Oil  spreading north-east from the leaking Deepwater Horizon well in the Gulf of Mexico

As many as four leaks have been detected in the Deepwater Horizon well cap in the Gulf of Mexico, according to live footage shot by one of BP’s ROVs (Remote Operated Vehicles). The leaks were detected early this morning, just after 4:00 (EDT).

The HOS SUPER H ROV 1 made the discovery while performing an “integrity survey” of the well and well cap. It recorded what appears to be a thin metal pipe lining the outside of the oil cap. Four small leaks of what appear to oil bubbles were detected during this survey. The first appears just after the elbow connecting the pipe to the two green pipes. The second can be seen through the hole of the large metal ring. The third is seen just to the right of the metal ring.

It is not yet known what the pipe carries or what it connects to. It is also not yet clear if all leaks are from the pipe, or leaking from the well. BP confirmed the leaks and told Wikinews in a phone call to their Houston, Texas press office, there is a “small leak” releasing hydrates consisting of gases and oil. They are “studying the issue” and are prepared to fix the pipe if it becomes an issue. Live camera feeds show hydrocarbons building up as the oil and gas leak from the pipe.

On July 18, ROV cameras showed bubbles coming from the base of well. BP said it would test the bubbles to determine what they are and as of Sunday, COO of BP Doug Suttles says the bubbles are not methane, but further tests are being conducted. “If you can imagine, it is not an easy operation to collect those bubbles so that they can be tested to see what their make-up is.”

Yesterday an unnamed United States official told the Associated Press that there was “seepage” coming from the area at the bottom of the Deepwater well head. The official said the seepage and methane gas were discovered near the Deepwater well head, but did not specify an exact location. Admiral Thad Allen, a former US Coast Guard admiral who is overseeing the spill efforts for the US government said yesterday in a letter to BP that ROVs “detected seep a distance from the well and undetermined anomalies at the well head.” So far there is no word what those substances are, but BP says the bubbles detected on July 18 are not of a hydrocarbon nature.

“When seeps are detected, you are directed to marshal resources, quickly investigate, and report findings to the government in no more than four hours,” said Allen in his letter to BP. During a press conference today, Allen confirmed seepage about 3km from the well point. He could not specify whether the seep was related to the capping of the well or if it is naturally occurring.

On June 13 the Viking Poseidon ROV (Remote Operated Vehicle) 1 recorded oil and methane seeping from the seafloor at around 2:48 a.m.. The ROV monitors the seep for a minute and even gets covered in a plume of oil and sand before it moved on to the next spot. Smaller eruptions were seen as the ROV traveled. After an investigation, Wikinews determined that the seepage was located just over 50 feet from the Deepwater leak point. BP has denied that any oil or methane gas is leaking from the sea floor. On July 16, Kent Wells, the senior vice president of the company, said on their official Twitter page that “4 ROVs using sonar scanning [are] looking for anomalies in seabed floor. No indications any oil or gas escaping.”

BP issued a press release earlier this morning, but did not state information regarding any leaks or seepage from the well. BP did say that the well cap “measured at approximately 6,792 pounds per square inch and continues to rise slowly.”

The Deepwater Horizon oil spill started on April 20 after an explosion on the rig. Efforts to put out the fire failed and the rig subsequently sank to the bottom of the Gulf. On April 22, an oil slick appeared on the surface of the Gulf. BP capped the leaking well on July 13 which effectively stopped oil from leaking into the Gulf. The company has been running a pressure integrity test on the 150,000 pound cap since it stopped the flow of oil. BP hopes for the well’s pressure to rise to or above 7,500 PSI. As of Saturday morning the well’s pressure was just above 6,700 PSI. BP fears anything lower than the expected PSI could mean a leak in the cap or elsewhere, such as oil or methane seeping up from the seafloor.

A person has died after being involved in a collision between a bus and a bicycle in Hampshire in the south of England, United Kingdom. The woman, who has not been publicly identified, was cycling in the seaside resort of Southsea when a number 700 Stagecoach single-decker bus, which was travelling from Brighton to Southsea, collided with her bicycle at approximately 1315 BST (1215 UTC) on Saturday. A helicopter transported the woman to Southampton General Hospital, where she died at approximately 1630 BST (1530 UTC) on the same day.

None of the occupants of the bus were injured. The 53-year-old bus driver has now been arrested on suspicion of causing death by dangerous driving. Hampshire Constabulary is requesting any witnesses to the accident to contact them. PC Phil Hunt also mentioned: “We are also trying to trace the passengers, who left the scene before we could speak to them.”

