  • Ocean currents - National Oceanic and Atmospheric Administration
    Ocean water is on the move, affecting your climate, your local ecosystem, and the seafood that you eat Ocean currents, abiotic features of the environment, are continuous and directed movements of ocean water These currents are on the ocean’s surface and in its depths, flowing both locally and globally
  • Ocean Circulations - National Oceanic and Atmospheric Administration
    Keeping Current While ocean currents are shallow-level circulations, there is global circulation which extends to the depths of the sea called the Great Ocean Conveyor Also called the thermohaline circulation, it is driven by differences in the density of the sea water which is controlled by temperature (thermal) and salinity (haline)
  • What are Ocean Currents? | Every Full Moon | Ocean Today
    Surface ocean currents on the open ocean are fantastically complicated and beautiful, driven by a complex global wind system But there's one more ocean current force that you may have never heard of It's called thermohaline circulation Thermo means 'heat,' and 'haline' refers to salinity
  • Currents: NOAAs National Ocean Service Education
    Currents driven by thermohaline circulation occur at both deep and shallow ocean levels and move much slower than tidal or surface currents The Currents Tutorial is an overview of the types of currents, what causes them, how they are measured, and how they affect people's lives
  • JetStream Max: Major Ocean Currents - National Oceanic and Atmospheric . . .
    This image will help identify the top 25 of the world's wind driven ocean currents To view each current individually, uncheck the "All Currents" box, then check the box for each of the individual currents Currents indicated by the red color are considered "warm" currents as they transport warm water (and heat) toward the poles The blue colored currents indicate they transport cold water
  • Ocean motion: Wind-driven currents - National Oceanic and Atmospheric . . .
    Ocean motion: Wind-driven currents Model the flow of ocean surface currents by blowing air across a tub of rheoscopic fluid and water, with clay structures simulating coastlines, islands, and seafloor features Share: Background Winds, water density, and tides all drive ocean currents
  • Ocean Surface Current Analyses Real-time (OSCAR) Surface Currents . . .
    Ocean Surface Current Analyses Real-time (OSCAR) is a global surface current database and NASA funded research project OSCAR ocean mixed layer velocities are calculated from satellite-sensed sea surface height gradients, ocean vector winds, and sea surface temperature gradients using a simplified physical model for geostrophy, Ekman, and
  • Ocean pollution and marine debris - National Oceanic and Atmospheric . . .
    These patches are formed by large, rotating ocean currents called gyres that pull debris into one location, often to the gyre’s center There are five gyres in the ocean: one in the Indian Ocean, two in the Atlantic Ocean, and two in the Pacific Ocean Garbage patches of varying sizes are located in each gyre
  • Learning Lesson: How it is Currently Done - National Oceanic and . . .
    Unlike the slow drift of ocean currents, rip currents are powerful, local, channeled currents of water flowing away from shore They typically extend from the shoreline, through the surf zone, and past the line of breaking waves
  • Ocean Circulation - NASA Earthdata
    Ocean currents are continuous water movements driven by wind, temperature and salinity variations, tides, Earth's rotation, and waves These forces interact in complex ways, further shaped by seafloor topography, coastlines, and mixing between current systems
