In a recent article and short film produced by the Associated Press, Dr. Joe Pallin and Dr. Ari Friedlaender from UC Santa Cruz have provided their valuable insights on the critical issue of large-scale krill fishing in the Antarctic.
The article, titled “Factory fishing in Antarctica for krill targets the cornerstone of a fragile ecosystem.” and the accompanying film delve into the potential environmental repercussions of extensive krill harvesting in the Southern Ocean. Dr. Pallin and Dr. Friedlaender, known for their pioneering research on marine ecosystems, discuss how this practice could disrupt the delicate balance of the Antarctic ecosystem and threaten the survival of numerous wildlife species dependent on krill as a primary food source.
In the feature, Dr. Pallin explains, “Krill are the foundation of the Antarctic food web. Overfishing them could have cascading effects on the entire ecosystem, from the smallest microorganisms to the largest marine mammals.” His concern is echoed by Dr. Friedlaender, who adds, “We must consider the long-term impacts of our actions on the environment. Sustainable practices are essential to preserving these fragile ecosystems for future generations.”
The article and film highlight the need for stricter regulations and more comprehensive research to understand the full impact of krill fishing. They also emphasize the role of international cooperation in ensuring the sustainability of Antarctic marine resources.
Drs. Pallin and Friedlaender’s contributions to the discussion underscore their commitment to environmental conservation and their ongoing efforts to inform and influence policy through scientific research. Their work continues to play a vital role in raising awareness about the challenges facing our planet’s most vulnerable ecosystems.

On June 5, 2023, Science Focus published an article titled “How the Latest Tech is Shaping the Future of Whale Conservation,” featuring the groundbreaking work of Dr. Ari Friedlaender and his research team from the University of California, Santa Cruz. The article, authored by freelance journalist James Fair, elaborates on how the team utilizes advanced technology, including drones, suction-cup tags, and biopsy equipment, to gather crucial data on whale behavior in the Antarctic.
In the article, James Fair describes how the team employs drones to capture stunning aerial footage of whales, revealing intricate behaviors such as bubble-net feeding that are not easily observable from the water’s surface. These drones provide a unique perspective, allowing researchers to understand the precise movements and techniques whales use to corral and consume krill, their primary food source in Antarctica.
Dr. Friedlaender and his team also use suction-cup tags equipped with accelerometers and video cameras to track the whales’ movements and feeding habits over extended periods. These tags record data on the whales’ diving patterns, feeding lunges, and the environmental conditions they encounter, offering a comprehensive view of their daily lives and behaviors.
Additionally, the team employs biopsy equipment to collect small samples of whale skin and blubber. These samples are analyzed to assess the whales’ stress levels and reproductive status, providing valuable insights into their health and the impacts of environmental changes.
The article highlights the importance of this research in understanding and protecting whale populations. By utilizing cutting-edge technology, Dr. Friedlaender and his team are uncovering new information that can inform conservation efforts and help ensure the survival of these majestic creatures.

Our team has just finished an incredible field season in the Antarctic. We collected several hundred biopsies of whale tissue, paired many of these with measurable images of body condition using drones, placed tags on several animals, and conducted exposure experiments for a new study on the impacts of tourism on whale behavior. A film team from NowThis Earth joined one of our teams on an Intrepid Travel ship to tell our story.
The Antarctic Adventure
This past season has been a whirlwind of activity and discovery. Our primary goal was to understand the health and behavior of whale populations in the rapidly changing environment of the Antarctic Peninsula. As one of the fastest-warming regions on the planet, the Antarctic is experiencing dramatic shifts in sea ice coverage, directly impacting the availability of krill, the main food source for many whale species.
Biopsies and Body Condition
One of our major tasks was collecting biopsies from whales. These tissue samples are invaluable for studying the health, genetics, and diet of the whales. Paired with drone-captured images of their body condition, we can gain insights into how these majestic creatures are faring in their changing habitat. The drones allow us to get a comprehensive view of the whales’ physical state without disturbing them, providing a non-invasive method to monitor their health over time.
Tagging and Tracking
We also placed tags on several whales, which will help us track their movements and understand their migratory patterns. These tags provide critical data on how whales are navigating the increasingly ice-free waters and adjusting their feeding habits in response to diminishing krill populations. Understanding these patterns is crucial for conservation efforts, as it allows us to predict how whale populations might shift in the future and what measures can be taken to protect them.
Impact of Tourism
Another significant aspect of our research was conducting exposure experiments to study the impacts of tourism on whale behavior. The Antarctic Peninsula sees a growing number of tourists each year, and while tourism can raise awareness about the importance of this pristine environment, it also poses potential risks to wildlife. Our experiments aim to understand how close encounters with tourist vessels affect whale behavior and stress levels, which is vital information for developing guidelines to ensure that tourism remains sustainable and minimally invasive.
The Role of Whales in the Ecosystem
Whales play a critical role in maintaining healthy ocean ecosystems. They contribute to nutrient cycling by releasing fecal plumes that fertilize the ocean, promoting the growth of phytoplankton, which absorbs significant amounts of carbon dioxide. This process helps mitigate climate change by sequestering carbon in the ocean. Moreover, when whales die, their bodies sink to the ocean floor, providing a feast for deep-sea creatures and further contributing to the ocean’s carbon storage.
Our findings underscore the importance of protecting whale populations as a means of preserving ocean health and combating climate change. Whales are our allies in this fight, and their conservation is not just about saving these magnificent creatures, but about ensuring the future of our planet.
