Frozen in Time: Unveiling the Mysteries of Turner Glacier through Glaciological Research in Akshayuk Pass

Wai Yin Cheung

Glaciological research on Turner Glacier in Akshayuk Pass involves studying the physical properties and behavior of the glacier, as well as the surrounding environment, to better understand the dynamics of this glacial system. This includes measuring yearly snowfall, melt, and ice thinning to understand ice volume change and sea level contributions over the past 50+ years. By collecting and analyzing data over time, Queen's ICELab glaciologists can identify patterns and changes in glacial behavior, which can inform our understanding of climate change and its impact on northern environments. The research on Turner Glacier is part of a larger effort to study glacial systems around the world and develop strategies for mitigating the effects of climate change.

Inuit Nunangat: Where Two Worlds Collide (From the Art and Waste in Pannituuq [Pangnirtung] Project)

Inuit Nunangat is a site where differing epistemologies and cosmologies collide. The Arctic waste crisis stems from a culture of wasting that is capitalist and not Inuit. With the delicate Arctic ecosystem degrading due to climate change, escalating resource extraction, the opening of the Northwest Passage, and the expansion of NORAD, unprecedented volumes of waste and contaminants are causing unknowable changes in life, land, sea, and ice. At the intersection of art, politics and activism, the Art and Wastes in Pangnirtung Project challenges assumptions about Inuit and exposes the pervasive nature of settler colonization as the root cause of wastes.

Crystallization Pattern of a Common Salt Mixture

Lithium-ion batteries (LIBs) are rechargeable energy carriers that power electronic devices such as phones, cars, and hybrid/electric vehicles. The demand for lithium used to manufacture LIBs is expected to grow 30-fold by 2040. Industry primarily extracts lithium from rock ore and brine; however, the methods used are time-intensive and costly. Therefore, we are investigating alternative extraction methods that would reduce the energy consumption, waste production, and time intensity. The image, obtained by microscopy, is of salts that crystallized after evaporation of a lithium-containing brine.

Corneal Fingerprint

The cornea is one of the most densely innervated tissues in the human body. The high presence of sensory nerve endings makes the cornea extremely sensitive to pain and changes at the eye’s surface. This is particularly important in regulating tear production, a function which is impaired in dry eye disease. By analyzing changes in nerve patterns and ion channel expression, we aim to further clarify the role of corneal nerves in spontaneous pain and tear production in dry eye disease. This image shows the structural βIII-tubulin component of mouse corneal nerves at their unique convergence point.

Returning the Gaze

This was taken by Rubén Vargas at the wildlife sanctuary Proyecto Asis in Costa Rica, who captures the most beautiful images of the resident animals. I am standing in front of the capuchin enclosure observing the behaviours of Lulo, Lucy, Soplita, Pablita, and Cappuccino, while guided tours are taking place nearby. It is illegal to own wild animals in Costa Rica; these capuchins have been rescued from their past lives as companion animals or entertainers. While unable to be reintroduced to the wild, they receive life-long care and advocacy in the sanctuary community. My research looks at the intersections of animal welfare and conservation in Costa Rican sanctuaries, which are popular sites of sustainable, captive wildlife tourism. Here, the monkey returns my gaze in this photo, blurring the distinction between researcher and subject; I study him while he studies me.

Advancing Canada’s research infrastructure

kvd1 — Mon, 19 Dec 2022 16:37:36 +0000

On Friday, at SNOLAB, the Honourable François-Philippe Champagne, Minister of Innovation, Science and Industry, recognized the key role of research infrastructure by announcing more than $628 million to support 19 research infrastructure projects at institutions across the country, including two research facilities affiliated with Queen’s University.

Crystalline Acid

This photo taken with scanning electron microscopy depicts an extremely small yet precise volume (i.e., nanolitre-sized) of crystallized decanoic acid. We are using these spots of crystalline acid to extract and preconcentrate, or soak-up, chemicals of concern like opioids from wastewater samples. This preconcentration step improves our ability to monitor these chemicals. By doing so, we can improve how we detect these harmful compounds and protect local watersheds.

Polar Bear Denning

This photo demonstrates the collection of snow from inside a maternal polar bear den to collect environmental DNA. When the mother digs out the den, skin cells from its paws are abraded and stuck to the snow. Some preliminary research shows that we may be able to identify individual bears by analyzing these snow samples, information which can inform polar bear population management. My research is a pilot of ground-based non-invasive polar bear monitoring techniques, with a focus on Inuit inclusivity. Inuit Elders and polar bear hunters were key knowledge holders and collaborators throughout this research.

George Konana Collecting Ice

The Inuit practice an ongoing relationship with the land through camping, hunting, and fishing. As part of the BearWatch project, I explore how such knowledge, accumulated over many generations, and Inuit values can be ethically engaged in a community-based polar bear monitoring program. This picture is taken on one of our trips out on the land around Gjoa Haven during spring 2022. It captures George Konana collecting ice from the lake for tea. He traces ice with the right quality to give his tea a nice ‘reddish, brown’ color. At this exact moment, he cracks out a huge piece, enough for a month of tea.

Gastropod Mummy

This is a picture of a gastropod mummy laying down her egg cases. My research is to assess the stable isotope (C and O), clumped isotope (∆47), and trace element compositions of living and Quaternary shells from the Arabian/Persian Gulf. The aim is to link these analyses with modern oceanographic data to develop a robust proxy for understanding oceanographic change in the rock record. In simple terms, I am trying to link the shell chemistry with its surrounding environment and then use this link to assess oceanographic changes in the past 125K year. At the time of this picture, we were growing gastropods under laboratory conditions and performing in vitro fertilization of oysters.
