Located a 30-minute helicopter ride away from Inuvik, NT, Trail Valley Creek supports many different long-term projects. My colleague, Vincent Graveline, and I were there for two weeks during which our goal was to launch weather balloons as part of Vincent\u2019s MSc research on planetary boundary layer dynamics. Attached to the balloons were detachable probes equipped with several instruments reading pressure, altitude and, most importantly, air temperature. Our goal was to observe the height of the planetary boundary layer in spring. The depth of the planetary boundary layer affects the land-atmosphere interactions, and its depth varies depending on land cover and atmospheric conditions. With the boreal tree line shifting northward, information on the planetary boundary layer over the tundra and a nearby forest stand will help to better understand the consequences of boreal treeline shifts on tundra-atmosphere interactions.<\/p>\n\n\n\n<p>A typical day could be split in three parts: the launch of the balloon, the wait for it to climb to a specific, pre-determined altitude and the retrieval of the probe. We walked over 70 km in the tundra, a radio receiver in hand looking for the white probe the size of a styrofoam cup with a single flashing LED light. This research trip allowed me to visit a changing arctic tundra research site where permafrost is rapidly thawing, a sight that I don&#8217;t normally see while modeling permafrost change from the comfort of campus. Science aside, the landscapes, the berries and the sneaky ptarmigans were worth all the soreness in our legs!<\/p>\n\n\n\n<p>Field work report by&nbsp;<a href=\"https:\/\/permafrostnet.ca\/fr\/people\/charles-gauthier\/\" target=\"_blank\" rel=\"noreferrer noopener\">Charles&nbsp;<\/a><a href=\"https:\/\/permafrostnet.ca\/fr\/people\/charles-gauthier\/\">Gauthier<\/a>.<\/p>\n\n\n\n<figure class=\"wp-block-gallery columns-3 wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\"><ul class=\"blocks-gallery-grid\"><li class=\"blocks-gallery-item\"><figure><img decoding=\"async\" width=\"1024\" height=\"498\" src=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220613_183851-1024x498.jpg\" alt=\"\" data-id=\"4981\" data-full-url=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220613_183851-scaled.jpg\" data-link=\"https:\/\/permafrostnet.ca\/20220613_183851\/\" class=\"wp-image-4981\" srcset=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220613_183851-1024x498.jpg 1024w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220613_183851-300x146.jpg 300w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220613_183851-768x373.jpg 768w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220613_183851-1536x747.jpg 1536w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220613_183851-2048x996.jpg 2048w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220613_183851-18x9.jpg 18w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220613_183851-scaled.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img decoding=\"async\" width=\"1024\" height=\"498\" src=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220614_005202-1024x498.jpg\" alt=\"\" data-id=\"4982\" data-full-url=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220614_005202-scaled.jpg\" data-link=\"https:\/\/permafrostnet.ca\/20220614_005202\/\" class=\"wp-image-4982\" srcset=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220614_005202-1024x498.jpg 1024w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220614_005202-300x146.jpg 300w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220614_005202-768x373.jpg 768w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220614_005202-1536x747.jpg 1536w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220614_005202-2048x996.jpg 2048w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220614_005202-18x9.jpg 18w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220614_005202-scaled.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img decoding=\"async\" width=\"1024\" height=\"498\" src=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220607_122909-1024x498.jpg\" alt=\"\" data-id=\"4980\" data-full-url=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220607_122909-scaled.jpg\" data-link=\"https:\/\/permafrostnet.ca\/20220607_122909\/\" class=\"wp-image-4980\" srcset=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220607_122909-1024x498.jpg 1024w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220607_122909-300x146.jpg 300w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220607_122909-768x373.jpg 768w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220607_122909-1536x747.jpg 1536w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220607_122909-2048x996.jpg 2048w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220607_122909-18x9.jpg 18w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/20220607_122909-scaled.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/li><\/ul><\/figure>\n\n\n\n<div class=\"wp-block-themeisle-blocks-advanced-columns has-2-columns has-desktop-twoOne-layout has-tablet-equal-layout has-mobile-collapsedRows-layout has-default-gap has-vertical-unset\" id=\"wp-block-themeisle-blocks-advanced-columns-a08fc886\"><div class=\"wp-block-themeisle-blocks-advanced-columns-overlay\"><\/div><div class=\"innerblocks-wrap\">\n<div class=\"wp-block-themeisle-blocks-advanced-column\" id=\"wp-block-themeisle-blocks-advanced-column-4ae214db\">\n<p><strong><strong>Scotty Creek Research Station by Rose Lefebvre<\/strong><\/strong><\/p>\n\n\n\n<p>In August, I went to the Scotty Creek research station in the Northwest Territories. As a modeler, being able to go to the field was a great opportunity: it allowed me to better understand one of the sites I am trying to model.