This is an important part of the explanation of why heat stress on the Reef accumulated so rapidly during February.
This difference between and will likely have consequences for the extent and severity of coral bleaching. We will closely monitor Reef health in the coming month to track these consequences.
With stronger winds, cloud cover and rain over the Reef, we are starting to observe sea surface temperatures reducing across the Reef.
Water temperatures at all the Australian Institute of Marine Science weather stations within the Reef have reduced over the last two days, but these will be monitored to determine whether this is a long-term trend.
Observations during aerial patrols conducted between Townsville and Mackay and the Capricorn-Bunkers over 6 to 8 March in the areas where there is the greatest thermal stress accumulation.
The most severe bleaching was observed on inshore reefs. In the Capricorn-Bunker group, there was a bleaching gradient observed, with more severe bleaching in the northern reefs.
There was less in the southern reefs of this group, however, there was indications of thermal stress at all reefs visited.
There are further observations of minor and patchy bleaching throughout many other areas of the Reef.
To date, offshore reefs those closest to the edge of the continental shelf show little to no signs of bleaching. Local weather conditions over the next few weeks will play a key role in determining overall outcomes for the Reef this summer.
The tropical low pressure system currently situated off the east coast of Australia will create unsettled weather across the Reef, which is currently resulting in cooling of Reef waters.
The Marine Park Authority is working with our partners to best understand the health of the Reef this summer.
On 17 March , aerial surveys to assess the extent and severity of coral bleaching are scheduled to commence across the Great Barrier Reef.
Experience has shown this is the best and most effective way to understand where coral bleaching has, and has not, occurred and the severity of coral bleaching across the expanse of the Reef.
The flights are timed to coincide with the anticipated peak of coral bleaching across the Reef, when corals are white or fluorescing and most visible from the air.
This will ensure we have an accurate understanding of the patterns of bleaching that are present. The surveys will follow the past flight paths of and surveys.
The flights will take about nine days over about a two week period, dependent on weather. Cloud and rain over the last few weeks cooled parts of the Great Barrier Reef and sea surface temperatures remained relatively stable this week.
These sea surface temperatures are, however, generally above what is expected at this time of the year. There are some inshore areas, particularly in the southern management area, which are up to 2.
While recent cloud and rain provided cooling to some parts of the Great Barrier Reef, we are continuing to monitor the situation because the risks have not gone away.
Local weather conditions over the next few weeks will play a key role in determining outcomes for the Reef this summer.
Coral bleaching has been occurring on parts of the Reef where thermal stress has accumulated the most over summer. A variety of information is used to understand conditions, including in-water temperature loggers monitored by the Australian Institute of Marine Science and satellite observations from the Bureau of Meteorology.
In-water temperature loggers monitored by the Australian Institute of Marine Science currently indicate cooling over the last week at most locations across the Reef.
Recent cloud cover may have restricted the ability of some satellites to accurately measure sea surface temperatures. As a result, modelled sea surface temperatures may appear warmer than it actually is, so data should be interpreted with caution.
These show inshore and mid-shelf reefs assessed in the far north north of Princess Charlotte Bay mostly have widespread bleaching affecting most coral types, whereas offshore reefs assessed in this area show minimal to no bleaching.
Observations over large parts of the remainder of the Reef show no bleaching or isolated minor coral bleaching. For example, observations of reefs from Bowen to offshore Mackay and mid shelf reefs between Ingham and Cairns showed no or minimal coral bleaching during aerial surveillance last week and into the weekend.
In some other locations, such as Cleveland and Halifax bays near Townsville, moderate to severe bleaching was observed on inshore fringing reefs.
As of 26 February , most of the Great Barrier Reef coast and catchment received rainfall, with the highest totals falling just north of Mackay. Most river systems within the Marine Park catchment are currently below flood level.
Salinity levels remain mostly normal, however some inshore areas between Townsville and Port Douglas and a small area near the Fitzroy River recorded lower salinity levels.
Water temperatures across the Reef are increasing and reaching levels where some bleaching is being observed. We are investigating this — spot checks by divers, helicopter patrols, and citizen science observations are helping us build a bigger picture.
As was the case last summer, local and regional weather conditions have the potential to change this outlook and are a critical factor in outcomes this summer.
However, with current thermal stress observations and forecasts, further bleaching may develop in the Great Barrier Reef this summer. As of 11 February , most of the Great Barrier Reef coast and catchment received rainfall, with the highest totals falling in the northern Cape York Peninsula and in the Fitzroy River catchment.
