    A peculiar lens-shaped structure observed in the South China Sea

    Abstract: Lens-shaped structures within thermocline potentially play a significant role in subsurface transport of mass, heat, and salt in the global ocean. Whilst such structures have been documented in many oceanic regions, none has been observed in the China Seas. This study reports on observations of a lens-shaped structure within thermocline in the southwestern South China Sea in September 2007. This structure had a maximum thickness of approximately 60 m and a horizontal extent exceeding 220 km. This lens was peculiar in that its size is larger than most similar structures documented in the literature. The lens core was characterized by well-mixed water with higher temperature (~28.8 °C), lower salinity (~33.3) and lower potential vorticity (PV) compared to the surrounding waters. Based on an ocean reanalysis, possible generation mechanism of the lens is explored by examining the evolution of surface and subsurface thermohaline properties, and an analysis of vertical PV flux. The lens was likely generated by a mixture of the local mixed-layer water and the water from the coastal jet separation site.

    Temporal variability of the Subarctic Front near the Charlie‐Gibbs Fracture Zone
    American Geophysical Union (AGU) ; 1996

    Abstract: We document temporal variability of the northernmost branch of the North Atlantic Current, known as the North Subarctic Front (NSAF), for the period 1976–1985. The front's location and temperature‐salinity ( T‐S ) parameters were determined from 120 repeat transects along three standard sections occupied by Russian ships: (1) ocean weather station (OWS) “C” (52.75°N, 35.5°W) to St. John's, Newfoundland; (2) along 35°W, from 52°N to 36.5°N; and (3) OWS C to Cape St. Vincent, Portugal. The NSAF exhibits significant interannual variability of its location, shifting 200 km to 300 km in a few months. Along the OWS C‐St. John's section, the front reached its southernmost location in 1976–1977, then experienced two 250‐to‐300‐km northward shifts, in 1978–1979 and 1980–1981; all of the three shifts peaked in wintertime. These events nearly coincide with events of the opposite sign along the OWS C‐Cape St. Vincent section (the northernmost location in 1976–1977 and two 200‐km southward shifts, in 1978–1979 and 1980–1981). The NSAF's behavior is thus coherent near the Charlie‐Gibbs Fracture Zone at the 500‐km scale. Frontal time series (associated with the moving front) of T and S at the 200‐m level for the cold side of the NSAF reveal two events: an S 200 minimum in the winter of 1976–1977, which might be a manifestation of the “Great Salinity Anomaly” of the 1970s, and a sharp drop of S 200 in early 1984, which might signal the arrival of another large salinity anomaly, the “Great Salinity Anomaly” of the 1980s.

    The China Coastal Front from Himawari-8 AHI SST Data—Part 1: East China Sea
    MDPI AG ; 2023
    In:  Remote Sensing Vol. 15, No. 8 ( 2023-04-17), p. 2123-

    In: Remote Sensing, MDPI AG, Vol. 15, No. 8 ( 2023-04-17), p. 2123-
    Abstract: High-resolution (2 km) high-frequency (hourly) SST data from 2015–2020 provided by the Advanced Himawari Imager (AHI) onboard the Japanese Himawari-8 geostationary satellite positioned over 140.7°E were used to study spatial and temporal variability of the China Coastal Front (CCF) in the East China Sea. This dataset was processed with the Belkin and O’Reilly algorithm to generate long-term mean monthly maps of the SST gradient magnitude (GM) and frontal frequency (FF). The horizontal structure of the SST field in the vicinity of the CCF was also investigated from the cross-frontal distributions of SST along eight parallels between 31°N and 24°N. The monthly mean distributions of SST along these 8 parallels were used to determine inshore and offshore boundaries of the CCF and to calculate the CCF strength defined as the total cross-frontal step (range) dSST calculated as the difference between offshore and inshore SST. The CCF emerges in November, fully develops in December, and peaks in strength in January–February. The front’s fragmentation and shrinking/weakening begins in February and March, respectively. In winter (December–February), the front’s strength dSST exceeds 5 °C offshore the Zhejiang-Fujian coast and could be as high as 7.5 °C when nearshore waters cool down to 7 °C. In winter, the front’s strength decreases downstream between 31°N and 24°N. The CCF changes its physical nature as the seasons progress. In winter, the CCF is a water mass front between the cold and fresh water coming from the north and the warm and salty water coming from the south. In summer, the CCF becomes a coastal upwelling front maintained largely by southerly winds. In winter, the CCF’s cross-frontal structure in the SST field is ramp-shaped, with SST increasing monotonously in the offshore direction. In summer, the CCF’s cross-frontal structure in the SST field is V-shaped or U-shaped, featuring a minimum SST formed by cold upwelled water at some distance from the shore. Thus, the summer SST structure effectively consists of two parallel fronts, an inshore one and an offshore one, with a minimum SST in between. Across the inshore/offshore front, the SST decreases/increases in the offshore direction.

    Remote Sensing of the Subtropical Front in the Southeast Pacific and the Ecology of Chilean Jack Mackerel Trachurus murphyi

    Abstract: The Subtropical Front (STF) plays a key role in the ecology of Chilean jack mackerel Trachurus murphyi. Nonetheless, there are few remote sensing studies of the STF in the open Southeast Pacific, and almost all of them have been conducted by satellite oceanographers in Russia and Ukraine to support respective large-scale fisheries of jack mackerel in this region. We reviewed these studies that documented long-term seasonal and interannual variability of the STF from sea surface temperature (SST) and sea surface height (SSH) data. We also mapped the STF from satellite sea surface salinity (SSS) data of the SMOS mission (2012–2019). The Subtropical Front consists of two fronts–North and South STF about 500 km apart–that border the Subtropical Frontal Zone (STFZ) in-between. The STF is density-compensated, with spatially divergent manifestations in temperature and salinity. In the temperature field, the STF extends in the WNW to ESE direction in the Southeast Pacific. In the salinity field, the STFZ appears as a broad frontal zone, extending zonally across the entire South Pacific. Three major types of satellite data-SST, SSH, and SSS-can be used to locate the STF. The SSH data is most advantageous with regard to the jack mackerel fisheries, owing to the all-weather capability of satellite altimetry and the radical improvement of the spatial resolution of SSH data in the near future. Despite the dearth of dedicated in situ studies of the South Pacific STFZ, there is a broad consensus regarding the STFZ being the principal spawning and nursing ground of T. murphyi and a migration corridor between Chile and New Zealand. Major data/knowledge gaps are identified, and key next steps are proposed to mitigate the data/knowledge gaps and inform fisheries management.
