RV Investigator Voyage IN2016 V01 Seabird Observations
Seabird and incidental cetacean and seal sightings were recorded during daylight hours during the entire voyage. During the voyage, there was 2,581 transect counts of seabirds of 61 species. Coverage was good over the area around Heard and McDonald islands, with some coverage also of Gunnari Ridge. Also covered some deeper parts of the Central Kerguelen Plateau. There were 31 sightings of sea mammals away from the immediate vicinity of Heard and McDonald islands (fur seals were sufficiently common in waters around Heard and McDonald Island to be treated using the same method as for seabirds). Sightings included five species of whales and three species of dolphins. The most intriguing series of sightings comprised seven sightings (approximately eight animals) of blue whales over Gunnari Ridge on 9/10 February (another sighting on 21 January may have been in the same area, as it was approximately 1° north and 1° west of the February sightings) The data has been published to the Ocean Biodiversity Information System (OBIS https://obis.org).

RV Investigator Voyage IN2016 T02 Seabird Observations
공공데이터포털
Seabird and incidental cetacean and seal sightings were recorded during daylight hours during the transit from Hobart to Sydney, May 2016. This voyage was used as a trial of acquiring observations from the RV Investigator observation deck and testing the data recording system. Observations were made every ten minutes in the forward quadrant. There were 393 observations from 33 species of birds, 3 cetaceans and one seal. The commonest bird species were Pachyptila turtur, Thalassarche cauta, Sterna bergii and Morus serrator. Each species has been linked where possible to the World Register of Marine Species (WoRMS https://www.marinespecies.org). The data has been published to the Ocean Biodiversity Information System (OBIS https://obis.org).

RV Investigator Voyage IN2019 V03 Cetaceans and seabirds along the Indian Ocean 110°E meridian (Second International Indian Ocean Expedition (IIOE-2) expedition)
공공데이터포털
The aim of this study, as part of a large number of related studies, was to examine the occurrence of cetaceans and seabirds along the 110◦E meridian from temperate to tropical waters (39.5–11.5◦S). Cetaceans and seabirds were actively scanned for across a four-week period spanning austral autumn to winter. Acoustic recordings of vocalising cetaceans weremade using directional and omnidirectional sonobuoys (n = 87 deployments). In total, seven cetacean sightings (six baleen whale, one toothed whale), 186 seabird sightings and 225 cetacean acoustic detections were recorded. A total of 22 seabird species were sighted, including, petrels, albatrosses, tropicbirds, terns, shearwaters, boobies, frigatebirds, gannets, gulls, skuas and prions.
