMN) Pacific Regional Node convened in Auckland, New Zealand, for a productive workshop to drive the production of the “Status and Trends of Coral Reefs in the Pacific: 2024” regional report. The GCRMN Pacific node coordinators are currently working on the production of […]
NOAA unveils new tool for exploring coral reef data
First-ever NOAA Geoplatform tool shows shallow coral reef ecosystem trends NOAA’s National Coral Reef Monitoring Program (NCRMP) has launched a new data visualization tool, which will provide free and easy-to-access information on the status of U.S. coral reefs. It is the first tool focusing on shallow tropical coral reef data to be hosted on the NOAA […]
A Guide to Large-Area Imaging for Coral Reef Monitoring, Research and Restoration
National Centres for Coastal Ocean Science (NCCOS) and partners are using large-area imaging (LAI) to monitor shallow water coral reefs and restoration. Now, they’ve published a guidance document outlining standard operating procedures and concepts of photogrammetry (the science of making measurements from photographs), so members of the coral reef research and restoration community can apply these techniques […]
Unprecedented marine heat wave on Caribbean coral reefs
Decades of overfishing, habitat destruction, and eutrophication have led to a drastic decrease of hard coral cover across coral reefs in the Caribbean (Gardner et al., 2003). In addition to these historical local stressors, coral reefs face the adverse effects of climate change, specifically the increase in frequency and extended durations of marine heat waves […]
GCRMN Steering Committee Meeting
The GCRMN organised a two day steering committee meeting in Kailua-Kona, Hawai’i, on September 18th and 19th. This meeting was held in conjunction with the 37th ICRI general meeting and marked the first in-person gathering of the GCRMN steering committee since the March 2022 meeting in Monaco. A total of 31 participants, including seven node […]
Pacific hard coral identification online workshop
One of the most widely used indicators of coral reef state is the percentage cover of benthic organisms. Because of the huge diversity hosted by coral reefs, the cover of benthic species is usually aggregated in large categories, such as hard coral cover or macroalgae cover. This aggregation is mainly justified by a trade-off between […]
Pacific coral reef shows historic increase in climate resistance
Coral reefs in one part of the Pacific Ocean have likely adjusted to higher ocean temperatures which could reduce future bleaching impacts of climate change, new research reveals. Photo Credit: Ocean Image Bank // Tracey Jennings A Newcastle University-led study focused on the Pacific Island Nation of Palau and has shown that historic increases in […]
Pause in recent coral recovery on much of Great Barrier Reef
In-water monitoring by the Australian Institute of Marine Science (AIMS) shows hard coral cover across the Great Barrier Reef remains at similar levels to that recorded in 2022, with small decreases in the Northern, Central and Southern regions. Published on (Wednesday 9 August), AIMS’ Annual Summary Report on Coral Reef Condition for 2022/23 found that […]
GCRMN Reef Encounter Article: Values of a long-term partnership
Since 1995, the Global Coral Reef Monitoring Network (GCRMN), an operational network of the International Coral Reef Initiative (ICRI) has nurtured a global community dedicated to coral reef conservation by providing a platform to exchange data and share knowledge, expertise, innovative ideas and diverse perspective. Utilising data from a range of techniques, from ground-level […]
2023 Coral Bleaching Guidance
Coral Restoration Consortium releases guidance to practitioners on coral bleaching Bleaching is reaching severe levels throughout the tropics with more reports coming in daily. This extreme heat stress due to the predicted El Niño, is arriving a month earlier than expected. Corals can recover from mild or short-term bleaching but long-term or extreme heat causes […]
