Longest coral bleaching in Singapore caused by warming seas

Published

on

The underwater gardens in Singapore have lost their color earlier this year caused by warming seas.

The sea warming was caused by the hottest climate on record this year, but this month some corals are starting to recover from the longest bleaching incident happened in the country.

Preliminary assessments by scientists here have shown that this year’s event is more severe than two other major bleaching events in 1998 and 2010.

On July this year, Rick Rigazio, an operations research analyst in the US Navy, Coast Guard, and Marines, posted Ed King’s report on World Meteorological Organization (WMO) in his Facebook, “The El Niño event, which turned up the Earth’s thermostat, has now disappeared. Climate change, caused by heat-trapping greenhouse gases, will not. This means we face more heatwaves, more extreme rainfall and the potential for higher impact tropical cyclones.”

Data from US National Oceanic and Atmospheric Administration and NASA published three months ago confirmed June was the 14th month in a row to break temperature records.

Decades-long trends of climate change are reaching new climaxes, fuelled by the strong 2015/2016 El Niño,” said WMO chief Petteri Taalas. WMO is a specialized agency of the United Nations whose mandate covers weather, climate and water resources.

Bleaching occurs when abnormally high sea temperatures cause corals to expel the zooxanthellae living in them, turning them white.

Zooxanthellae is a symbiotic algae, which is what corals depended on for food.

Dr Karenne Tun, director of the coastal and marine division at the National Parks Board’s (NParks) National Biodiversity Centre, said the bleaching event started in June and ended in September in 2010.

Dr Tun said, “The sea surface temperatures dipped to just below the bleaching threshold from early June, but continued to remain above the maximum monthly mean till early October.”

She said observations by scientists revealed that recovery from bleaching is still going on this month.

“But we are hopeful that the remaining bleached corals will recover within the next one to two months if the sea surface temperatures continue on their downward trend,” she added.

Bleach Watch Singapore also posted in its Facebook that the community observed the mass coral bleaching in Singapore in 2016.

And coral expert Chou Loke Ming, an adjunct research professor at the National University of Singapore’s Tropical Marine Science Institute said, the bleaching event lasted from June to August in 1998. But from end-April this year, water temperatures began exceeding the bleaching threshold which is 31.14C.

Water temperatures have since dropped to just below 30C, but is still above the average temperature of 29.6C expected at this time of the year.

Prof Chou added, “A bleaching event is considered to have ended when sea surface temperatures go back to normal.”

NParks has endeavored to aid in the corals’ recovery. For example, it has closed the dive trails at the Sisters’ Island Marine Park since June to minimise additional stress to the corals.

The dive trails will remain closed until the end of this month, Nparks said.

Prof Chou also said scientists are now following up on coral colonies affected to assess the survival rate; at the present, it was too soon to compare the impact.

Mortality was about 20 percent in 1998 and 12 percent in 2010. But in both cases, recovery was seen, he said.

Coral bleaching is not just restricted to Singapore, the Great Barrier Reef in Australia is also affected. But it has not died.

The coral reef system is too large to simply die off, said Prof Chou.

He deliberated that while some parts of the system may die, it is also possible to end up with reefs with a different composition of coral species, depending on which can thrive under the changed conditions.

Prof Chou concluded, “Singapore reefs have recovered from both bleaching events… and I take heart in reef resilience.”

Indonesia authorities caught foreign vessels dredging sand in Batam, bound for Singapore

Two foreign vessels, MV Yang Cheng 6 and MV Zhou Shun 9, were detained by Indonesia’s Ministry of Maritime Affairs and Fisheries for illegal sand dredging in the waters near Batam Island. The vessels, flagged under multiple countries, were found carrying sea sand destined for Singapore. Investigations are ongoing.

INDONESIA: The Indonesian Ministry of Maritime Affairs and Fisheries (KKP) has suspended the operations of two vessels, MV Yang Cheng 6 and MV Zhou Shun 9, suspected of illegal sand dredging in Batam Waters, Riau Islands.

The vessels, a dredger and a cargo ship, were seized on Wednesday (9 Oct) for allegedly operating without the necessary permits and documentation.

Although the ships were flying Malaysian flags at the time of the seizure, they were also displaying the flags of Singapore and the Republic of Sierra Leone.

