Abstract:

The biogeochemical cycling of carbon in Lochs Creran and Etive was investigated by using lignin as the biomarker for terrestrial organic matter. The oxygen uptake rate, percentage organic matter due to loss on ignition, Rp index, total carbon, total organic carbon (TOC), total nitrogen, C/N ratio, and phosphate content were used as the proxies to determine the biodegradability of the sediment organic matter. Total lignin in Lochs Creran and Etive ranged from 0.03 to 0.55mg/g, and Λ (mg/100mg OC) ranged from 0.37 to 0.98; the syringyl/vanillyl and cinnamyl/vanillyl ratios for both lochs ranged

Abstract:

This study investigates translocation of particulate carbon and nitrogen from burned and unburned catchments within New Mexico's Valles Caldera National Preserve following severe wildfire. My research questions are: (1) how much carbon and nitrogen is eroded from burned slopes and re-deposited in debris fans? and (2) how do these quantities compare to fluvial export of particulate carbon and nitrogen from nearby unburned catchments? Results indicate that the ~200 kg ha⁻¹ of nitrogen per depositional area on the debris fans represents ~50 to 100 years' worth of atmospheric inputs. In total, 124

Abstract:

Freshwater bodies have been long observed to become browner within the northern hemisphere. This brownification, has made drinking water production difficult, since increased organic content in freshwaters requires higher dosages of chemicals during water treatment. Changes in land use through increased industrial forestry, decreased sulphur deposition from reduced industrial emissions, changing patterns of hydrological and meteorological parameters resulting from climate change, including recently highlighted increase in iron concentrations have been proposed to explain brownification.

Abstract:

Societies are facing great challenges with obtaining a good quality and quantity of drinking water in the context of climate change. Increases in natural organic matter (NOM) and per- and polyfluoroalkyl substances (PFAS) have been observed in lakes and drinking water the past years, which is of great concern for water treatment plants in Sweden. It is therefore vital to increase the knowledge regarding the distribution of these substances in the environment. The main objective of this project was therefore to further develop a hydrodynamic model for lake Ekoln by including transportation and
