    Aerial cetacean survey Southern Ocean 2019 (2023)
    PANGAEA
    Details
    Publication Date: 2023-10-28
    Description: This dataset was collected during PS119 during a dedicated distance sampling survey for cetaceans in the Southern Ocean conducted on board of Polarstern during the austral summer 2019 (25-04-2019 - 21-05-2019). Effort related sighting data were collected en-route using helicopter flights planned ad-hoc based on the current position of R/V Polarstern to infer density distribution of southern hemisphere fin whales. Surveys were conducted whenever wheather and ship operations permitted. One observer was seated on the port side of the helicopter and the data recorder was seated in the copilot seat on the port side. Positions were logged every 4 seconds using a dedicated survey software and all cetacean sightings were recorded upon detection. All changes that may impact detection probability of cetaceans were noted as described by the observers. Surveys were conducted at an altitude of 600ft at 100 kts and seastates less than 3 Bft This dataset contains all cetacean sightings recorded on track, including species, group size and effort related data including position (lat / lon) and datetime (utc format). All cetacean sightings were confirmed if possible (pending on fuel limitations and accessibility of the cetacean group) and comprise the number of animals in the group. Groups were defined as animals in close proximity at no more than two body lengths apart (not to be compared with e.g. acoustic groups that may stretch across hundreds of kilometers).

Effort related sighting data were collected along the ship track of R/V Polarstern to infer density distribution of southern hemisphere fin whales. Surveys were conducted whenever wheather and ship operations permitted. Surveys were conducted with 2 observers and one data logger from the crow's nest at ~ 29m ASL. Positions were logged every 4 seconds using a dedicated survey software and all cetacean sightings were recorded upon detection. All changes that may impact detection probability of cetaceans were noted as described by the observers. This dataset contains all cetacean sightings recorded on track, including species, group size and effort related data including position (lat / lon) and datetime (utc format). All cetacean sightings were identified using binoculars (if possible) and comprise the number of animals in the group. Groups were defined as animals in close proximity at no more than two body lengths apart (not to be compared with e.g. acoustic groups that may stretch across hundreds of kilometers). All detections were made using naked eye, binoculars were only used for species identification.

    The International Bathymetric Chart of the Southern Ocean Version 2 (IBCSO v2) (2022)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: The International Bathymetric Chart of the Southern Ocean Version 2 (IBCSO v2) is a digital bathymetric model (DBM) for the area south of 50° S with special emphasis on the bathymetry of the Southern Ocean. IBCSO v2 has a resolution of 500 m × 500 m in a Polar Stereographic projection (EPSG: 9354). The total data coverage of the seafloor is 23.79% with a multibeam-only data coverage of 22.32%. The remaining 1.47% include singlebeam and other data. IBCSO v2 is the most authoritative seafloor map of the area south of 50°S. IBCSO is a regional mapping project of the General Bathymetric Chart of the Ocean (GEBCO) supported by the Nippon Foundation – GEBCO Seabed 2030 Project. GEBCO is a project under the auspices of the International Hydrographic Organization (IHO) and the Intergovernmental Oceanographic Commission (IOC) with the goal to produce the authoritative map of the world's oceans. The IBCSO Project is also an integral part of the Antarctic research community and an expert group of the Scientific Committee on Antarctic Research (SCAR).

    Horizontal niche partitioning of humpback and fin whales around the West Antarctic Peninsula: evidence from a concurrent whale and krill survey (2016)
    SPRINGER
    In:  EPIC3Polar Biology, SPRINGER, 39(5), pp. 799-818, ISSN: 0722-4060
    Details
    Publication Date: 2017-01-20
    Description: A dedicated aerial cetacean survey was con- ducted concurrently to a standardised net trawl survey for krill in order to investigate distribution patterns of large whales and different krill species and to investigate relationships of these. Distance sampling data were used to produce density surface models for humpback (Megaptera novaeangliae) and fin whales (Balaenoptera physalus) around the West Antarctic Peninsula (WAP). Abundance for both species was estimated over two strata in the Bransfield Strait and Drake Passage. Distinct distribution patterns suggest horizontal niche partitioning of the two whale species around the WAP, with fin whales aggregating at the shelf edge of the South Shetland Islands in the Drake Passage and humpback whales in the Bransfield Strait. Krill biomass estimated from the concurrent krill survey was used along with CTD data from the same expedition, bathymetric parameters and satellite data on chlorophyll-a and ice concentration to model krill distribution. Comparisons of the predicted distributions of both whale species with the predicted distributions of Euphausia superba, Euphausia crystallorophias and Thysanoessa macrura suggest a complex relationship rather than a straightforward correlation between krill and whales. However, results indicate that fin whales were feeding in an area dominated by T. macrura , while humpback whales were found in areas of higher E. superba biomass. Our results provide abundance estimates for humpback whales and, for the first time, fin whales in the WAP and contribute important information on feeding ecology and habitat use of these two species in the Southern Ocean.

    Blue whale sightings in Antarctica west of the Greenwich meridian, January 2015 (2015)

    Details
    Publication Date: 2015-07-22
    Description: During the RV Polarstern PS 89 (ANT-XXX/2) expedition from Cape Town to Atka Bay and back, 20 sightings of 26 individual blue whales (Balaenoptera musculus) were recorded in Antarctic waters west of the Greenwich Meridian between 16-20 January 2015. These observations suggest a more westerly extension of a reported hot spot between the Greenwich Meridian and 20°E.

    Return of large fin whale feeding aggregations to historical whaling grounds in the Southern Ocean (2022)
    Nature
    In:  EPIC3Scientific repoorts, Nature, 12(9458)
    Details
    Publication Date: 2022-07-20
    Description: Fin whales (Balaenoptera physalus quoyi) of the Southern Hemisphere were brought to near extinction by twentieth century industrial whaling. For decades, they had all but disappeared from previously highly frequented feeding grounds in Antarctic waters. Our dedicated surveys now confirm their return to ancestral feeding grounds, gathering at the Antarctic Peninsula in large aggregations to feed. We report on the results of an abundance survey and present the first scientific documentation of large fin whale feeding aggregations at Elephant Island, Antarctica, including the first ever video documentation. We interpret high densities, re-establishment of historical behaviours and the return to ancestral feeding grounds as signs for a recovering population. Recovery of a large whale population has the potential to augment primary productivity at their feeding grounds through the effects of nutrient recycling, known as 'the whale pump'. The recovery of fin whales in that area could thus restore ecosystem functions crucial for atmospheric carbon regulation in the world's most important ocean region for the uptake of anthropogenic CO2.
