There are few feelings quite so ecstatic as the joyful surprise when a humpback whale silently surfaces near your zodiac, and then fills the air with a krill-flavoured mist as it explosively exhales through its blowhole.&nbsp;<\/p>\n\n\n\n<p>Their recovery after years of exploitation is one of conservation\u2019s great success stories, but as more visitors head to the Antarctic Peninsula every year, it becomes ever more important to ensure that everything is done to protect them here. With this in mind, we look at how the polar cruise industry is taking new measures to do just that.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The role of Happywhale<\/h2>\n\n\n\n<p>Citizen science has been at the forefront of this move. For several years now, the Happywhale platform has been a key tool for those studying whale behaviour, particularly humpback whales. Humpbacks raise their tail flukes out of the water just before they dive, and each whale has a fluke that&#8217;s as individual as a fingerprint. By putting together digital photography and machine learning, Happywhale was able to create an open access database of individual whale sightings. It\u2019s thought that around a third of the global humpback whale population has now been recorded by Happywhale, making it an invaluable tool for marine biologists.\u00a0<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Humpback-Whale-Fluke-Charlotte-Island-Antarctica-November-2024-1024x576.jpg\" alt=\"\" class=\"wp-image-4737\" srcset=\"https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Humpback-Whale-Fluke-Charlotte-Island-Antarctica-November-2024-1024x576.jpg 1024w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Humpback-Whale-Fluke-Charlotte-Island-Antarctica-November-2024-300x169.jpg 300w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Humpback-Whale-Fluke-Charlotte-Island-Antarctica-November-2024-768x432.jpg 768w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Humpback-Whale-Fluke-Charlotte-Island-Antarctica-November-2024-1536x864.jpg 1536w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Humpback-Whale-Fluke-Charlotte-Island-Antarctica-November-2024-2048x1152.jpg 2048w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Humpback-Whale-Fluke-Charlotte-Island-Antarctica-November-2024-1200x675.jpg 1200w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Humpback-Whale-Fluke-Charlotte-Island-Antarctica-November-2024-1980x1113.jpg 1980w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Humpback flukes at Charlotte Bay in the Antarctica Peninsula<\/figcaption><\/figure>\n\n\n\n<p>Anyone going on an Antarctic cruise today is encouraged to take part in this massive citizen science project and upload their own photos of whale sightings to the Happywhale platform. As well as directly contributing to the database, you\u2019ll get notifications if \u2018your\u2019 whale is spotted elsewhere \u2013 and if the whale is a new addition to the database, you can even get to name it, in return for a donation to a whale conservation charity. At Swoop, we\u2019ve done<a href=\"https:\/\/www.swoop-antarctica.com\/blog\/supporting-whale-conservation-swoops-happy-humpback\/\"> just that<\/a>, and even had a former team member help discover a previously <a href=\"https:\/\/www.swoop-antarctica.com\/blog\/happy-whale-and-citizen-science-in-antarctica\/\">unknown migration route<\/a> for humpbacks between the Antarctic and the Caribbean.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Geofencing for whale safety<\/h2>\n\n\n\n<p>The thousands of humpback whale sightings recorded by expedition cruise passengers in Antarctica has been useful in another unexpected way. In 2019, enough data had been collected by the platform that it was used to propose creating a protected area in the Antarctic Peninsula where the whales were known to congregate. Members of the International Association of Antarctic Tour Operators unanimously adopted mandatory procedures in the Gerlache Strait and Crystal Sound areas, to reduce the risk of accidental ship strikes from vessels.\u00a0<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"584\" src=\"https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2023\/10\/Humpbacks-recorded-by-humpback-whale-in-January-2023-1024x584.png\" alt=\"Humpback whale data from Happy Whale\" class=\"wp-image-2313\" srcset=\"https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2023\/10\/Humpbacks-recorded-by-humpback-whale-in-January-2023-1024x584.png 1024w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2023\/10\/Humpbacks-recorded-by-humpback-whale-in-January-2023-300x171.png 300w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2023\/10\/Humpbacks-recorded-by-humpback-whale-in-January-2023-768x438.png 768w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2023\/10\/Humpbacks-recorded-by-humpback-whale-in-January-2023-1200x684.png 