| Term: | Nilas |
| Definition: | A thin, elastic crust of ice bending easily on waves and swell. Nilas has a matte surface and is up to 4 in (- 10 cm) thick. Under pressure it thrusts into a pattern of inter- locking fingers (see FINGER-RAFTED ICE). May be subdivided into dark nilas and light nilas. |
| Term: | Nilas |
| Definition: | Sea ice terminology. Describes a thin, elastic crust of gray-colored ice that is formed on a calm sea, and is easily bent by waves and thrust into a pattern of interlocking fingers (known as finger rafting). Nilas has a matte surface, is up to 10 cm in thickness, and may be subdivided into dark nilas and light nilas. |
| Term: | Nilas |
| Definition: | A thin elastic crust of ice, easily bending on waves and swell and under pressure, thrusting in a pattern of interlocking 'fingers' (finger rafting). Has a matt surface and is up to 10cm in thickness. May be subdivided into dark nilas and light nilas. Dark nilas is 5cm thick and very dark in colour. Light nilas is 5-10cm thick and reflects proportionately more light than dark nilas, depending on its thickness. |
| Term: | Nilas |
| Definition: | A thin sheet of smooth, level ice less than 10 centimeters (4 inches) thick; appear darkest when thin. |
| Term: | Nilas |
| Definition: | A thin elastic crust of ice, easily bending on waves and swell and under pressure, thrusting in apattern of interlocking 'fingers' (finger rafting). Has a matt surface and is up to 10 cm in thickness. May be subdivided into dark nilas and light nilas. |
| Term: | Nilas |
| Definition: | A thin elastic crust of ice up to 10 cm thick that, under pressure, may deform by finger rafting. |
| Term: | Nilas |
| Definition: | A thin elastic crust offloating ice, easily bending on waves and swell and rafting under pressure. It has a matt surface and is up to 10 cm thick. When under about 5 cm in thickness it is very dark in colour; when more than 5 cm, rather lighter. |