All rivers systems within the Marine Park catchment are currently below flood level. Salinity levels remain mostly normal, apart from a small area in Princess Charlotte Bay and coastal areas near the Tully and Herbert rivers where lower salinity levels were recorded.
These areas also accumulated the most thermal stress since the start of summer. However, there is variability between the satellite-based models and more local in-water readings.
In-water temperature loggers monitored by the Australian Institute of Marine Science currently indicate a high risk of bleaching at Myrmidon Reef and an extreme risk of bleaching at Davies Reef —both in the Central management area.
A medium risk of bleaching is indicated in the Keppel Islands, with loggers in the northern half of the Marine Park indicating no or low risk of bleaching.
It is expected to continue moving slowly to the southwest and expected to cause destructive winds at Lord Howe Island later today. As of 3 February , most of the Great Barrier Reef coast and catchment received rainfall, with the highest totals between Cooktown in the far north and Cape Upstart in the south.
As of 4 February , most of the Marine Park was 0. These areas have also accumulated the most thermal stress since the start of summer. In-water temperature loggers monitored by the Australian Institute of Marine Science are currently indicating a medium risk of bleaching at Heron Island and in the Keppel Islands, with loggers north of these indicating no or low risk of bleaching.
There is currently a tropical low located over the northern Coral Sea. This system is not expected to develop significantly in the short-term, but may strengthen towards tropical cyclone intensity late this weekend or early next week.
A tropical low near the southern coast of the Gulf of Carpentaria caused significant rainfall and cloud cover across northern Australia over the past week, including across the Great Barrier Reef catchment.
Most of the Great Barrier Reef coast and catchment received rainfall, with the highest totals between Princess Charlotte Bay in the far north and Shoalwater Bay in the south.
The recent rain and cloud cover conditions over much of the Marine Park may have some cooling influence on sea surface temperatures over the coming weeks and this will continue to be monitored.
As of 27 January, some inshore to mid-shelf areas in the Far Northern and Southern management areas were 2 to 2. These are the areas that have also accumulated the most thermal stress in the Marine Park since the start of summer.
Local and regional weather conditions will have a key influence on sea surface temperatures over the next few weeks, and we will continue to monitor the situation closely.
From Cairns to the southern boundary of the Marine Park, most inshore to mid-shelf areas are on Warning, while outer shelf areas are on Watch.
In-water temperature loggers monitored by the Australian Institute of Marine Science are currently indicating a high risk of bleaching at Thursday Island in the Torres Strait, and a medium risk of bleaching at Lizard Island in the northern Marine Park.
All other logger locations south of Lizard Island currently indicate no or low risk of bleaching. Reports from our Eye on the Reef network indicated isolated instances of low level coral bleaching and coral disease in the Marine Park.
Sea surface temperatures in the Marine Park increased over the past week, mainly within the central and southern inshore areas in and throughout the far northern management area.
Above-average air temperatures are expected to persist for much of the country into April, with a roughly equal chance of wetter or drier conditions than average during this period.
Forecast tools from the Bureau and the National Oceanic and Atmospheric Association currently predict a moderate risk of thermal stress throughout all sectors of the Marine Park over the coming months, but particularly within inshore areas.
An area within the Torres Strait is on Bleaching Alert by the National Oceanic and Atmospheric Administration with elevated water temperatures concentrated to the north west of the region.
The latest Australian Institute of Marine Science survey reports for the far northern area of the Great Barrier Reef show overall hard coral cover in the Cape Grenville and Princess Charlotte Bay sectors was moderate 10 to 30 per cent.
Per cent coral cover in Cape Grenville was unchanged while there was a slight decrease in Princess Charlotte Bay. Coral bleaching was widespread, but restricted to low levels, with no crown-of-thorns starfish outbreaks reported.
Sea surface temperature anomalies in parts of the Marine Park increased slightly over the past week, mainly in the Far Northern area.
Above average temperatures are likely to continue for much of Australia into April. Most of eastern Queensland is likely to be drier than average through to the end of this month.
Forecast tools from the Bureau and National Oceanic and Atmospheric Administration currently predict a moderate risk of thermal stress throughout the Marine Park over the coming months.
Reports from the Eye on the Reef network have indicated only isolated instances of low level coral bleaching and coral disease in the Marine Park.
Active crown-of-thorns starfish outbreaks continue in the central and southern Marine Park. Above-average temperatures are likely to continue for much of Australia including Queensland into April.
Most of eastern Australia is likely to be drier than average through to the end of this month.
