Mount Erebus

Mount Erebus (/ˈɛrɪbəs/) is the second-highest volcano in Antarctica (after Mount Sidley), the highest active volcano in Antarctica, and the southernmost active volcano on Earth. It is the sixth-highest peak of an island and the second most prominent mountain in Antarctica after Mount Vinson.[4] It has a summit elevation of 3,794 metres (12,448 ft). It is located in the Ross Dependency on Ross Island, which is also home to three inactive volcanoes: Mount Terror, Mount Bird, and Mount Terra Nova.[citation needed] The mountain was named by Captain James Clark Ross in 1841 for his ship, the Erebus.[2]

On 28 November, 1979, Air New Zealand Flight 901 crashed on Mount Erebus killing all 257 people on board.

Geology and volcanology edit

Mount Erebus is the world's southernmost active volcano. It is the current eruptive centre of the Erebus hotspot. The summit contains a persistent convecting phonolitic lava lake, one of five long-lasting lava lakes on Earth. Characteristic eruptive activity consists of Strombolian eruptions from the lava lake or from one of several subsidiary vents, all within the volcano's inner crater.[5][6] The volcano is scientifically remarkable in that its relatively low-level and unusually persistent eruptive activity enables long-term volcanological study of a Strombolian eruptive system very close (hundreds of metres) to the active vents, a characteristic shared with only a few volcanoes on Earth, such as Stromboli in Italy. Scientific study of the volcano is also facilitated by its proximity to McMurdo Station (U.S.) and Scott Base (New Zealand), both sited on the same island around 35 km away.

Mount Erebus is classified as a polygenetic stratovolcano. The bottom half of the volcano is a shield and the top half is a stratocone. The composition of the current eruptive products of Erebus are anorthoclase-porphyritic tephritic phonolite and phonolite, which are the bulk of exposed lava flow on the volcano. The oldest eruptive products consist of relatively undifferentiated and nonviscous basanite lavas that form the low broad platform shield of Erebus. Slightly younger basanite and phonotephrite lavas crop out on Fang Ridge – an eroded remnant of an early Erebus volcano – and at other isolated locations on the flanks of Erebus. Erebus is the world's only presently erupting phonolite volcano.[7]

Lava flows of more viscous phonotephrite and trachyte erupted after the basanite. The upper slopes of Mount Erebus are dominated by steeply dipping (about 30°) tephritic phonolite lava flows with large-scale flow levees. A conspicuous break in slope around 3,200 m ASL calls attention to a summit plateau representing a caldera. The summit caldera was created by an explosive VEI-6 eruption that occurred 18,000 ± 7,000 years ago.[8] It is filled with small volume tephritic phonolite and phonolite lava flows. In the center of the summit caldera is a small, steep-sided cone composed primarily of decomposed lava bombs and a large deposit of anorthoclase crystals known as Erebus crystals. The active lava lake in this summit cone undergoes continuous degassing.

Following studies conducted in the early 1990s, it was found that Mount Erebus releases small amounts of gold crystals in the gases produced from the volcano; these crystals range in size from 20 to 60 micrometres. It is estimated that around 80 grams of gold are released by the volcano in this manner each day.[9]

Researchers spent more than three months during the 2007–08 field season installing an atypically dense array of seismometers around Mount Erebus to listen to waves of energy generated by small, controlled blasts from explosives they buried along its flanks and perimeter, and to record scattered seismic signals generated by lava lake eruptions and local ice quakes. By studying the refracted and scattered seismic waves, the scientists produced an image of the uppermost (top few km) of the volcano to understand the geometry of its "plumbing" and how the magma rises to the lava lake. [10][11] These results demonstrated a complex upper-volcano conduit system with appreciable upper-volcano magma storage to the northwest of the lava lake at depths hundreds of meters below the surface.

Ice fumaroles edit

Mount Erebus is notable for its numerous ice fumaroles – ice towers that form around gases that escape from vents in the surface.[12] The ice caves associated with the fumaroles are dark, in polar alpine environments starved in organics and with oxygenated hydrothermal circulation in highly reducing host rock. The life is sparse, mainly bacteria and fungi. This makes it of special interest for studying oligotrophs – organisms that can survive on minimal amounts of resources.

