The last 50 years have seen a revolution in our understanding of ocean processes. I consider the major developments in three eras: (1) ending roughly 1970, observations were generally interpreted in terms of steady circulation models of large-scale, with variability regarded as "noise"; (2) following 1970, emphasis was on mesoscale variability (which was found to contain 99 percent of th...
Many of the individuals who participated in the exciting discoveries in biological oceanography, chemical oceanography, physical oceanography, and marine geology and geophysics describe in the book how the discoveries were made possible by combinations of insightful individuals, new technology, and in some cases, serendipity.
One is physical oceanography, the study of the relationships between the seafloor, the coastline, and the atmosphere. The other is chemical oceanography, the study of the chemical composition of seawater and how it is affected by weather, human activities, and other factors. About 70 percent of Earth’s surface is covered by water.
The expertise of the physical oceanography community should make possible substantial advances in the understanding of all these shallow systems. Because of the major roles played by turbulence and complex topography, these systems pose impressive and fascinating challenges to physical oceanography.
NSF's mission is to advance the progress of science, a mission accomplished by funding proposals for research and education made by scientists, engineers, and educators from across the country.
The major disciplines of oceanography are geological oceanography, physical oceanography and chemical oceanography. Oceanographers and others involved in these disciplines often work together to unravel the mysteries and unknowns of ocean science. In reading about each of these sub-fields, keep in mind that some of the most important oceanographic discoveries have been made as a result of an ...
Most of the major discoveries in oceanography have occurred only within the last 50 years. We have found that while rocks and sediments on land are usually wiped away by weather and erosion, rocks and sediments on the seafloor are a well-preserved archive of information that allows us to unravel Earth’s geological processes and history.
Momentous discoveries in oceanography Sara Mynott September 20, 2013 Geoscientific Methods , Ocean Sciences 1 Comment Earlier this month, one of our network bloggers, Matt Herod, put out a call for posts on momentous discoveries in geology as part of a well-known geoscience blog carnival, The Accretionary Wedge .
Physical oceanography is a sub-discipline of oceanography that involves the study of waves, tides, and currents; the ocean-atmosphere relationship that influences weather and climate; and the transmission of light and sound in the oceans.The scales of these processes range through spatial scales from centimeters to global and time scales from seconds to centuries.
The Physical Oceanography Program supports research on a wide range of topics associated with the structure and movement of the ocean, with the way in which it transports various quantities, with the way the ocean's physical structure interacts with the biological and chemical processes within it, and with interactions between the ocean and the ...
