In order to study the impact of artificial reef construction on marine carbon sinks, a one-year monitoring and analysis were carried out in Sanheng areas Shengsi Island. The main parameters observed sea surface temperature, salinity, pH, total alkalinity (TA), dissolved inorganic (DIC). partial pressure CO2 (pCO2w) water flux (FCO2) across sea–air interface calculated analyzed. results showed that annual range pCO2w was 34.48~501.53 μatm, decreases following order: winter, spring, autumn, summer. FCO2 significantly negatively correlated with temperature positively salinity TA. four seasons survey area ranged from −108.79 41.74 mmol m−2 d−1. both control displayed positive values, indicating source CO2, while other three seasons, values negative, an overall sink. Additionally, exhibited stronger sink than area. indicated reefs has certain effect, no significant difference effectiveness between different models.

Abstract Bivalve farming was usually considered as a CO 2 source through respiration and calcification, but recent studies suggest its potential sink, prompting exploration of inclusion in carbon markets. Here we reviewed the scientific basis behind this idea found that it is not supported by observational experimental studies. This indeed arises from budget models are based on theoretical misconceptions regarding seawater carbonate chemistry. The main misunderstanding consists assuming trapped shell originates atmospheric when mostly comes (bi)carbonate ions. While these ions originate erosion minerals over geological time scales, their incorporation into shells does prompt short‐term compensation. opposite occurs—calcification releases limits or even prevents uptake . Some authors considering bivalve farm ecosystem could change perspective source/sink issue there no evidence for now. Most ecosystem‐based rely several unverified assumptions estimates. Although challenging, field measurements must be conducted monitoring, reporting, verifying before qualifying credits. To achieve consensus, need reinforcing measurement‐based fluxes shellfish ecosystems, integrating balance with science, fostering interdisciplinary collaboration. provides numerous environmental benefits vital sustainable aquaculture, currently contributes to capture.

Purpose To achieve sustainable development in shipping, accurately identifying the impact of artificial intelligence on shipping carbon emissions and predicting these is utmost importance. Design/methodology/approach A multivariable discrete grey prediction model (WFTDGM) based weakening buffering operator established. Furthermore, optimal nonlinear parameters are determined by Grey Wolf optimization algorithm to improve performance, enhancing model’s predictive performance. Subsequently, global data employed validate effectiveness our new chosen algorithm. Findings demonstrate applicability robustness marine emissions, used forecast emissions. Additionally, a comparative analysis conducted with five other models. The empirical findings indicate that WFTDGM (1, N) outperforms models overall efficacy, MAPE for both training test sets being less than 4%, specifically at 0.299% 3.489% respectively. out-of-sample forecasting results suggest an upward trajectory over subsequent four years. Currently, application mitigating shipping-related has not achieved desired inhibitory impact. Practical implications This research only deepens understanding mechanisms through which influences but also provides scientific basis developing effective emission reduction strategies industry, thereby contributing significantly green efforts. Originality/value multi-variable developed this paper effectively mitigates abnormal fluctuations time series, serving as valuable reference promoting low-carbon transitions economic development. paper, even higher performance can be constructed integrating it algorithms.

The ocean is the largest carbon sink on Earth and an important pathway to China achieving neutrality. From a consumption perspective, studying capacity of marine in each China’s provinces its inter-regional transfer great significance harnessing increase driven by final demand. This article first calculates production-side coastal provinces. Then, based 2007, 2012, 2015, 2017 Chinese input-output tables, province’s consumption-side calculated. further examines influencing factors key paths for growth through Structural Decomposition Analysis (SDA) Path (SPA) methods. results show that total continues rise, with significant regional disparities, demonstrating trend higher than inland Among nine provinces, Hainan Guangdong are net input state regarding transfer, while other seven output state. SDA indicate intensity effect demand inhibiting promoting growth, respectively, influence technical weak variable. SPA analysis reveals outputs primarily transferred food tobacco sector, agricultural forestry products services wood processing furniture industry. mostly occur within province, relatively small proportion interprovincial paths. Based research findings, this suggests steadily increasing product consumption, actively expanding value chain shellfish seaweed industries, continuously strengthening coordination between land domestic circulation sinks.

The East China Sea frequently experiences red tide outbreaks, significantly impacting marine carbon sink dynamics and ecosystem health. This study examines the temporal spatial variations of events in 2012 -2021, utilizing MODIS remote sensing imagery with a focus on summer outbreaks. Using Two-Step algorithm, we assess surface particle organic (POC) levels tide-affected areas, providing crucial insights into potential distribution patterns phytoplankton. Key findings include: (1) largest outbreak area occurred 2015, substantial fluctuations observed along Zhejiang coast compared to more stable Yangtze River estuary, especially 2018 2020. (2) Surface POC concentrations reached their peak at 404.37 g m−3 estuary 2021 359.83 2017, lowest values recorded 2013 2015. (3) Spatially, severe algal bloom higher are coastal areas Zhejiang-Fujian, but different causes. These highlight importance regional role achieving sustainable development goals.
