Accurate quantification of the millennial-scale mass balance Greenland ice sheet (GrIS) and its contribution to global sea-level rise remain challenging because sparse in situ observations key regions. Glacial isostatic adjustment (GIA) is ongoing response solid Earth ocean load changes occurring since Last Maximum (LGM; ~21 thousand years ago) may be used constrain GrIS deglaciation history. We use data from Global Positioning System network directly measure GIA estimate basin-wide LGM....
The effective management of the risks posed by natural and man-made hazards requires all relevant threats their interactions to be considered. This paper proposes a three-level framework for multi-risk assessment that accounts possible hazard risk interactions. first level is flow chart guides user in deciding whether multi-hazard approach required. second semi-quantitative explore if more detailed, quantitative needed. third detailed analysis based on Bayesian networks. Examples demonstrate...

In this study, was carefully synthesized to permit the collection its anodic and cathodic potentiodynamic polarization response. Difficulties producing bulk means that such data remains scarce date. is an important intermetallic forms Al Mg alloys containing silicon. work, response interpreted (and contrasted) context contain Mg2Si, revealing either local anode or cathode.
The Big Dry, a recent drought over southeast Australia, began around 1997 and continued until 2011. We show that between 2002–2010, instead of localized drought, there was continent‐wide reduction in water storage, vegetation rainfall, spanning the northwest to Australia. Trends storage were assessed using Gravity Recovery Climate Experiment (GRACE) Normalized Difference Vegetation Index (NDVI) data. Water NDVI are shown be significantly correlated across continent greatest losses occurred...
Natural hazards and climate-related disasters disregard political borders, where additional barriers can complicate mitigation, response recovery efforts within between the sectors of Climate Change Adaptation (CCA) Disaster Risk Reduction (DRR). The ESPREssO Project (Enhancing Synergies for Prevention in European Union) aims to improve management transboundary by encouraging closer synergies CCA DRR communities. Using targeted stakeholder interviews, questionnaires, Think Tank discussions...
The biological productivity of river-dominated estuaries is affected strongly by variation in freshwater inflow, which affects nursery habitat quality. Previous research has shown this generally true the upper San Francisco Estuary, California, USA; however, one endemic species high management importance, delta smelt (Hypomesus transpacificus), ambiguous population responses to river inflow variation. We hypothesized that population-level associations with abiotic metrics have not been...
This study analyzes the uncertainties in models of Greenland Ice Sheet (GIS) that arise from ill‐constrained geothermal heat flux (GHF) distribution. Within context dynamic GIS modeling, we consider following questions: (i) What is significance differences between existing GHF for modeling studies? (ii) How well does modeled controlled by agree with observational data? (iii) are relative contributions and climate forcing to misfit observed present‐day GIS? The results paleoclimatic...
[1] In this study, the memory of Greenland Ice Sheet (GIS) with respect to its past states is analyzed. According ice core reconstructions, present-day GIS reflects former climatic conditions dating back at least 250 thousand years before present (kyr BP). This fact must be considered when initializing an sheet model. The common initialization techniques are paleoclimatic simulations driven by atmospheric forcing inferred from records and steady state or conditions. When used, information...
Purpose Urban resilience is becoming increasingly important due to increasing degree of urbanization and a combination several factors affecting urban vulnerability. also understood as capacity system prepare, respond recover from multi-hazard threats. The purpose multi-risk approach (MRA) take into consideration interdependencies between multiple risks, which can trigger chain natural manmade events with different spatial temporal scales. this study understand correlation resilience....
We analyze 2006–2009 data from four continuous Global Positioning System (GPS) receivers located between 5 and 150 km the glacier Jakobshavn Isbræ, West Greenland. The GPS stations were established on bedrock to determine vertical crustal motion due unloading of ice Isbræ. All experienced uplift, but uplift rate at Kangia North, only front, was about 10 mm yr −1 larger than Ilulissat, ∼45 further away. This suggests that most is Earth's surface as thins loses mass. Our estimate Jakobshavn's...
We analyze the Venusian geoid and topography to determine relative importance of isostatic, elastic dynamic compensation mechanisms over different degree ranges. The power spectrum plotted on a log‐log scale shows significant change in its slope at about 40, suggesting transition from predominantly mechanism lower degrees an isostatic and/or higher degrees. focus lower‐degree interval. assume that (1) flow is whole mantle style, (2) long‐wavelength are purely origin, (3) density structure...
