Unprecedented SSTs strike Florida's coral reefs

[HereWeGoAgain]

When did I ever say anything like that? The topic of this thread (mine, btw) is high SSTs harming Florida coral reefs. That seems to have shifted to the Great Barrier Reef where you tried to claim that WHOI was unreliable and that the Aussies had found their reefs doing just fine with all that hot water. I showed that to be completely incorrect using YOUR reference sources. That doesn't actually seem like the work of an idiot to me. And, as I just told someone else earlier today, misquoting someone is a no-no on this website.

It shifted to the Barrier Reef to prove to you this kind of shit is cyclical.

It shifted to the Barrier Reef to prove to you this kind of shit is cyclical.

When did you ever present a single iota of evidence indicating anything was cyclical?

WTF?
Are you fucking retarded?
The Great Barrier Reef was in trouble for awhile and now it's come back.
Would you hazard to take a guess why.

It's not coming back, but, so you're talking about cycles of a decade or two?

Climate change is the greatest threat to the world’s coral reefs. Marine heatwaves which cause coral bleaching are more frequent, extensive, intense and last longer. This means coral reefs have less time to recover between disturbances. Additional pressures, such as changes to the quality and acidity of seawater also impair reef recovery.​

Environmental change is predicted to continue. Reefs are resilient, but coral reef animals and plants must become more able to cope with stressful conditions to survive into the future. It is not yet clear if their rate of adaptation is fast enough to keep up with changing conditions.​

From the Great Barrier Reef Marine Park Authority's April 2023 Reef Health Update

The hotter-than-usual start to the month exposed much of the northern and central regions of the Reef to heat stress. ​

At the end of April, sea surface temperatures were, on average, 27°C across the Reef, which is 0.7°C above the long-term average for this time of year. The northern region experienced the highest anomalies at almost ~1°C above average.​

Rain may continue across the Reef in the coming weeks due to a pulse in the Madden–Julian Oscillation, but this is not expected to greatly influence overall rainfall during the tropical dry season.​

Reef health​

Of the 1273 surveys submitted between 26 March and 26 April, 955 were Reef Health Impact Surveys (RHIS).​

These surveys indicated that across the Marine Park, minor coral bleaching, disease, and damage continue to be reported. At the same time, anecdotal evidence of scattered bleaching was also received from the central region after the increase in temperatures earlier in the month.​

From Woods Hole Oceanographic Institutiion

Since 2016, reef experts and marine park authorities have been in a near-constant state of damage control. Marine heatwaves, pollution, and a voracious outbreak of coral-eating crown-of-thorns starfish (COTs) have delivered sucker punch after heart-wrenching sucker punch to this popular world wonder. In 2020, a study funded through an ARC Center for Excellence found that roughly half of the Great Barrier Reef’s corals had disappeared in the last few decades, with the remainder projected to vanish in the next century if we don’t curb planetary warming. In early 2022, following four of the biggest marine heatwaves in the GBR’s history, the fever briefly broke, opening a small but significant window for some species to reclaim territory. One part of why scientists are still wary of the reef’s future has to do with which of these species are returning more than others.​

​

According to AIMS’s Long Term Monitoring Program, most are a weedy genus of fast-growing corals known as Acropora. These include species like staghorn, elkhorn, and tabletop corals, which, though prolific, are easily broken up by cyclones—weather events that are expected to become more frequent and intense. Worse, they’re a favorite food for COTs, a species that continues to grow more comfortable on the Great Barrier Reef as surrounding waters warm.​

“Instead of a diverse, old-growth forest, [the reef] may now be like a monoculture of planted pulp trees,’” says Hughen. With less diversity of corals on the Great Barrier, he adds, there will also be fewer structures that house and feed various species of fish and marine invertebrates. Some, like the parrotfish—a valuable grazer that keeps algae from smothering corals—have already suffered decline in the northern third of the reef following mass bleaching events that began in 2016. ​

​

So how do we know whether to celebrate recovery on the Great Barrier Reef? This opens a long-held debate about the distinction between words like “recovery,” “recovered,” and “healthy.” ​

​

“Health depends on your perspective,” says Hughen. “There’s a lot of variability on any given reef, so these things aren’t just perfect until they’re messed with. They’re in flux.” ​

​

And not all scientists assess reef health in the same way. A coral biologist, for instance, may be excited at the prospect of higher coral cover, says Hughen, while a marine chemist on the same reef may find the presence of stress hormones a troubling sign. Hughen, along with colleagues on the Reef Solutions Initiative Team, are working to develop health diagnostic tools by factoring multiple indicators together—things like reef soundscapes, microbial communities, biochemical cues, and biodiversity levels. ​

​

“We’re trying to create baselines for what ‘healthy’ reefs look like,” says Hughen. ​

​

Currently, assessing coral cover alone can be a daunting task given the scale of the Great Barrier Reef. At more than 134,000 square miles, the reef is already bigger than the U.K., Switzerland, and Holland combined. In addition to aerial surveys, scientists with the Long Term Monitoring Program make observations by using manta tows, a technique where a snorkeler is towed in the water behind a boat to make visual assessments of coral cover, bleaching, and the presence of apex predators (among other things). ​

Like most coral reefs, the Great Barrier Reef has always experienced natural highs and lows in coral cover and biodiversity. How low those lows are, says Hughen, can tell us more about the overall impacts from human activity and climate change. During this latest period of regrowth, the Northern and Central Great Barrier reefs saw an average increase in coral cover back to 36%—up from a historic low of 27%. This may be short-lived, as the Intergovernmental Panel on Climate Change projects an additional die-off of 70-90% of global corals if the world reaches 1.5°C (2.7°F) of warming. ​

​

There is still some encouraging news here. Despite multiple stressors like marine heatwaves, COTs, pollutants from agricultural runoff, and overfishing, this regrowth period demonstrates that the Great Barrier Reef is able to bounce back—even with one less pressure. ​

​

“The point is that reefs are resilient and they’re always recovering, even if not fully recovered,” Hughen emphasized. “The question is whether we’re going to keep impacting and damaging them faster than they can come back.”​
