With near-complete replacement of Arctic multi-year ice (MYI) by first-year ice (FYI) predicted to occur within this century, it remains uncertain how the loss of MYI will impact the abundance and distribution of sea ice associated algae. In this stu

Satellite observations have revealed decreases in the duration of the seasonal snow and ice coverage of Great Slave Lake (GSL) and Great Bear Lake (GBL), large freshwater lakes in Northern Canada. However, limited information is available about ice t

Differentiating between first-year ice (FYI) and multi-year ice (MYI) in C-band synthetic aperture radar (SAR) imagery during spring–summer melt, when wet snow and melt ponds mask the underlying ice, is difficult. It has been suggested that the use

To better understand recent changes of Arctic sea ice thickness and extent, it is important to distinguish between the contributions of winter growth and summer melt to the sea ice mass balance. In this study we present a Lagrangian approach to quant

C-band synthetic aperture radar (SAR) imagery from RADARSAT-1 is used to estimate the equilibrium line of Devon Ice Cap, Nunavut, over 3 years (2004–2006). The equilibrium line is determined from the interpretation of radar glacier zones and the tr
