A breathtaking display of nature’s artistry has been captured on film, not by a Hollywood special effects team, but by a doctoral candidate using a drone. Jérôme lemelin, a physical oceanography doctoral student at the University of quebec at rimouski (UQAR), recently won both the jury prize and the public’s ”Discovery” prize in a prestigious Canadian science photography competition for his stunning images of the Saguenay Fjord.
Lemelin’s winning entry showcased a mesmerizing spectacle: hundreds of ice floes swirling in two massive, counter-rotating circles. this wasn’t just a visually stunning achievement; it was a significant scientific breakthrough. The meticulously crafted image, assembled from over 250 individual drone photos, provides invaluable data on surface currents within the fjord.
By analyzing the movement of the ice floes between frames of his video footage, Lemelin was able to calculate the speed of the currents. “By taking videos, from image to image, knowing how many seconds there are between each image, we know that the pieces of ice will have moved one meter from one photo to another. We are able to measure the speed of surface currents with this,” he explains.
The opportunity to gather this data arose unexpectedly. In March 2024, the Canadian Coast Guard broke up ice in the Saguenay fjord to improve navigation. Lemelin and his team seized this unique opportunity to study the resulting currents and their impact on the fjord’s ecosystem. This research contributes to a broader understanding of ice dynamics and their influence on marine environments, knowledge that has implications for similar waterways around the world, including those in the United States.
Lemelin’s work highlights the innovative use of drone technology in scientific research. His stunning images not only capture the beauty of the Saguenay Fjord but also provide crucial data for understanding complex environmental processes. This research underscores the potential of combining artistic expression with scientific inquiry to advance our knowledge of the natural world.
Saguenay fjord’s Ice Floes Reveal Ocean Secrets
Researchers in Quebec have made a breakthrough in understanding ocean currents using a surprisingly simple tool: a drone. Their study of ice floes in the Saguenay Fjord, a deep, narrow inlet on the St.Lawrence River, has yielded unexpected results, challenging previous assumptions about how these icy formations behave.
The team, led by Jérôme Lemelin, a doctoral candidate in physical oceanography at the University of Quebec at Rimouski (UQAR), initially hypothesized that the ice floes would passively follow surface currents.”We hypothesized that the floes,the pieces of ice,would perfectly follow the currents on the surface of the water,” explains Lemelin. Though, their observations using drone imagery revealed a different story.
The drone footage provided irrefutable visual evidence of the ice floes’ movement.Lemelin states, “We don’t need to ask ourselves any questions, we see that things work with the image.” This visual confirmation has significant implications for understanding the complex interplay between ice, water, and currents in the fjord, and possibly in other similar environments worldwide.
The findings from this research could have broader implications for understanding oceanographic processes globally.Similar studies in other regions with significant ice cover, such as the Arctic or Alaskan coastlines, could benefit from this innovative approach. The use of drones offers a cost-effective and efficient method for monitoring ice floe behavior, providing valuable data for climate change models and environmental impact assessments.
The Saguenay Fjord, a popular tourist destination known for its stunning natural beauty, is a unique ecosystem. Understanding the dynamics of its ice floes is crucial for protecting its delicate balance and ensuring the sustainability of its resources. This research highlights the importance of innovative technologies in advancing our understanding of complex environmental systems.
The Saguenay Fjord, a breathtaking waterway in eastern Canada, is revealing its hidden depths to researchers, who are uncovering a dynamic underwater world of powerful currents and dramatic wave formations. This natural laboratory, as researchers call it, is providing invaluable insights into oceanographic processes.
The fjord’s unique topography plays a crucial role in this underwater spectacle. Three significant underwater mountains, one rising over 65 feet below the surface near Tadoussac, create a complex interplay with the strong tidal currents. This interaction generates powerful whirlpools and significant underwater waves.
“It’s a bit like a natural laboratory,” underlines Jérôme Lemelin,a researcher involved in the study. The surface currents,while offering a glimpse into the deeper activity,only partially reveal the complex processes occurring below. The collision of surface waters with dense, salty deep water as it passes these underwater mountains is a key factor in the wave generation.
Cédric Chavanne, a physical oceanography researcher at the Institute of Marine Sciences (ISMER) of UQAR and co-director of the project, adds, ”Many underwater waves are generated there.”
this research not only enhances our understanding of the Saguenay Fjord’s unique ecosystem but also contributes to broader knowledge of oceanographic processes globally. The findings have implications for understanding similar underwater formations and current interactions in other coastal regions around the world, including potentially similar areas along the U.S.coastline.
The ongoing research in the Saguenay Fjord continues to shed light on the hidden forces shaping our oceans, highlighting the importance of studying these often-overlooked underwater landscapes.
Saguenay Fjord’s Unique Water Mixing: A Scientific Deep Dive
The Saguenay Fjord, a breathtaking natural wonder in Quebec, Canada, is the subject of a captivating new study revealing the intricate dance of underwater forces that shape its unique ecosystem. Researchers are exploring the complex interaction between underwater waves and swirling eddies, uncovering how these phenomena mix the fresh water of the Saguenay River with the salty waters of the St. lawrence river.
This mixing process is far from simple. “Afterward, these waves will have to interact with the eddies near the surface of the water, which are created by the change in direction of the currents when the tide rises, and which mix the surface waters, ‘like a kitchen mixer’,” explains researcher Mr. Chavanne.
The turbulence generated by these underwater waves and eddies forces water masses to rub against each other,creating a well-mixed water column. This is a crucial process for the fjord’s health, as Jérôme Lemelin, a doctoral candidate in physical oceanography, notes: “It’s a really cool opportunity to observe these two things at the same time and see how they interact.”
