  • Brock researcher awarded Fulbright Canada Research Chair

    Kevin Turner, Associate Professor in the Department of Geography and Tourism Studies, has been awarded a Fulbright Canada Research Chair in Arctic Studies at the University of Washington.

    Next winter, Turner — who is also cross-appointed to the Department of Earth Sciences, an Associate Member of the Department of Biology and a Co-Founder of the Water and Environment Lab at Brock — is set to spend six months teaching and researching the impacts of climate change on northern landscapes, lakes, rivers and wetlands.

    “As land and water adjust to changes in climate, we are presented with many questions of urgent global concern, particularly to northern stakeholders,” says Turner. “Changing landscape components, such as permafrost thaw, will influence global carbon cycles and climate-warming greenhouse gases. This is a far-reaching concern.”

    The Fulbright Canada Research Chair in Arctic Studies recognizes Associate Professor Kevin Turner’s ongoing work in mapping Arctic lake and river responses to landscape disturbances caused by the changing climate, as shown in this photo he captured of a landslide due to thawing permafrost.

    Turner notes that there are also local concerns, including how landscape disturbance such as fire, landslides and lake drainage can affect water quality, ecology, infrastructure and travel. To address some of these issues, he will use the research component of the Chair position to “take inventory of the landscape changes and identify how they influence the hydrology and chemistry of lakes, rivers and wetlands.”

    “The research aims to enhance our knowledge of climate change impacts and feedbacks,” says Turner, who has been conducting fieldwork in northern Yukon for 14 years. “We do this by identifying linkages among landscape changes and lake and river biogeochemistry across the ecologically and culturally important landscapes of the Yukon River Basin.”

    The Fulbright Canada Research Chair also involves teaching for the University of Washington’s minor in Arctic Studies. Turner plans to share with students both remote sensing and field-based techniques for collecting landscape data, as well as teaching students how to analyze, synthesize and share their findings with broad audiences.

    Turner says he was honoured to be selected for the Fulbright Canada Research Chair.

    “There are several colleagues I look up to who have received it in the past,” he says. “I am grateful that I have this opportunity to extend my research program and collaborations across borders.”

    Turner is attracted to the University of Washington for several reasons, not the least of which is the chance to work more closely with colleagues whom he has met during his affiliation with the National Aeronautics and Space Administration’s (NASA) Arctic-Boreal Monitoring Experiment.

    He also notes that the Henry M. Jackson School of International Studies, where the position will be homed, is a “leader in advancing the understanding of and engagement in world issues.”

    “Several researchers and dignitaries from Yukon participate at their various forums, including Dana Tizya-Tramm, Chief of the Vuntut Gwitchin First Nation (VGFN; Old Crow, Yukon), who discussed impacts of climate change on Indigenous communities and their resilience during a meeting of the World Affairs Council,” says Turner. “The priorities of my research program have been guided by the vast knowledge that the VGFN have of their traditional territory and the observations they have made over generations.”

    Turner also has personal reasons to be excited about relocating to Seattle for the duration of the position.

    “As a past varsity rower, I’m interested in seeing where that 1936 crew came from on their way to gold in Germany,” Turner admits. “I should also mention that I’m a big fan of several musical artists who came from Seattle — top of the list would be Jimi Hendrix.”

    However, the ongoing COVID-19 pandemic may interfere with Turner’s plans. The position is set to begin in January 2021, but a few pieces need to fall into place before then.

    “We are currently living in a world of virtual-communications and we are unsure of how this will change by the end of the year,” says Turner, adding that international visas were suspended by the U.S. Department of State until the end of 2020. “Fulbright is currently looking into these issues and will provide updates as they learn more. I have hope that things will change for the better as the new year approaches.”

    Turner also points out that “climate change will not pause for us, and there is a lot within that realm that we need to learn.”

    “Arctic and subarctic regions are undergoing climate warming at a rate twice above the global average, and changes in precipitation patterns occurring — less snow and more rain, for example — are having major impacts on these landscapes,” says Turner. “The processes that cause permafrost degradation are often triggered by warm and wet conditions, and since about a third of the world’s carbon is locked in permafrost, this has complex ramifications for the rest of the world.”

  • New research by geography alumnus looks at fire history in southwest Yukon Territory

    New research by Tyler Prince (Brock Geography and Master of Sustainability alumnus), Michael Pisaric, and Kevin Turner was published this week in Frontiers in Ecology and Evolution. Read more below.

