Si el cambio climático anula el ciclo estacional de hielo y deshielo, se desencadenaría un ciclo de retroalimentación de derretimiento del hielo marino en algunas partes del Ártico canadiense.

An Inclusive Approach to Oceangoing Research
The bread and butter of oceanography, sea voyages rarely include minoritized communities and nonscientists. The Inclusion Mission wants to change that.
High-Frequency Monitoring Reveals Riverine Nitrogen Removal
Years of daily readings provide an unprecedented view into how a submerged aquatic meadow kept nitrogen from reaching the St. Lawrence Estuary as well as insights on how climate change may alter it.
Exploring Carbon Emissions in Peatland Restoration
Rewetting bogs can increase methane emissions in the short term, but ultimately the approach helps restore peatlands and create larger carbon sinks.
The Fate of a Lake After a Dramatic Mining Disaster
Researchers tracked long-term sediment dynamics in Canada’s Quesnel Lake following the 2014 failure of a dam that spilled record-breaking amounts of contaminated mining waste.
Searching for Earth’s Oldest Rocks in its Youngest Deposits
By sampling and analyzing zircons from glacial eskers dating from about 20,000 years ago, the extent of the oldest known rocks on Earth can be better mapped and constrained.
Tracing Water Particles Back in Time
Every summer, a low-oxygen pool settles off Canada’s western coast. A new study uses robust modeling to track the origins of the dense water.
Good or Bad Jam? Modeling Boulders’ Fate at Constrictions
A new modeling framework to assess the likelihood of jamming at constrictions can be used to support the design of effective mitigation measures and reduce risk in debris flow prone areas.
Groundwater Flow May Contribute to Submarine Permafrost Thaw
New, detailed surveys from the Beaufort Sea reveal a seafloor depression the size of a city block associated with permafrost thaw and likely influenced by the movement of groundwater below.
Predicting Discharge Chemistry in Mine-Waste Rocks
Quantifying integrated hydrological processes, biogeochemical reactions, and mineralogical characteristics can help predict water quality and quantity for mine-waste rock piles.