Forecast tools from the Bureau and National Oceanic and Atmospheric Administration currently predict a moderate risk of thermal stress in the Marine Park over the coming months.
The first tropical cyclone of the season for Australia, tropical cyclone Blake, made landfall on Wednesday morning 8 January in Western Australia.
A second tropical system currently over the Arafura Sea west of the Pacific Ocean is forecast to develop to tropical cyclone intensity in the coming days, potentially making landfall on the north coast of the Northern Territory in Australia.
There are currently no significant tropical low systems in the eastern region and none expected to develop. Rainfall across northern Australia has been well below average, with most of the tropics receiving less than 20 per cent of normal December rainfall.
In the past few days, a low intensity heat wave has been affecting most of Queensland, apart from isolated areas along the coast. The southwest and western parts of the State reported severe heatwaves.
The Bureau of Meteorology BoM ReefTemp tool indicates there is currently a low level of thermal stress accumulation throughout the Marine Park, and it is probable that this heating over the past few weeks has negated any buffer that existed in the Marine Park following a cooler winter.
The patterns of above-average temperatures and below-average rainfall are predicted to continue for northern Australia, at least until the monsoon becomes established in mid- to late-January — this is likely to mean calm, clear and dry conditions for the next few weeks which could likely contribute to thermal stress accumulation.
Reports on another round of coral spawning have been received through the Eye on the Reef sightings network. Conditions are currently hot and dry across the Great Barrier Reef catchment and are likely to remain so well into January.
Over the past few days, a low intensity heat wave has been affecting most of Cape York Peninsula. The United States National Oceanic and Atmospheric Administration NOAA uses satellite sea surface temperature monitoring to determine where coral bleaching stress reaches various levels.
The National Oceanic and Atmospheric Administration has placed this area on bleaching watch, along with parts of the Torres Strait and the Gulf of Carpentaria.
Sea surface temperatures are also slightly warmer than average in the inshore areas of the southern Marine Park however there is currently no bleaching watch for this area.
In the remainder of the Marine Park, sea surface temperatures are average to below average. A low level of thermal stress is beginning to accumulate throughout the region, however there is currently no threat of significant thermal bleaching for the majority of the Marine Park.
The Reef Joint Field Management Program crown-of-thorns starfish COTS response team recently returned from the Whitsundays region where they surveyed eight offshore reefs of high tourism and ecological value.
While there was evidence of crown-of-thorns on some of these reefs, no outbreaks were found. In addition, while the impacts of Cyclone Debbie are still visible across these reefs, signs of recovery were observed in some areas.
Monitoring will continue, and our proactive crown-of-thorns starfish control measures will be undertaken if necessary, to prevent potential outbreaks developing on these high value reefs.
We will take a short break from reporting on Reef health during the festive season, however conditions will still be closely monitored over this time.
If you are out on the Reef over the holidays, we remind you to stay safe and also make sure that you are familiar with the Marine Park rules, including zoning restrictions.
Free zoning maps are available from local bait and tackle shops or visitor information centres, or by downloading the free Eye on the Reef zoning app.
Any suspected illegal activity can be reported to our free hour hotline or online — information on how to do this is available on our website. Anyone can also report interesting sightings or reef health incidents through the Eye on the Reef app, so we can all play a part in keeping an eye on the reef this holiday season.
We are now officially at the start of summer. Spring was officially the fourth driest and the fifth warmest Spring on record for Queensland.
Conditions are hot and dry across the Great Barrier Reef catchment. This is directly due to the low to severe intense heatwaves over the last few days.
Heatwaves are expected to continue to affect the region over the coming days. Sea surface temperatures throughout the Marine Park are average to below average, with no current threat of significant thermal bleaching.
We use a specific tool designed to determine the accumulation of thermal stress in the Marine Park including mapping of Degree Heating Days. Models indicate there appears to be some level of thermal stress beginning to accumulate in some inshore regions from Townsville south and in the inshore to mid-shelf regions from Mackay south.
Forecast tools from the Australian Bureau of Meteorology and United States National Oceanic and Atmospheric Administration indicate some level of thermal stress is likely to be seen throughout the Marine Park by the end of January.
Areas to watch for coral bleaching in December and January include the central and southern management regions between the Bowen and Gladstone regions.
Large suspended algae blooms have been reported via the Eye on the Reef sightings network. This is normal for this time of year and thought to be associated with the annual coral spawning event.
If you witness further algal blooms through the Marine Park, submit the sighting via the Eye on the Reef app or sightings network. Home The Reef Reef health.