    Abstract:

    Previous research suggests climate warming during the current century is likely to lead to an increase in the frequency and severity of wildfire. Recent wildfire seasons in northern Canada generally support these studies, with some of the worst fire seasons on record occurring during the past decade. While we can readily track the spatial and temporal distribution of these events during recent decades using satellite-derived data, historical records of past fire activity are relatively short. Proxy records of past fire activity are needed to fully understand how fire regimes may be shifting in response to changing climatic conditions. A high-resolution fire record, dating back to the early-Holocene, has been reconstructed using a 512-cm sediment core collected from a small lake in southwest Yukon Territory, Canada. Macroscopic charcoal was counted throughout the core at contiguous 0.5-cm intervals. The core was also analyzed for loss-on-ignition and magnetic susceptibility. Fossil pollen preserved in the lake sediment was analyzed to determine vegetation change throughout the Holocene. Macroscopic charcoal analysis indicates an active fire history throughout the record, with 90 fires occurring throughout the Holocene. CharAnalysis indicates an average signal to noise index of 6.2, suggesting the peaks are significant and detectable from the slowly varying background level. Results suggest the fire regime in this region responds to both top-down (climate) and bottom-up (vegetation) factors. Fire return intervals changed in response to shifts in precipitation and temperature as well as the expansion of lodgepole pine into the region. The shifts in precipitation and temperature were attributed to the oscillation of the Aleutian Low pressure system and fluctuations in climate associated with the Medieval Climate Anomaly and the Little Ice Age.

  • GoGeomatics interview: Associate Professor Kevin Turner

    STORY REPOSTED FROM GOGEOMATICS | NOVEMBER 22, 2018

    This installment of our ongoing series on GIS and education in Canada features Associate Professor Kevin Turner from Brock University’s Department of Geography and Tourism Studies.

    Jonathan Murphy: Hi Kevin, and thank you for taking the time to chat with us about your career and your program at Brock. How did your passion for geography start?

    Kevin Turner: I was drawn to nature at an early age. I can trace my interests in geography and the natural sciences to various times starting in Grade 6 when Mr. Wayne Graham (Hamlet Public School, Stratford) put the class in contact with Daphne Sheldrick, the operator of an elephant orphanage in Kenya. While it may not have been geography-focused at the time, I became quite aware of the negative influence people can have on the world and the animals within it. My interest in Geography grew during my grade 11 geography class with Mr. Al Vredeveld at Stratford Central Secondary School. I also had the interests of a couple family members rub off on me. Add in a number of nature documentaries, family camping, a couple David Suzuki books, and some great advice from my high school academic advisor (Mrs. Heather Jesson), and soon I was off to Trent for my undergraduate joint major in physical geography and biology. I had some fantastic profs at Trent who continued to lure me into the natural sciences.

    I was a tree planter during summers in northern Ontario, Alberta, and BC, which continued to build my appreciation for the outdoors. I knew that I wanted to study nature in some way and somehow set myself up to have a career that included working outside in a remote landscape. The motivation for this continued after graduation while hiking and mountaineering in Ecuador and Peru.

    I decided that I wanted to learn more about landscape-scale systems and that building skills in digital mapping and spatial analysis was needed. I received a post-grad certificate in the GIS Applications Specialist program at Sir Sandford Fleming College and got my first ‘career’ job at a geophysical exploration firm out of Guelph, Ontario. I found myself designing projects and surveying in nice places around eastern Canada and the US. In addition to coordinating and conducting the field surveys, I wrote scripts in VBA to design the projects and quality check the data coming in, which I reported to clients.

    I wanted more involvement on the research side of things, especially with water resources, and decided to begin graduate studies in 2007 at Wilfrid Laurier University. The timing was right considering that my new supervisor at the time (Dr. Brent Wolfe) and many other colleagues were beginning a multidisciplinary research program in Old Crow Flats, Yukon, supported by the Government of Canada International Polar Year. It was an incredible experience that presented many opportunities to travel to the north for fieldwork and interact with people of the Vuntut Gwitchin First Nation, who were the driving force of the program. Fast-forward 6.5 years and I’m beginning a position at Brock University where I secured external funding to build on my research in northern Yukon and also Northwest Territories.

