In late December, Indonesian cargo ship MV Namse Bangdzod vanished in local waters. The tanker, gross tonnage around 1,150 and loaded with crude palm oil, had over ten crewmembers. Wikinews examined data and contacted experts and local authorities in an effort to establish further details.

The exact date of disappearance is unclear, with industry publications reporting either December 27 or December 28. Crew totals are also unclear, with both eleven and twelve reported by industry sources while The Jakarta Post reports a captain and eleven other crew. Wikinews has contacted the Command and Control Centre of the Coast Guard seeking to clarify, among other things, the date of the disappearance and is awaiting a response.

Wikinews is also awaiting responses from both the Coast Guard and the National Search and Rescue Agency detailing the efforts being made to find the ship, which was last known to be in the Java Sea. MV Namse Bangdzod sailed with cargo from Sampit, a port town on a river in Borneo; it was last bound for Jakarta. It is owned and operated by Indonesian companies and also registered in Indonesia. The 75 m (250 ft) ship was built in 1993 in Japan.

Ships broadcast their position and other information via both the Automatic Identification System (AIS) and the Long Range Identification and Tracking (LRIT) system. AIS is a ship-to-ship safety system, but can also be detected from further afield by satellites. Marine Traffic’s AIS tracking database shows a reestablishment of AIS contact by MV Namse Bangdzod on January 6, with a pattern described by Marine Bulletin as “rather hectic and kind of confused”. In addition to asking local authorities, Wikinews sought expert input on the AIS data.

Dr. Tristan Smith of University College London, a shipping researcher with expert experience interpreting AIS results, explained to Wikinews that crews might turn their AIS transponders off on purpose for security reasons, such as “in certain sea areas where piracy is a risk” in order to “avoid attracting unwanted attention. This can involve them being turned off for several days at a time.” Doug Miller of Milltech Marine, a firm specialising in AIS, told our correspondent an AIS transponder will broadcast automatically provided it has power and antennae, even if the crew abandoned the vessel.

Baslan Damang, a security official from the port of departure, on Tuesday told The Jakarta Post radio broadcasts were being used to alert other traffic such as fishing vessels to look out for MV Namse Bangdzod. He added authorities “are still waiting for updates on the tanker’s condition, so please refrain from speculating that it had been hijacked”. As of yesterday, no oil slicks or other evidence of accidents have been found along the scheduled route the vessel was due to take. A major search continues.

Miller and Smith both acknowledged faults with the AIS system on-board as possible explanations, with Miller describing issues with the signal between the transponder and the satellite receiving it as one potential scenario for intermittent data reception. He too suggested a hypothetical scenario, in which “the AIS equipment has been tampered with or has been turned off for some of the time — either intentionally or accidentally or due to a power malfunction.” Smith called the disappearance an “interesting” case; Miller said “It is a little hard to definitively say what’s going on”. Miller explained that while transponders generally transmit every ten seconds “even if the transponder is transmitting there is no guarantee that other vessels or MarineTraffic can see it”. “It could also be a power supply issue or faulty transponder”, said Smith.

Smith told Wikinews “There are also some operations done on ships containing hazardous cargoes[…] where all risks of sparking/arcs need to be removed and radio transmitting equipment is sometimes turned off for this reason.” He said this applied to product tankers, but the long duration of AIS downtime would in this instance be unusual if this is the reason. Smith had one more theory: Namse Bangdzod could be the victim of identity theft, with a second vessel conducting manoeuvres it wished to conceal while falsely transmitting information identifying itself as Namse Bangdzod. Smith told Wikinews this might happen in cases of illegal fishing. He stated “In this scenario, it would normally be expected that both the legal and illegal transmission would be received but depending on how Marine Traffic handle this, it’s possible the two signals could be confused.”

Smith drew attention to LRIT as another method for search and rescue personnel to find the tanker. Unlike AIS, which is a safety and tracking system, LRIT is used for maritime security by seagoing nations. Created under the auspices of the International Maritime Organization, LRIT allows states to examine data about ships bearing their flag, visiting their ports, or in or near their waters.

Like all vessels exceeding 300 tons, Namse Bangdzod is required to transmit LRIT data. Search and rescue bodies can also access this information; Smith told Wikinews he believed this would include foreign navies with ships in the Java Sea. Singapore, India, and Australia have in the past conducted emergency searches of the Java Sea: All three nations offered military assistance after Indonesia AirAsia Flight 8501 vanished in December 2014.

Marine Traffic’s website’s most recently publicly available AIS result, as of Tuesday, showed the ship underway a few miles off Jakarta. VesselFinder listed no AIS results for the last month. Vessel Tracker’s database had no sighting of the ship within the last 59 days on Tuesday; the website noted the AIS signal received from Jakarta but declared the ship was not actually there. Maritime Connector has an entry for the ship in its database but has no location data available.

