“…For example, an anomalous shoreward KC interacts with bottom topography and drives intense nutrient-rich upwelling on continental shelves (Yang et al 2011, Cui et al 2021, which fertilizes coastal areas such as the Zhoushan fishing ground (Lin et al 2019). Additionally, an anomalous onshore movement of the KC could result in significant warming of the Pacific Asian marginal seas, especially the continental shelf of the ECS, contributing to the formation of intense marine heatwaves (Lee et al 2023, Wang et al 2023. For instance, the rapid warming of the East Asian marginal seas is attributed to the Kuroshio intrusion (Wang and Wu 2022).…”

The Kuroshio Current (KC) in the East China Sea is one of the most prominent components of the ocean circulation system in the North Pacific. The onshore intensification of the KC is found to drive nutrient-rich upwelling in the shelf regions, induce anomalous warming that leads to coastal marine heatwaves, and reduce the ability of the oceans to absorb anthropogenic carbon dioxide. Based on altimeter and in situ observations, we find an onshore acceleration and offshore deceleration of the KC over the past three decades. This intensification is characterized by a spatial mean onshore acceleration (offshore deceleration) of 0.39 (-0.63) cm s-1 per decade. This phenomenon can be attributed to changes in wind stress curl and oceanic stratification over the subtropical North Pacific. The weakened wind stress curl decreases the vertical extent of the KC by reducing its transport and contributes to the offshore deceleration, whereas the enhanced stratification drives the uplift of the KC and contributes to the onshore acceleration. Our findings underscore the importance of establishing and maintaining a long-term monitoring network for the zonal variations of the KC in the future to obtain a comprehensive understanding of the associated impacts.

“…This region has experienced exceptionally intense MHWs, including record‐breaking occurrences in 2016–2018 and 2022, with SST anomalies exceeding 4–5°C (Gao et al., 2020; Lee et al., 2023). The NECS‐SYS region also frequently encounters harmful algae blooms associated with warm SST or MHWs (Wang et al., 2023; Zhou et al., 2022). These blooms significantly lower oxygen levels, expanding coastal hypoxic zones, which endanger coastal and marine ecosystems and substantially affect human health (Berdalet et al., 2015; Cai et al., 2016).…”

During the summer of 2016, the northern East China Sea and the southern Yellow Sea (NECS‐SYS) experienced one of the most severe and devastating marine heatwaves (MHWs) on record, with a temperature anomaly exceeding 4°C. This shallow semi‐enclosed continental shelf region is widely recognized as a significant hotspot for MHWs with associated incidences of harmful algae blooms. Previous studies have highlighted the importance of mixed layer shoaling as a crucial factor in the genesis of MHWs in the global ocean. The current study employed the Hybrid Coordinate Ocean Model reanalysis data set during 1994–2015 to delve into the mechanisms driving mixed layer shoaling during NECS‐SYS MHW genesis. Our findings reveal the significant role of the northward propagating boreal summer intraseasonal oscillation in promoting MHW genesis and intensification. Specifically, boreal summer intraseasonal oscillation phases 5, 6, and 7 contribute to the favorable conditions that facilitate MHW formation by inducing mixed layer shoaling and increasing solar influx, with mixed layer shoaling playing a more dominant role. The current study provides insights into the relative influences of wind, salinity, and temperature on mixed layer shoaling. We observe that wind plays the most significant role in mixed layer shoaling, followed by temperature and salinity. The boreal summer intraseasonal oscillation induced wind relaxation, increased shortwave radiation, and freshwater influx lead sea surface temperature by 7, 5, and 4 days, respectively. Importantly, mixed layer shoaling leads SST anomalies by 1–2 days. Therefore, the current study also suggests an intraseasonal predictability source for NECS‐SYS MHWs.

“…According to Miah et al (2023) [9], SSS is an additional important oceanographic component that has a major impact on fish physiology, spawning, reproduction, and distribution. Plankton abundance and fish species that depend on these resources are impacted by MLD's effects on water column temperature and nutrient distribution [10]. Fisheries are impacted by a wide range of other factors, though [11].…”

The depletion of the grey mullet population in the Taiwan Strait has generated interest in conservation initiatives and to enhance the effectiveness of restoration initiatives, it is essential to comprehend the specific habitat preferences of the species in question, particularly in relation to environmental changes. In this study, habitat suitability modelling was used to investigate the distribution patterns of grey mullet. Sea surface height (SSH) was the most significant predictor of the grey mullet standardized catch per unit effort (S.CPUE). Furthermore, sea surface temperature (SST) was the second most important oceanographic parameter, followed by mixed-layer depth (MLD). The grey mullet S.CPUE peaked in regions with the summed SST, Chla, salinity, SSH, MLD and current values being 20 °C, 0.9 mg/m3, 34.5 psu, 0.45 m, 18–38 m, and 0.25 m2/s2, respectively. From late October, HSI levels in the northern Taiwan ocean increased, with a consistent upward trend. The distribution expanded in November and December, focusing on the northern and mid-ocean regions west of Taiwan. HSI levels peak in January and February, especially in Taiwan’s coastal region. High HSI distribution shifts away from coastlines and diminishes in April. The findings of this study will contribute to the understanding of this specific species and the approach used in this study may be applicable to other fisheries stocks also.
