There is often a temporal bias between the SS-derived and actual POC fluxes caused by neglecting the temporal change in <jats:sup>234</jats:sup>Th. However, this temporal bias has not been fully investigated due to the lack of continuous sampling of <jats:sup>234</jats:sup>Th profiles and sediment traps. Here, we develop a radioactive trace model of <jats:sup>234</jats:sup>Th built on a physical–biogeochemical model to simulate the scavenging of <jats:sup>234</jats:sup>Th in the water column by POC sinking processes at the South East Asia time series (SEATS) site. The seasonal patterns of the <jats:sup>234</jats:sup>Th profiles simulated by the model generally compared well with <jats:italic>in situ</jats:italic> observations. Analysis based on the model simulation suggests that the temporal bias can be depicted and reproduced in a simplified <jats:sup>234</jats:sup>Th continuity equation. By obtaining an analytical solution for the SS-derived POC flux from the simplified <jats:sup>234</jats:sup>Th equation, we found that the temporal bias results from the phase difference in time between the SS-derived and direct sinking POC fluxes. To provide a method that does not need repeated samplings to reduce this temporal bias for <jats:italic>in situ</jats:italic> observations, a modification term was constructed for the SS-derived POC flux from the analytical solution. Applying this term to the data obtained at the Bermuda Atlantic time series and SEATS reduced the bias by up to 67% and 34%, respectively. This study provides a feasible way to improve <jats:sup>234</jats:sup>Th-derived POC flux under the SS assumption.","PeriodicalId":12479,"journal":{"name":"Frontiers in Marine Science","volume":"73 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766956","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 <jats:italic>Megalaspis cordyla</jats:italic> an economically important fish species in Pakistan, require an accurate assessment of its current biomass to take effective management strategies. This study utilized stock assessment techniques, including the Catch-Based Monte Carlo Maximum Sustainable Yield (CMSY), length-based Bayesian Biomass (LBB), Just Another Bayesian Biomass Assessment (JABBA), and ARIMA models. While CMSY, BSM, JABBA, ARIMA rely on annual catch-effort data, while LBB analyzes length-frequency data along with resilience inputs. An analysis of 15 years of catch data (2007-2021), and 1,442 length-frequency data from Pakistani waters revealed that the fishery is overfished both in terms of exploitation and biomass (LBB at <jats:italic>F/M</jats:italic> = 1.6, <jats:italic>B/B<jats:sub>MSY</jats:sub></jats:italic> = 0.76 and <jats:italic>B/B<jats:sub>0</jats:sub></jats:italic> = 0.27). The CMSY method estimated biological reference points as r = 0.53, k = 231, and a maximum sustainable yield (MSY) of 3.06. In comparison, the BSM provide values of r =0.03, k =271, MSY = 2.56. The JABBA model estimated MSY of 3.637, with a biomass to MSY<jats:sub>2021</jats:sub> (B<jats:sub>2021/</jats:sub>B<jats:sub>MSY</jats:sub>) of 0.68 and F<jats:sub>2021</jats:sub>/F<jats:sub>MSY</jats:sub> of 1.56, indicating excessive exploitation. The projected biomass ratio (B<jats:sub>2021</jats:sub>/B<jats:sub>MSY</jats:sub>) of 0.798, is&amp;lt;1, confirms overexploitation. Additionally, the ARIMA (2, 0, 1) model, demonstrated the lowest mean square error, predicts a significant upward trend in fish catches in the near future. The findings across all models consistently indicate that the <jats:italic>M. cordyla</jats:italic> fishery is overfished, with current catches exceeding sustainable limits. Biological reference points from CMSY, JABBA, and LBB models, all below 1.0, underscore the unsustainable of the fishery. If current trend continues, the fishery faces a substantial risk of collapse. To mitigate this, immediate management measures should be implemented to promote the sustainable utilization of this critical fishery resource in Pakistan.","PeriodicalId":12479,"journal":{"name":"Frontiers in Marine Science","volume":"41 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766350","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}

