Whale ecosystem services and co-production processes underpinning human wellbeing in the Arctic: case studies from Greenland, Iceland and Norway
(Springer Nature, 2020-10-31) Malinauskaite, Laura; Davíðsdóttir, Brynhildur; Cook, David; Ögmundardóttir, Helga; Hagfræðideild; Faculty of Economics; Félagsvísindasvið (HÍ); School of Social Sciences (UI)
The concept of ecosystem services (ES) has only just begun to be applied in the Arctic, and to an even lesser extent to marine mammals, such as whales. This chapter develops an ES cascade model and related ES co-production processes as they apply to whale resources in the Arctic. The result is a new conceptual model demonstrating the interconnectedness of social-ecological processes involving natural and human capital that enhance human wellbeing through the co-creation of whale ES. An ES cascade model is presented for whale ES, which connects the five linked stages of such ES production: the biophysical structure, functions, ecosystem services, the benefits to human wellbeing, and associated values. They are further expanded to include the co-production processes of whale ES as well as its main stages, inputs, and flows. These processes are illustrated using examples from ARCPATH case studies of coastal communities dependent on whale resources: Húsavík in Iceland, Andenes in Norway, and Ilulissat/Disko Bay in Greenland. The chapter aims to im-prove the understanding of the human dimensions of ES and the underlying processes that enable Arctic coastal communities to benefit from whales. It provides a starting point for further analysis of possible research and management approaches regarding whale resources in the Arctic.

The Icelandic Learned School as a secondary school in 19th-century Europe
(2025-12) Bjarnadóttir, Kristín; Menntavísindasvið
Iceland, inhabited by Norse people since the 9th c., had a population of fewer than 70,000 until the 1870s. Christianity, adopted in 1000 CE, brought literacy and cathedral schools, later reinforced by Lutheran Protestantism in 1550 and special privileges for Icelandic students at the University of Copenhagen. European secondary schools in the early 1800s placed increased emphasis on mathematics, sciences, and modern languages, modelled on the French lycée and Prussian gymnasium. In Iceland, the sole Icelandic secondary school could adapt to these changes due to the mathematician B. Gunnlaugsson, educated at the University of Copenhagen and trained in geodesy. By the 1870s, schools in the Danish school system were divided into a languages-and-history stream and a mathematics-and-science stream. However, the Iceland’s school was too small to split, there was no strong person to defend the study of mathematics, and a proposal to run a combined stream was rejected. A mathematics stream was only established in 1919.

ANALYSING AND MODELLING RECORDED EARTHQUAKE INDUCED STRUCTURAL RESPONSE
(2004-08-01) Snæbjornsson, Jonas Thor; Carr, Athol J.; Sigbjornsson, Ragnar; Department of Engineering
Earthquake induced acceleration data has been systematically collected in two reinforced cast-in-place concrete buildings over periods of 14 and 5 years respectively and the database from the two buildings presently contains 870 records from 107 events ranging from magnitude 2 to 6 with acceleration amplitudes of up to 34 % g. This data is used to examine structural behaviour and system parameters and their dependence on excitation conditions. The system identification based on the sampled data serves both as a baseline for damage identification as well as calibration for further structural modelling of the buildings. Visible damage is slight, but the system parameters reflect structural changes. There are clear indications that the system parameters are amplitude dependent, even for relatively small response amplitudes. Inelastic dynamic analyses were also carried out on one of the structures to investigate the reliability of the analytical models and to estimate the capacity of the building to sustain future earthquake events. The results show that the model does represent the structure and although it came through the recent earthquakes with no damage the structure has limited capacity to withstand any event that would be larger than those experienced to date.
