Graduate Exit Seminar- Chloe Turner
Chloe Turner will present Soil Chemical Properties Dynamics in Glacial Moraines Across a Chronosequence: Breiðamerkurjökull, Iceland at 1:00 P.M. on Friday, April 13th in Kottman Hall room 245.
The foreland of retreating glaciers are areas of newly-exposed deglaciatedterrain, which are exposed to the environmental processes of plant and soil succession. The foreland of the Breiðamerkurjökullglacier serves as a chronosequenceto study the morphological, physical, and chemical changes of the soils. On the moraines, evidence of the influence of seabirds was observed by the formation of hummocks. This study supports the hypothesis that point-centered input of seabirds into the soil landscape can locally enhance the chemical properties, nutrient availability and rates of soil formation. This presentation will discuss the results of chemical and nutrient analyses across the developing moraine soils of Breiðamerkurjökull, Iceland.
