Orpissuup Tasia Glacier slowdown, SW Greenland

Tedstone et al (2015) Figure 3 illustrates the widespread velocity decline along three transects.  Pelto et al (1989) after a field campaign we mounted in 1985 and 1986 on Jakobshavns Glacier noted that the velocity was essentially the same in the summer of 1964, 1976, 1978, 1985 and 1986.  Further we observed that the agreement between surface mass-balance and volume-flux calculations, suggested that “Jakobshavns Isbrae: is almost in a state of equilibrium”. The point …