1200w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2023\/10\/Humpbacks-recorded-by-humpback-whale-in-January-2023.png 1279w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Humpback whale sightings recorded by Happywhale<\/figcaption><\/figure>\n\n\n\n<p>Two years later, these measures were strengthened even further, when operators committed to a mandatory 10 knot speed restriction, and new\u00a0 whale watching and whale avoidance mitigation training for all bridge teams when operating in any areas where whales are routinely seen. It was a great victory for whale conservation \u2013 particularly in the krill-rich feeding areas of the Gerlache Strait, which was once a hotspot for the <a href=\"https:\/\/www.swoop-antarctica.com\/blog\/governoren-shipwreck\/\">Antarctic whaling industry<\/a>, and is now regarded as one of the best locations in the region for whale watching.\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Global ship strike risk<\/h2>\n\n\n\n<p>Since the demise of industrial whaling, one of the biggest human threats to whale recovery has been accidental ship strikes \u2013 the technical term for any incident when a whale is hit by a vessel, leading to injury or even death.&nbsp;<\/p>\n\n\n\n<p>A recently published study in <a href=\"https:\/\/www.science.org\/doi\/10.1126\/science.adp1950\">the journal Science <\/a>mapped nearly half a million locations showing whale movement in four globally distributed species, and checked them against data for global shipping activity. The researchers&#8217; conclusions were stark: while shipping occurs across 92% of the ranges for humpback, fin, blue and sperm whales, fewer than 7% of whale hotspots have management strategies in place to reduce the chance of collisions. As global shipping continues to expand, it has become an increasing threat to the recovery of whales from centuries of exploitation.\u00a0<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"2400\" src=\"https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Whale-ship-strike-graphic-1.jpg\" alt=\"\" class=\"wp-image-4733\" style=\"width:600px\" srcset=\"https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Whale-ship-strike-graphic-1.jpg 1000w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Whale-ship-strike-graphic-1-94x225.jpg 94w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Whale-ship-strike-graphic-1-320x768.jpg 320w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Whale-ship-strike-graphic-1-768x1843.jpg 768w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Whale-ship-strike-graphic-1-640x1536.jpg 640w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2025\/01\/Whale-ship-strike-graphic-1-853x2048.jpg 853w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><figcaption class=\"wp-element-caption\">Predicted patterns of whale-ship collisions for blue, fin, humpback and sperm whales.

The majority of whale hotspots are found in national, rather than international waters, making the implementation of protection strategies potentially easier to implement. The reason for this is that the great whales prefer to congregate close to continental shelves, which are typically close to coastlines, since these are the most nutrient-rich waters in which to find food.&nbsp;<\/p>\n\n\n\n<p>By expanding management over just 2.6% of the ocean\u2019s surface, the report suggests, it would be possible to achieve full coverage of the world\u2019s whale hotspots. These strategies are also very simple, relating mainly to a ship\u2019s speed. Today\u2019s massive tankers simply don\u2019t give enough time for a whale to dive or get out of their way, but reducing a ship\u2019s speed to 10 knots can reduce whale mortality by <a href=\"https:\/\/www.frontiersin.org\/journals\/marine-science\/articles\/10.3389\/fmars.2021.649890\/full\">around a third<\/a>. Rerouting some shipping lanes to avoid whale hotspots is another strategy: when commercial vessels were moved away from the Hellenic Trench in the Mediterranean, a busy feeding spot for sperm whales, the collision risk was reduced by <a href=\"https:\/\/wwfwhales.org\/news-stories\/rerouting-shipping-traffic-to-safeguard-sperm-whales-in-the-eastern-mediterranean\">more than a quarter<\/a>.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Responsible whale watching<\/h2>\n\n\n\n<p>With statistics like these, it\u2019s vital that the Antarctic cruise industry plays its part in helping reduce the risk to these amazing animals that people travel so far to see.&nbsp;<\/p>\n\n\n\n<p>It\u2019s important to note that there is already <a href=\"https:\/\/iaato.org\/wp-content\/uploads\/2023\/08\/IAATO-Operational-Procedures-for-Watching-Whales-A3-Poster.EN_190180.pdf\">strict guidance<\/a> in place for whale encounters in Antarctica, that always puts the interests of the animal first.

