This is a list of ice cores drilled for scientific purposes. Note that many of these locations are on moving ice sheets, and the latitude and longitude given is as of the date of drilling.
^ abNot included in MacKinnon's 1980 catalogue.[6] Ueda & Talalay make it clear that a coring drill was used for this hole but not whether a core was retrieved.[4]
^Ueda and Talalay (2007) mention two test holes of 35 m each, but do not say whether cores were retrieved, though the drill was able to recover cores.[13]
^Hole 1 was drilled to 952 m between 1969 and 1972. An offset hole, 1-bis, was started at 30 m down hole 1 in 1972, and reached 780 m the following year. Another offset hole, 1-2bis, was begun at 307 m in hole 1-bis, and reached 905 m.[25]
^ abDrilled along the traverse from Mirny to Vostok.[26]
^The hole was drilled in 1971 to 108 m, and then extended to 224 m in between 1974 and 1976. An offset hole, 2-bis, was begun in 1976, but the drill got stuck after only a few runs; the additional depth drilled was not recorded and Vasiliev does not report whether any cores were recovered.[27]
^The drill stuck at 142 m, and the hole was re-entered at 107 m in an attempt to detach the stuck drill, eventually reaching 145 m on this attempt.[19]
^MacKinnon's 1980 catalogue includes a 1974-1975 Novolazarevskaya core at 70°46′S11°50′E / 70.767°S 11.833°E / -70.767; 11.833 which is not mentioned in other sources, but it does not include this 374 m core, so the two seem to be the same despite the slight differences in coordinates and depth.[31][32]
^Bentley & Koci give the depth of this hole as 412 m.[31]
^Begun in 1976, this hole reached 721 m during the 1978-1979 drilling season. A new offset hole was accidentally started at 500 m while reaming, and the new hole reached 750 m.[38]
^MacKinnon's 1980 catalogue gives the altitude as c. 500 m.[6]
^MacKinnon (1980) lists two cores in the 1977/1978 season, at c. 64°20′S57°30′W / 64.333°S 57.500°W / -64.333; -57.500 and c. 1628 m altitude,[18] but Aristarain (1981), the paper that describes these cores, only lists one core, from December 1977, as given here.[40]
^Gillet et al. give a depth of 140 meters for this core, but it appears they are only referring to the depth attained with the first drill used.[43]
^Hole 3G was extended by offset holes twice; the extensions, labelled 3G-1 and 3G-2, are treated here as part of a single core. Hole 3G-1 was begun at 1500 m, after 3G reached 1580 m depth; and hole 3G-2 was begun at 1969 m, after 3G-1 had reached 2083 m depth.[45]
^ abCoordinates estimated from map in Thwaites et al. (1984).[46]
^Hole 4G reached 279 m in 1983. In 1984 an offset hole, 4G-1, was begun at 120 m, and extended to 752 m by 1986. A second offset hole, 4G-2, was begun at 159 m in 4G-1, and reached 2546 m in 1989.[48]
^ abcThompson et al. list six cores obtained on the Dyer Plateau but do not give exact locations or altitudes. They give the plateau's coordinates as 70°40′16″S64°52′30″W / 70.67111°S 64.87500°W / -70.67111; -64.87500, with altitude 2002 m, and then say that in 1988–1989 "two ice cores were drilled to a depth of 108 m at a location 6 km west of the divide. In 1989–90, two cores were recovered 1 m apart on the crest of the Dyer Plateau (core 1 — 233.8 m and core 2 — 235.2 m) and two 50 m cores were drilled 4 km east of the divide".[52] Peel et al. list one core for 1988-1989, at 104 m, which is presumably one of the 108 m cores listed by Thompson et al.[42]
^Drilling took place in 1990-1993, 1995-1998, and 2005-2006. Hole 5G reached 2259 m; in 1992 an offset hole,
5G-1, was begun, reaching 3650 m in 2006.[54]
^Zagorodnov et al. list this core along with two of the Abramov Glacier cores as all having the same altitude, 4400 m. MacKinnon gives the lower altitude.[39][65]
^ abcNot included in MacKinnon's 1980 catalog.[72]
^ abcMacKinnon's 1980 catalogue lists three 60 m cores in 1968.[66] Gillet et al. do not explicitly list all the cores, but say that one of the 1968 cores was 67 m, and there was a 72 m core in 1969.
This list assumes these are two of the cores on MacKinnon's list.[28]
^It is not clear from the source whether these include any of the cores listed above.[39]
