Eurasian Ice Sheet collapse was a major source of Meltwater Pulse 1A 14,600 years ago

…, H Haflidason, Y Yokoyama, KA Haaga… - Nature …, 2020 - nature.com
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 …

Common species link global ecosystems to climate change: dynamical evidence in the planktonic fossil record

B Hannisdal, KA Haaga, T Reitan… - Proceedings of the …, 2017 - royalsocietypublishing.org
Common species shape the world around us, and changes in their commonness signify
large-scale shifts in ecosystem structure and function. However, our understanding of long-term …

Evidence of early deglaciation (18 000 cal a bp) and a postglacial relative sea‐level curve from southern Karmøy, south‐west Norway

…, J Mangerud, K Agasøster Haaga… - Journal of …, 2019 - Wiley Online Library
Based on six consistent radiocarbon dates from the isolation basins Grødheimsvatnet and
Kringlemyr, we estimate a minimum deglaciation age for southern Karmøy, an island in outer …

Transfer entropy computation using the Perron-Frobenius operator

D Diego, KA Haaga, B Hannisdal - Physical Review E, 2019 - APS
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 …

A simple test for causality in complex systems

KA Haaga, D Diego, J Brendryen… - arXiv preprint arXiv …, 2020 - arxiv.org
We provide a new solution to the long-standing problem of inferring causality from
observations without modeling the unknown mechanisms. We show that the evolution of any …

[PDF][PDF] TimeseriesSurrogates. jl: a Julia package for generating surrogate data

KA Haaga, G Datseris - Journal of Open Source Software, 2022 - joss.theoj.org
The method of surrogate data is a way to generate data that preserve one or more statistical
or dynamical properties of a given timeseries, but are otherwise randomized. Surrogate time …

Common species link global ecosystems to climate change

B Hannisdal, KA Haaga, T Reitan, D Diego, LH Liow - bioRxiv, 2016 - biorxiv.org
Common species shape the world around us, and changes in their commonness signify
large-scale shifts in ecosystem structure and function 1 - 4 . Dominant taxa drive productivity and …

[HTML][HTML] Forcing of late Pleistocene ice volume by spatially variable summer energy

KA Haaga, J Brendryen, D Diego, B Hannisdal - Scientific Reports, 2018 - nature.com
Abstract Changes in Earth’s orbit set the pace of glacial cycles, but the role of spatial variability
in the insolation forcing of global ice volume remains unknown. Here, we leverage the …

[PDF][PDF] UncertainData. jl: a Julia package for working with measurements and datasets with uncertainties

KA Haaga - 2019 - bora.uib.no
UncertainData.jl provides an interface to represent data with associated uncertainties for the
Julia programming language (Bezanson, Edelman, Karpinski, & Shah, 2017). Unlike …
