The Arctic continental shelves are important reservoirs of methane stored in gas hydrates and deeper geological formations. However, little is known about methane dynamics in deeper oceanic settings such as mid-ocean ridges, mainly due to operational challenges related to their remoteness. This study investigates a recently discovered methane seepage environment at Svyatogor Ridge, a sediment-covered transform fault on the western flank of the Arctic mid-ocean ridge west of Svalbard. Svyatogor Ridge was previously hypothesized to host deep gas hydrates and active fluid flow systems, which is a unique combination for this setting and requires geochemical evidence. Based on sediment and foraminiferal geochemistry, we demonstrate that Svyatogor Ridge hosts a shallow methane cycle with anaerobic oxidation of microbial methane, sustaining chemosynthetic communities at the seafloor. Our geochemical datasets also suggest that methane fluxes were higher in the past than today and long-lasting, with episodes of intense methane oxidation recorded in pre-Holocene sediments. Methane seepage is still ongoing at this location, although no evidence exists that methane is reaching the sea surface. The results provide the first evidence of a methane seepage environment ever reported from the ultra-slow spreading Arctic mid-ocean ridge, thus calling for a reevaluation of the role of this type of ridge in the ocean methane cycle.

Unconcerned with preparations for a wake or funeral, ‘The Emperor of Ice-Cream’ is a general statement about life and in particular pleasure, which the speaker enthusiastically endorses and celebrates in stanza one. A pervasive motif of contained pleasureables and the presence of a corpse in stanza two support the speaker’s implication that pleasure sometimes deviates from morality and sanity.

AbstractReverend Thomas Bridges’ Yagan-English dictionary (1879) has hitherto been little explored outside of linguistics but is highly valuable as a complementary source to archaeological, ethnohistorical, and ethnographic records in Tierra del Fuego (Argentina and Chile). The dictionary contains 22,800 entries and yields rich information concerning the marine lifeways of the Yagan and their and intimate knowledge about Fuegian seascapes. The idea behind this paper is that environments have strong bearings on linguistic vocabularies. Treating words as archaeological objects that map onto landscapes, we identify important landforms for Yagan marine foragers and Norwegian fisher-farmers in a comparative study of word frequencies in Bridges’ dictionary and Ivar Aasen’s Norwegian dictionary (1850). Moreover, we explore in detail how marine lifestyles and Fuegian seascapes emerge in Bridges’ dictionary and discuss the dictionary’s relevance for historical archaeology in Tierra del Fuego.

This thesis explores Indigenization in the context of archaeology and Western education at the Tundra Science and Culture Camp (TSCC), a government-run summer camp in the Northwest Territories, Canada. By collaborating with Indigenous knowledge holders, it begins the process of re-designing the Human History session—a program within the TSCC that focuses on archaeology and the cultural sites around the camp—to incorporate more Indigenous pedagogies and knowledge. Drawing on semi-structured interviews and participant observation, this thesis outlines an attempt to Indigenize the Human History session at the 2022 TSCC, its successes and challenges, and diverse conceptions of what it would mean to Indigenize the camp. This thesis concludes that the camp’s current Western structure and hidden curriculum greatly limit the extent to which programming within it can be effectively Indigenized. It recommends that camp organizers including the Indigenous instructors step back and articulate the aims of Indigenizing the camp in order to chart future directions for achieving those aims.
