Many northern communities rely on up-to-date bathymetric information for safe ship passage between regions. However, bathymetry data for the Canadian Arctic are frequently either outdated or unavailable. Our research seeks to address this through satellite-derived bathymetry (SDB). In August 2017 we collected seafloor reflectance data from the west and east arms of Cambridge Bay, NU, as well as echo sounding data from the east arm. Using satellite imagery from Landsat 8 OLI,
It's official - we ran a Geomatics and Landscape Ecology field course in Zanzibar, 6-26 August 2018! The course focused on the application of GIS and Remote Sensing technologies to answer common questions in landscape ecology, especially regarding Zanzibar's coastal environment. The course was designed and co-taught with colleagues Martin Gullström and Lina Mtwana Nordlund as well as several researchers from the Institute of Marine Science in Zanzibar. Thanks to everybody who
In preparation for Shallow Survey 2018, we are testing how well a standard consumer-grade drone (Phantom 3 standard) can be used to map bathymetry in shallow and relatively clear water. In August 2017 we acquired a set of videos and coincident GPS feeds from five sites in Conception Bay, Newfoundland, and contributed them to the Common Data Set for the conference. We have then started to explore their use for mapping bathymetry in the areas where the seafloor is visible in th
Established in 2015, the Shallow Water Earth Observation Lab is still a new establishment, but we have been lucky to be supported by the Canadian Foundation for Innovation to set up some lab space and get some basic equipment in place. We're still building up our research infrastructure, but so far, the most important pieces of field equipment are: - Small inflatable boat with an electric outboard engine, as shown on the page banner. It's slow but portable and can comfortably
MSc, graduated November 2020. For her thesis, Kiyomi worked on satellite-derived bathymetry in Nunavut, comparing a range of empirical and physics-based methods across a range of satellite image types to assess their potential and robustness. She currently continues this as a Research Assistant.
MSc, graduated January 2020. Fiona worked on species distribution modeling for habitat-forming benthic organisms (corals and sponges) in the North Pacific. Her primary interest is to assess their sensitivity to climate-driven changes in ocean chemistry and currents. The oceans are useful indicators of climate change and its impacts upon ecosystems and species. Given the significant limitations in our understanding of the world’s oceans, predictive modeling of oceanic biogeoch
In early August 2017, Kiyomi and I went to Cambridge Bay, Nunavut, do collect some field data for her work on Satellite-Derived Bathymetry (SDB). It was the first time for us to travel to the Canadian Arctic, so pretty exciting for both of us! We stayed for free in a bright and roomy apartment associated with the brand new Canadian High Arctic Research Station (CHARS) run by Polar Knowledge Canada, which is an incredible facility for visiting researchers. Not only did Polar t
