Monitoring of reef fish abundance in the Tsitsikamma National Park using stereo-BRUVs

Latest version published by The South African Institute for Aquatic Biodiversity on Jan 2, 2020 The South African Institute for Aquatic Biodiversity

Stereo-BRUVs were deployed in Tsitsikamma National Park to monitor reef fish abundance and measure fish lengths. The resultant records of sampling events, underwater videos, fish occurrences and fish lengths constitute this dataset. Videos were analysed using EventMeasure (SeaGIS) to record MaxN and length values. See Bernard et al. (2014). DwC Event Core: A parent sampling event represents an event that took place at a named location, where a number of child sampling events (videos) were undertaken. DwC Occurrence Extension: An occurrence record represents a species observed in a particular 60-minute video, specifically the MaxN, or largest number of individuals of this species observed in a single frame. DwC Extended Measurement or Fact Extension: Each record represents an individual fish, specifically the individual's length as measured using EventMeasure. DwC Audubon Media Description: Each record represents a child sampling event's video file (video files are not available online but can be requested).

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 187 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.

  • Event (core)
    187
  • Occurrence 
    1442

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.