According to the Marine Traffic website, both vessels are registered under the flag of Sierra Leone, a West African nation.

The MV Yang Cheng 6, specifically, is listed as 130 metres long, 20 metres wide, with a gross weight of 8,012 tonnes

The case was officially announced by the KKP during a press conference held on Thursday (10 Oct).

Key officials present included Minister of Maritime Affairs and Fisheries Sakti Wahyu Trenggono, Director General of Marine and Fisheries Resources Supervision (PSDKP) Pung Nugroho Saksono, Director General of Marine and Marine Space Management Viktor Gustaaf Manoppo, and KKP spokesperson Wahyu Muryadi, along with other senior officials.

Director General of PSDKP Pung Nugroho Saksono shared the sequence of events leading to the arrest.

While Minister Sakti was aboard the Orca vessel en route to Nipah Island on Wednesday (9 Oct) he passed the MV Yang Cheng 6.

The Minister immediately ordered an inspection of the vessel, which revealed that it lacked proper documentation, except for papers belonging to the ship’s captain.

“This ship has been under our surveillance for some time,” said Pung, adding that the MV Yang Cheng 6 had frequently entered Indonesian waters.

He emphasised that, to date, the Ministry has not issued any permits for sea sand extraction, as stipulated in Government Regulation (PP) No 26 of 2024 on the Utilisation of Marine Sedimentation.

Pung stated that while the investigation is still ongoing, preliminary inspections have found around 10,000 cubic metres of sea sand aboard the Yang Cheng 6.

This quantity represents a single dredging operation lasting nine hours.

He explained that the government had introduced PP No 26 of 2024 to regulate marine sedimentation extraction and prevent the illegal exploitation of Indonesia’s sea sand resources.

According to the ship’s captain, the vessel typically carries out ten sand suction operations each month, with plans to transport the sand to Singapore.

Captain denies illegal sand dredging

However, one of the crew members, who identified himself as the captain of the MV Yang Cheng 6, Tias, denied any involvement in illegal dredging activities in Indonesian waters.

He stated that the ship had completed sand extraction in Muar, Malaysia, and was on its way to Changi, Singapore, when it was intercepted by Indonesian authorities.

Tias explained that, according to international maritime border regulations, ships are required to pass through the Traffic Separation Scheme (TSS), a route close to Indonesian waters.

Tias insisted that the sand aboard the MV Yang Cheng 6 had been extracted from Malaysian waters, not from Indonesia.

However, he acknowledged that he was unable to present the ship’s documents during the inspection, explaining that the paperwork was stored at the shipping company’s office in Malaysia.

“That’s why we couldn’t produce the documents during the inspection,” he said.

He also emphasised that the ship’s activities had no connection to Indonesia and that the sea sand was intended for Singapore.

The two vessels are currently moored in waters near Batam.

Illegal dredging costs Indonesia over IDR 223 billion annually, official warns

The Director General of PKRL, Viktor Gustaaf Manoppo, estimated that Indonesia loses over Rp223.2 billion (approx. US$ 14.3 million) annually from the operations of a single illegal dredging ship.

This figure is based on the production of sand suction conducted each year. “While we continue to assess ecological damage, the financial losses to the state are already significant,” Viktor stated.

He further noted that the current price for one cubic metre of sea sand is  Rp186,000 (US$11.94), and calculated that the loss for a single ship amounts to Rp223.2 billion.

This estimate does not include other potential revenue losses, such as export duties and mining permits.

Viktor warned that if multiple ships are involved, the losses could skyrocket.

“We will continue to investigate the full extent of these operations, especially since much of this dredging likely occurs at night, making it difficult to monitor,” he concluded.

Hurricane Milton ravages central Florida, sparking tornadoes and power outages

Hurricane Milton hit Florida on 9 October, making landfall as a Category 3 hurricane. It caused widespread destruction, tornadoes, and power outages affecting nearly two million people. The storm’s impacts are felt across the state, including flash floods, damaged homes, and evacuation efforts.

Hurricane Milton swept across central Florida on 10 October, after making landfall on the state’s west coast the previous evening, causing extensive damage with strong winds, heavy rain, and tornadoes.

