Natural lines of drift are those paths across terrain that are the most likely to be used when going from one place to another. These paths are paths of least resistance: those that offer the greatest ease while taking into account obstacles (e.g. rivers, cliffs, dense unbroken woodland, etc.) and modes of transit (e.g. pedestrian, automobile, horses.).
ESO Science Data Archive. The European Southern Observatory Catalog is an astronomical catalog that contains a log of observations performed with the ESO telescopes at La Silla and Paranal observatories, including the APEX submillimeter telescope on Llano de Chajnantor, as well as the UKIDSS/WFCAM data obtained at the UK Infrared Telescope facility in Hawaii.
A feature of the geology of England, the Needwood Basin extends beneath the eastern part of the Midlands county of Staffordshire.It is a depositional basin which was initiated during the Permian period and continued to receive sediment during the Triassic period and perhaps thereafter.
An Electronic Navigational Chart (ENC) is a digital representation of a real-world geographical area for the purpose of Marine navigation.Real-world objects and areas of navigational significance, or to a lesser degree - informational significance, are portrayed through Raster facsimiles of traditional paper charts; or more commonly through vector images, which are able to scale their relative ...

Depths which have been measured are indicated by the numbers shown on the chart. Depths on charts published in most parts of the world use metres. Older charts, as well as those published by the United States government, may use feet or fathoms. Depth contour lines show the shape of underwater relief. Coloured areas of the sea emphasise shallow ...
Drift is often subdivided into unstratified (unsorted) drift (glacial till) that forms moraines and stratified drift (glaciolacustrine and fluvioglacial sediments) that accumulates as stratified and sorted sediments in the form of outwash plains, eskers, kames, varves, and so forth. The term drift clay is a synonym for boulder clay. Both are ...
A tuck seine or tuck net about 70 fathoms (420 ft; 130 m) long, and very deep in the middle, was used to take fish from a larger seine. A line attached to a whaling harpoon was about 150 fathoms (900 ft; 270 m). A forerunner — a piece of cloth tied on a ship's log line some fathoms from the outboard end — marked the limit of drift line. [25]
