| sea (1. In general, the marine section of the globe as opposed to that of the land. 2. The name given to a body of salt water smaller than an ocean and generally in proximity to a continent) | mer | |
| sea bed (The bottom of the ocean. Also known as sea floor; sea bottom. The ocean floor is defined as the near-horizontal surface of the ocean basin) | fond marin | |
| sea bed exploitation (Marine mineral resources extend far beyond those presently exploited; minerals are derived from two separate types of marine sources: from sedimentary deposits underlying the continental shelves and from inshore deposits on the surface of the continental shelves. By far the most valuable of the mineral resources exploited from marine environments is petroleum. Offshore placer deposits on the surface of the continental shelves yield gold, platinum, and tin. On the floors of the world's oceans manganese nodules are found as a result of pelagic sedimentation or precipitation; they are small, irregular, black to brown, friable, laminated concretionary masses consisting primarily of manganese salts and manganese-oxide minerals) | exploitation des fonds marins | |
| sea bed mining | extraction minière sur le fonds marin | |
| sea bed mining (The activity or processes involving the extraction of mineral deposits from the surface, or below the surface, of the ocean floor) | extraction minière sur le fonds marin | |
| sea bird affected by oil | oiseau marin contaminé par les huiles | |
| sea cat | loutre de mer | |
| 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) | circulation maritime | |
