🤖 AI Summary
This study addresses the significant performance degradation of existing marine organism detection methods when deployed across diverse domains, which undermines the reliability of large-scale biodiversity monitoring. To tackle this issue, the authors propose a unified information pipeline that standardizes heterogeneous underwater data into comparable information streams and introduce a controlled cross-domain evaluation protocol to systematically assess detector robustness. Their analysis reveals that structural scene factors—such as target density and contextual redundancy—dominate performance loss more than visual degradation, leading to the identification of a “context collapse” failure mode. This insight motivates a structure-aware reliability paradigm. The resulting lightweight detection framework enables efficient inference on low-cost edge devices, demonstrating practical viability for remote monitoring and providing a consistent, scalable assessment tool for polar and Atlantic ecosystems.
📝 Abstract
Marine biodiversity monitoring requires scalability and reliability across complex underwater environments to support conservation and invasive-species management. Yet existing detection solutions often exhibit a pronounced deployment gap, with performance degrading sharply when transferred to new sites. This work establishes the foundational detection layer for a multi-year invasive species monitoring initiative targeting Arctic and Atlantic marine ecosystems. We address this challenge by developing a Unified Information Pipeline that standardises heterogeneous datasets into a comparable information flow and evaluates a fixed, deployment-relevant detector under controlled cross-domain protocols. Across multiple domains, we find that structural factors, such as scene composition, object density, and contextual redundancy, explain cross-domain performance loss more strongly than visual degradation such as turbidity, with sparse scenes inducing a characteristic"Context Collapse"failure mode. We further validate operational feasibility by benchmarking inference on low-cost edge hardware, showing that runtime optimisation enables practical sampling rates for remote monitoring. The results shift emphasis from image enhancement toward structure-aware reliability, providing a democratised tool for consistent marine ecosystem assessment.
