A drifter (not to be confused with a float) is an oceanographic device floating on the surface to investigate ocean currents by tracking location. They can also measure other parameters like sea surface temperature, salinity, barometric pressure, and wave height. [1] Modern drifters are typically tracked by satellite, [2] often GPS.
An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, ...
Seattle oceanographers Curtis Ebbesmeyer and James Ingraham, who were working on an ocean surface current model, began to track their progress. The mass release of 28,800 objects into the ocean at one time offered significant advantages over the standard method of releasing 500–1000 drift bottles. The recovery rate of objects from the Pacific ...
A crucial system of ocean currents may already be on course to collapse with devastating implications for sea level rise global weather — leading temperatures to plunge dramatically in some ...
New research warns of a possible collapse in Atlantic Ocean currents due to climate change. That could fundamentally alter global weather patterns.
Surface temperatures in the western North Atlantic: Most of the North American landmass is black and dark blue (cold), while the Gulf Stream is red (warm). Source: NASA The Gulf Stream is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States, then veers east near 36°N latitude ...
Ocean tracers are used to deduce small scale flow patterns, large-scale ocean circulation, water mass formation and changes, "dating" of water masses, and carbon dioxide storage and uptake. [2] [3] Temperature, salinity, density, and other conservative tracers are often used to track currents, circulation and water mass mixing. [4]
Using the bottom track feature, the track of the boat as well as the cross sectional area is estimated after adjustment for left and right bank areas. The discharge can then be calculated as the dot product between the vector track and the current velocity. The method is in use by hydrographic survey organisations across the world and forms an ...