The storm initially struck near Siesta Key on 9 October at approximately 8.30 pm EDT (8.30 am Singapore time on 10 October), with winds reaching 195 km/h, classifying it as a Category 3 hurricane, according to the US National Hurricane Centre.

As the hurricane continued eastward through Florida, it weakened to a Category 1 storm by early 10 October, with maximum sustained winds of 150 km/h.

Despite this downgrade, the danger remained high, with severe rainfall and significant storm surges. The hurricane’s eye was about 75 km west-southwest of Cape Canaveral, which houses Nasa’s Space Force Station, at the time.

A flash flood emergency was declared for the Tampa Bay region, covering Tampa, St Petersburg, and Clearwater. The National Hurricane Centre reported that St Petersburg alone experienced 422 mm of rain on 9 October. Authorities warned that seawater could surge as high as 4 metres in certain areas, potentially inundating coastal communities.

Governor Ron DeSantis expressed hope that Tampa Bay would avoid the worst of the storm’s effects due to the timing of landfall before high tide.

However, Milton had already unleashed at least 19 tornadoes across the state, damaging numerous counties and destroying around 125 homes, including many mobile homes. “At this point, it’s too dangerous to evacuate safely, so you have to shelter in place and just hunker down,” Mr DeSantis said during a briefing following the storm’s landfall.

Tragically, at least two fatalities were reported at a retirement community in Fort Pierce on Florida’s eastern coast, following a suspected tornado, as cited by NBC News and St Lucie County Sheriff Keith Pearson.

The sheriff estimated that approximately 100 homes were destroyed by the tornadoes in the county, which saw about 17 touch down.

The hurricane caused significant power outages, leaving more than two million homes and businesses without electricity, according to data from PowerOutage.us. The storm was projected to move across Florida overnight before entering the Atlantic Ocean on 10 October, still maintaining hurricane strength.

The arrival of Hurricane Milton comes just two weeks after Hurricane Helene battered the southern United States, including Florida. State officials had already ordered the evacuation of up to two million residents ahead of Milton’s impact, with millions more remaining in its path. The cumulative damage from both hurricanes is expected to reach billions of dollars.

Florida’s recovery efforts were bolstered by federal support, with President Joe Biden being briefed on the situation by emergency response teams.

The Federal Emergency Management Agency (Fema) has mobilised significant resources, including millions of litres of water, meals, and personnel, to assist those affected by Milton, even as it continues recovery work following Hurricane Helene.

Governor DeSantis confirmed that 9,000 National Guard personnel and 50,000 utility workers were deployed to aid in clearing debris and restoring power. Search-and-rescue teams were on standby to begin operations as soon as conditions allowed. “It’s going to mean pretty much all the rescues are going to be done in the dark, in the middle of the night, but that’s fine. They’re going to do that,” he added.

Despite these efforts, the damage from Hurricane Milton remains severe. High waves nearing 8.5 metres were recorded offshore, while boats were beached in St Petersburg, adding to the destruction.

Many parts of Florida faced fuel shortages, with almost 25% of petrol stations running dry by the afternoon of 9 October as residents evacuated.

While the human toll is the most pressing concern, other local efforts included protecting animals at Tampa’s zoo, where staff sheltered African elephants, flamingos, and other species.

The zoo joined residents in bracing for the worst, highlighting the widespread impact of the hurricane.

Political Controversy Surrounding Federal Response

The hurricane’s approach has also intensified political disputes, particularly as the US prepares for elections.

President Biden condemned the spread of disinformation regarding the government’s hurricane response, describing it as an attempt to “undermine confidence” in rescue and recovery efforts.

Former President Donald Trump has been critical of the Biden administration’s handling of disaster relief, especially following the impact of Hurricane Helene.

Trump claimed that resources intended for disaster victims had been diverted to assist migrants, a claim which Fema has categorically denied, emphasising that no disaster relief funds were diverted for this purpose.

Fema noted that its Disaster Relief Fund remains separate from budgets designated for migrant assistance.

In a highly charged political climate, these statements have led to further scrutiny of the federal response. Nonetheless, Fema asserts that it has the resources necessary for immediate response and recovery operations following both hurricanes.
