MARC recordAnnually-averaged polar sea-ice extents during 1978-1987: northern extent decrease and southern extent oscillation (abstract) / Per Gloersen, William J. Campbell.
| Title: | Annually-averaged polar sea-ice extents during 1978-1987: northern extent decrease and southern extent oscillation (abstract) / Per Gloersen, William J. Campbell. |
| Author(s): | Gloersen, Per. Campbell, William J. |
| Date: | 1990. |
| In: | Annals of Glaciology. (1990.), Vol. 14 (1990) |
| Abstract: | 1978-87 satellite observations of global sea-ice extent were separated into Arctic and Antarctic components. Annually-averaged global extent decrease was 2.5%. Greater part of decrease was in Arctic (3.5%); small oscillation was superimposed on this with period of about 4 years and amplitude of 1%. Significantly smaller and statistically insignificant decrease of 1.2% was observed for Antarctic; three large oscillations (4%) were superimposed at periods of 3 years, in phase with El Niño events. |
