Whilst inherently interconnected, much of the published work focuses on individual metocean environmental assessments. These valuable analyses were insufficient for robust ocean energy system design. This study proposes a methodology to examine the cotemporal characteristics of wave, wind, and current in an open-ocean environment. Based on a 25-year buoy observation dataset collected at a representative open ocean location off the coast of Oregon, USA, the cotemporal distributions of wind-wave and current-wave conditions are investigated over sea state histogram. The results show that the wind-wave magnitude correlation and directional alignment increases as wave height increases or wave period decreases, indicating the strongest wind-wave correlation at wave breaking sea states. The current-wave misalignment demonstrates an inverse relationship with wave period in wind-wave dominated seas but little dependence on wave period in swell-dominantly seas. Representative operational and extreme environmental conditions are identified using k-means clustering method and statistical analysis, respectively. Finally, numerical case studies on a floating ocean platform highlight the need to account for cotemporal environmental conditions in mooring loads and structural hydrodynamics analysis.</div></div>","PeriodicalId":419,"journal":{"name":"Renewable Energy","volume":"262 ","pages":"Article 125410"},"PeriodicalIF":9.1,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146186420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on this, N-heterocyclic deep eutectic solvents (DESs) were prepared using pyrazole and organic acids. Lignin extraction yield of 94.27% was achieved when pretreating corn stover at 145 °C for 180 min by pyrazole-formic acid DES (Py-FA), and >85% glucan was retained.