The caves on Erebus are of special interest for astrobiology,[13] as most surface caves are influenced by human activities, or by organics from the surface brought in by animals (e.g. bats and birds) or ground water.[14] The caves at Erebus are at high altitude, yet accessible for study. Some of the caves can reach temperatures of 25 degrees Celsius (77 degrees Fahrenheit), and with light near the cave mouths, in some caves covered by thin overlying ice the light reach even deeper, is sufficient to sustain an ecosystem of flora and fauna consisting of moss, algae, arthropods and nematodes.[15]

They are dynamic systems that collapse and rebuild, but persist over decades. The air inside the caves has 80 to 100% humidity, and up to 3% carbon dioxide (CO2), and some carbon monoxide (CO) and hydrogen (H2), but almost no methane (CH4) or hydrogen sulfide (H2S). Many of them are completely dark, so cannot support photosynthesis. Organics can only come from the atmosphere, or from ice algae that grow on the surface in summer, which may eventually find their way into the caves through burial and melting. As a result, most micro-organisms there are chemolithoautotrophic i.e. microbes that get all of their energy from chemical reactions with the rocks, and that do not depend on any other lifeforms to survive. The organisms survive using CO2 fixation and some may use CO oxidization for the metabolism. The main types of microbe found there are Chloroflexota and Acidobacteriota.[16][17] In 2019, the Marsden Fund granted nearly NZ$1 million to the University of Waikato and the University of Canterbury to study the micro-organisms in the geothermal fumaroles.[18]

History edit

Discovery and naming edit

Mount Erebus was discovered on 27 January 1841 (and observed to be in eruption),[19] by polar explorer Sir James Clark Ross on his Antarctic expedition, who named it and its companion, Mount Terror, after his ships, HMS Erebus and HMS Terror (which were later used and lost by Sir John Franklin on his disastrous Arctic expedition). Present with Ross on HMS Erebus was the young Joseph Hooker, future president of the Royal Society and close friend of Charles Darwin. Erebus is a dark region in Hades in Greek mythology, personified as the Ancient Greek primordial deity of darkness, the son of Chaos.[20]

Historic sites edit

The mountain was surveyed in December 1912 by a science party from Robert Falcon Scott's Terra Nova expedition, who also collected geological samples. Two of the camp sites they used have been recognised for their historic significance:

  • Upper “Summit Camp” site (HSM 89) consists of part of a circle of rocks, which were probably used to weight the tent valances.
  • Lower “Camp E” site (HSM 90) consists of a slightly elevated area of gravel, as well as some aligned rocks, which may have been used to weight the tent valances.

They have been designated historic sites or monuments following a proposal by the United Kingdom, New Zealand, and the United States to the Antarctic Treaty Consultative Meeting.[21]

Climbing edit

Mount Erebus' summit crater rim was first achieved by members of Sir Ernest Shackleton's party; Professor Edgeworth David, Sir Douglas Mawson, Dr Alister Mackay, Jameson Adams, Dr Eric Marshall and Phillip Brocklehurst (who did not reach the summit), in 1908. Its first known solo ascent and the first winter ascent was accomplished by British mountaineer Roger Mear on 7 June 1985, a member of the "In the Footsteps of Scott" expedition.[22] On 19–20 January 1991, Charles J. Blackmer, an iron-worker for many years at McMurdo Station and the South Pole, accomplished a solo ascent in about 17 hours completely unsupported, by snow mobile and on foot.[23][24]

Robotic exploration edit

In 1992, the inside of the volcano was explored by Dante I, an eight legged tethered robotic explorer.[25] Dante was designed to acquire gas samples from the magma lake inside the inner crater of Mount Erebus to understand the chemistry better through the use of the on-board gas chromatograph, as well as measuring the temperature inside the volcano and the radioactivity of the materials present in such volcanoes. Dante successfully scaled a significant portion of the crater before technical difficulties emerged with the fibre-optic cable used for communications between the walker and base station. Since Dante had not yet reached the bottom of the crater, no data of volcanic significance was recorded. The expedition proved to be highly successful in terms of robotic and computer science, and was possibly the first expedition by a robotic platform to Antarctica.

Air New Zealand Flight 901 edit

 
Wreckage of Flight 901

Air New Zealand Flight 901 was a scheduled sightseeing service from Auckland Airport in New Zealand to Antarctica and return with a scheduled stop at Christchurch Airport to refuel before returning to Auckland.[26] The Air New Zealand flyover service, for the purposes of Antarctic sightseeing, was operated with McDonnell Douglas DC-10-30 aircraft and began in February 1977. The flight crashed into Mount Erebus on November 28, 1979, killing all 257 people on board. Passenger photographs taken seconds before the collision ruled out the "flying in a cloud" theory, showing perfectly clear visibility well beneath the cloud base, with landmarks 13 miles (21 km) to the left and 10 miles (16 km) to the right of the aircraft visible.[27] The mountain directly ahead was lit by sunlight shining from directly behind the aircraft through the cloud deck above, resulting in a lack of shadows that made Mount Erebus effectively invisible against the overcast sky beyond in a classic whiteout (more accurately, "flat-light") phenomenon.[28] Further investigation of the crash showed a navigational error in flight documentation by Air New Zealand and a cover-up that resulted in about $100 million in lawsuits. Air New Zealand discontinued its flyovers of Antarctica. Its final flight was on February 17, 1980. During the Antarctic summer, snow melt on the flanks of Mount Erebus continually reveals debris from the crash that is visible from the air.[26]

