East Australian Current, surface oceanic current, a section of the counterclockwise flow in the Tasman Sea, southwestern Pacific Ocean. It is formed by water masses from the Coral Sea—equatorial water driven by monsoonal winds from January to March and eastward subtropical flow from April to Decem...
Atlantic Ocean, body of salt water covering approximately one-fifth of Earth’s surface and separating the continents of Europe and Africa to the east from those of North and South America to the west. The ocean’s name, derived from Greek mythology, means the “Sea of Atlas.” It is sec...
Upper-ocean fronts and eddies are dynamic features that importantly contribute to mesoscale variability, coupled physical-biochemical processes, and rapid changes in air-sea interaction. Such features are usually manifested by the sea surface temperature pattern and chlorophyll-aconcentration, in thermal in...
South of about 32°S, eddying extends even farther into the equatorward flow of cool, high-salinity water of the subtropical gyre, sometimes referred to as the West Australian Current. The temperature gradient between Leeuwin flow and the offshore gyral water becomes stronger progressively ...
To analyze ocean states, we used vertical profiles of water temperature and density from the Global Ocean Reanalysis and Simulation (see GLORYS in Methods)46. The daily GLORYS12V1 was used with a standard regular grid with 1/12° (approximately 8 km) interval and 50 standard levels. The...
Distribution map (presence data) of O. asperrima, O. bisotunensis, O. kotschyi, O. platyphylla, and O. straussii in Iran is shown in Figure 2. The point inputs to the models developed in this study were collected from their habitats in the west and southwest of Iran such as Fars,...
Net primary production (NPP) is the foundation of the oceans’ ecosystems and the fisheries they support. In the Arctic Ocean, NPP is controlled by a complex interplay of light and nutrients supplied by upwelling as well as lateral inflows from adjacent
题目Before 1965 many scientists pictured the circulation of the ocean"s water mass as consisting of large slow-moving currents, such as the Gulf Stream. That view, based on 100 years of observations made around the globe, produced only a rough approximation of the true circulation....
(Note that measurements closer than 100 km to the coast may have a substantial effect of the orography and the coastline on the wind19,39.) The resulting global map is slightly smoothed (over 50 km) to diminish sampling noise due to the relatively short analysis period (9 years). The...
Sea surface temperature ranged from 28.7°C to 31°C in the August 2018-February 2019 period and there was no bleaching seen then. However, when the temperatures rose to between 32°C and 36°C between March 2019 and May 2019, researchers observed a pattern of bleaching in corals, which ...
