“…Valdés in Patagonia, which has become a site of global significance for the conservation of marine mammals. Home to orcas, the site is also the world's most important breeding location for the endangered southern right whale (Nijs and Rowntree, 2017). A biosphere reserve rather than a whale sanctuary, it exhibits many of the features advocated within Challenges include the environmental impacts from various economic sectors, especially tourism, where whale watching has resulted in disturbances to sensitive breeding populations, and pollution from sewage treatment works, fish processing and industry located in the town of Puerto Madryn (Fazio et al, 2015;Chalcobsky et al, 2017;IUCN, 2017).…”

“…The unique pattern of callosities on the head of each right whale has been used since the 1970s to identify individuals and track their habitat use (Payne et al, 1983) in Península Valdés (Payne, 1986), Brazil (Payne, 1986), and South Africa (Best, 1990). In the Scotia Arc, researchers and tourists have opportunistically collected photo-IDs during marine mammal surveys (Jackson et al, 2020;Moore et al, 1999;Nijs & Rowntree, 2017) and eco-tourism trips to SG/IG since the 1990s. Over the last 5 years, there has been an increase in photo-ID records as a result of dedicated cetacean surveys (Jackson et al, 2020;Kennedy et al, 2020) and increasing engagement of citizen scientists with collecting SRW photographs and submission to the Happywhale website (https://www.happywhale.com; Cheeseman et al, 2017).…”

The sub‐Antarctic waters of South Georgia Island (Islas Georgias del Sur, SG/IG) are a regularly visited feeding ground for southern right whales (Eubalaena australis, SRW) in the southwest Atlantic. Satellite telemetry and photo‐identification records were compared to better understand the role of SG/IG in the SRW migratory network. We present the first insights from SRW satellite‐tracked from the SG/IG feeding ground, habitat use patterns in the Scotia Arc, and movements to Antarctic habitats. Photo‐identification comparisons to calving and feeding areas across the South Atlantic and a review of sightings of cetaceans reported from Bird Island (west of SG/IG) since 1979 illuminate long‐term habitat use patterns in SG/IG. We present the first recorded migratory movement between SG/IG and multiple countries: Argentina, Uruguay, and Brazil. Photo‐identification (1) linked SG/IG to a female SRW with a long‐term sighting history in Brazil, and (2) provided the first match between SG/IG and the western Antarctic Peninsula, suggesting the latter could extend the feeding area for southwest Atlantic SRW. Satellite tracking and opportunistic sightings suggest that shelf and coastal waters west of SG/IG represent an important multi‐season SRW feeding habitat and add to our overall understanding of habitats and ranges occupied by recovering southwest Atlantic SRW.

“…But Weir and Stanworth (2019) confirmed the presence of this species year-round in pelagic areas around the sub-Antarctic Falkland Islands peaking in austral summer. Summer and autumn SRW sightings are more regular now in the sub-Antarctic waters off South Georgia Island following the cessation of wha ling which occurred there between 1904and 1965(Ja ckson et al, 2020, and in the South Sandwich Islands (Zerbini et al, 2016;Nijs & Rowntree, 2017).…”

New sightings of the Southern right whales in West Antarctic Peninsula waters

Southern right whales (SRW) in the southwest Atlantic are recognized as slowly recovering after the massive population decline induced by harvesting. SRWs spend summer months in high-latitude feeding grounds and migrate to mid-latitude wintering grounds in autumn, where breeding occurs. Only a few sightings are known for the Antarctic waters as far south as 64° S. The West Antarctic Peninsula is a biologically productive area experiencing marine ecosystem transformations caused by climate changing at one of the fastest rates on Earth. The continental shelf of this region is important for krill stocks — a key prey source for SRW. The purpose of the present study was to reveal the austral summer and autumn presence of the SRWs in the waters of the West Antarctic Peninsula. In May—June 2009, vessel observations were made during a National Science Foundation research cruise. In March 2014, opportunistic surveys were conducted by researchers using the tour vessel as a platform of opportunity. During late March and April of 2018, January — July 2019 and March — April 2020, regular boat-based observations and vessel surveys were conducted in frames of the XXIII and XXIV Ukrainian Antarctic Expeditions, based at the Ukrainian Antarctic Akademik Vernadsky station. In our study we discuss four sightings of SRWs occurred at south of 64° S (2), and 65° S (2). On May 7, 2009, a single adult foraging SRW was sighted in Wilhelmina Bay. On March 22, 2014, an adult SRW was resting with two adult humpback whales in the northern part of the Lemaire Channel. On April 7, 2018, one SRW was sighted in a group with four humpback whales, and intensive interspecies social interactions happened. The last encounter of the SRW happened on April 24, 2020, in Gerlache Strait, near the southeastern coast of the Brabant Island — a single adult right whale was noticed while travelling. Results of our study indicate the autumn presence of some SRWs in the West Antarctic Peninsula waters — on the edge of the southern limit of known distribution for the species.
