Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean' and γραφή (graphḗ) 'writing'), also known as oceanology, sea science, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology.
Particular attention is paid to the atmosphere/ocean interface and the sediment/ocean interface, as well as to elements and compounds which can cycle and cause radiative forcing. Research ranges from the atmosphere over the ocean, through the ocean surface layer into the water column, and then down to the marine sediments and the oceanic crust.
Sidescan sonar was developed in the 1950s to 1970s and could be used to create an image of the bottom, but the technology lacked the capacity for direct depth measurement across the width of the scan. In 1957, Marie Tharp, working with Bruce Charles Heezen, created the first three-dimensional physiographic map of the world's ocean basins. Tharp ...
A part of the Pacific Ocean earmarked for deep-sea mining is home to a surprising variety of life, images from a recent ... the creature is a type of sea pig within the scientific family called ...
Remote sensing as we know it today started with the first earth orbiting satellite Landsat 1 in 1973. [10] Landsat 1 delivered the first multi-spectral images of features on land and coastal zones all over the world and already showed effectiveness in oceanography, [11] although not specifically designed for it.
On board, scientists can use the four labs to analyze samples, sequence DNA, and study specimens. Meanwhile, ROVs explore the deep; sonar maps the seafloor; and a sampling tool measures the water ...
Scientists used satellite imagery and data to analyze vegetation levels on the Antarctic Peninsula, a long mountain chain that points north to the tip of South America, and which has been warming ...
