The '''Sinking Ship Effect''' is an effect by which distant bodies appear to sink into the surface of the earth. This effect was used as a direct proof in ancient times for the earth's spherical nature, and is a main reason for mankind's adoption of the globular hypothesis.
#REDIRECT [[Sinking Ship Effect Caused by Refraction]]
In ''Earth Not a Globe'' its author discovers that this effect is inconsistent. Sometimes it occurs, and at other times it does not occur. A distant body such as a lighthouse will sometimes seem to be obscured, and that at other times the lighthouse will be revealed, allowing the observer to see further than the globe earth should allow. Rowbotham says that the sinking ship effect is most likely to occur when the weather is not calm and the observations are conducted over hectic ocean environments. In more landlocked areas such as lakes, canals, and ocean inlets, and under calm conditions, the effect is less likely to occur. This inconsistent nature of the effect is contrary to the argument that the sinking effect must the result of a spherical earth.
With the advent of photography and time-lapse photography we can analyze this phenomenon closely to determine its true nature, observing that not only is the effect inconsistent, it is not a perfect effect either.
The phenomenon of "sinking" is a known effect of atmospheric refraction. In ''Physics of the Air'' By [ Dr. William Jackson Humphreys] we [ read a description on p.449:]<br><br>
==Skunk Bay Timelapse==
The Skunk Bay Timelapses were taken by the [ Skunk Bay Weather] organization with zoom photography, showing a dynamic refraction effect on a peninsula in the distance. The distant peninsula is at times hidden and revealed. Below are high resolution versions of all available timelapse of the Skunk Bay peninsula scenes.
===09/07/12 Timelapse===
[ 09/07/12 Timelapse]<br>
On this day there was a mixture of sunken and visible effects.
===09/06/12 Timelapse===
[ 09/06/12 Timelapse]<br>
On this day the sinking effect comes and goes. The peninsula was sunken throughout most of the day.
===09/01/12 Timelapse===

On this day the peninsula sinking effect also comes and goes. The peninsula was visible throughout most of the day.
===Skunk Bay Peninsula Revealed===
At times over the course of a day, for long periods, the opposite peninsula is seen to be fully revealed:

===Skunk Bay Peninsula Sunken===
At other times of the day, and for long periods, the opposite bay appears to be sunken.

When the sunken scene is observed closely, and compared with the revealed version, we see that it is not a perfect effect. The sunken version contains vertical compression and squishing of bodies near the surface.
===Skunk Bay Peninsula Transition===
Below is an animation of the transition effect between sunken and revealed scenes. The Inferior Mirage, denoted by its characteristic  upside-down mirroring effect, decompresses from near the water surface and disappears, leaving behind the revealed scene of the peninsula.
From the above content we learn that the sinking effect can happen for long periods of time over a single day. The sinking effect is seen to happen repeatedly over multiple days, in all available timelapses of that peninsula. There is some compression near the surface in the sunken version of the scene; it is not a perfect effect. At the transition boundary an inferior mirage is seen to compress and decompress.
==Soundly Timelapse==
A YouTube author named Soundly is famed for the Lake Pontchartrain Power Line and Little Tensas Bayou photographs, which have been popularized to, supposedly, show evidence of the earth's curvature.

Firstly, the reader should note that, if that curvature seen the photograph were actually the curvature of the earth, the image would suggest that earth is very small.
Soundly provides several pieces of media from that bridge area, including a [ timelapse taken over a long period of time]. The following is taken from that timelapse, by Ranty, showing that light bends up and down over time:

'''Mirages in a Bottle'''<br>
[ Link to Paper]
Abstract: "A simple experiment is presented to visualize inferior and superior mirages in the laboratory. A quantitative analysis is done using ray tracing with both photographic and computational techniques. The mirage's image, as seen by the eye or the camera lens, can be used to analyze the deflection and inversion of light rays."

'''Flat Earth v. Sinking Comparison'''<br>
Ben, Taboo Conspiracy, reports that [ sometimes he is able to see further than the curvature of the earth should allow, and at other times things appear sunken.] He compares the two scenes. In his comparison the sunken scene was more distorted than the flat earth scene. Does refraction make things blurrier or clearer?
