Deep Connections: Differences Between Deep Ocean and Surface Currents
The flow of ocean currents follows predictable patterns governed by a variety of physical factors. For surface currents, which include water flow horizontally in the upper four hundred meters of the ocean, wind is the primary driving force. For deep...
Deep Connections: Deep Ocean Circulation and Global Climate
Some scientists are concerned that just as thermohaline circulation has changed significantly over time, it could change again and possibly cause abrupt climate change in both the United States and Europe.
Deep Connections: Tracers
A tracer is a property or substance that can be used to track the movement of individual water masses. While the utility of specific tracers varies according to the locale and circumstance, tracers as a group provide a rich source of information ab...
Deep Connections: Ocean Observation Systems
While tracers have proven immensely valuable as tools with which to monitor and analyze ocean circulation, the sheer size of the world ocean presents an enormous data-gathering challenge. Many oceanographers believe the solution lies in profiling sy...
Deep Connections: Water Masses
Water masses are layers of water distinguished by a particular temperature and salinity. Understanding how water masses form and move around is critical in understanding global climate.
Deep Connections: Thermohaline Circulation
The movement of water due to differences in density is called thermohaline circulation. This process is responsible for not only the vertical movement of ocean water, but for the circulation of the global ocean as a whole.
