MARC recordSea-ice extent in the Southern Ocean during the Last Glacial Maximum: another approach to the problem / Lloyd H. Burckle, Richard Mortlock.
| Title: | Sea-ice extent in the Southern Ocean during the Last Glacial Maximum: another approach to the problem / Lloyd H. Burckle, Richard Mortlock. |
| Author(s): | Burckle, Lloyd H. Mortlock, Richard. |
| Date: | 1998. |
| In: | Annals of Glaciology. (1998.), Vol. 27 (1998) |
| Abstract: | Using coherence between percentage of diatoms in surface sediments and annual sea-ice cover, able to estimate yearly concentration of sea ice to within 30%. Estimating percentage sea-ice cover during LGM for number of sediment sites from Southern Ocean finds sites not beneath open water witnessed 25-60% sea ice during LGM, while sites now beneath sea ice during half of year witnessed more than 75% sea-ice cover during LGM. |
| Notes: | Annals of Glaciology. Vol. 27 :302-304 (1998). International Symposium on Antarctica and Global Change: Interactions and Impacts, W.F. Budd (Editor), 13--18 July 1997, Hobart, Tasmania, Australia. |