The Importance of Mixing for the Saguenay Fjord
Understanding these underwater dynamics is critical because they play a vital role in blending the distinct water masses of the Saguenay and St. Lawrence rivers. The Saguenay and St. Lawrence rivers exchange water with each tidal cycle, but complete mixing isn’t a frequent occurrence.
at depths of 250 meters, dense saltwater from the St. Lawrence lines the Saguenay’s internal basin. Without the action of underwater waves and eddies, this deep water would only be renewed onc a year during the highest tides, according to the researchers. However, thanks to the mixing, Mr.Chavanne points out, “Currently, they are renewed several times a year, thereby preventing the oxygen from being entirely consumed by underwater life.”
This contrasts sharply with the Laurentian Channel, were low oxygen levels are found near the channel’s head. The saguenay Fjord avoids these conditions due to its robust mixing processes. The Laurentian Channel, a deep underwater valley, experiences substantially less mixing, highlighting the unique characteristics of the Saguenay Fjord.

The irreversible nature of this water mixing is striking. Lemelin illustrates this by saying,”A bit like putting milk in coffee.” This process alters the water’s physical properties—temperature, salinity, and density. Though, he adds, “But we do not yet understand how exactly.”
Further research is needed to fully understand the intricacies of this natural phenomenon and its long-term implications for the delicate balance of the Saguenay Fjord ecosystem. The findings have implications for understanding similar estuarine environments worldwide and the importance of preserving these unique habitats.
Climate change Threatens saguenay Fjord’s Delicate Ecosystem
The Saguenay Fjord, a haven for marine mammals and a unique ecosystem, is facing unprecedented challenges due to climate change. Record low ice levels in the St. Lawrence River are disrupting the fjord’s delicate balance, raising concerns about the future of its rich biodiversity and the vital oxygen supply for its inhabitants.
Researchers are grappling with the complex interplay of underwater waves, whirlpools, and eddies that govern water mixing within the fjord. “Better understanding these whirlpools will allow us to deepen our knowledge of the processes of water renewal in the fjord,” explains a young researcher studying the phenomenon. This understanding extends beyond the Saguenay, offering valuable insights into broader oceanic processes.
The mixing of cold, oxygen-rich water from the St. Lawrence with the surface water of the fjord is crucial for marine life. This mixing is heavily influenced by the presence of ice, which forms a cold intermediate layer that persists throughout the summer. Though, the year 2024 witnessed the lowest ice cover ever recorded in the St. Lawrence River—a mere 6 cubic kilometers. This drastic reduction is attributed to warmer air and deep-water temperatures during the winter months.
Jérôme Lemelin, a doctoral candidate in physical oceanography, highlights the critical role of ice in this ecosystem. “If there is no more ice, this layer of water no longer exists, this changes many parameters such as the oxygen supply in the fjord,” he says. this oxygen depletion poses a significant threat to the fjord’s marine life, impacting everything from fish populations to the marine mammals that rely on the fjord for sustenance.
The Broader Implications of Ocean Change
The situation in the Saguenay Fjord reflects a larger trend of ocean change driven by climate change. Oceanologists have observed a slowdown in ocean currents in recent years, a phenomenon that could trap more heat in southern regions, leading to increased temperatures, rising sea levels, and more intense tropical storms. These changes, scientists warn, could fundamentally alter the oceans’ ability to recycle oxygen and nutrients, with far-reaching consequences for marine ecosystems worldwide.
The impact extends beyond the immediate environment. The disruption of the Saguenay Fjord’s ecosystem serves as a stark warning of the potential consequences of climate change on delicate marine environments across the globe, including those closer to home in the United States.Understanding the dynamics of this fjord is crucial for predicting and mitigating the effects of climate change on similar ecosystems.
Further research is needed to fully understand the long-term effects of reduced ice cover on the Saguenay Fjord and to develop strategies for protecting this vital ecosystem. The future of this unique environment hangs in the balance.

The research underscores the importance of detailed oceanographic studies in refining global climate models. These models, complex software simulations representing interactions between the atmosphere, ocean, ice, and Earth’s surface, rely on precisely determined parameters. These parameters are derived from mathematical equations based on the physical laws governing fluid mechanics.
the insights gained from the Saguenay Fjord study are not only scientifically significant but also hold practical implications for improving climate predictions and informing strategies to mitigate the effects of climate change. The research highlights the need for continued investment in oceanographic research to better understand and predict the future of our planet’s climate.
Ocean Waves and Eddies: A Key to More Accurate climate Predictions
Understanding the complex dance between ocean waves and eddies is crucial for improving climate models, according to a recent study. These underwater currents and wave interactions are far more intricate than previously understood, posing a significant challenge to accurately predicting future climate change.
Oceanographer Cédric Chavanne highlights the limitations of current climate models. He explains that the simplified formulas used to incorporate underwater waves need significant refinement. “The parameterization laws used to include underwater waves in a model should be more elaborate than they currently are,” he states.
The implications of this research extend far beyond the scientific community. More accurate climate models directly impact our ability to prepare for and mitigate the effects of global warming on the U.S. For example, improved predictions of sea-level rise could lead to better coastal protection strategies and more effective disaster preparedness planning.
“To predict climate change, we need to understand the ocean, and for that we need more reliable models that can predict how ocean circulation will evolve in the future with global warming.”
Chavanne’s statement underscores the urgency of this research. The accuracy of climate projections directly influences policy decisions related to everything from infrastructure progress to agricultural practices.The more precise our understanding of ocean dynamics, the better equipped we are to address the challenges of a changing climate.
This study, initially described as transforming a “simple ice ballet into a symphony of oceanographic knowledge,” represents a significant step forward in our ability to predict the future impacts of climate change. The improved understanding of ocean wave-eddy interactions promises to lead to more reliable climate models, ultimately benefiting communities across the United States and the globe.