Anorthoclase crystal 45 mm long from Mount Erebus Mount Erebus is the world s southernmost active volcano It is the current eruptive centre of the Erebus hotspot The summit contains a persistent convecting phonolitic lava lake one of five long lasting lava lakes on Earth Characteristic eruptive activity consists of Strombolian eruptions from the lava lake or from one of several subsidiary vents all within the volcano s inner crater 5 6 The volcano is scientifically remarkable in that its relatively low level and unusually persistent eruptive activity enables long term volcanological study of a Strombolian eruptive system very close hundreds of metres to the active vents a characteristic shared with only a few volcanoes on Earth such as Stromboli in Italy Scientific study of the volcano is also facilitated by its proximity to McMurdo Station U S and Scott Base New Zealand both sited on the same island around 35 km away Mount Erebus is classified as a polygenetic stratovolcano The bottom half of the volcano is a shield and the top half is a stratocone The composition of the current eruptive products of Erebus are anorthoclase porphyritic tephritic phonolite and phonolite which are the bulk of exposed lava flow on the volcano The oldest eruptive products consist of relatively undifferentiated and nonviscous basanite lavas that form the low broad platform shield of Erebus Slightly younger basanite and phonotephrite lavas crop out on Fang Ridge an eroded remnant of an early Erebus volcano and at other isolated locations on the flanks of Erebus Erebus is the world s only presently erupting phonolite volcano 7 Lava flows of more viscous phonotephrite and trachyte erupted after the basanite The upper slopes of Mount Erebus are dominated by steeply dipping about 30 tephritic phonolite lava flows with large scale flow levees A conspicuous break in slope around 3 200 m ASL calls attention to a summit plateau representing a caldera The summit caldera was created by an explosive VEI 6 eruption that occurred 18 000 7 000 years ago 8 It is filled with small volume tephritic phonolite and phonolite lava flows In the center of the summit caldera is a small steep sided cone composed primarily of decomposed lava bombs and a large deposit of anorthoclase crystals known as Erebus crystals The active lava lake in this summit cone undergoes continuous degassing Following studies conducted in the early 1990s it was found that Mount Erebus releases small amounts of gold crystals in the gases produced from the volcano these crystals range in size from 20 to 60 micrometres It is estimated that around 80 grams of gold are released by the volcano in this manner each day 9 Researchers spent more than three months during the 2007 08 field season installing an atypically dense array of seismometers around Mount Erebus to listen to waves of energy generated by small controlled blasts from explosives they buried along its flanks and perimeter and to record scattered seismic signals generated by lava lake eruptions and local ice quakes By studying the refracted and scattered seismic waves the scientists produced an image of the uppermost top few km of the volcano to understand the geometry of its plumbing and how the magma rises to the lava lake 10 11 These results demonstrated a complex upper volcano conduit system with appreciable upper volcano magma storage to the northwest of the lava lake at depths hundreds of meters below the surface Ice fumaroles editMount Erebus is notable for its numerous ice fumaroles ice towers that form around gases that escape from vents in the surface 12 The ice caves associated with the fumaroles are dark in polar alpine environments starved in organics and with oxygenated hydrothermal circulation in highly reducing host rock The life is sparse mainly bacteria and fungi This makes it of special interest for studying oligotrophs organisms that can survive on minimal amounts of resources The caves on Erebus are of special interest for astrobiology 13 as most surface caves are influenced by human activities or by organics from the surface brought in by animals e g bats and birds or ground water 14 The caves at Erebus are at high altitude yet accessible for study Some of the caves can reach temperatures of 25 degrees Celsius 77 degrees Fahrenheit and with light near the cave mouths in some caves covered by thin overlying ice the light reach even deeper is sufficient to sustain an ecosystem of flora and fauna consisting of moss algae arthropods and nematodes 15 They are dynamic systems that collapse and rebuild but persist over decades The air inside the caves has 80 to 100 humidity and up to 3 carbon dioxide CO2 and some carbon monoxide CO and hydrogen H2 but almost no methane CH4 or hydrogen sulfide H2S Many of them are completely dark so cannot support photosynthesis Organics can only come from the atmosphere or from ice algae that grow on the surface in summer which may eventually find their way into the caves through burial and melting As a result most micro organisms there are chemolithoautotrophic i e microbes that get all of their energy from chemical reactions