The hydrothermal vent field Loki’s Castle is located in the Mohns-Knipovich bend (73°N) of the ultraslow spreading Arctic Mid-Ocean Ridge (AMOR) close to the Bear Island sediment fan. The ...hydrothermal field is venting up to 320° C hot black smoker fluids near the summit of an axial volcanic ridge. Even though the active chimneys have grown on a basaltic ridge, geochemical fluid data show a strong sedimentary influence into the hydrothermal circulation at Loki’s Castle. Compelling evidence for a sediment input is given by high alkalinity, high concentrations of NH4+, H2, CH4, C2+ hydrocarbons as well as low Mn and Fe contents. The low δ13C values of CO2 and CH4 and the thermogenic isotopic pattern of the C2+ hydrocarbons in the high-temperature vent fluids clearly point to thermal degradation of sedimentary organic matter and illustrate diminution of the natural carbon sequestration in sediments by hydrothermal circulation. Thus, carbon-release to the hydrosphere in Arctic regions is especially relevant in areas where the active Arctic Mid-Ocean Ridge system is in contact with the organic matter rich detrital sediment fans.
The article is the first presentation of detailed research of bird bones from six Teutonic Order castles built in the 13th century in the historical territory of Prussia, mainly in Terra Culmensis – ...the Kulmerland. The aim was to assess diachronic trends in bird exploitation at these sites. 28 different species were identified within the three historical periods represented in the occupation phases of these castles – the Pre-Teutonic Order or early medieval period, the Teutonic Order's period of rule and that of the Kingdom of Poland. The most numerous were domestic fowl (chicken) and geese, and their anatomical composition, age, sex and biometrics are described. A small percentage consists of wild species. The significance of birds for the castle elites in all periods was assessed through a comparison of archaeo-ornithological and historical data. The bird remains (and eggshells) from these castles largely represent the waste from food preparation, but some can be connected with hawking, the use of feathers and down, as well as for particular species kept for ornamental purposes. All of these are defining characteristics of high-status sites in the medieval and early modern periods.

This paper reconsiders Stephen Castle's classic paper Why Migration Policies Fail. Beginning with the so-called migration crisis of 2015 it considers the role of numbers is assessing success or ...failure. It argues that in the UK public debates about immigration changed with European Union (EU) Enlargement in 2004, when the emphasis shifted from concerns about asylum to concerns about EU mobility. Concerns were exacerbated by the government's failure to meet its promise to reduce net migration. This policy is hampered by the general problem of definition of "migrant" and the gap between statistical measures and popular usage in which "migration" signifies problematic mobility. In fact, concern about migration has become a placeholder for concerns about globalization and democratic accountability. A new politics of migration must make connections between migrants and citizens, but also between migration and other global processes, particularly outsourcing and the exploitation of labour and resources in the global south.

Dublin Castle stands as a signifier of both conflict and conciliation between Ireland and Britain over recent centuries. On 16 January 2022, all of Ireland’s mainstream political parties gathered ...there on the centenary of the castle’s handover by the last lord lieutenant of Ireland, Viscount FitzAlan of Derwent, to the provisional government of Ireland led by Michael Collins, which took place after the Dáil endorsed the 1921 Treaty. Jarlath Kearney, Peter Shirlow and Etain Tannam show that a century after that treaty and the partition of the island, the facts and themes flowing from that period – particularly ongoing identity and culture contests over Northern Ireland’s constitutional status – remain live. It is essential in managing future challenges that British-Irish intergovernmental cooperation thrives and that the Belfast/Good Friday Agreement is implemented robustly. This is not simply because of Northern Ireland, but because of the host of geopolitical and international security challenges ahead.◼
Within the Spessart low mountain range in central Germany, numerous castle ruins of the 13th century ce exist. Their construction and destruction were often determined by the struggle for political ...and economic supremacy in the region and for control over the Spessart's natural resources. Wahlmich Castle is located in a relatively uncommon strategic and geomorphological position, characterized by a fairly remote position and atypical rough relief. In order to reconstruct the local relief development and possible human impact, a multi‐method approach was applied combining two‐dimensional geoelectrical measurements, geomorphological mapping and stratigraphic‐sedimentological investigations. This provides new insights into the influence of landscape characteristics on choices of castle locations.
The combined geoelectrical, geomorphological and stratigraphic‐sedimentological data show that the rough relief is of natural origin and influenced by regional faulting, which triggered sliding and slumping as well as weathering and dissection of the surface deposits. The rough relief and the lithology permitted intensive land use and building activities. However, the location of the castle offered access to and possibly control over important medieval traffic routes and also represented certain ownership claims in the Aschaff River valley.
The economic situation combined with rivalry between different elites led to the castle being built in a geomorphological challenging and strategically less valuable location. Focusing on castles located in rare and challenging geomorphological positions may therefore lead to a better understanding of castle siting in the future.
In this multi‐method study, geophysical measurements, geographic information system‐based terrain analysis and stratigraphic‐sedimentological investigations were used to reconstruct the local relief development of a medieval castle site in central Germany. In contrast to assumptions about an anthropogenically influenced development of the relief, it could be proven that natural processes caused sliding and subsidence processes, which created a rough and atypical landscape. Overall, this study provides new insights into the influence of landscape characteristics on choices of castle locations.
