This webinar, titled The Impact of Wind on Groundwater Dynamics along a Microtidal Arctic Lagoon, will feature Julia Guimond, Assistant Scientist in the Department of Applied Ocean Physics and Engineering at Woods Hole Oceanographic Institution. The webinar will take place 26 April 2023 at 9:00 a.m. AKST/7:00 p.m. CEST.
Along coastlines worldwide, groundwater transports dissolved constituents to the coastal ocean, with implications for coastal carbon budgets and water quality. The magnitude and drivers of exchange along coastlines are not well understood, limiting assessments of present and projected coastal ecosystem health and function. In this seminar, Julia will discuss a recent field study focused on better understanding the drivers and magnitude of groundwater discharge along the Beaufort Sea coast of Alaska during open-period from July through September. Field data reveal that wind direction and speed drive fluctuations in sea level that exceed the tidal variability, impacting nearshore land-sea hydraulic gradients. In addition to diurnal fluctuations in hydraulic gradients that occur in tidally dominated environments, researchers find that elevated groundwater discharge was maintained for multiple days during periods of easterly winds. The data reveal that wind is the dominant factor impacting the magnitude of coastal groundwater discharge and local circulation along Arctic coastlines and suggest that wind can be used for first-order estimates of groundwater discharge along the Beaufort Sea coast.
