We also just got another paper published, in which we outline a methodology for mapping wild leek using a small drone, based on work in Gatineau Park. Wild leek is a small plant that grows on the forest floor, so for most of the year it is impossible to map - in summer it is obscured by the tree canopy, in fall it has already lost its leaves, and in winter it is covered by snow... but for a short period in spring it is bright...

We don't do shallow water in my lab. In collaboration with friend and colleague Yongming Xu and others, we used coarse-resolution (MODIS) satellite data as well as point observations from weather stations in Tibet to map and monitor temperature trends across Tibet for the period 2001-2015. Below you see one result of that work - a map showing the 15-year mean near-surface air temperature across Tibet.

Compared to alternative da...

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 However, bathymetry data for the Canadian Arctic are frequently either outdated or unavailable.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...

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 bathymetr...