with the rocks and that do not depend on any other lifeforms to survive The organisms survive using CO2 fixation and some may use CO oxidization for the metabolism The main types of microbe found there are Chloroflexota and Acidobacteriota 16 17 In 2019 the Marsden Fund granted nearly NZ 1 million to the University of Waikato and the University of Canterbury to study the micro organisms in the geothermal fumaroles 18 History editDiscovery and naming edit Mount Erebus was discovered on 27 January 1841 and observed to be in eruption 19 by polar explorer Sir James Clark Ross on his Antarctic expedition who named it and its companion Mount Terror after his ships HMS Erebus and HMS Terror which were later used and lost by Sir John Franklin on his disastrous Arctic expedition Present with Ross on HMS Erebus was the young Joseph Hooker future president of the Royal Society and close friend of Charles Darwin Erebus is a dark region in Hades in Greek mythology personified as the Ancient Greek primordial deity of darkness the son of Chaos 20 Historic sites edit nbsp Photograph of Mount Erebus and Adelie penguins taken by the Terra Nova expedition in 1913 The mountain was surveyed in December 1912 by a science party from Robert Falcon Scott s Terra Nova expedition who also collected geological samples Two of the camp sites they used have been recognised for their historic significance Upper Summit Camp site HSM 89 consists of part of a circle of rocks which were probably used to weight the tent valances Lower Camp E site HSM 90 consists of a slightly elevated area of gravel as well as some aligned rocks which may have been used to weight the tent valances They have been designated historic sites or monuments following a proposal by the United Kingdom New Zealand and the United States to the Antarctic Treaty Consultative Meeting 21 Climbing edit Main article Nimrod Expedition Mount Erebus summit crater rim was first achieved by members of Sir Ernest Shackleton s party Professor Edgeworth David Sir Douglas Mawson Dr Alister Mackay Jameson Adams Dr Eric Marshall and Phillip Brocklehurst who did not reach the summit in 1908 Its first known solo ascent and the first winter ascent was accomplished by British mountaineer Roger Mear on 7 June 1985 a member of the In the Footsteps of Scott expedition 22 On 19 20 January 1991 Charles J Blackmer an iron worker for many years at McMurdo Station and the South Pole accomplished a solo ascent in about 17 hours completely unsupported by snow mobile and on foot 23 24 nbsp Aerial view of Mount Erebus craters Robotic exploration edit In 1992 the inside of the volcano was explored by Dante I an eight legged tethered robotic explorer 25 Dante was designed to acquire gas samples from the magma lake inside the inner crater of Mount Erebus to understand the chemistry better through the use of the on board gas chromatograph as well as measuring the temperature inside the volcano and the radioactivity of the materials present in such volcanoes Dante successfully scaled a significant portion of the crater before technical difficulties emerged with the fibre optic cable used for communications between the walker and base station Since Dante had not yet reached the bottom of the crater no data of volcanic significance was recorded The expedition proved to be highly successful in terms of robotic and computer science and was possibly the first expedition by a robotic platform to Antarctica Air New Zealand Flight 901 edit nbsp Wreckage of Flight 901 Main article Mount Erebus disaster Air New Zealand Flight 901 was a scheduled sightseeing service from Auckland Airport in New Zealand to Antarctica and return with a scheduled stop at Christchurch Airport to refuel before returning to Auckland 26 The Air New Zealand flyover service for the purposes of Antarctic sightseeing was operated with McDonnell Douglas DC 10 30 aircraft and began in February 1977 The flight crashed into Mount Erebus on November 28 1979 killing all 257 people on board Passenger photographs taken seconds before the collision ruled out the flying in a cloud theory showing perfectly clear visibility well beneath the cloud base with landmarks 13 miles 21 km to the left and 10 miles 16 km to the right of the aircraft visible 27 The mountain directly ahead was lit by sunlight shining from directly behind the aircraft through the cloud deck above resulting in a lack of shadows that made Mount Erebus effectively invisible against the overcast sky beyond in a classic whiteout more accurately flat light phenomenon 28 Further investigation of the crash showed a navigational error in flight documentation by Air New Zealand and a cover up that resulted in about 100 million in lawsuits Air New Zealand discontinued its flyovers of Antarctica Its final flight was on February 17 1980 During the Antarctic summer snow melt on the flanks of Mount Erebus continually reveals debris from the crash that is visible from the air 26 Craters edit nbsp Satellite picture of Mount Erebus showing glow from its persistent lava lake Main Crater edit 77 31 43 S 167 09 35 E 77 528689 S 167 159805 E 77 528689 167