In areas where ocean depths exceed 50 meters, conventional permanent foundations become economically unfeasible, becoming floating offshore wind turbines (FOWTs) a superior alternative. Simultaneously, the development of marine resources in offshore areas has failed to meet increasing market demand, necessitating the urgent expansion of aquaculture fisheries into deeper waters. This research developed a fully integrated model of a cage platform, net system, and mooring system, compatible with the NREL 5MW wind turbine. Numerical simulation methods, based on potential flow theory and Morrison’s equation, are utilized to examine the motion response characteristics of the coupled system under various sea conditions. The study results demonstrate that the net, acting as a damping element, significantly decreased the system’s motion response and enhanced its stability. The system’s dynamic response is influenced by wave height and period in both regular and irregular wave circumstances, particularly under extreme sea conditions. Furthermore, the net’s presence minimally affects the wind turbine’s power output while contributing to the mitigation of power fluctuations. The examination of complex environmental circumstances influenced by wind, waves, and currents reveals that a rise in current velocity markedly changes the system’s surge motion trend, although it has little impact on power output. The work establishes a theoretical framework for the design and optimization of deep-sea wind-fishery integrated systems, providing insights into the maximization of marine resource utilization and the commercial deployment of wind energy.","PeriodicalId":12479,"journal":{"name":"Frontiers in Marine Science","volume":"58 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143757749","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}

Melting of Northern Hemisphere ice sheets would have led to a southward shift of the Intertropical Convergence Zone (ITCZ) and reduced transport of warm surface waters from the low latitudes to the Northern Hemisphere high latitudes.

For brittle stars, a class of echinoderms that dominate the megabenthos in various marine systems due to their often large populations, including those on Arctic soft bottom shelves, growth and longevity information can be estimated through growth bands in their ossicles (arm bones). Here, we estimated the maximum life span, age distribution, and growth rate of the common, large Arctic endemic brittle star, <jats:italic>Ophiopleura borealis</jats:italic>, from the northern Barents Sea. We counted growth bands in trawl-caught specimens using scanning electron microscope images of the innermost arm ossicles of 80 specimens spanning the known size range. These counts were corrected for overgrowth of the earliest growth bands, and growth parameters were estimated using common growth models. The age bands appeared as alternating layers of dense and less dense lines in the stereom of the ossicle fossae. The maximum corrected age band count was 39, which we infer as reflecting the age in years. This estimate is higher than for most other studied brittle stars, including polar species. Most individuals in the sampled population spanned estimated ages from 25-32 years. The growth constant <jats:italic>k</jats:italic> estimates of 0.09 from the Single logistic growth model and 0.01 from the specialized van Bertalanffy model indicate slow growth.

The analysis was performed on 270 wild specimens of both sexes at different sizes (45-200 mm of mantle length; 6.98-443 g of total weight) and maturity stages (immature, maturing and mature) caught from July to September by trawl net. Significant differences in growth and length-weight relationship were observed between sexes, due to females reach a larger size than males. All the three structures had dimensions positively correlated with the size of the animals and showed clearly readable growth increments. Low values of IAPE, CV and PA confirmed the accuracy and good reproducibility of age readings. Eye lenses showed a very high number of growth increments (106-640), and a daily deposition was excluded. In contrast, beaks and statoliths showed NI values (70-316 and 73-310, respectively) always consistent with the size and maturity of the specimens, then a daily deposition has been suggested and their value compared.

The absolute growth rates confirm that females grow faster than males. Both sexes showed a higher initial growth rate, which gradually decreases, with the highest values at the age of 101-151 days, before reaching sexual maturity.

Rivers, submarine groundwater discharges (SGD), sediment suspension events, and upwelling, are amongst the more important. However, it is not just the concentration, but also the composition of nutrient supply that determines the type of phytoplankton community that develops, subsequently influencing the entire food web. It is therefore necessary to better understand the link between physical processes, nutrient composition and phytoplankton response in coastal oceans. This study investigates the effects of upwelling and submarine groundwater discharges on the phytoplankton community of a wide and shallow continental shelf.MethodsResults are achieved by using numerical modeling of dispersion events, as well as field data obtained from three oceanographic cruises, each representing a different hydrographic scenario (“No upwelling”, “Minor upwelling and SGD” and “Major upwelling and minor SGD”).ResultsThe upwelled water mass (SUW – Subtropical Underwater) was primarily found at the eastern end of the shelf (Cabo Catoche), where it rises and is transported westward by advection. The oceanographic stations influenced by the upwelled water showed an increase in diatom species population, known to thrive in environments with abundant inorganic nutrients. In contrast, submarine groundwater discharges were recorded nearshore on the western half of the shelf, mainly related to karst features of hydrogeological importance (a sinkhole ring associated with the Chicxulub crater). The stations with SGD influence had higher presence of nutrients such as NH4, suggesting recycling processes. This can modify either the phytoplankton community advected from Cabo Catoche, or promote local growth, leading to a dominance of dinoflagellates and unknown flagellates.DiscussionThis result implies a food web, similar to that of the mixoplankton-dominated microbial loop, which would be fed by organic matter of continental origin.","PeriodicalId":12479,"journal":{"name":"Frontiers in Marine Science","volume":"90 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143757763","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}
