NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather ...
The largest terrestrial seas, in decreasing order of area, are: Philippine Sea – 5.695 million km 2 (2.199 million sq mi) Coral Sea – 4.791 million km 2 (1.850 million sq mi) American Mediterranean Sea – 4.200 million km 2 (1.622 million sq mi) Arabian Sea – 3.862 million km 2 (1.491 million sq mi)
The Sargasso Sea (/ sɑːrˈɡæsoʊ /) is a region of the Atlantic Ocean bounded by four currents forming an ocean gyre. [1] Unlike all other regions called seas, it has no land boundaries. [2][3][4] It is distinguished from other parts of the Atlantic Ocean by its characteristic brown Sargassum seaweed and often calm blue water.
Google Earth is a web and computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering ...
Titan began its dive at 09:17 local time and support staff aboard the mother ship asked about the submersible's depth and weight, as well as whether it could still see the ship on its onboard display.
Satellite images by NASA in August 2014 revealed that for the first time in modern history the eastern basin of the Aral Sea had completely dried up. [7] [8] The eastern basin is now called the Aralkum Desert. In an effort in Kazakhstan to save and replenish the North Aral Sea, the Dike Kokaral dam was completed in 2005.
A surveyor uses a GNSS receiver with an RTK solution to accurately locate a parking stripe for a topographic survey. Real-time kinematic positioning (RTK) is the application of surveying to correct for common errors in current satellite navigation (GNSS) systems. [1] It uses measurements of the phase of the signal's carrier wave in addition to ...
Milky sea effect off the coast of Somalia in the Indian Ocean. Milky seas (Somali: Kaluunka iftiima; English: Milky seas), also called mareel, is a luminous phenomenon in the ocean in which large areas of seawater (up to 6,000 sq mi or 16,000 km 2) appear to glow translucently (in varying shades of blue). Such occurrences glow brightly enough ...
