Quality control (QC) of marine data is a critical aspect in ensuring the usability oceanic data. In this paper, we propose novel QC method for time-series ocean wave data, which combines deep learning prediction and statistical analysis. Our first realizes multi-element LSTM observation capturing both temporal consistency physical relationships between inputs. Then, it applies peak detection on regional mean difference ratio derived from predicted true values finally labels anomalous points based results. We conduct experiments four sites National Marine Science Center, China, compared our proposed with traditional that currently used operational quality control, as well classic anomaly models including Isolation Forest VAE-LSTM. The results show significant improvement Precision, Recall, F1 Score negative samples using method. takes advantages analysis considers correlation multiple elements effectively addressing problem erroneous discrimination abnormal sea conditions method, providing valuable insights study observational

The hot deformation behavior of a marine engineering steel for novel 980 MPa grade extra‐thick plate is investigated through compression tests at temperatures 850–1200 °C and strain rates 0.01–10 s −1 . flow stress curves are corrected to eliminate the effects friction on stress, modified constitutive model established accurately quantify behaviors steel. Hot working maps derived by using dynamic materials Prasad instability criterion. parameters recrystallization (DRX) nucleation mechanisms evaluated scanning electron microscopy backscatter diffraction. peak increased with decreasing temperature increasing rate, respectively. activation energy after correction 380.49 kJ mol DRX mechanism involves migration subgrains. optimized combining degree size recrystallized grain. optimum window determined as 1100–1200 0.1–10