    Jonathan Murphy: You were recently promoted to associate professor at Brock–congratulations! What do you teach there and what is your research focus?

    Graduate Research Assistant Brent Thorne, Image by Kevin Turner

    Kevin Turner: My teaching focus in the Department of Geography and Tourism Studies at Brock is mostly geomatics. We offer a suite of geomatics courses spanning introduction and advanced remote sensing, GIS, cartography, and quantitative research design and methodology. Once students learn to grasp the various concepts, I encourage them to implement creative and critical analysis with datasets and topics that interest them most. I also strive to make them comfortable with using computer programming for automating tasks so they can accomplish more by generating useful customized tools of their interest. We’ve been lucky to have some very strong students come through our programs and it has been rewarding to see them enjoy and take a lot away from our programs.

    Jonathan Murphy:  What is the geography and tourism program like at Brock?  What makes the program unique?

    Kevin Turner: Within the Department of Geography and Tourism Studies, we have a diverse set of streams that students can pursue, which include the following:

    • BA Geography (focus on human geography)
    • BSc Geography (focus on physical geography)
    • Concurrent BA or BSc (Honours) – Geography/ Education
    • Combined Geography majors (e.g., Geography + Biology, Child and Youth Studies, Computer Science, Earth Sciences, Economics, History Labour Studies, and more)

    We offer seven geomatics-focused courses as well as a fourth-year co-op course where students can gain additional hands-on experience in a position of their choosing. The wide-ranging options available provide students with the ability to shape their studies according to their interests. I take this approach with the four geomatics (i.e., mostly GIS and spatial analysis and statistics) courses that I teach. Students learn essential GIS/RS skills for evaluating spatial patterns throughout my courses and have opportunities to implement them within the context of their choice. The aim is to build their knowledge of geography and related fields through enhancing their analytical capabilities. We are lucky to work with the Brock University Map, GIS, and Data Library, which is conveniently located beside our department where students can have access to necessary resources for building their skills in geomatics. I pull a lot from my private sector and ongoing academic research experiences when updating and implementing my courses. I’m happy to report that following graduation, many students who have taken our courses have been quite successful at finding employment and/or additional research programs in their fields of interest.

    Jonathan Murphy:  What geomatics classes or skills are students acquiring by the time they graduate from Brock?

    Kevin Turner. Image by Brent Thorne

    Kevin Turner: Students learn to use many GIS/RS software for their analytical needs and interests. We have many computer labs throughout Brock University with site licenses for ESRI products including ArcMap and ArcGIS Pro as well as ENVI for remote sensing analyses. My courses also include a lot of content focused on open source solutions including R, QGIS, and various integrated development environments. In addition to utilizing databases for spatial analyses (3D, network, spatial statistical, etc.) and geoprocessing, my courses bring in application development so that they can learn to automate or customize their workflow in an effort to eliminate redundancies. This comes from using Python and R programming languages.

    Jonathan Murphy: The program has some interesting aspects to it.  Can you tell us a bit about the weeklong experiential learning exercise in central Ontario for the fourth year students?

    Kevin Turner: We have several ‘experiential learning’ opportunities within our programs. It is geography after all and it is important to get students into the field to get hands-on experience. The Peterborough field course is the longest running one in the department where physical and human geography students get a chance to conduct their research of interest. We offer additional field courses for geography and tourism students to other national and international destinations that have included Croatia, Vancouver, and Chicago. London, England is on the list for next year. I take graduate and undergraduate students who are working on their theses for Geography and Tourism Studies or Earth Science with me to my northern study sites including Old Crow, Yukon, and Yellowknife, Northwest Territories.

    Jonathan Murphy: I understand that 40% of your job is focused on research. Can you describe your research program and how you and the students working with you accomplish it?

    Research Assistant Brent Thorne. Image by Kevin Turner

    Kevin Turner: My research program focuses on tracking climate-induced landscape changes and the associated responses of lakes and rivers in northern Canada. For example, the changes that myself and the people of Old Crow, Yukon have observed include an increased frequency of lake drainage, shoreline permafrost thaw slumping (i.e., landslides), shrub vegetation proliferation, and fire. Taking inventory of these phenomena requires the use of available remotely sensed data products and multispectral imagery we collect using unmanned aerial vehicles. Other datasets are coming from airborne campaigns of the NASA Arctic Boreal Vulnerability Experiment, which I am affiliated with. We also sample water and sediment from lakes and rivers, which undergoes a suite of water chemistry and isotope analysis. This information provides an indication of how the landscape changes have impacted water quality, hydrology and carbon export over multiple temporal scales.

