Two categories of ice have to be considered in context of oceanic freshwater fluxes: sea ice and (recently) grounded ice like ice shelfs and icebergs. Sea ice is considered as part of the oceanic water budget, therefore, its melting or freezing states not an input or output of water in general.
Broken pieces of Arctic sea ice with a snow cover. Sea ice arises as seawater freezes. Because ice is less dense than water, it floats on the ocean's surface (as does fresh water ice). Sea ice covers about 7% of the Earth's surface and about 12% of the world's oceans.
Water resources, natural risks (floods, climate change, hurricane forecasting, etc.), biodiversity, health (preventing the propagation of water-borne diseases), the agricultural sector, energy (including the management of electricity production and offshore gas and oil rigs), territorial development; all these areas and more stand to benefit ...
Deep-sea vents were discovered in 1977 by Jack Corliss and Robert Ballard in the submersible DSV Alvin. [28] In the 1950s, Auguste Piccard invented the bathyscaphe and used the bathyscaphe Trieste to investigate the ocean's depths. The United States nuclear submarine Nautilus made the first journey under the ice to the North Pole in 1958. In ...
The ocean is home to a variety of marine organisms known as extremophiles – organisms that thrive in extreme conditions of temperature, pressure, and light availability. Extremophiles inhabit many unique habitats in the ocean, such as hydrothermal vents, black smokers, cold seeps, hypersaline regions, and sea ice brine pockets. Some ...
Arctic sea ice extent was lower on Dec. 21, 2024, compared to that date in 2016 − contrary to the claim made in the post. But even if sea ice had been higher in 2024 at both poles, that wouldn't ...
The following outline is provided as an overview of and introduction to Oceanography.. Thermohaline circulation. 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.
Marla Gibbs, the last living original core cast member from "The Jeffersons," made a surprise cameo this week during ABC's "Live in Front of a Studio Audience: Norman Lear's 'All in the Family ...
