So if the seawall's top elevation is 9’ high, how could it stop a 12’ tide? To answer that, we need to cover another important detail: Land is measured one way, using the baseline set by the NAVD88 system. Tides are measured using a different baseline. Why do we measure tides ...
Every place on Earth is measured in terms of its distance east or west of theprime meridian(0°longitude) in Greenwich,London, United Kingdom. This is also the reference point forCoordinated Universal Time(UTC) with 1 hour per 15 degrees longitude. You have to divide the longitude, in degr...
Here we show how major rivers can efficiently connect to the deep-sea, by analysing the longest runout sediment flows (of any type) yet measured in action on Earth. These seafloor turbidity currents originated from the Congo River-mouth, with one flow tr
(directly overhead) is labeled the zenith. The zenith angle is measured from the zenith point to the direction of the illumination source and is the 90 degrees complement to the altitude. To calculate the illumination angle, first convert the altitude angle to the zenith angle. Next, convert ...
When a satellite sends a signal, it creates a circle with a radius measured from the GPS device to the satellite. When we add a second satellite, it creates a second circle, and the location is narrowed down to one of two points where the circles intersect. With a third satellite, the...

When it is stated that "sea level is rising," this usually refers to "mean sea level," which is the average sea level around the earth based on numerous measurements over a long period of time. The elevation of mountain peaks are measured as the height of the peak of the mountain above...
