Sea State 5 and 8 range. In oceanography, sea state is the general condition of the free surface on a large body of water—with respect to wind waves and swell —at a certain location and moment. A sea state is characterized by statistics, including the wave height, period, and spectrum. The sea state varies with time, as the wind and swell ...
The Sea Dragon was a 1962 conceptualized design study for a two-stage sea-launched orbital super heavy-lift launch vehicle. The project was led by Robert Truax while working at Aerojet, one of a number of designs he created that were to be launched by floating the rocket in the ocean. Although there was some interest at both NASA and Todd ...
Marine isotope stages ( MIS ), marine oxygen-isotope stages, or oxygen isotope stages ( OIS ), are alternating warm and cool periods in the Earth's paleoclimate, deduced from oxygen isotope data derived from deep sea core samples. Working backwards from the present, which is MIS 1 in the scale, stages with even numbers have high levels of ...
A sea is a large body of salty water. There are particular seas and the sea. The sea commonly refers to the ocean, the wider body of seawater . Particular seas are either marginal seas, second-order sections of the oceanic sea (e.g. the Mediterranean Sea ), or certain large, nearly landlocked bodies of water. The salinity of water bodies varies ...
The Sangamonian Stage (or Sangamon interglacial) is the term used in North America to designate the Last Interglacial (130,000-115,000 years ago) and depending on definition, part of the early Last Glacial Period, corresponding to Marine Isotope Stage 5 (~130-80,000 years ago). While often historically considered equivalent in scope to MIS 5 ...
Sea level above present day 180 m; rising to 220 m in Caradoc and falling sharply to 140 m in end-Ordovician glaciations [8] The Ordovician ( / ɔːr d ə ˈ v ɪ ʃ i . ə n , - d oʊ -, - ˈ v ɪ ʃ ən / or-də- VISH -ee-ən, -doh-, - VISH -ən ) [9] is a geologic period and system , the second of six periods of the Paleozoic Era .
Marine Isotope Stage (MIS) 5e, called the Eemian (Ipswichian in Britain) around 124,000–119,000 years ago, was the last interglacial period before the present (Holocene), and compared global mean surface temperatures were at least 2 °C (3.6 °F) warmer. Mean sea level was 4–6 m (13–20 ft) higher than at present, following reductions of ...
The Wilson Cycle is a model that describes the opening and closing of ocean basins and the subduction and divergence of tectonic plates during the assembly and disassembly of supercontinents. A classic example of the Wilson Cycle is the opening and closing of the Atlantic Ocean. It has been suggested that Wilson cycles on Earth started about 3 ...
