プロジェクトデータ
The TANGO1&2 expedition ventured to accumulate new data on the responses of marine ecosystems to shifts in ice regimes in the West Antarctic Peninsula (WAP), taking full advantage of a nimble sampling platform, the R/V Australis, a steel hulled, fully rigged motor sailer. TANGO1 took place between February and March 2023 and 2024, sampling two main locations at different spatial scales. Deploying 14 different types of gear (both traditional and modern), The use of R/V Australis for coastal studies deemed to be extremely efficient, in terms of environmental impact and reactivity, allowing the team to adapt the sampling efforts in function of the weather or anchoring conditions. Fully devoted to the expedition, the ship allowed the Tango team to sample in shallow areas, not accessible to icebreakers and too far away from research stations, and which have been under sampled.

収集方法
Continuous monitoring of birds and marine mammals (species identification and headcount) is performed from the bridge or a spot offering the best visibility on deck. Bird/mammal standard counts are 30 min non-stop observation with binoculars for identification (if required) and age/sex determination when possible. A 600 mm tele objective camera is used for documentation and identification of species that pose identification issues in the field (e.g. Catharacta spp., Pachyptila spp.). GPS ship position and climatic conditions are recorded at each start and end position of counts. Counts are performed during daylight (from dawn to dusk), while visibility permitting (counts must be stopped when visibility is poor due to heavy fog or precipitation) to avoid bias in animal detection and subsequent false population estimates. Equipment used for the survey: - Binoculars Leica Ultravid 10*32 - 600 mm Long lens SONY camera (XR10iv) - Garmin Oregon 600 GPS
| Study Extent | This dataset describes the abundance and distribution of SEABIRDS, MARINE MAMMALS of the WESTERN ANTARCTIC PENINSULA, DRAKE PASSAGE, MAGELLANIC AREA at ANTARCTIC PENINSULA, SOUTH AMERICA between February 14th 2023 to March 14th 2024 and from Feb.7th 2024 to March 5th 2024. |
|---|---|
| Quality Control | - All records were validated. - Coordinates were converted into decimal latitude and decimal longitude and plotted on map to verify the actual geographical location corresponds to its locality. - All scientific names were checked for typo and matched to the species information backbone of Worlds Register of Marine Species (http://marinespecies.org/) and LSID were assigned to each taxa as scientificNameID. - Event date and time were verified to be compliant with ISO 8601 standard. |

| Getting Started | Each sampling event that consists of a start coordinates and end coordinates is expressed as a LINESTRING in footprintWKT. The centroid of the LINESTRING is the decimalLatitude and decimalLongitude with coordinateUncertaintyInMeters that covers the full distance of the LINESTRING. Events with point location have POINT in footprintWKT with decimalLatitude and decimalLongitude with coordinateUncertaintyInMeters. coordinateUncertaintyInMeters include uncertainty estimated from the specification of the binoculars as the coordinates were measured from the GPS device and not the location of the occurrence of organisms. Similarly, temporal information can be found in the sampling event core under eventDate and eventTime. Species that were expected to occur during the expedition are listed under targetTaxonomicScope in the Humboldt Extension. Taxa listed in the Occurrence extension (vernacularName, scientificName, scientificNameID as well as the taxonomic classification) are the detections. Non-detections can be inferred by looking at taxa within targetTaxonomicScope that are not listed in the Occurrence extension. |
| 目的 | The main objectives of the continuous top predators inventories are, on one hand, to contribute to a better understanding of the mechanisms influencing the quantitative at sea distribution of seabirds and marine mammals in polar marine ecosystems (water masses, fronts, pack ice, ice edge and eddies) and, on the other hand, to detect spatial and temporal evolutions in these distributions with special attention to possible consequences of anthropogenic activity and global climatic changes. As seabirds and marine mammals constitute the upper trophic level in the food chain, their distribution reflects the abundance of prey, like zooplankton, krill, nekton and small fish, and is thereby an indicator for the ecology and biological production of the whole water column. Improved knowledge of this distribution patterns is therefore of high relevance and interest to identify and localize areas of high biological productivity, and to observe temporal changes due to anthropogenic influences and global change. Of several abiotic environmental factors, salinity and water temperature were identified as the most influential for bird distribution (Longhurst, 2007). Through monitoring across latitudes, areas of strong variations called transition zones which potentially correspond to borders between water systems or fronts indicating ecological discontinuities, were identified. Based on these considerations, the transects, conducted during the Tango expedition can be clustered into 3 main zones: Magellanic area, Drake passage, and Antarctic Peninsula. |
