Recent research has confirmed that satellite altimetry can be used for detecting icebergs. In an effort to validate the altimetry-based approach, this study used 105 samples of icebergs contained in both satellite altimeter data and ENVISAT-ASAR scenes for the Weddell Sea area. The probability of detecting icebergs larger than 150 m waterline-length was 47%. The problem of discriminating ships and...
Mapping iceberg locations and geometrical parameters is important for marine operational applications and climate science. The innovative TanDEM-X mission (TDM) was used for 3D mapping of icebergs in sea ice with the single-pass SAR interferometry (InSAR) method. The extracted digital elevation model (DEM) from TDM InSAR data over icebergs in sea ice was compared to a DEM generated from very-high-resolution...
Dissolved oxygen (DO) levels were monitored in two marine Atlantic salmon (Salmo salar L.) cage sites on the south coast of Newfoundland (Canada) during the summer and fall of 2008 and 2009. In 2008, sites A and B had cages with stocking densities of approximately 9 kg m−3. In 2009, site A was being fallowed while stocking density at site B was of 10 kg m−3. During 2008 and 2009, few hypoxic events...
