These "watermark moments" in my life are occasions in time when one decision resulted in me reaching a high level of performance. The performance was too strong to sustain regularly, so it faded slightly and left a mark at the peak... a watermark. These events all happened before I was 20 years old.
The first such event was when I decided to learn how to swim. I knew this would be difficult because I was born without a spine. However, I studied swimming for more than six months before I actually went into the pool for myself. I can now hold my head under water for a long time!
The second such event was when I decided to learn guitar. I didn't know anyone who could play, so I decided to study by myself. After about a year of practice, I went to a music store and bought a book on guitar technique. Since then, I've been playing weekly with a group of friends.
Are these events important for me? Yes, because without them, I wouldn't have developed as a musician or as a swimmer.
Do other people experience watermark moments? Absolutely. It's very common for young athletes to reach a certain level of performance that doesn't last because they don't maintain their focus or they change directions. When this happens, they leave a mark behind like a watermark on a river bed.
A high water mark is a location that symbolizes a body of water's highest rise over land. A high water mark is frequently the consequence of a flood, but it can also represent an all-time high, an annual high (the maximum level to which water reached that year), or the high point for any other time division. High waters can cause damage by way of erosion, flooding, or other hazards.
The U.S. Geological Survey (USGS) defines a high water mark as "a surface formed by the highest recorded tide or flood." The term is most commonly used to describe locations on coastlines where higher tides or floods have caused sediment to be deposited out of reach of the low tide line, thus raising the sea wall or other shore protection structure above its normal position.
In geology, high waters are areas where rock has been exposed by erosion or where caves or holes have been dug into the earth's surface. High waters may also refer to regions of extremely high ground pressure that can cause rocks to be dislodged or torn from their places in the Earth's crust.
High waters can also be found inside bodies of water. Here, the term refers to areas where the water's surface is at a height greater than anywhere else within the body of water. This happens when water levels are high enough to overflow its banks, causing inland flooding. On lakes and oceans, high waters can occur after significant rainstorms or during spring runoff seasons when the snowpack melts rapidly.
Lateral markers are buoys and other markers that designate the boundaries of safe water zones. As you arrive from the open sea or move upstream, green colors, green lights, and odd numbers identify the boundary of a channel on your port (left) side. As you get upstream, the numbers frequently increase. Yellow colors, yellow lights, and even numbers indicate the zone on your starboard (right) side. These colors and markers also help guide large ships through narrow channels.
The distance between lateral markers is called their "marker-to-marker width." The minimum recommended marker-to-marker width for most channels in North America is 1,000 feet (300 m). However many channels have been modified over time by dredging or other activities to allow for channels with a marker-to-marker width of 500-600 feet (150-180 m). Large ships need more space than this amount of room to navigate safely. They should avoid crossing paths as far away as possible to prevent accidents caused by close calls with lateral markers.
Lateral markers are used not only to define channel edges but also to mark underwater hazards such as rocks, reefs, and sandbars. This allows boaters to select safer routes while avoiding dangerous areas. Lateral markers can be either fixed or floating. Fixed markers are anchored to the bottom and cannot be moved unless removed by federal officials. Floating markers stay within eyesight but can be pushed around by currents or waves.
Watermark electrotype An electro-type is a light watermark in which the color has been'strained' to produce a striking contrast with the surrounding surface. This permits it to be easily read but makes forgery tough. Electrotypes are used primarily for mass production of printed material, such as postage stamps and banknotes.
Electrotyping involves using a stencil or master to apply ink to paper or other materials. The ink on the material is made into an electrotype by passing the material through a series of baths containing salts that will dissolve or disperse the ink molecules. The resulting mixture is then molded under pressure into small cubes about one inch on each side. These in turn are placed in an acid bath to remove any remaining salt and then washed thoroughly with water before being dried.
The process can be repeated as often as necessary to obtain the required depth of type. For example, an eight-part typeface might require up to four sets of molds. Each set of molds will produce identical pieces, which are then used to print a single copy. Once these copies have been printed, they are removed from the machine and either destroyed or stored for future use.
Electrotypes were first produced around 1872. They quickly became popular because of their ease of use: anyone with a little training could operate the machine.
