Eurasian Ice Sheet collapse was a major source of Meltwater Pulse 1A 14,600 years ago
Brendryen, Jo; Haflidason, Haflidi; Yokoyama, Yusuke; Haaga, Kristian Agasøster; Hannisdal, Bjarte (Journal article; Peer reviewed, 2020)Rapid sea-level rise caused by the collapse of large ice sheets is a threat to human societies. In the last deglacial period, the rate of global sea-level rise peaked at more than 4 cm yr−1 during Meltwater Pulse 1A, which ... -
Transfer entropy computation using the Perron-Frobenius operator
Diego, David; Haaga, Kristian Agasøster; Hannisdal, Bjarte (Peer reviewed; Journal article, 2019)We propose a method for computing the transfer entropy between time series using Ulam's approximation of the Perron-Frobenius (transfer) operator associated with the map generating the dynamics. Our method differs from ... -
UncertainData.jl: a Julia package for working with measurements and datasets with uncertainties
Haaga, Kristian Agasøster (Journal article; Peer reviewed, 2019-11-01)UncertainData.jl provides an interface to represent data with associated uncertainties for the Julia programming language (Bezanson, Edelman, Karpinski, & Shah, 2017). Unlike Measurements.jl (Giordano, 2016), which deals ... -
Was common Era glacier expansion in the Arctic Atlantic region triggered by unforced atmospheric cooling?
Haaga, Kristian Agasøster; Bilt, Willem van der; Born, Andreas (Peer reviewed; Journal article, 2019-08-05)The timing and causes of Common Era (CE) glacier growth in the Arctic Atlantic region remain elusive. There is mounting evidence of advances that predate the Little Ice Age (1250–1850 CE); this challenges the view that ...
