Page 315 - Said of circles on a sphere whose plane passes through the center of the sphere, such as the equator and meridians of longitude.
Page 196 - A table of tidal differences is given by means of which the tides at about 3,900 intermediate ports may be obtained. These tables are published in two volumes under the titles : Tide Tables, Atlantic Ocean, and Tide Tables, Pacific Ocean and Indian Ocean. Current tables are also issued annually in advance. They include daily predictions of the times of slack water and the times and velocities of strength of flood and ebb for a number of harbors, together with differences for obtaining predictions...
Page 311 - The plane of the ecliptic is inclined to the plane of the equator at an angle of 23°27'8'-26 which is very slowly decreasing. The angle is called the obliquity of the ecliptic.
Page 233 - That branch of applied science which deals with the measurement and description of the physical features of the navigable portion of the earth's surface and adjoining coastal areas, with special reference to their use for the purpose of navigation.
Page 227 - Gleichung sin l • sin 3 • sin 5 • sin 7 = sin 2 • sin 4 • sin 6 • sin 7[8] und deren ebenso zierlichen Differentialgleichungen hängen.
Page 233 - That science which deals with the measurement and description of the physical features of the oceans, seas, lakes, rivers and their adjoining coastal areas, with particular reference to their use for navigational purposes.
Page 321 - ... respect to meridian angle. coincides with the ecliptic plane, the declination angle can be nothing other than 0°. Figure A-6 shows the possible values of declination for orbits with various inclinations to the ecliptic plane. Note that the constant-inclination lines are plotted against the value of the angle between the line from the center of the earth to the center of the sun (which is contained in the ecliptic plane) and the projection on the ecliptic plane of the satellite orbit axis. If...

Page 261 - ... surveying, sound velocity varies but slightly from season to season. These variations can be determined and due allowance made in survey work. Soundings may be obtained while the boat proceeds at any speed and for the depth of which the apparatus is capable. Echo-sounding is the method used to measure the depth of water by determining the time required for sound waves to travel, at known velocity, from a point near the surface of the water to the bottom of the river or reservoir and return. Echosounding...
Page 227 - Hence, since the sines of the angles of a triangle are proportional to the lengths of the opposite sides...
