Talk:List of ice cores

Notes

The altitude of Camp Century appears to be 6180 feet but I can't find a source for it. Mike Christie (talk - contribs - library) 00:49, 6 April 2017 (UTC)

Also Dansgaard, in Frozen Annals, mentions (p. 31-32) some EPF cores in the late 1950s that don't seem to be mentioned elsewhere; they were mostly lost in a fire. Mike Christie (talk - contribs - library) 00:10, 7 April 2017 (UTC)

• Was there three site A cores drilled in 1985. Alley&Koci1988 mentions two 100mm ice cores (PICO). Clausen et al. 1988 mentions one slightly longer one that is 75mm (GISP), JPSteffensen has first hand memories of that. The positions are 10km apart, with the best positions in Clausen.

Additional cores pending more data before adding

• Banta & McConnell (2007), "Annual accumulation over recent centuries..." refers to D2, D3, D4, D5, Katie, Sandy, and Summit99. They give the coords but not the drill depths for each one; the depths range from 30-148m so this is not the deep Summit core from GRIP. They cite Burkhart, J. F., M. Hutterli, R. C. Bales, and J. R. McConnell (2004), "Seasonal accumulation timing and preservation of nitrate in firn at Summit, Greenland", J. Geophys. Res., 109, D19302, doi:10.1029/2004JD004658 and McConnell, J. R., G. W.

Lett., 29(23), 2130, doi:10.1029/2002GL016016, but it's not clear if these give more details on the cores themselves.

• Ice Core Paleoclimatology Research Group lists core data; I think the only one not in the article is the Bruce Plateau one. This page has data; this paper may have more details.
• The ice core article lists several Greenland cores not included yet:
  • Crête 1984-5 (8 cores). Source given redirects to the NOAA ice core data page.
  • Hans Tausen 1977. Currently the article includes 1975 and 1976, with cores of 60 m and 50 m, but there seems to be a 325 m core from 1977. The source given is Dansgaard's Frozen Annals, but I can't find it there.
  • Camp III; lists a 1978 80 m core. No source.

Langway & Herron (1977), "Polar ice core analysis", Antarctic Journal, mentions

• J-9 - depth not clear, at least 156 m. Part of RISP (Ross Ice Shelf Project); 82 22 S, 168 40 W
• C-7 - 78 20 S, 179 51 E, 50 m, drilled by Herron, Chiang and Cragin
• Roosevelt Island - 79 22 S, 161 40 W, also Herron, Chiang and Cragin.

For Dolleman Island 1994/5, Abram cites asteur, E. C., R. Mulvaney, D. A. Peel, E. S. Saltzman, and P.-Y. Whung(1995), A 340 year record of biogenic sulphur from the Weddell Sea area,Antarctica, Ann. Glaciol., 21, 169 – 17.

This is actually the 1992/3 core; Abram has the date wrong. Striking. Mike Christie (talk - contribs - library) 19:42, 16 April 2017 (UTC)

For Berkner Island Abram cites Mulvaney, R., H. Oerter, D. A. Peel, W. Graf, C. Arrowsmith, E. C. Pasteur,B. Knight, C. Littot, and W. D. Miners (2002), 1000 year ice-core recordsfrom Berkner Island, Antarctica, Ann. Glaciol., 35, 45 – 51. -- Mike Christie (talk - contribs - library) 01:33, 16 April 2017 (UTC)

Dolleman Island: Peel 2004 says drill date "Jan 1986 Jan 1976", and then lower in the table says "133 m,32 m 11 m & 11 m". Since Pasteur 1995 only describes the 133 m core in 1986, I think the 32 m core must be 1976. Mike Christie (talk - contribs - library) 19:42, 16 April 2017 (UTC)

This is incorrect; per Peel et al 1988 "Stable isotope /air temperature relationships", the 133m, 32 m and one of the 11 m are Jan 1986; the other 11 m is Jan 1976. Mike Christie (talk - contribs - library) 10:50, 18 April 2017 (UTC)

More with incomplete data from Pasteur et al 1995:

• Gomez Nunakak 74 01 S 70 38 W cited to Mulvaney et al. (1992) "The ratio of MSA to non-sea-salt sulfate in Antarctic Peninsula ice cores". Tellus 44B(4) 295-303.
• Dyer Plateau 70 31 S 65 01 W also to Mulvaney et al
• Law Dome 66 30 S 113 E cited to Ivey et al 1986 "Methanesulfonate in Antarctic ice" Tellus 38B(5) 375-379.

  Ivey gives little additional information; only adding that it was part of an Australian National Antarctic Research Expedition, and that there were two cores.

Bradley 1994 cites "many shallow cores" on James Ross Island; cites Aristarain 1980, Aristarain & Delmas 1981, and Aristarain et al 1986 "Past ANtarctic Peninsuala climate deduced from an ice core isotope record" Climatic Change 8, 69-89, and Aristarain et al 1987 "Accumulation and temperature measurements on the James Ross Island ice cap" J Glaciology 33, (115) 357-62 for sources. Mike Christie (talk - contribs - library) 19:49, 16 April 2017 (UTC)

Mulvaney et al. 2002 mentions 1990 11m firn cores on Berkner, citing Wagenbach, D. and 6 others.1994. Reconnaissance of chemical and isotopic firn properties on top of Berkner Island, Antarctica. Ann. Glaciol., 20,307^312

Also Mulvaney mentions some shallow cores they drilled, and gives some details, in additional to the full cores. Mike Christie (talk - contribs - library) 02:02, 17 April 2017 (UTC)

