Publikováno v: Botanica Marina. 63:43-59

The ability to map and monitor the macroalgal coastal resource is important to both the industry and the regulator. This study evaluates topo-bathymetric lidar (light detection and ranging) as a tool for estimating the surface area, height and biomas

Mercury Speciation and Distribution in Coastal Wetlands and Tidal Mudflats: Relationships with Sulphur Speciation and Organic Carbon

Autor: Nathan Crowell, João Canário, Nelson J. O'Driscoll, Tim Webster

Publikováno v: Water, Air, & Soil Pollution. 220:313-326

Sediment cores were analysed from four coastal wetland sites within the Minas Basin, Bay of Fundy to compare mercury speciation and sediment characteristics. The coastal wetland sediments were low in total mercury (mean = 17.4 ± 9.9 ng g−1); howev

Remote Predictive Mapping 7. The Use of Topographic–Bathymetric Lidar to Enhance Geological Structural Mapping in Maritime Canada

Autor: Tim Webster, Kate Collins, Nathan Crowell, Candace MacDonald, Kevin McGuigan

Publikováno v: Geoscience Canada. 43:199

An airborne topo-bathymetric lidar survey was conducted at Cape John, on the north shore of Nova Scotia, Canada, using the shallow water Leica AHAB Chiroptera II sensor. The survey revealed new bedrock features that were not discovered using previous