<\/p>\n\n\n\n<p>The goal of my project is to simulate the climatic conditions of higher latitude regions, often underlain by permafrost, in a more accurate way. To achieve this, I will be including mosses in CLASSIC, the Canadian Land Surface Scheme Including Biogeochemical Cycles, as a plant functional type. Seeing Scotty Creek improved my understanding of just how much mosses are important in northern regions.<\/p>\n\n\n\n<p>I was in Scotty Creek to help with a drone data collection project: I climbed an eddy covariance tower to ensure there was always someone who could see the drone, while the drone pilot was back in camp. This allowed me to see the drone above the trees.<\/p>\n\n\n\n<p>I also took active layer depth measurements around the eddy covariance tower. This allows us to monitor permafrost thawing, which happens rapidly at Scotty Creek. We can see the impact it has on trees at the limit between the forested permafrost plateaus and the permafrost free bogs: they start to tilt from the instability of the ground.<\/p>\n\n\n\n<p>Field work report by&nbsp;<a href=\"https:\/\/permafrostnet.ca\/fr\/people\/rose-lefebvre\/\" target=\"_blank\" rel=\"noreferrer noopener\">Rose Lefebvre<\/a>.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-themeisle-blocks-advanced-column\" id=\"wp-block-themeisle-blocks-advanced-column-e014423a\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"576\" height=\"1024\" src=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/tower-selfie-576x1024.jpeg\" alt=\"\" class=\"wp-image-4986\" srcset=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/tower-selfie-576x1024.jpeg 576w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/tower-selfie-169x300.jpeg 169w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/tower-selfie-768x1365.jpeg 768w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/tower-selfie-864x1536.jpeg 864w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/tower-selfie-7x12.jpeg 7w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/tower-selfie.jpeg 1113w\" sizes=\"(max-width: 576px) 100vw, 576px\" \/><\/figure>\n<\/div>\n<\/div><\/div>\n\n\n\n<figure class=\"wp-block-gallery aligncenter columns-2 wp-block-gallery-3 is-layout-flex wp-block-gallery-is-layout-flex\"><ul class=\"blocks-gallery-grid\"><li class=\"blocks-gallery-item\"><figure><img decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/climbing-the-tower-768x1024.jpeg\" alt=\"\" data-id=\"4985\" data-full-url=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/climbing-the-tower.jpeg\" data-link=\"https:\/\/permafrostnet.ca\/climbing-the-tower\/\" class=\"wp-image-4985\" srcset=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/climbing-the-tower-768x1023.jpeg 768w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/climbing-the-tower-225x300.jpeg 225w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/climbing-the-tower-1153x1536.jpeg 1153w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/climbing-the-tower-9x12.jpeg 9w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/climbing-the-tower.jpeg 1428w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img decoding=\"async\" width=\"623\" height=\"777\" src=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/frost-probing.jpeg\" alt=\"\" data-id=\"4984\" data-full-url=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/frost-probing.jpeg\" data-link=\"https:\/\/permafrostnet.ca\/frost-probing\/\" class=\"wp-image-4984\" srcset=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/frost-probing.jpeg 623w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/frost-probing-241x300.jpeg 241w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/frost-probing-10x12.jpeg 10w\" sizes=\"(max-width: 623px) 100vw, 623px\" \/><\/figure><\/li><\/ul><\/figure>\n\n\n\n<p><strong><strong><strong>Engaging the Inuvik community\u00a0by Lyna Mansouri<\/strong><\/strong><\/strong><\/p>\n\n\n\n<p>For several scientists and students, the highlight of research is fieldwork. Sometimes, to&nbsp;produce high-quality data in permafrost-related research, the study sites can be isolated.&nbsp;Now, they are not only remote because they are north (from a southerner\u2019s perspective),&nbsp;but rather because they are secluded from the communities. For instance, the Trail Valley&nbsp;Creek (TVC) research station is situated north of Inuvik, NWT, in the middle of the tundra.&nbsp;As field season is extremely busy and dense, the researchers rarely have time to exchange&nbsp;and connect with local communities. They live and work out of the research station for&nbsp;most of the time they spend in the region. This poses the issue of creating a gap between&nbsp;researchers and community members. Indeed, it feels counterintuitive since research\u2019s&nbsp;primary goal is to inform decision-making and produce tools to build resilience for local&nbsp;communities.