MARC recordDetermining depth and ice thickness of shallow sub-Arctic lakes using space-borne optical and SAR data / C.R. Duguay, P.M. Lafleur.
| Title: | Determining depth and ice thickness of shallow sub-Arctic lakes using space-borne optical and SAR data / C.R. Duguay, P.M. Lafleur. |
| Author(s): | Duguay, C. R. Lafleur, P. M. |
| Date: | 2003. |
| In: | International Journal of Remote Sensing. (2003.), Vol. 24(3) (2003) |
| Abstract: | Presents approach for determining depth and ice thickness of shallow sub-Arctic tundra/forest lakes and ponds using Landsat Thematic Mapper (TM) and ERS-1 SAR data. Studies area in Hudson Bay Lowland near Churchill, Manitoba, Canada. Uses summertime Landsat TM image to estimate lake depth, followed by series of wintertime ERS-1 images to determine when and which lakes freeze to their beds during winter. Combines these derived products to estimate ice thickness on a monthly basis (maxima typically 1-2 m). Finds approach well-suited to shallow oligotrophic and ultra-oligotrophic lakes, but requiring improvement for lakes with high nutrient concentrations or suspended sediment loads. |