The road traffic accident occurred in an area where Portsmouth City Council had been intending to place a new cycle route, but the plans to do so were cancelled last week. The plans, which would have cost £250,000 (US$382,373, 296,481, A$441,126), were said to have been cancelled due to financial difficulties.

Portsmouth Cycle Forum vice chair Jon Spencer has stated: “Sadly, we’ve had to wait less than a week for a brutal illustration of why we need this cycle route.” The vice chair of the local cycling group continued: “The road at Clarence Pier is very narrow, very crowded by parked cars and very busy. It is the most popular part of the seafront but at the moment it is a no-go area for cyclists. The city council are obviously happy for this to remain the case.”

—John Holland

John Holland, the chair of the Forum, wrote on PompeyBUG, a local cycling Internet forum: “Portsmouth Cycle Forum is very sad to learn of the death in a road accident of a woman cyclist at Clarence Esplanade on Saturday 17 July. Our thoughts lie with her family and friends to whom send our deepest condolences. The cyclist was involved in collision with a bus in the vicinity of Pier Road and Clarence Esplanade, close to Clarence Pier.

“This terrible accident is yet another reminder that large vehicles, busy traffic and cyclists are not a happy mix. Whilst it will be some time before the details are made public, we urge the Portsmouth City Council to press ahead with making this section of our seafront much safer and calmer for all. Almost exactly one year ago, a cyclist was seriously injured Clarence Esplanade when a car reversed blindly from a parking bay into the road.

“Portsmouth City Council is on the verge of postponing Phase 2 of the Southsea Seafront Cycle Route. Had this been in place yesterday then this awful incident might have been avoided. We urge councillors to think again. A safe and segregated cycle route can be built – one which doesn’t loose any car parking, one which doesn’t stop people looking out to sea from their cars, one which doesn’t involve cycling on the promenade. We will be pushing hard for this – we don’t want any more injuries and fatalities on our seafront roads.”

Oil slick in the Gulf of Mexico seen from space on June 22.
Image: Wikimedia Commons.

After an investigation, Wikinews has learned that oil spewing from a rupture in the seafloor of the Gulf of Mexico on June 13 was 50 to 60 feet from the Deepwater Horizon leak.

A nearly four and a half minute video posted on YouTube on June 13 was from the Viking Poseidon ROV (Remote Operated Vehicle) 1. It shows oil and methane leaking from the seafloor at around 2:48 a.m. on June 13. The ROV monitors the leak for a minute and even gets covered in a plume of oil and sand before it moved on to the next spot. Smaller eruptions were seen as the ROV traveled, making the leak locations vary from 50 to 60 feet from the damaged well.

Until now, there was no way to determine the location of the ROVs in relation to the previously leaking Deepwater Horizon well. Alexander Higgins, an independent computer programmer, developed the ‘Gulf Oil Spill ROV UTM Distance Calculator.’ Using the coordinates for the location of the Deepwater Horizon, and the location of the Viking Poseidon on June 13, Wikinews was able to determine that the first rupture and leak was approximately 50.45 feet from the leaking well or “21.56 feet [n]orth and 45.61 feet [w]est” of the Deepwater leak point.

Higgins told Wikinews how he created the calculator, and says it is “very accurate,” but that the tool would “not give you accurate measurements over a large distance, e.g. from the well head to New Orleans.”

“This tool was created using java script that uses basic Pythagorean theorem (A^2 + B^2 = C^2) to calculate the distance between two points. The distance is simply \sqrt{(N_1 - N_2)^2 + (E_1 - E_2)^2 }. ROV coordinates match the location within a few feet when looking at the well because obviously the ROV can not be over the exact center because that is where the BOP is,” said Higgins.

BP, who owned and operated the Deepwater Horizon, has denied that any oil or methane gas is leaking from the sea floor. On July 16, Kent Wells, the senior vice president of BP, said on their official Twitter page that “4 ROVs using sonar scanning [are] looking for anomalies in seabed floor. No indications any oil or gas escaping.” Seismic tests were conducted on July 16; Admiral Thad Allen of the United States Coast Guard said that “no anomalies” were found, but also that the tests were “not comprehensive.”

On Sunday, Wikinews contacted BP, who authenticated the video, and asked if any ROVs were sent back to the crack and leak location on June 13 for further investigation. According to their office in London, England, they “sent ROVs to investigate and monitor that and no further signs of oil or gas were found.” They also stated that they “have continued to monitor” and “have also carried out seismic surveys. Nothing found to give concern.” Wikinews also asked if they could confirm the location of the leak and crack, but no response was given.