<\/p>\n\n\n\n<p>In the past year, thanks to funding from&nbsp;<a href=\"https:\/\/fsc-ccf.ca\/\" target=\"_blank\" rel=\"noreferrer noopener\">Future Skills Center<\/a>, NSERC PermafrostNet,&nbsp;<a href=\"https:\/\/ivado.ca\/en\/\" target=\"_blank\" rel=\"noreferrer noopener\">IVADO&nbsp;<\/a>and other sources, the situation is in remediation. During our fieldwork in TVC, my colleagues and&nbsp;I had the opportunity to work with several members of the community. One of our&nbsp;colleagues, Camellia, planned a marvellous barbecue with family and friends from Inuvik&nbsp;and, at last, scientists were stepping out of the research station and into building&nbsp;relationships with folks from the community. These kinds of activities and partnerships at&nbsp;the sites are concrete steps towards crafting research projects for, and with, the community&nbsp;and ultimately bridging the gap between scientists, students, and community members.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"805\" src=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/IMG_1960-1024x805.jpeg\" alt=\"\" class=\"wp-image-4993\" srcset=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/IMG_1960-1024x805.jpeg 1024w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/IMG_1960-300x236.jpeg 300w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/IMG_1960-768x604.jpeg 768w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/IMG_1960-1536x1207.jpeg 1536w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/IMG_1960-2048x1609.jpeg 2048w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/IMG_1960-15x12.jpeg 15w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/IMG_1960-scaled.jpeg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n\n\n\n<p><strong><strong><strong><strong>Finalizing a &#8220;nested&#8221; Arctic tundra flux set-up by Oliver Sonnentag<\/strong><\/strong><\/strong><\/strong><\/p>\n\n\n\n<p>After several years of planning, and delayed by the Covid-19 pandemic, the Sonnentag lab completed a &#8220;nested&#8221; Arctic tundra flux set-up (landscape > ecosystem > plot) at Trail Valley Creek Research Station near Inuvik, NT. The flux set-up comprises three eddy covariance (EC) towers, and automated and manual chamber systems. The 20-m landscape EC tower measures net carbon dioxide, methane, and latent and sensible heat exchanges between the terrestrial-aquatic landscape (including extensive shrub patches) and the atmosphere. Given prevailing wind characteristics, nested within the landscape flux footprint (i.e., the temporally varying source area) are a 5-m and a 7-m ecosystem EC towers, one &#8220;seeing&#8221; fluxes originating from polygonal tundra, or, depending on wind direction, a small lake, and one &#8220;seeing&#8221; fluxes originating from mineral upland tundra, respectively.\u00a0Nested within the ecosystem flux footprint (mineral upland tundra) is a custom-made chamber system to measure plot-scale net carbon dioxide\u00a0and methane\u00a0exchanges. The system comprises 18 automated chambers (nine \u2018transparent\u2019 and nine \u2018opaque\u2019 chambers), each with three replicates for three distinct plant communities: dwarf shrub, tussock, and lichen cover. Manual chamber measurements are collected from additional plant communities and land cover types (e.g., polygonal tundra and lakes). The chamber measurements are complemented by ancillary measurements of air and soil temperature, photosynthetic photon flux density, active layer depth, plant community composition, spectral characteristics, greenness, and soil moisture, temperature, and oxygen. Additional measurements to understand the underlying biogeochemical processes governing the carbon dioxide\u00a0and methane\u00a0sink-source behaviour: soil physical-chemical properties and gas profile dynamics, isotopic signal of d13C in soil carbon dioxide\u00a0and methane, soil pore water and lake nutrient concentrations, quality and microbial degradability of aquatic dissolved organic matter and microbial community composition. The goal of these comprehensive observations is to shed light on how tall shrub encroachment affects vegetation diversity and associated surface-atmosphere interactions across scales in the Southern Arctic ecozone of western Canada.<\/p>\n\n\n\n<figure class=\"wp-block-image alignwide size-large\"><img decoding=\"async\" width=\"1024\" height=\"297\" src=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/TVC_view_from_the_20m_tower-1024x297.jpeg\" alt=\"\" class=\"wp-image-4989\" srcset=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/TVC_view_from_the_20m_tower-1024x297.jpeg 1024w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/TVC_view_from_the_20m_tower-300x87.jpeg 300w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/TVC_view_from_the_20m_tower-768x223.jpeg 768w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/TVC_view_from_the_20m_tower-1536x446.jpeg 1536w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/TVC_view_from_the_20m_tower-2048x595.jpeg 2048w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/TVC_view_from_the_20m_tower-18x5.jpeg 18w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2022\/10\/TVC_view_from_the_20m_tower-scaled.jpeg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p><strong><strong><strong><strong><strong>Community training workshops in the NWT: Yellowknife (2 &#8211; 13 May) and Inuvik (6 &#8211; 9 September) by Oliver Sonnentag<\/strong><\/strong><\/strong><\/strong><\/strong><\/p>\n\n\n\n<p>The Sonnentag lab hosted two community training workshops this summer.
