Estuaries are vulnerable to oceanic and atmospheric climate change. Much of the research investigating change impacts on estuaries is focused saltwater intrusion within surface water due drought rising sea levels, with implications for ecosystems humans. Groundwater soil near may also be influenced, as estuary salinity hydraulic head changes can impact soils aquifers not previously at risk salinization. This study was conducted address knowledge gaps related present future groundwater distribution in a system connected macro-tidal estuary. The studied experiences tidal bore its connection Bay Fundy Nova Scotia, Canada. A parcel agricultural land adjacent selected assess response episodic fluctuations levels salinity. monitoring electromagnetic surveys were map patterns. numerical model flow solute transport informed by field data used investigate how varying droughts sea-level rise could Results showed that, contrast salt wedges observed along marine coasts, saline existed plume immediately around Model simulations that short-term had an insignificant However, permanent increases caused increased volume 86 %, or additional ∼11 m horizontally ∼ 4.5 vertically. Our results suggest river this setting would result widespread salinization porewater soils, but more extensive experienced permeable estuarine zones. Findings inform management decisions regions exposed future.

Surface waves generated during the crossing of post-tropical Hurricane Fiona (2022) over Gulf St. Lawrence, in Atlantic Canada, were simulated using a dynamically coupled wave and circulation model. Significant heights reached up to 9.4 m gulf, some largest possible this semi-enclosed coastal sea storm produced current speeds 1 s-1. Model results showed good agreement compared observations from buoy data, with low errors for significant height peak period. Broad-scale validation was completed across gulf seven different satellite altimeters. Detailed wind-generated back-barrier bay (Malpeque Bay) connected revealed by higher-resolution nested grid, which sheltered areas very short fetch 2 regions longer fetch. Currents reach 1.5 s-1 around barrier islands, contributions waves, winds, surge, tides driving flow. Limits wind-wave growth investigated analyzing differences between stationary nonstationary spectral computations, calculating spatial variability ratio translational speed celerity, inverse age. The indicate that Fiona, an extreme wind event large dominated locally-generated young sea, geographic scale limiting larger forming.
