Scientists observed the bleaching of Australia’s Great Barrier Reef early this year using satellite images. While capturing these events from space has been difficult in the past, Sentinel-2’s frequent revisits and its resolution makes it possible.
BEIJING (AP) — A look at recent developments in the South China Sea, where China is pitted against smaller neighbors in multiple disputes over islands, coral reefs and lagoons in waters crucial for global commerce and rich in fish and potential oil and gas reserves:
Due to the unprecedented bleaching events over the past few years, the Great Barrier Reef has been eulogized extensively in the media. But it’s not actually dead. Yet. In this video for Vox, Joss Fong explains how corals form, bleach,...Show More Summary
Computer-led analysis of tourist snaps has estimated that coral reefs contribute $36 billion per year to the global tourist economy.
The early life history stages of coral are an essential component determining the recovery potential of coral reefs through sexual reproduction and recruitment. The pelagic larval phase is inherent in all coral species regardless of differing reproductive strategies and is the only time in coral life history where large scale movement is possible allowing for […]
(San Diego State University) Viruses are thought to frequently kill their host bacteria, especially at high microbial density. A state called lysogeny, in which viruses lie dormant but don't kill their hosts, has been thought to be relatively rare, mostly occurring at low bacterial concentrations. Show More Summary
Conventional wisdom has it that within virus-bacteria population dynamics, viruses frequently kill their host bacterial cells—a process called lysis—especially when there's a large concentration of bacteria. A different dynamic called...Show More Summary
When most people think of a coral reef they are imagining a sunny tropical beach, but many coral species are actually found in the dark, cold waters of the deep sea. These corals, commonly known as cold-water corals due to their preference for low temperatures, form beautiful ecosystems that are teeming with life. One of […]
So far, Google's AR program has taken 2 million kids to the coral reefs and space.
Coral reefs are currently experiencing substantial ecological impoverishment as a result of anthropogenic stressors, and the majority of reefs are facing immediate risk. Increasing ocean surface temperatures induce frequent coral mass bleaching events—the breakdown of the nutritional photo-symbiosis with intracellular algae (genus: Symbiodinium). Show More Summary
The Red Sea's coral reef may be able to beat climate change. Swiss and Israeli scientists have discovered that as temperatures rise, this special type of coral grows stronger. Read moremments
The vast majority of coral reef fish produce large numbers of young that disperse into the ocean as larvae, drifting with the currents before settling down on a reef. Giacomo Bernardi, a professor of ecology and evolutionary biologyShow More Summary
(University of California - Santa Cruz) The vast majority of coral reef fish produce large numbers of young that disperse into the ocean as larvae, drifting with the currents before settling down on a reef. A few reef fish, however keep their broods on the reef, protecting the young until they are big enough to fend for themselves. Show More Summary
WCS scientists have discovered a refuge for corals where the environment protects otherwise sensitive species to the increasing severity of climate change. The bad news is that the reefs are showing signs of being overfished and weak compliance with local fisheries laws needs to be reversed to maintain the fish that help to keep reefs healthy.

Reefs are being "essentially reset".
(University of Queensland) For reefs facing huge challenges, more coral larvae doesn't necessarily translate to increased rates of coral recovery on degraded reefs, a new Queensland study has showed. The study, published today, was led by former University of Queensland School of Biological Sciences researcher Dr. Show More Summary
The unique history of the Red Sea means that reefs in its northern part may be able to adapt to higher water temperatures, at least for a while
Marine reserves—sections of the ocean where fishing is prohibited—promote coral reef sustainability by preventing overfishing and increasing fish abundance and diversity. But to be effective, they need to be sized right, and in a way that accounts for how far juvenile fish travel away from their parents after spawning.
(Woods Hole Oceanographic Institution) Marine reserves -- sections of the ocean where fishing is prohibited -- promote coral reef sustainability by preventing overfishing and increasing fish abundance and diversity. But to be effective, they need to be sized right, and in a way that accounts for how far juvenile fish travel away from their parents after spawning.
As atmospheric CO? concentrations rise, associated ocean warming (OW) and ocean acidification (OA) are predicted to cause declines in reef-building corals globally, shifting reefs from coral-dominated systems to those dominated by less sensitive species. Show More Summary
