| θαλάσσια βιοκοινότητα | marine biocenosis | |
| θαλάσσια βιολογία | marine biology (A branch of biology that deals with those living organisms which inhabit the sea) | |
| θαλάσσια γεωλογία | marine geology | |
| θαλάσσια γεωλογία | marine geology (That aspect of the study of the ocean that deals specifically with the ocean floor and the ocean-continent border, including submarine relief features, the geochemistry and petrology of the sediments and rocks of the ocean bottom and the influence of seawater and waves on the ocean bottom and its materials) | |
| θαλάσσια εξόρυξη | offshore mining (Oil extraction from platforms situated a short distance from the coast) | |
| θαλάσσια εξόρυξη | offshore mining | |
| θαλάσσια ζώνη | maritime area | |
| θαλάσσια θερμοκρασία | ocean temperature (A measure, referenced to a standard value, of the heat or coldness in a body of oceanic water) | |
| θαλάσσια θερμοκρασία | ocean temperature | |
| Θαλάσσια και παράκτια ύδατα | marine and coastal water | |
| θαλάσσια κοινότητα | marine community | |
| θαλάσσια κυκλοφορία | sea circulation (Large-scale horizontal water motion within an ocean. The way energy from the sun, stored in the sea, is transported around the world. The currents explain, for example, why the UK has ice-free ports in winter, while St. Petersburg, at the same latitude as the Shetland Islands, needs ice breakers. Evidence is growing that the world's ocean circulation was very different during the last ice age and has changed several times in the distant past, with dramatic effects on climate. The oceans are vital as storehouses, as they absorb more than half the sun's heat reaching the earth. This heat, which is primarily absorbed near the equator is carried around the world and released elsewhere, creating currents which last up to 1.000 years. As the Earth rotates and the wind acts upon the surface, currents carry warm tropical water to the cooler parts of the world. The strength and direction of the currents are affected by landmasses, bottlenecks through narrow straits, and even the shape of the sea-bed. When the warm water reaches polar regions its heat evaporates into the atmosphere, reducing its temperature and increasing its density. When sea-water freezes it leaves salt behind in the unfrozen water and this cold water sinks into the ocean and begins to flow back to the tropics. Eventually it is heated and begins the cycle all over again) | |
| θαλάσσια ναυσιπλοΐα | maritime navigation (Travelling on the sea by means of boats, ships, etc.) | |
| θαλάσσια ναυσιπλοΐα | maritime navigation | |
| θαλάσσια οικολογία | marine ecology (An integrative science that studies the basic structural and functional relationships within and among living populations and their physical-chemical environments in marine ecosystems. Marine ecology focuses on specific organisms as well as on particular environments or physical settings) | |
| θαλάσσια πανίδα | marine fauna (Animals which live in the sea) | |
| θαλάσσια πανίδα | marine fauna | |
| θαλάσσια περιοχή | marine region | |
| θαλάσσια ρύπανση | marine pollution (Any detrimental alteration of the marine environment caused by the intentional or accidental release of dangerous or toxic substances, such as industrial, commercial and urban waste water) | |
| θαλάσσια ρύπανση (προερχόμενη) από χερσαίες πηγές | land-based marine pollution |
