The impact of ice structures and ocean warming in Milne Fiord Open
Arctic tidewater glaciers and ice shelves are undergoing rapid attrition, with warmer ocean temperatures playing an important role. However, the relationship between ocean temperature and ice structure retreat is complex and may change as …

Observations of Mixing and Deep Convection in a deep Fjord-Type Lake, Quesnel Lake, Canada Open
Deep lakes in temperate climates represent around 50% of the world’s surface, liquid freshwater storage, yet the mechanisms governing their seasonal deepwater renewal—and, in turn, their ability to support ecosystems—rema…

Investigating Upwelling Events in Multi-Arm Fjord-Type Lakes: A Case Study of Quesnel Lake Open
Lakes are an important part of the environment, being influenced by their inflows and influencing their outflows. The physical properties of lake water, such as temperature and dissolved oxygen concentration, affect downstream habitats and…

Heat Fluxes in a Glacial Fjord: The Role of Buoyancy‐Driven Circulation and Offshore Forcing Open
The ocean supplies large quantities of thermal energy to tidewater glaciers, but the mechanisms behind the heat delivery are not fully understood. To examine heat flux dynamics in glacial fjords, we run an 8‐year realistic numerical simula…

Unsteady Circulation in a Glacial Fjord: A Multiyear Modeling Study of Milne Fiord Open
The exchange of heat and freshwater between glaciers and the ocean is dictated by the circulation in glacial fjords and ice shelf cavities. Therefore, our ability to estimate and predict these fluxes depends on our understanding of the cir…

Annual pulses of copper-enriched sediment in a North American river downstream of a large lake following the catastrophic failure of a mine tailings storage facility Open
Failures of mine tailings storage facilities (TSF) can have profound and long-lasting effects on the downstream receiving environment. Virtually all spills to date have been into river systems without large lakes that may buffer downstream…

Initial Distribution and Interannual Decrease of Suspended Sediment in a Two‐Basin Lake Following a Massive Mine Tailings Spill: Quesnel Lake, BC, Canada Open
On 4 August 2014, a tailings dam failure at Mount Polley Mine in central British Columbia led to the largest short‐term release of mine waste into a lake ever recorded. Once released by the breach, slurry entered the smaller of Quesnel Lak…

Seasonal Turbidity Linked to Physical Dynamics in a Deep Lake Following the Catastrophic 2014 Mount Polley Mine Tailings Spill Open
The catastrophic August 2014 Mount Polley tailings spill, the second largest ever documented, sent ~18 Mm 3 of waste plunging to the bottom of the >100 m deep West Basin of Quesnel Lake, British Columbia, a critical West Coast salmon habit…

The baroclinic response to wind in a multiarm multibasin reservoir Open
Field data, a three‐dimensional hydrodynamic numerical model, and modal decomposition were used to examine the baroclinic response to wind in two interconnected multiarm lakes, Knewstubb and Natalkuz Lakes (British Columbia, Canada). Simil…

Seiche modes in multi‐armed lakes Open
The effect of multiple arms on standing wave patterns, or seiches, present within a lake is not easy to predict. This study examines free seiche modes in fjord‐type multi‐armed lakes in order to generalize features of the response of those…

Dynamic response of an Arctic epishelf lake to seasonal and long-term forcing: implications for ice shelf thickness Open
Changes in the depth of the freshwater–seawater interface in epishelf lakes have been used to infer long-term changes in the minimum thickness of ice shelves; however, little is known about the dynamics of epishelf lakes and what other fac…

Drift, drag and deterioration: mapping the fate of large ice hazards Open
Floating ice hazards are a risk to safe navigation in both the Arctic and the Southern Ocean as a result of changing ice conditions and increased marine traffic in recent years. These hazards include icebergs and ice islands (a type of ice…

The impact of a catastrophic mine tailings impoundment spill into one of North America's largest fjord lakes: Quesnel Lake, British Columbia, Canada Open
On 4 August 2014, a catastrophic breach of the Mount Polley mine tailings impoundment released ~25 M m 3 of tailings and water and scoured an unknown quantity of overburden into the West Basin of Quesnel Lake. We document Quesnel Lake and …

Axisymmetric circulation driven by marginal heating in ice‐covered lakes Open
Below the temperature of maximum density (TMD) in freshwater lakes, heating at the lateral margins produces gravity currents along the bottom slope, akin to katabatic winds in the atmosphere and currents on continental shelves. We describe…