Found Wagenbach and included those cores; he in turn cites Oerter et al. 1990 "Glaciological work at Filchner-Ronne Ice Shelves during the 1989fl990 field season" for some additional cores on Berkner Island; not sure but these might be the same ones. Mike Christie (talk - contribs - library) 00:39, 18 April 2017 (UTC)

Also need to look at "Interpretation of Glaciochemical Records from an Array of Greenland Ice Cores JR Banta - 2006 - ProQuest". Mike Christie (talk - contribs - library) 00:46, 18 April 2017 (UTC)

Mulvaney & Peel, 1988, "Anions and Cations in Ice Cores from Dolleman Island and the Palmer Land Plateau, Antarctic Peninsula" mentions a Palmer Land plateau core 47.2 m 74 1 S 70 38 W and a 10.5 m core from Dolleman Island 70 35.2 S 60 55.5 W. The latter might be one of the 1976 cores already in the table; the former is not in the list. Mike Christie (talk - contribs - library) 01:11, 18 April 2017 (UTC)

Done; the Palmer Land core is also known as Gomez. Mike Christie (talk - contribs - library) 10:58, 18 April 2017 (UTC)

Bird 1974 lists a Cape Folger core "in process" in addition to the 348 m Cape Folger core. Mike Christie (talk - contribs - library) 02:20, 19 April 2017 (UTC)

Three more papers to go through:

• Bentley & Koci (2007)
• CRREL 1984 report 84-34.
• Ueda & Talalay (2007)

-- Mike Christie (talk - contribs - library) 10:35, 19 April 2017 (UTC)

The Mirny 1965-6 hole is given in Ueda & Talalay as three holes and a total of 101 m; several citations there may give more details. Mike Christie (talk - contribs - library) 12:08, 19 April 2017 (UTC)

For the Novolazareskaya cores, Bentley and Koci cite Morev, V.A., L.N. Manevskiy, V.M. Yakovlev and V.S. Zagorodnov. 1988. Drilling with ethanol-based antifreeze in Antarctica. In Rado, C. and D. Beaudoing, eds. Ice core drilling. Proceedings of the Third International Workshop on Ice Drilling Technology, Grenoble, France, 10–14 October 1988. Grenoble, Centre National de la Recherche Scientifique. Laboratoire de Glaciologie et Ge´ophysique de l’Environnement, 110–113, and Horwath, M. and 7 others. 2006. Nivlisen, an Antarctic ice shelf in Dronning Maud Land: geodetic–glaciological results from a combined analysis of ice thickness, ice surface height and iceflow observations. J. Glaciol., 52(176), 17–30.

And Morev 1988 is also cited for the Shackleton ice shelf core in 1978/9. Mike Christie (talk - contribs - library) 19:27, 22 April 2017 (UTC)

Morev turns out to be useless for those, but he gives a little info about some other cores. The real source for the Novolazareskaya cores appears to be Korotkevich "Drilling through the ice shelf in the vicinity of Novolazarevskaya Station", but Horwath 2006 says the locations contradict other reports. Mike Christie (talk - contribs - library) 13:33, 23 April 2017 (UTC)

Bentley & Koci (2007) p. 6 list some non-core holes for Siple & Gould Coasts, and say some cores were taken in some cases, with no details. Citation is Engelhardt, H. 2004a. Ice temperature and high geothermal flux at Siple Dome, West Antarctica, from borehole measurements. J. Glaciol., 50(169), 251–256. Mike Christie (talk - contribs - library) 16:38, 23 April 2017 (UTC)

Similarly Amery Ice Shelf 2000-06 B&K list "several ice cores taken with a Caltech style hot-water corer". Cites are to four papers by Craven:

• Craven, M., A. Elcheikh, R. Brand and N. Jones. 2002. Hot water drilling on the Amery Ice Shelf – the AMISOR project. Mem., Natl. Inst. Polar Res. 56 Special Issue , 217–225.

The niclsite.xls spreadsheet lists three more GISP2 cores but gives no depth: B and C in 1989, and E in 1990. The elevation it gives, 3203, is quite different from the existing source for the main D core; I've used it for G1/G2 since I have no other source. Mike Christie (talk - contribs - library) 09:27, 25 April 2017 (UTC)

MacKinnon, P.K. (1980). "Ice Cores" World Data Center for Glaciology Report appears to be an early comprehensive list. The NSIDC lists it on their website but the link is broken; I've emailed them. Mike Christie (talk - contribs - library) 09:38, 25 April 2017 (UTC)

Suzuki, Yosio. (1984). "Light weight electro-mechanical drills" in the 1984 CRREL Ice Drilling proceedings lists several holes drilled by Japanese expeditions, with citations. Mike Christie (talk - contribs - library) 11:04, 25 April 2017 (UTC)

In the same proceedings, Jessberger and Doerr mention three holes and give names, dates, and depths (p. 49) but the location isn't clear. Mike Christie (talk - contribs - library) 23:49, 25 April 2017 (UTC)

And Bensen mentions a Mt. Wrangell core of 43.5 m total length, possibly more than one core, from 1982; the location is given on a map but with no coords. Ongoing investigations are cited. Mike Christie (talk - contribs - library) 23:53, 25 April 2017 (UTC)

Rapp, p. 110, lists EPICA, Dome F and WAIS cores without much detail; some appear to be already in the list but some are not. Mike Christie (talk - contribs - library) 20:30, 7 May 2017 (UTC)

Thompson, "Ice core evidence: Peru and China", in Bradley & Jones (2004), refers to post-1980 Quelccaya cores and a Dunde, China core that I don't have listed. Mike Christie (talk - contribs - library) 20:41, 7 May 2017 (UTC)