    Geomatics tools are essential at all stages of the research process including data acquisition, processing, analysis and integration of final catchment map layers (e.g., ground conditions, land cover type, ground temperatures, etc.). We also identify where lakes and rivers across the study sites are more vulnerable to being impacted by changing climate and landscape features. The overall aim is to provide key insight required for predicting how these places will respond to future change and how that will impact downstream environments.

    Managing a northern research program in a southern Canada university can be a challenge. However, it is a chance of a lifetime for the students to venture out to important remote Canadian landscapes and work with stakeholders, including those who want to learn about the spatial patterns we see in their traditional territories.

    Jonathan Murphy: Thanks for taking the time to talk to the GoGeomatics community.  We hope to see you and your students at our monthly GoGeomatics socials in Niagara!

  • Brock student wins two awards in national science photo competition

    Dana Harris calls Nov. 9 her “special day.”

    It was on that day last week that the Master of Sustainability student became a first time aunt, and also the day she was told, in the strictest of confidence, that she had captured two top prizes in a national science research photo competition.

    Harris had to keep the secret of her achievement under wraps until Nov. 14, when the Natural Sciences and Engineering Research Council of Canada (NSERC) announced the winners of its Canada-wide Science Exposed competition.

    The competition showcases images taken during scientific research being conducted in all fields by faculty and student researchers in post-secondary institutions and researchers in public and private research centres.

    Dana Harris photo submission

    Dana Harris’ submission to the NSERC Science Exposed competition
    featuring cells of the jack pine tree.

    Harris received the People’s Choice Award and a Jury Prize for her photo, “Exploring the Jack Pine Tight Knit Family Tree.”

    “It’s a super huge honour to have people sharing my photo, voting on it and just enjoying it,” says Harris. “And, to get that mention from the NSERC jury members was really gratifying.”

    Diane Dupont, Dean of Graduate Studies, said the Faculty is “so proud of Dana and her success in the NSERC Science Exposed photography contest.”

    “To win the People’s Choice Award is an outstanding achievement,” Dupont said. “This award is a testament to the cutting-edge research she is pursuing involving the globally-relevant topic of climate change.”

    Harris’ photo shows phases of developing xylem cells, stained in different colours, that are found in a wood sample cored from the outermost part of a jack pine tree in the Northwest Territories, where she is from.

    The image, shot from a microscope, shows the jack pine tree’s phloem, cambial and xylem cells (blue dye) and mature xylem cells (red dye) in a thin slice of the wood. It is one of a series of images taken weekly over the past year to track the growth of the jack pine tree’s various cells.

    “This type of information is useful for researchers who create climate reconstructions using tree rings as a source of historical climate data,” explains Harris.

    She thanked her supervisor, Professor of Geography and Tourism Studies Michael Pisaric, and her fellow student researchers in Brock’s Water and Environment Laboratory (WEL) for their support.

    “Dana’s research is helping to understand how important tree species in the boreal forest are affected by climate change,” says Pisaric. “Her research also helps to inform larger questions concerning carbon uptake by the boreal forest.

    “Northern regions of Canada are being impacted by changing climatic conditions, including warmer temperatures, changing precipitation regimes and altered frequency and intensity of forest fires and other disturbance agents.”

    The WEL lab is co-directed by Pisaric and Associate Professor of Geography and Tourism Studies Kevin Turner, with the aim to explore how terrestrial and aquatic ecosystems in Canada’s North are changing in response to climatic and environmental change.

    Harris says she is happy that research on climate change and environmental conditions in the North were acknowledged with awards in the competition.

    Earlier this year, the photos of 20 researchers from across Canada, including Harris’s entry, were shortlisted and posted on NSERC’s website. People viewing the 20 photos were given the chance to vote for their favourite image. A panel of judges also chose three images that won jury prizes.

    Harris was also a competitor in NSERC’s Science, Action! research video contest,making the first cut of the three-round competition with her video “Jack Pine Growth, NT.”

    NSERC is Canada’s federal funding agency for university-based research, supporting faculty and students through a number of awards. In the most recent round of funding, 18 faculty researchers and nine students received a total of $3.2 million.
