These disparities hold critical implications for formulating scientifically grounded regional development strategies. Based on the three constituent elements of Marxist productive forces, this study employs the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) entropy method, Gini coefficient, and kernel density estimation to analyze the spatial-temporal evolution of MNQPF levels across China's coastal provinces using panel data from 2012 to 2021. The findings reveal:(1) China's MNQPF has shown an upward trend, yet its overall level remains relatively low;(2) Regional imbalances persist, with the Eastern Marine Economic Circle outperforming the Southern and Northern counterparts. Regional disparities primarily stem from inter-regional differences and super-variable density;(3) Spatial heterogeneity characterizes MNQPF development, manifesting as \"balanced growth in central regions vs. uneven development in northern and southern areas.\" In this regard, relevant discussion recommendations are put forward: (1) The Eastern Marine Economic Circle should leverage technological spillover effects to extend high-end marine industries northward to the Bohai Rim Economic Circle and southward to the Beibu Gulf Economic Zone;(2) The Northern Marine Economic Circle should advance green transformation of \"marine + heavy industry\" through port-economic belt construction under integrated land-sea development strategies;(3) The Southern Marine Economic Circle ought to enhance cross-border marine cooperation by capitalizing on its role as a \"Belt and Road\" hub, while strengthening Guangdong's radiating influence on neighboring provinces.","PeriodicalId":12479,"journal":{"name":"Frontiers in Marine Science","volume":"28 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143979867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Natural estuarine cycles of nocturnal hypoxia significantly reduce growth rates of North Atlantic bivalves","authors":"Jeffrey Kraemer, Christopher J.

During warmer summer months, these fluctuations are often intensified, potentially exposing local bivalve populations to repeated episodes of hypoxia. For this study, <jats:italic>in situ</jats:italic> flow-through experiments tested the effects of naturally-occurring nocturnal hypoxia on early life stage bivalves. Juvenile bivalves (hard clams, <jats:italic>M. mercenaria</jats:italic>; Eastern oyster, <jats:italic>C. virginica</jats:italic>; and bay scallop, <jats:italic>A. irradians</jats:italic>) were subjected to either natural estuarine cycles of DO and pH or amended, static normoxic but still acidified conditions during the peak cycling season (summer). Growth and survival rates of bivalves were quantified. During nine experiments across three summers, nocturnal hypoxia in unamend controls was moderate, with, on average, 3 hours per night of DO below 3 mg L<jats:sup>-1</jats:sup>, 1 hour per night of DO below 1 mg L<jats:sup>-1</jats:sup>, and a mean nocturnal DO concentration of 4.7 mg L<jats:sup>-1</jats:sup>. Still, amelioration of this nocturnal hypoxia during experiments yielded a mean increase in bivalve growth of 20% (range: 0 - 70%). Hard clams were more resilient to bouts of nocturnal hypoxia than scallops and oysters. The percent increases in growth rates of the hypoxia-ameliorated, aerated treatments were significantly correlated with hours of hypoxia during experiments (<jats:italic>p</jats:italic>&amp;lt;0.0001) and were significantly and inversely correlated with average nocturnal DO concentrations in control treatments (<jats:italic>p</jats:italic>&amp;lt;0.001). Application of these relationships to DO patterns at 19 sites across NY during summer indicated nocturnal hypoxia at these locales may have repressed bivalve growth rates by 10 – 240%. Given the enhanced predation pressure experienced by smaller bivalves, the slowed growth of unamended controls demonstrates that even small bouts of nocturnal hypoxia are a threat to estuarine bivalve populations.","PeriodicalId":12479,"journal":{"name":"Frontiers in Marine Science","volume":"123 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143979865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the initial phase of saltmarsh introduction, vegetation promotes the development of tidal networks, characterized by channel elongation, narrowing and deepening. However, under higher sediment supply, saltmarshes restrict sediment deposition on landward and central mudflats compared to that on unvegetated flats. Furthermore, sediment availability primarily facilitates the extension of pre-existing channels, while saltmarshes play a dual role in both generating new channels and elongating existing ones. This distinction highlights the competing mechanisms driving channel network development.","PeriodicalId":12479,"journal":{"name":"Frontiers in Marine Science","volume":"17 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143979854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The distribution of copper is strongly controlled by external inputs and physical dynamics, especially in marginal seas with benthic, fluvial, or aeolian sources. We present the spatial distribution of dissolved copper (dCu) in a quasi-zonal transect (25° N) spanning the Gulf of Mexico (GoM) from the Loop Current in the east to the continental slope in the west. The dCu profiles off the continental slope were recorded within a decaying anticyclonic Loop Current eddy (LCE) named Nautilus. In contrast, in the central GoM, dCu profiles were measured on the outside of LCE Olympus, which had recently detached from the Loop Current. The vertical distribution of dCu in the Loop Current was similar to that of the Atlantic Ocean, reflecting the origin of the water entering the GoM. High dCu concentrations in the surface waters of the central GoM were associated with dCu-rich freshwater inputs from the Mississippi River that were transported offshore (&amp;gt;400 km) by LCE Olympus. However, we identified a clear gradient of dCu in surface waters, with the dCu concentration increasing towards the region of LCE Nautilus in the western GoM. The vertical profiles of dCu in the LCE Nautilus also exhibited the highest dCu concentrations and were significantly greater than those of the adjacent Atlantic Ocean. This conspicuous enrichment of dCu was attributed to enhanced off-shelf transport by the decaying LCE Nautilus, in addition to benthic inputs from the continental shelf and slope, with atmospheric fluxes at the surface and the remineralization of organic matter in the water column playing minor roles. Our findings demonstrate that the interaction of mesoscale anticyclonic eddies with the continental margin acts as a mechanism for water exchange between the coastal zone and the deep-water region that is capable of shaping the spatial distribution of dCu in the GoM.","PeriodicalId":12479,"journal":{"name":"Frontiers in Marine Science","volume":"77 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143980087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
