Main publication details
MARC recordA one-dimensional model of ice shelf-ocean interaction / Adrian Jenkins.
| Title: | A one-dimensional model of ice shelf-ocean interaction / Adrian Jenkins. |
| Author(s): | Jenkins, Adrian. |
| Date: | 1991. |
| In: | Journal of Geophysical Research. (1991.), Vol. 96(C11) (1991) |
| Abstract: | Dense saline waters are drawn underneath ice shelves and emerge, cooled and diluted, as plumes of ice-shelf water. Plume is treated as turbulent gravity current, initiated at inland margin by flow of fresh meltwater emerging from beneath grounded ice. Subsequent evolution of plume as it ascends along ice-shelf base of specified geometry can be simulated. Model has been applied to flowline on Ronne Ice Shelf, Antarctica, to explain observed distribution and rate of basal melting and freezing. Calculations indicate that present mean melt rate would increase from 0.6 to 2.6 m a⁻¹ if underlying water were to warm by 0.6°C. |
