Ocean color is the branch of ocean optics that specifically studies the color of the water and information that can be gained from looking at variations in color. The color of the ocean , while mainly blue, actually varies from blue to green or even yellow, brown or red in some cases. [ 1 ]
Ocean chlorophyll concentration is a proxy for phytoplankton biomass. In this map, blue colors represent lower chlorophyll and reds represent higher chlorophyll. Satellite-measured chlorophyll is estimated based on ocean color by how green the color of the water appears from space.
The color of the water as seen by satellites is known as ocean color. While ocean color is a key theme of ocean optics, optics is a broader term that also includes the development of underwater sensors using optical methods to study much more than just color, including ocean chemistry, particle size, imaging of microscopic plants and animals ...
Human-driven climate change is altering the world’s oceans, including their very color.
In the Netherlands, a project called the Citizen’s observatory for Coast and Ocean Optical Monitoring (Citclops) project has begun crowdsourcing water color measurements from citizen scientists. Citizen scientists estimate the color of the water with the Forel-Ule scale using a smartphone app called “Eye on water.” [ 4 ] [ 5 ] [ 6 ]
Ocean Color from July 2002 to March 2017 – NASA Aqua satellite. This visualization, derived using data from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard NASA’s Aqua satellite, shows monthly sea surface chlorophyll from July 2002 through February 2016. Chlorophyll is a proxy for phytoplankton abundance.
Water Remote Sensing is the observation of water bodies such as lakes, oceans, and rivers from a distance in order to describe their color, state of ecosystem health, and productivity. Water remote sensing studies the color of water through the observation of the spectrum of water leaving radiance.
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.
