DIDSON Ultrasonic Video Data for Fish Behavior Near Survey Vehicles

DIDSON imaging sonar data collected to quantify fish avoidance or attraction biases relative to mobile sampling vehicles. The Northwest Fisheries Science Center's FRAM Marine Habitat Ecology Team built databases from information collected during the 2014 and 2015 field seasons, with ongoing analysis in 2016. The team planned further field research in the Southern California Bight for 2016.

Use Cases

• Quantifying fish avoidance behavior based on ultrasonic video data near mobile sampling vehicles.
• Analyzing fish attraction patterns relative to survey equipment mentioned in the description.
• Assessing biases in direct visual survey methods for fisheries research.
• Supporting the Untrawlable Habitat Strategic Initiative's research on marine habitat ecology.

Strengths

• Data originates from the NOAA Northwest Fisheries Science Center, an authoritative source.
• Includes data from two distinct field seasons (2014 and 2015).
• Available in both PDF and CSV formats, suggesting structured and documented outputs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality requires manual inspection after download.
