Effects of permafrost on groundwater constituent fluxes via submarine groundwater discharge in high latitude coastal environments

Numerous studies have quantified fluxes of groundwater constituents to coastal ecosystems and shown the importance of these fluxes. However, these studies are largely limited to mid and low latitude regions. Conditions unique to high latitude regions, such as permafrost and extreme tidal oscillations, have largely been ignored. This study seeks to better understand the effects of coastal conditions unique to high latitudes on constituent (nutrients, methane, metals, carbon) concentrations and fluxes in groundwater discharge to coastal oceans. Data from two high latitude sites where permafrost is continuous at the first and sporadic at the second will be presented.