Close encounters \u2013 such as those moments when a whale surfaces nearby must only ever be dictated by the animal. If you\u2019ve been out in the field, you\u2019ll also have noticed how guides stop their engines to avoid noise disturbance, and keep all encounters to a maximum of 30 minutes, again to avoid causing any unnecessary stress.&nbsp;<\/p>\n\n\n\n<p>These rules are even stricter when it comes to the ship. When there\u2019s a whale sighting, a ship must immediately cut its speed to five knots if within 400 metres (1300 feet) and idle its engines if safe to do so. Ships must never approach feeding whales closer than 200 metres (600 feet), and when moving away from an encounter must do so at a slow enough speed not to cause a wake \u2013 and never moving in front of the whales.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Expanding protection<\/h2>\n\n\n\n<p>The geofenced protection area runs from the new year to the end of May to coincide with the greatest concentration of whales during the summer season, and lasts until they migrate north in the Antarctic winter. Its successful adoption led IAATO to create the V-CaPS Programme in 2022 (the unwieldy name stands for Voluntary Cetacean and Pinniped Sightings), asking field staff to actively record whale sightings as well as seal sightings, along the western Antarctic Peninsula as well as up into the South Shetland Islands.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2024\/06\/36.-Fin-whales-feeding-in-South-Shetland-Islands-LW-Ocean-Nova-Dec-22-1024x576.jpg\" alt=\"\" class=\"wp-image-3911\" srcset=\"https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2024\/06\/36.-Fin-whales-feeding-in-South-Shetland-Islands-LW-Ocean-Nova-Dec-22-1024x576.jpg 1024w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2024\/06\/36.-Fin-whales-feeding-in-South-Shetland-Islands-LW-Ocean-Nova-Dec-22-300x169.jpg 300w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2024\/06\/36.-Fin-whales-feeding-in-South-Shetland-Islands-LW-Ocean-Nova-Dec-22-768x432.jpg 768w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2024\/06\/36.-Fin-whales-feeding-in-South-Shetland-Islands-LW-Ocean-Nova-Dec-22-1536x864.jpg 1536w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2024\/06\/36.-Fin-whales-feeding-in-South-Shetland-Islands-LW-Ocean-Nova-Dec-22-2048x1152.jpg 2048w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2024\/06\/36.-Fin-whales-feeding-in-South-Shetland-Islands-LW-Ocean-Nova-Dec-22-1200x675.jpg 1200w, https:\/\/www.swoop-antarctica.com\/blog\/wp-content\/uploads\/2024\/06\/36.-Fin-whales-feeding-in-South-Shetland-Islands-LW-Ocean-Nova-Dec-22-1980x1114.jpg 1980w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Fin whales near the South Shetland Islands<\/figcaption><\/figure>\n\n\n\n<p>\u2018IAATO operators have shared their whale and seal observations anecdotally for years,\u2019 Maureen Lynch, IAATO Resource Management Coordinator told us, \u2018But the V-CaPS programme provides a framework for Operators to follow, enabling them to collate this data more formally. This information then enables IAATO\u2019s membership to make more informed management decisions to protect Antarctica\u2019s wildlife\u2019<\/p>\n\n\n\n<p>Data collected through this programme has since been collated with existing scientific and historic data to expand protection even further. Whales sightings in the Gerlache Strait were once thought to be concentrated in the height of the austral summer, but the V-CaPS programme has led to the extension of the geofenced area to cover the entire Antarctic cruise season. In addition, the protected area has been expanded to cover the South Shetland Islands and Elephant Island. The latter carries particular symbolic significance, as one of the most popular of the islands to visit, <a href=\"https:\/\/www.swoop-antarctica.com\/blog\/a-guide-to-deception-island-antarctica\/\">Deception Island<\/a>, was once home to Antarctica\u2019s only shore whaling station.&nbsp;<\/p>\n\n\n\n<p>It\u2019s an encouraging picture.