Local authorities, according to Maritime Bulletin, have noted other unusual AIS data. The website yesterday suggested piracy, perhaps to obtain the valuable cargo, is now the most prominent theory. The Indonesian Palm Oil Producers Association reports a value of US$473.60 per metric ton of crude palm oil as of November 2018, with the price decreasing that month. “Its plausible that an explanation [why] the AIS transponder is not transmitting is that it had been turned off by pirates who wanted to hamper the efforts of a rescue mission” Smith told Wikinews yesterday.

Yesterday the Search and Rescue Agency told The Jakarta Post it was intending to end its search on the basis of piracy, which is outside its remit; the paper also spoke to the Navy, who told it this was as-yet uncomfirmed and noted no ransom has been sought and the ship vanished from an area without previous piracy problems. Four Navy ships assisted by aircraft are searching. “We will continue searching until we find it,” 1st Fleet Command’s Navy Information Agency head Arba Agung told The Jakarta Post, which also today reported location data falsely showing the ship in Sunda Kelapa Port after its inaccurate position in Jakarta Bay was recorded.

Three of Sweden’s ten nuclear reactors have been shut down due to safety concerns following an incident last week at the Forsmark Nuclear Power Plant, in which the reactor cooling systems failed. The reactor has since been shut down there. After the incident, the Swedish Nuclear Power Inspectorate, SKI asked all the nuclear power plants to demonstrate that the same failure could not happen in them. On Wednesday, two more reactors at Oskarshamn were shut down after the operator said their safety could not be guaranteed.

Last week’s incident at the Forsmark plant was triggered by a short circuit that cut power to the reactor cooling system. Two of the four backup generators also failed to start, but the remaining two worked and were sufficient to meet the plant’s needs. Greenpeace reports that the fault in the backup power systems were traced to new equipment installed in 1993.

The spokesman of the Swedish Nuclear Power Inspectorate Anders Bredfell denied that there was any danger of a meltdown, adding that there was also a backup gas turbine to power the cooling system in an emergency.

However, Lars-Olov Höglund, who was responsible for the nuclear plant Forsmark for many years, said the incident was the most dangerous one since Chernobyl and Three Mile island, and that a meltdown was avoided only by pure luck. His views have however been questioned as he is involved in litigation with the Swedish nuclear industry and is known as an outspoken nuclear critic. Researchers at the Royal Institute of Technology as well as the personnel at the power plant were critical of Höglunds’ view.

Speaking to BBC News, SKI spokesman Anders Bredfell said that the International Atomic Energy Agency (IAEA) was informed of the incident as required and that the incident classes as a ‘2’ in the 0-7 scale used by the IAEA to assess the severity of the incident.

Another reactor in Forsmark and a fifth at Ringhals nuclear power plant have been offline due to planned maintenance work. With five of its ten reactors down, Sweden’s power generation capacity is down by almost a fifth.

The environmental group Greenpeace called on the government to shut down all reactors and probe whether the fault was a generic one. The Green Party has called for an independent investigation of the incident. Sweden is scheduled to retire all its nuclear power plants in the next few decades, as decided by a referendum in 1980.

Cindy Sheehan, an Iraq War protester, was arrested inside the Rayburn Building in Washington, D.C. in United States along with 45 to 50 other protesters for disorderly conduct on Monday.

“The Democrats will not hold this administration accountable, so we have to hold the Democrats accountable. And I for one am going to step up to the plate and run against Nancy Pelosi,” said Sheehan during her protest inside the capitol.

Sheehan and the other protesters were at the offices of Rep. John Conyers Jr. who is the House Judiciary Committee chairman, demanding that President George W. Bush and Vice President Dick Cheney be impeached. Conyers would be the politician who would start impeachment hearings.

Sheehan then said she would run against Nancy Pelosi, who is the Speaker of the House of Representatives, in the next election for her seat in the House representing the state of California.

“If Nancy Pelosi doesn’t do her constitutionally mandated job by midnight tonight, tomorrow I will announce that I’m going to run against her. Not only am I going to run against her, but I will beat her. Impeachment is not a fringe movement, it is mandated in our Constitution. Nancy Pelosi had no authority to take it off the table,” added Sheehan.

Pelosi’s Press Secretary Brenden Daly says Pelosi is working hard to make sure that the right steps are taken in Iraq.

“The speaker is focused on changing course in Iraq by bringing our troops home safely and soon and refocusing our effort on protecting Americans from terrorism, holding the Bush administration accountable and setting a ‘New Direction for America,'” said Daly.

Sheehan became an anti-war protester after her son, Casey Sheehan, was killed while fighting in the Iraq War on April 4, 2004 at the age of 24. Earlier this year, on Memorial Day, she announced her resignation as “the ‘face’ of the American anti-war movement” on a personal web journal page published by the Daily Kos.

NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.
