calving

Large calving events of the PG [Petermann Glacier] floating ice tongue in 2010 and 2012 (Johannessen et al., 2013; Rückamp et al., 2019) were associated with a 10 % acceleration of the glacier (Rückamp et al., 2019).

description

The glacier of Petermann Fjord in Greenland that feeds ice into Hall Basin.

drainage of Greenland Ice Sheet

One such glacier is Petermann Glacier (PG), draining about 4 % of the Greenland Ice Sheet (GrIS) (based on area of the drainage basin; Rignot and Kanagaratnam, 2006) into Hall Basin in Nares Strait (Fig. 1).

Reverse-engineering the conditional jump circuitry in the 8086 processor (righto.com) Intel introduced the 8086 microprocessor in 1978 and it had a huge influence on computing. I’m reverse-engineering the 8086 by examining the circuitry on its silicon die and in this blog post I take a look at how conditional jumps are implemented. Conditional jumps are an important part of any instruction set, changing the flow of execution based on a condition. Although this instruction may seem simple, it involves many parts of the CPU: the 8086 uses microcode along with special-purpose condition logic.

submarine melting

Although the calving events have attracted considerable attention, submarine melting of the ice tongue accounts for 80 % of the mass loss at PG [Petermann Glacier], making it particularly sensitive to ice–ocean interactions (Cai et al., 2017; Münchow et al., 2014; Rignot and Steffen, 2008; Rückamp et al., 2019).
