Timor Sea Fish and Benthic Survey with 1465 Individuals

Timor Sea CMR survey recorded 1465 individual fish, sharks, rays, and sea snakes from 85 species using 47 baited remote underwater video stations (BRUVS). The dataset includes 504 images and records habitat classification, species identity with CAABCODES, arrival time, behavior, maturity, and relative abundance (MaxN). Data was collected from September 12 to October 6, 2012, by the Australian Ocean Data Network.

Use Cases

• Analyze species distribution and relative abundance (MaxN) across different benthic habitat classifications.
• Model fish arrival time and feeding behavior patterns using the 8 recorded behavior categories.
• Classify species maturity (adult or juvenile) based on visual characteristics from the 504 images.
• Study population dynamics by linking CAABCODES for species identity with MaxN counts across the 47 video stations.

Strengths

• Contains observations for 1465 individuals from 85 distinct species.
• Data collection utilized 47 baited remote underwater video stations, providing standardized sampling.
• Includes 504 images for visual verification and analysis of species and habitat.

Limitations

• Dataset size is relatively small, with only 1465 individual observations recorded over a short 25-day period.
• Data is from 2012 and may not reflect current marine population or habitat conditions in the Timor Sea.
• Specific column definitions and the full data structure are not provided, complicating direct analysis.
