| Terms for subject Environment (6310 entries) |
| okeāna klimats | oceanic climate (A regional climate which is under the predominant influence of the sea, that is, a climate characterized by oceanity; the antithesis of a continental climate) | |
| okeāna piesārņošana | ocean dumping (The process by which pollutants, including sewage, industrial waste, consumer waste, and agricultural and urban runoff are discharged into the world's oceans. These pollutants arise from a myriad of sources) | |
| okeāna straume | ocean current (A net transport of ocean water along a definable path) | |
| okeāna temperatūra | ocean temperature (A measure, referenced to a standard value, of the heat or coldness in a body of oceanic water) | |
| okeāna virsmas un gaisa mijiedarbības aspekti | ocean-air interface (The sea and the atmosphere are fluids in contact with one another, but in different energy states - the liquid and the gaseous. The free surface boundary between them inhibits, but by no means totally prevents, exchange of mass and energy between the two. Almost all interchanges across this boundary occur most effectively when turbulent conditions prevail. A roughened sea surface, large differences in properties between the water and the air, or an unstable air column that facilitates the transport of air volumes from sea surface to high in the atmosphere. Both heat and water (vapor) tend to migrate across the boundary in the direction from sea to air. Heat is exchanged by three processes: radiation, conduction, and evaporation. The largest net exchange is through evaporation, the process of transferring water from sea to air by vaporization of the water) | |
| Okeānija | Oceania (The islands of the southern, western and central Pacific Ocean, including Melanesia, Micronesia, and Polynesia. The term is sometimes extended to encompass Australia, New Zealand, and the Malay Archipelago) | |
| okeanogrāfija | oceanography (The scientific study and exploration of the oceans and seas in all their aspects) | |
| okeāns | deep sea (Region of open ocean beyond the continental shelf) | |
| okeāns | ocean (The mass of water occupying all of the Earth's surface not occupied by land, but excluding all lakes and inland seas) | |
| oksidējamība | oxidising properties | |
| oksidējoša viela | oxidising agent (Compound that gives up oxygen easily, removes hydrogen from another compound, or attracts negative electrons) | |
| oksidējošs materiāls | oxidizable material (Substance that can undergo a chemical reaction with oxygen) | |
| oksidēšanās | oxidation (A chemical reaction that increases the oxygen content of a compound) | |
| oksidēšanās-mazināšanās | oxidation-reduction (An oxidizing chemical change, where an element's positive valence is increased (electron loss), accompanied by a simultaneous reduction of an associated element (electron gain)) | |
| oksīds | oxide (Binary chemical compound in which oxygen is combined with a metal or nonmetal) | |
| ola | egg (A large, female sex cell enclosed in a porous, calcareous or leathery shell, produced by birds and reptiles) | |
| olbaltums | protein (Any of a class of high-molecular weight polymer compounds composed of a variety of alfa-amino acids joined by peptide linkages) | |
| olfaktometrija | olfactometry (The testing and measurement of the sensitivity of the sense of smell) | |
| olīveļļas fabrikas notekūdeņi | olive oil mill wastewater (Aqueous residue deriving from the process of oil extraction from olives; it is composed of the olive-combined water and of the water used in the extraction and washing processes. It also contains a certain percentage of mineral compounds and of organic substances that are only partially biodegradable) | |
| onhocerikoze | onchocerciasis (Infection with the filaria Onchocerca volvulus; results in skin tumours, papular dermatitis, and ocular complications) |
