They were cheerfully assisted in this technically challenging task by UDel undergraduate Lauren Brown and the Coast Guard contracted networking specialist, Joe DiGiovanni. Our talented Canadian photojournalist, Lee Narraway, was seen behind the lens throughout much of the cruise. We very much look forward to the articles she is producing. Given all of the digital cameras on board, the number of pictures produced and shared by us is enormous. Among them are many stunning shots of the seascape, landscape, the ship and people. To me, this seems befi tting of our endeavor to better understand a stunning piece of our planet. 5 Research Cruise Report: Mission HLY 031 Science Program Summary The Arctic Ocean plays a pivotal role in the global • Εxplore bivalve shell records as a proxy of hydrologic cycle by returning freshwater, in the form of historical throughfl ow variability and retrieve sediment freshened seawater and ice, to the North Atlantic at Fram cores that can used to address longer time-scale Strait and through passages of the Canadian Archipelago. variability in future studies Available estimates suggest that freshwater fl uxes of • Εxploit the fi ndings of this study to improve comparable magnitude pass through Fram Strait and the parameterization of Archipelago throughfl ow in Arctic combined three main passages of the Archipelago.

CATs is the outgrowth of a pilot effort, the Arctic Canada Watch, established in 1997. Moorings enabling year-round measurements were first placed in western Lancaster Sound and Cardigan Strait in 1998. These carried instruments to measure current, temperature and salinity and utilized innovations to address the unique challenges of observing: 1) current direction near the geomagnetic pole; 2) salinity within the hazardous 30-m zone beneath drifting ice pack. These early installations have been maintained and augmented since 1998. In 2003, a large array of instruments was installed across the third principal path for Canadian Arctic through-flow, Nares Strait.

  • Paleocene Alkaline Volcanism in the Nares Strait Region Related to Strike-Slip Tectonics
    Paleocene Alkaline Volcanism in the Nares Strait Region Related to Strike-slip Tectonics Solveig Estrada & Detlef Damaske Federal Institute for Geosciences and Natural Resources (BGR), Hannover, Germany ([email protected]) The tectonic development of the North Atlantic, the Labrador Sea/Baffin Bay and the Eurasian Basin of Arctic Ocean led to relative movements between the Greenland Plate and the North American Plate. There has been a debate for many years, whether the Nares Strait between northwest Greenland and Ellesmere Island marks an ancient plate boundary in terms of a left-lateral transform fault (Wegener Fault) or whether there was no movement between Greenland and Ellesmere Island at all. New data were acquired during joint German-Canadian geological field work on northeast Ellesmere Island 1998-2000 (Mayr 2008), followed in 2001 by a geoscience cruise in Nares Strait (Tessensohn et al. 2006). Indications for sinistral strike-slip movements followed by compressive tectonics were found at the western margin of northern Nares Strait (Saalmann et al. 2005). Paleogene basins on Judge Daly Promontory, northeast Ellesmere Island, are bounded by a complex pattern of strike-slip and thrust faults. The clastic sediments in the basins are rich in volcanogenic material. Volcanic pebbles within the Cape Back basin near Nares Strait are derived from lava flows and ignimbrites of a continental rift-related, strongly differentiated, highly incompatible element enriched, alkaline volcanic suite (Estrada et al. 2009). 40Ar/39Ar amphibole and alkali feldspar ages indicate that volcanism was active around 61–58 Ma and was probably contemporaneous with sedimentation within the Paleogene pull-apart basins on Judge Daly Promontory formed by sinistral strike-slip tectonics parallel to the present-day Nares Strait.

