The paper introduces the Deep Zero-Inflated Bernoulli (DeepZIB) model, a deep statistical framework that jointly estimates latent North Atlantic Right Whale presence and detection probabilities from passive acoustic monitoring data. It addresses challenges such as zero inflation, imperfect detection, and complex habitat dependencies, and demonstrates improved predictive performance and model adequacy through simulations and real-world application along the U.S. East Coast. The model produces high-resolution, spatiotemporal presence maps that can inform targeted, risk-aware management of blue economy activities.

The paper presents a lightweight ResNet-based two-stage cascade for passive acoustic monitoring of killer whales. First, it detects vocalizations, then it classifies confident detections into five eastern North Pacific ecotypes, abstaining on ambiguous calls. The pipeline achieves high macro‑F1 scores on the DCLDE 2027 dataset and improves real‑time inference speed, while active learning adapts the detector to new acoustic environments.

AUWave is a hybrid deep‑learning framework that reconstructs high‑resolution regional significant wave height (SWH) fields from sparse buoy observations. By combining a station‑wise encoder with a multi‑scale U‑Net enhanced by self‑attention, it outperforms a baseline model, especially when more than one buoy is available, and identifies critical anchor stations through buoy ablation studies. Cross‑basin tests in the Atlantic and Pacific demonstrate the model’s robustness and portability, suggesting its applicability for operational ocean monitoring and data assimilation.
arXiv:2607. 16731v1 Announce Type: new Abstract: Marine biogeochemical forecasting is increasingly important for managing marine ecosystems and the carbon cycle, yet global, seasonal forecast products lag far behind physical oceanography, held back by the complexity of the processes involved and by data scarcity.
