The Yellow Sea is a strongly tidally-driven and highly stratified shallow sea due to the presence of Cold Water Masses. Observations show that near-inertial event sustains for 10 days with peak velocity 0.15m/s, which accounts 30% total during passage cyclone. Near-inertial dominated by first baroclinic mode one zero-crossing at depth maximum stratification two peaks in mixed layer below thermo...

The Humboldt coastal upwelling system in the eastern South Pacific ocean is one of the most productive marine ecosystems in the world. A weakening of the upwelling activity could lead to severe ecological impacts. As coastal upwelling in eastern boundary systems is mainly driven by wind stress, most studies so far have analysed wind patterns change through the 20th and 21st Centuries in order t...

Using the Monte Carlo method of statistical physics, we compute the equilibrium statistical mechanics of the shallow water equations, considered as a reduced-gravity model of the ocean’s upper layer in a square ocean that spans the equator. The ensemble-averaged flow comprises a westward drift at low latitudes, associated with the poleward deepening of the main thermocline, and a more intense c...

Protists represent the majority of eukaryotic diversity in oceans. They have different functions marine food web, playing essential roles biogeochemical cycles. While available data is rich horizontal and temporal coverage, little known on their vertical structuring, particularly below photic zone. The present study applies V4 18S rDNA metabarcoding to samples collected over three years conjunc...

[1] Throughout the Cenozoic the Earth experienced global cooling that led to the appearance of continental glaciers in high northern latitudes around 3 Ma ago. At approximately the same time, cold surface waters first appeared in regions that today have intense oceanic upwelling: the eastern equatorial Pacific and the coastal zones of southwestern Africa and California. There was furthermore a ...

A recently developed parametric model by P. C. Chu et al. is used in this paper for determining subsurface thermal structure from satellite sea surface temperature observations. Based on a layered structure of temperature fields (mixed layer, thermocline, and lower layers), the parametric model transforms a vertical profile into several parameters: sea surface temperature (SST), mixed layer dep...

The common thresher shark (Alopias vulpinus) is a secondary target species of the California drift gillnet fishery (CA-DGN) and supports a growing recreational fishery in California waters. This study used archival tags to examine the movement patterns and habitat preferences of common threshers of the size range captured in the CA-DGN (>120 cm fork length). Depth and temperature-logging archiv...

Today, a 34m global equivalent water layer (GEL) lies in the Martian polar-layered deposits and shallow ground ice. During the Amazonian, 3m was outgassed, and 31m was lost to space and to the surface, leaving 62m at the end of Hesperian. During the Hesperian, volcanic outgassing added 5m, 7m was lost, and 40m GEL of groundwater was added to form outflow channels, leaving 24m carryover of surfa...