However, on July 18, the Associated Press reported that there was “seepage” coming from the area at the bottom of the Deepwater well head. For the past two days, ROV cameras showed bubbles coming from the base of well. BP said it would test the bubbles to determine what they are and as of Sunday, COO of BP Doug Suttles says the bubbles are not methane, but further tests are being conducted. “If you can imagine, it is not an easy operation to collect those bubbles so that they can be tested to see what their make-up is.”

Since the June 13 video surfaced, other videos have been posted to YouTube allegedly showing some of the ROVs being tossed around by large amounts of oil seeping through the seafloor. One video showed an alleged eruption spraying oil and debris around the BOA DEEP C 2 ROV before it was tossed from side to side. It then immediately retreated to the surface. Some of the cracks on ocean floors, where oil has leaked from, have occurred naturally. One such oil spill in California in 2005 was the result of a naturally occurring crack in the floor of the Pacific Ocean. Some of those cracks can cause oil to leak through at a rate as high as 5,000 gallons a day, with most of the oil not even reaching the water’s surface. In the Gulf of Mexico, oil leaks through natural cracks at a rate several times less than leaked from the Deepwater well.

“The Deepwater Horizon site releases 3 to 12 times the oil per day compared to that released by natural seeps across the entire Gulf of Mexico. By May 30, the Deepwater Horizon site had released between 468,000 and 741,000 barrels of oil, compared to 60,000 to 150,000 barrels from natural seeps across the entire Gulf of Mexico over the same 39 day period,” said Cutler Cleveland, a Boston University professor at the university’s Department of Geography and Environment.

The Deepwater Horizon oil spill started on April 20 after an explosion on the rig. Efforts to put out the fire failed and the rig subsequently sank to the bottom of the Gulf. On April 22, an oil slick appeared on the surface of the Gulf. BP capped the leaking well on July 13 which effectively stopped oil from leaking into the Gulf. The company has been running a pressure integrity test on the 150,000 pound cap for 48 hours. Earlier on July 17, they announced the test would continue for another day. BP hopes for the well’s pressure to rise to or above 7,500 PSI. As of Saturday morning the well’s pressure was just above 6,700 PSI. BP fears anything lower than the expected PSI could mean a leak in the cap or elsewhere, such as oil or methane seeping up from the seafloor.

“We are feeling more comfortable we have integrity. We will keep monitoring and make the decisions as we go forward. The longer the test goes the more confidence we have in it,” said Allen.

A train crash in India at around 0200 local time Monday (2030 UTC on Sunday) has killed at least 40 people and injured at least another 100. The crash occurred in the town of Sainthia, which is located in eastern India. Initial reports say that one passenger train collided with another that was waiting at a station, but the exact cause is not known.

The lowest estimate of the death toll is around 40 dead, and Indian media has reported that there are as many as 100 dead and 150 people injured. The incident has prompted a major rescue operation, and senior government officials are en route to the site of the incident.

The region’s Superintendent of Police, Humayun Kabir, said that “[c]asualties have taken place. I cannot give any number now. Rescue work has begun.” A local railroad official said that “[t]he people who have lost their lives were travelling in unreserved coaches. We do not have their names and any vital information about them to inform their relatives.” The state-run Indian railway system has a poor safety record, with several hundred incidents a year taking place, and this crash is the third major one in the past decade.

On Sunday, gunmen stormed a party in Torreon, a city in the north of Mexico. According to local authorities, at least eighteen people were injured, and seventeen died. The victims have not yet been identified, but several were young and some were women.

According to a statement from the Coahuila state Attorney General’s office, the gunmen arrived in several cars and opened fire without saying a word. This happened after a similar shooting last month, in which eight people were killed at a bar, in the same city. In all of northern Mexico there are increasing reports of mass shootings at parties, bars and rehab clinics.

Investigators do not yet have any suspects and do not know the motive, but believe that the shooting may be linked to Mexico’s long-running drugs war. Police found more than 120 bullet casings at the scene, the majority of which were from .223 caliber guns.

Traralgon went within a game and percentage of ladder leader Maffra with a 118 point victory over Warragul in their round 14 Gippsland Football League match. However, 24 hours later, Maffra defeated Sale by 44 points.

The Gippsland Football League, officially the Gippsland League, is the only major Australian rules football competition in the Gippsland region, according to the Victorian Country Football League.

Warragul kicked both of its goals in the first half, still conceivably in the contest at that point thanks to Traralgon’s inaccurate seven goals and ten behinds. The hosts kicked five goals in the third quarter to extend their lead to ten goals.

At the end of the day, Traralgon won 20-13 (136) to Warragul’s 2-6 (18).

Drouin played Morwell in the other match played on Saturday. On Sunday, Maffra hosted Sale in Maffra, and Moe hosted Wonthaggi in Morwell to complete the round.
