A team of 4 observers recorded 446 incidental seabird and cetacean sightings from Perth, Western Australia and return on the RV Investigator voyage IN2020_V01. The bulk of the observations is at Broken Ridge on the edge of the Kerguelen Plateau. Voyage details, reports and other datasets are at https://www.marine.csiro.au/data/trawler/survey_details.cfm?survey=IN2020_V01

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).

Seabird and incidental cetacean and seal sightings were recorded during daylight hours during the moorings deployment, offshore from Brisbane, Nov 2016. Observations were made every ten minutes in the forward quadrant. There were 410 observations from 20 species of birds and one cetacean. The commonest bird species were Puffinus pacificus and Sterna bergii. 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).

Seabird and incidental cetacean and seal sightings were recorded during daylight hours during the moorings deployment at the SOTS site, southwest of Tasmania, March 2017. Observations were made every ten minutes in the forward quadrant. There were 1200 observations from 38 species of birds, 3 cetacean species and one seal. The commonest bird species were Puffinus tenuirostris and Pachyptila turtur. 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).

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.

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).

This record is an overview entry for biological data collected on Soela cruise SO 5/85. This cruise took place in waters off the Tasmanian coast, Bass Strait, Victorian, New South Wales and Queensland coasts during 12 September - 9 October 1985, under the leadership of Barry Bruce and Brian Griffiths. Biological data collected on this cruise include Blue Grenadier larvae from Sandy Cape to Storm Bay. Samples of ripe Blue Grenadier males. Taxonomic specimens from a deep shot to a depth of 1250 m north of Sandy Cape. Some specimens including a frill shark, two small seven gill sharks and two Schedophilus huttoni from the 12 demersal shots for MSL. One dogfish, and one trevalla sample. Seabird observation data and bird census at Cato Island. Biological oceanography data from temperate and subtropical waters.(derived from the cruise report) - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.

This record describes the datasets obtained on Courageous Cruise 047. The data were obtained from the Great Australian Bight in March and April 1979. Data were obtained from acoustic and trawl surveys of pelagic and demersal fish. New species distributions were obtained for fish including the footballer sweep (Neatypus obliquus), stargazer (Pleuroscopus psuedodorsalis), and various myctophids. Four species from trolling included Bonito (Sarda orientalis), Southern bluefin tuna (Thunnus maccoyi), Albacore (Thunnus alalunga) and Skipjack tuna (Katsuwonus pelamis). Length, numbers, weight and target signal strength were determined. Selected species of sponges were kept for taxonomic studies. Plankton observations were made in connection with studies of the distribution of pilchard (Sardinops neopilchardus). Additional information regarding this dataset is contained in the cruise summary for this voyage.(derived from the cruise report) - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.
