The dew point of an air parcel is the temperature to which it must cool before water vapor in the air begins to condense. Condensation in the atmosphere forms cloud droplets. Also, a net condensation of water vapor occurs on surfaces when the temperature of the surface is at or below the dew point temperature of the atmosphere.
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]
The Intergovernmental Panel on Climate Change predicts that should air temperatures increase by 1.4 degrees, there will be a 5% to 6% decrease in rainfall, increased frequency and intensity of extreme weather events (including a 66% increase in hurricane intensity), and a 0.5- to 0.6-meter sea-level rise in the Caribbean Netherlands.
The most significant ecosystems in the Gulf are mangrove forests, seagrass beds, and coral reefs, these being some of the most productive ecosystems on Earth, in terms of mean net primary productivity, and some of the most vulnerable to changes in water quality. [50] [48]
Glacial rock flour makes New Zealand's Lake Pukaki a lighter turquoise than its neighbors. The presence of color in water does not necessarily indicate that the water is not drinkable. Water with high water clarity is generally more cyan in color due to low concentrations of particles and/or dissolved substances. Color-causing particulate ...
The Caribbean is home to about 9% of the world's coral reefs, covering about 50,000 km 2 (19,000 sq mi), most of which are located off the Caribbean Islands and the Central American coast. [14] Among them, the Belize Barrier Reef stands out, with an area of 963 km 2 (372 sq mi), which was declared a World Heritage Site in 1996.
Water vapor concentration for this gas mixture is 0.4%. Water vapor is a greenhouse gas in the Earth's atmosphere, responsible for 70% of the known absorption of incoming sunlight, particularly in the infrared region, and about 60% of the atmospheric absorption of thermal radiation by the Earth known as the greenhouse effect.

Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
