Pytheas also spoke of the waters around Thule and of those places where land properly speaking no longer exists, nor sea nor air, but a mixture of these things, like a "marine lung", in which it was said that earth and water and all things are in suspension as if this something was a link between all these elements, on which one can neither ...
Oblique view from Apollo 15, facing south Close up of the south wall of Pytheas crater from Apollo 17. Pytheas is a small lunar impact crater located on the southern part of the Mare Imbrium, to the south of the crater Lambert. It was named after ancient Greek navigator and geographer Pytheas of Massalia. [1]
The record of the voyage of Pytheas was lost in antiquity but was known to some later writers, including Timaeus, Posidonius, and Pliny the Elder. Their work is contradictory, but from it deductions can be made about what was reported by Pytheas. This “represents all that was known about the tin trade in the ancient classical world”. [1]
The Greek explorer Pytheas of the Greek city of Massalia (now Marseille, France) is the first to have written of Thule, after his travels between 330 and 320 BC. Pytheas mentioned going to Thule in his now lost work, On The Ocean Τὰ περὶ τοῦ Ὠκεανοῦ (ta peri tou Okeanou). L.
A seamount is a large submarine landform that rises from the ocean floor without reaching the water surface (), and thus is not an island, islet, or cliff-rock.Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height.
High and low tide in the Bay of Fundy. The theory of tides is the application of continuum mechanics to interpret and predict the tidal deformations of planetary and satellite bodies and their atmospheres and oceans (especially Earth's oceans) under the gravitational loading of another astronomical body or bodies (especially the Moon and Sun).
Pythia's Oasis is a cold seep on the ocean floor 50 miles (80 km) off the coast of Newport, Oregon, United States (1], characterized by a focused stream of highly altered fluid that is approximately 9 °C (16 °F) above normal ocean background temperature. Early results indicate "elevated flow rates" sustained for about 1,500 years.
The Bear Seamount (left), a guyot in the northern Atlantic Ocean. In marine geology, a guyot (/ ˈ ɡ iː. oʊ, ɡ iː ˈ oʊ /), [1] [2] also called a tablemount, is an isolated underwater volcanic mountain with a flat top more than 200 m (660 ft) below the surface of the sea. [3]
