Description
This dataset contains marine mammal observation data conducted during shipboard transects in the Chukchi Sea during the 5 August - 25 August 2017 Arctic Marine Biodiversity Observing Network (AMBON) research cruise. The dataset is two comma-separated values (csv) files exported from the marine bird and mammal observation software WinCruz from the entire survey. One data file contains the dates,times, latitude, longitude, species and best-high-low estimates of numbers for cetacean (whales) and pinniped (seals, seal lions, and walrus) sightings. The second data file contains the track of the ship (as geographic coordinates) and the Beaufort sea state at two minute intervals as a measurement of effort. This dataset was transformed from the native format into a table structure using Darwin Core Archive (DwC-A, occurrence core) term names as column names.
Data Records
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 112 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
