324-646: A child. She grew up in the Nelson area of the South Island of New Zealand. Although she wanted to study physics and chemistry in college she was discouraged from doing so because she was a woman. However despite starting an arts degree at Canterbury University , she ultimately completed a physics degree. Rodgers worked as a science technician in the geophysics division of the Department of Scientific and Industrial Research . She became an equipment expert for

405-671: A line from Cape Royds to the crater of Mount Erebus. The cone itself is about 100 metres (330 ft) high high and is surrounded by a deep moat or ditch, caused by the sweeping action of strong winds. It was named by F. Debenham on the second ascent of Mount Erebus for F.J. Hooper, a steward of the British Antarctic Expedition, 1910-13. Hooper was one of the party making the second ascent. 77°32′26″S 166°51′02″E  /  77.540504°S 166.850438°E  / -77.540504; 166.850438 Two rock summits at about 1,500 metres (4,900 ft) high on

1134-610: Is notable for its numerous ice fumaroles – ice towers that form around gases that escape from vents in the surface. 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, as most surface caves are influenced by human activities, or by organics from

1215-514: 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

1296-418: Is the site of a slump which has occurred off the crater rim. It is also a former camp site used by summit parties. A small hut is located on the upper part of the slope. 77°31′37″S 167°08′45″E  /  77.52682°S 167.145742°E  / -77.52682; 167.145742 .

2592-406: The caves has 80 to 100% humidity, and up to 3% carbon dioxide (CO 2 ), and some carbon monoxide (CO) and hydrogen (H 2 ), but almost no methane (CH 4 ) or hydrogen sulfide (H 2 S). 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

2673-436: 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 CO 2 fixation and some may use CO oxidization for the metabolism. The main types of microbe found there are Chloroflexota and Acidobacteriota . In 2019,

3645-479: The ice-covered southwest slopes of Mount Erebus, situated 6 nautical miles (11 km; 6.9 mi) east of Cape Barne . This rock cliff was mapped by the British Antarctic Expedition under Scott, 1910-13, and identified simply as "Bold Cliff on maps resulting from that expedition. It was named Williams Cliff by the US-ACAN in 1964 to commemorate Richard T. Williams, who losi: his life when his tractor broke through

3726-611: 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. 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.