  • Examining Precontact Inuit Gender Complexity and Its
    EXAMINING PRECONTACT INUIT GENDER COMPLEXITY AND ITS DISCURSIVE POTENTIAL FOR LGBTQ2S+ AND DECOLONIZATION MOVEMENTS by Meghan Walley B.A. McGill University, 2014 A thesis submitted to the School of Graduate Studies In partial fulfillment of the requirements for the degree of Master of Arts Department of Archaeology Memorial University of Newfoundland May 2018 St. John’s, Newfoundland and Labrador 0 ABSTRACT Anthropological literature and oral testimony assert that Inuit gender did not traditionally fit within a binary framework. Men’s and women’s social roles were not wholly determined by their bodies, there were mediatory roles between masculine and feminine identities, and role-swapping was—and continues to be—widespread. However, archaeologists have largely neglected Inuit gender diversity as an area of research. This thesis has two primary objectives: 1) to explore the potential impacts of presenting queer narratives of the Inuit past through a series of interviews that were conducted with Lesbian Gay Bisexual Transgender Queer/Questioning and Two-Spirit (LGBTQ2S+) Inuit and 2) to consider ways in which archaeological materials articulate with and convey a multiplicity of gender expressions specific to pre-contact Inuit identity. This work encourages archaeologists to look beyond categories that have been constructed and naturalized within white settler spheres, and to replace them with ontologically appropriate histories that incorporate a range of Inuit voices. I ACKNOWLEDGEMENTS First and foremost, qujannamiik/nakummek to all of the Inuit who participated in interviews, spoke to me about my work, and provided me with vital feedback. My research would be nothing without your input. I also wish to thank Safe Alliance for helping me identify interview participants, particularly Denise Cole, one of its founding members, who has provided me with invaluable insights, and who does remarkable work that will continue to motivate and inform my own.

HANS OFF!: THE STRUGGLE FOR HANS ISLAND AND THE POTENTIAL RAMIFICATIONS FOR INTERNATIONAL BORDER DISPUTE RESOLUTION Christopher Stevenson* Abstract: As global warming continues to warm the Arctic seas, more of the Arctic is free of ice for longer periods. The possibilities for exploita- tion of natural resources and for control over Northern shipping lanes have prompted countries’ renewed interest in their competing claims to the region. Recently, Denmark and Canada have clashed over their com- peting claims to a small, uninhabitable rock known as Hans Island. While this island may not seem signiªcant, the eventual resolution of this border dispute may have widespread ramiªcations for the resolution of interna- tional conºicts in other remote, uninhabited areas.

    ARCTIC VOL. 71, NO. 3 (SEPTEMBER 2018) P. 334 – 348 https://doi.org/10.14430/arctic4735 Seal Occurrence and Habitat Use during Summer in Petermann Fjord, Northwestern Greenland Kate Lomac-MacNair,1,2 Martin Jakobsson,3 Alan Mix,4 Francis Freire,3 Kelly Hogan,5 Larry Mayer6 and Mari A. Smultea2 (Received 29 June 2017; accepted in revised form 30 May 2018) ABSTRACT. Ice-associated seals are considered especially susceptible and are potentially the first to modify distribution and habitat use in response to physical changes associated with the changing climate. Petermann Glacier, part of a unique ice-tongue fjord environment in a rarely studied region of northwestern Greenland, lost substantial sections of its ice tongue during major 2010 and 2012 calving events. As a result, changes in seal habitat may have occurred. Seal occurrence and distribution data were collected in Petermann Fjord and adjacent Nares Strait region over 27 days (2 to 28 August) during the multidisciplinary scientific Petermann 2015 Expedition on the icebreaker Oden. During 239.4 hours of dedicated observation effort, a total of 312 individuals were recorded, representing four species: bearded seal (Erignathus barbatus), hooded seal (Crystophora cristata), harp seal (Pagophilus groenlandicus), and ringed seal (Pusa hispida). Ringed seals were recorded significantly more than the other species (χ2 = 347.4, df = 3, p < 0.001, n = 307). We found significant differences between species in haul-out (resting on ice) behavior (χ2 = 133.1, df = 3, p < 0.001, n = 307). Bearded seals were more frequently hauled out (73.1% n = 49), whereas ringed seals were almost exclusively in water (93.9%, n = 200).
