Permafrost hydrogeology Permafrost hydrogeology
Groundwater processes are often overlooked in permafrost environments, but subsurface storage and routing can strongly influence water and biogeochemical cycling in northern catchments. Groundwater flow in permafrost regions is controlled by the temporal and spatial distribution of frozen ground, causing the hydrogeologic framework to be temperature-dependent. Most flow occurs in...

Financial risk innovation: Development of earthquake parametric triggers for contingent credit instruments Financial risk innovation: Development of earthquake parametric triggers for contingent credit instruments
The Inter-American Development Bank (IDB) has developed financial risk management strategies for natural disasters focusing primarily on the emergency phase of the catastrophes where financial support is more cost-efficient and certainly most needed. The main IDB financial instrument to provide liquidity in the aftermath of catastrophic events is the Contingent Credit Facility (CCF). The...

Radiocarbon dating of tsunami and storm deposits Radiocarbon dating of tsunami and storm deposits
Radiocarbon age determinations can be an expedient and accurate means to assign age to deposits of tsunami or storm origin. Essential to the process of incorporating radiocarbon age determinations in tsunami or coastal storm investigations is an awareness on the part of the investigator that a sample will always return an age from a laboratory, but only carefully selected samples inform...

Vegetation sampling and management Vegetation sampling and management
What is the utility of vegetation measurements for wildlife managers? In the prairie, savanna, tundra, forest, steppe, and wetland regions of the world, mixtures of plant species provide wildlife with food, cover and, in some circumstances, water; the 3 essential habitat elements necessary to sustain viable wildlife populations. We define habitat in reference to use of a vegetation type...

Managing state lands for wildlife Managing state lands for wildlife
State-owned lands are a vital component of state fish and wildlife management programs because they contain valuable habitats for a diversity of wild species and often provide important public access. The Association of Fish and Wildlife Agencies (AFWA 2017) reported state agencies manage or administer approximately 188 million hectares of land, including 10 million hectares under fee...

The field trip that changed the course of my career The field trip that changed the course of my career
After gobbling down a breakfast of sliced papaya, scrambled eggs, refried beans, and soft flour tacos, we gathered our gear and loaded it into the red zodiac that the station manager had assigned to us. My colleagues and I were headed to a pair of islands off the coast of Belize called Twin Cays, occupied by a unique group of tropical plants and animals adapted to a wet and saline...
