Three‐dimensional structure of the summertime circulation in the Yellow Sea from a wave‐tide‐circulation coupled model

Abstract: [1] The three-dimensional structure of the summertime circulation of the Yellow Sea (hereafter YS) is studied by using a prognostic wave-tide-circulation coupled model based on the Princeton Ocean Model (POM) and a surface wave model. The simulated tidal harmonic constants and temperature structure agree with the observations well. The patterns of the simulated salinity generally agree also with the observations. The simulated results show that the horizontal circulation has a three-layer structure: in the surface layer (0–4 m), the prevailing current direction is northeastward; in the upper layer (4–40 m) it is dominated by a basin scale anticlockwise (cyclonic) gyre; in the bottom layer (below 40 m) the water diverges from the center area and there exists a weak southward current along the YS trough. The stream function of the YS shows that the net circulation of the YS is an anticlockwise (cyclonic) one, and the net transport is about 0.1 Sv. Diagnostic analysis of the momentum balance and sensitivity show that the cyclonic circulation in the upper layers is mainly a quasi-geostrophic flow along tidal-induced temperature front, and it is also strengthened by the tide residual currents. The tidal residual current and the compensation for northward surface layer wind transport contribute to the formation of southward flow in the bottom layer. The vertical circulations vary along different sections. A circulation cell is found in the frontal area near the Korean coast, and an upwelling is found along the slope.

Food protein-derived chelating peptides: Biofunctional ingredients for dietary mineral bioavailability enhancement

Abstract: Minerals such as calcium, zinc, iron and copper are important elements for human health. Deficiencies of dietary minerals can lead to numerous diseases. Mineral chelating peptides have shown potential application in the management of mineral deficiencies. An increasing number of chelating peptides with the ability to facilitate and enhance the bioavailability of minerals are being discovered and identified. This review outlines the current food protein sources, analytical methods and the purification schemes of mineral chelating peptides, and discusses their structure–activity relationship and the bioavailability. The potential of mineral chelating peptides as functional food ingredients is also described.
