Dynamic Response of Antarctic Ice Shelves to Bedrock Uncertainty

Abstract: Accurate and extensive bedrock geometry data is essential in ice sheet modelling. The shape of the bedrock on fine scales can influence ice sheet evolution, for example through the formation of pinning points that alter grounding line dynamics. Here we test the sensitivity of the BISICLES adaptive mesh ice sheet model to small-amplitude height fluctuations on different spatial scales in the bedrock topography provided by Bedmap2 in the catchments of Pine Island Glacier, the Amery Ice shelf and a region of East Antarctica including the Aurora Basin, Law Dome and Totten Glacier. We generate an ensemble of bedrock topographies by adding random noise to the Bedmap2 data with amplitude determined by the accompanying estimates of bedrock uncertainty. We find that the small-amplitude fluctuations result in only minor changes in the way these glaciers evolve. However, lower-frequency noise, with a broad spatial scale (over tens of kilometres) is more important than higher-frequency noise even when the features have the same height amplitudes and the total noise power is maintained. This is cause for optimism regarding credible sea level rise estimates with presently achievable density of thickness measurements. Pine Island Glacier and the region around Totten Glacier and Law Dome undergo substantial retreat and appear to be more sensitive to errors in bed topography than the Amery Ice shelf region which remains stable under the present-day observational data uncertainty.

Stopping the flood: could we use targeted geoengineering to mitigate sea level rise?

Abstract: . The Marine Ice Sheet Instability (MISI) is a dynamic feedback that can cause an ice sheet to enter a runaway collapse. Thwaites Glacier, West Antarctica, is projected to be the largest individual source of future sea level rise and may have already entered MISI. Here, we use a suite of coupled quasi-2-D ice–ocean simulations to explore whether targeted geoengineering using either a continuous artificial sill or isolated artificial pinning points could counter a collapse. Successful interventions occur when the floating ice shelf regrounds on the structure, increasing buttressing and reducing ice flux across the grounding line. Regrounding is more likely with a continuous sill that is able to block warm water transport to the grounding line. The smallest design we consider is comparable in scale to existing civil engineering projects but only has a 30 % success rate, while larger designs are more effective. There are multiple possible routes forward to improve upon the designs that we considered, and with decades or more to research designs it is plausible that the scientific community could come up with a plan that is both effective and achievable. While reducing emissions remains the short-term priority for minimizing the effects of climate change, in the long run humanity may need to develop contingency plans to deal with an ice sheet collapse.

Coordinating co-production in complex network settings

Abstract: This article draws together the concepts of network management and co-production with complexity sciences. So far, these approaches have rarely been connected in research literature. We suggest that this conceptual framework offers new insights for analyzing the challenges of co-production in complex network settings in the local public services. The aim of the article is to find out how complex network structures meet the co-production process in the context of social and health care services. The empirical part of the article presents a Finnish case study of a multiprofessional service network producing social and health care services for youth. Here, the clients, in this case children and young people with a need for social services, often need multiple services from different service providers simultaneously. Our research findings suggest that the outcomes of the service process are not only dependent on the client's needs, but rather on organizational and professional interests. Our research gives ne...

Loving and Conquering Nature: Shifting Perceptions of the Environment in the Industrialised Russian North

Abstract: This article examines complex patterns of interaction between human settlement and the environment in the industrialised Russian north. I analyse how new mining towns, built during the Soviet period, were located and integrated into the environment. Residents have participated in the industrial processing of natural resources in the work domain, also developing a strong emotional attachment to the natural environments while spending leisure time around the cities. In both perception of physical space and ideas about place, the main dividing principle is between the spheres of work and leisure.

Motivational Factors for User Engagement with mHealth Apps.

Abstract: The widespread adoption of smartphones creates an enormous potential to improve healthcare services. Numerous apps, sensors, and devices are developed for health self-management purposes. However, adoption rates remain low and long-term user engagement is a major issue. The goal of this study is to identify major motivational factors that can facilitate prolonged use of mobile health systems. To this end, we conducted 16 interviews with representatives of various cultural backgrounds, disease history, age, and gender. Participants' experiences indicated that existing systems were unable to answer their self-management needs properly. People with a disease history favored learning from data, as well as from others via social media integration. People without chronic disease felt more reserved about social media integration. In conclusion, systems that collect and share personal data should have a clear opt-in or opt-out option to motivate usage. Additionally, researchers and mobile health system developers could achieve long-term adoption by giving clear answers to privacy and trust issues, while offering people strong added value according to their individual needs.
