Roundup: Seals, Flood Mitigation, and Freezing Levels

Seal Whiskers Detect Ecosystem Change

From Polar Biology: “Warm Atlantic water in west Spitsbergen have led to an influx of more fish species. The most abundant marine mammal species in these fjords is the ringed seal. In this study, we used isotopic data from whiskers of two cohorts of adult ringed seals to determine whether signals of ecosystem changes were detectable in this top marine predator.”

Flood Mitigation Strategies in Pakistan

From Natural Hazards: “The frequency and severity of flood events have been increased and have affected the livelihood and well-being of millions of people in Pakistan. Effective mitigation policies require an understanding of the impacts and local responses to extreme events, which is limited in Pakistan. This study revealed the adaptation measures adopted in Pakistan, and that the local policies on disaster management need to be improved to address the barriers to the adoption of advanced level adaptation measures.”

Rising Freezing Levels in Tropical Andes

From AGU Publications: “The mass balance of tropical glaciers in Peru is highly sensitive to a rise in the freezing level height (FLH). Knowledge of future changes in the FLH is crucial to estimating changes in glacier extents. Glaciers may continue shrinking considerably, and the consequences of vanishing glaciers are especially severe where people have only limited capacity to adapt to changes in the water availability due to, for instance, lack of financial resources.”
