Metres above sea level

Metres above mean sea level (MAMSL) or simply metres above sea level (MASL or m.a.s.l.) is a standard metric measurement in metres of the elevation of a location in reference to a historic mean sea level. Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level might differ from the actual elevation of a given location over sea level at a given moment.

Uses

Metres above sea level is the standard measurement of the elevation or altitude of:

How it is determined

The elevation or altitude in metres above sea level of a location, object, or point can be determined in a number of ways. The most common include:

Sea level

Sea level is generally used to refer to mean sea level (MSL), an average level for the surface of one or more of Earth's oceans from which heights such as elevations may be measured. MSL is a type of vertical datum – a standardised geodetic reference point – that is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured in order to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is the midpoint between a mean low and mean high tide at a particular location.

Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. The careful measurement of variations in MSL can offer insights into ongoing climate change, and sea level rise has been widely quoted as evidence of ongoing global warming.

The term above sea level generally refers to above mean sea level (AMSL).

SeeFood

SeeFood (Also known as Sea Level in USA) is Malaysia's first 3D animated movie in English. The film is produced by Silver Ant and released in Malaysian cinemas beginning 8 March 2012.

SeeFood was first launched in Poland on 7 October 2011. It received financial support from Ministry of Science, Technology and Innovation (Malaysia) (MOSTI) and also Multimedia Development Corporation (MDeC).

Storyline

It starts with Julius, a large shark, chasing Pup, but then we see that he was only pretending to hunt him. They come upon and speak about the amazing number of shark egg sacks lying on Pup's reef. Later, while Julius is off chasing a school of fish, two human divers suddenly appear to steal the shark egg sacks from the reef. Pup does everything he can to fend them off; almost being captured himself, but in the end the divers speed back to shore with all the eggs.

In the next scene, which begins with a factory polluting the ocean, Myrtle, a sea turtle, suffocating from a plastic bag around her head, but she finally frees herself of it. The bag drops further down to where Spin, a stingray, was swimming around and he later grab a discarded restaurant menu with his tail. Later on, he throw it to Julius's three pilot fish servants who will open the menu and show him there are other varieties of food, especially chickens, which are only found on land. But this is actually a plan of Spin and Myrtle to get rid of Julius. She and the fish bring him to a nearby beach, where Julius tries to eat a hen called Heather. He's nearly stranded on the land, but is able to make it back into the water.

Sea Level (band)

Sea Level is the name of a Southern rock/funk/fusion jam band that mixed jazz, blues and rock and existed between 1976 and 1981. Initially it was an offshoot of The Allman Brothers Band, but as tensions grew between the loss of two of its founding members and personal grievances between Gregg Allman and other band mates and associates, Sea Level took on a life of its own as an independent band.

After the initial breakup of the Allman Brothers Band when Gregg Allman and Dicky Betts left, most of the remaining members who evolved into Sea Level were the trio "We Three" comprising bassist Lamar Williams, drummer Jaimoe and Chuck Leavell (piano, keyboards, vocals). The trio would occasionally open shows for the group in 1975 and 1976. With the Allmans disbanding in 1976, the trio added guitarist Jimmy Nalls and named the band based on a phonetic pun of their new bandleader Chuck Leavell's name: "C. Leavell." They toured relentlessly, experimenting and refining their sound, eventually signing with Capricorn Records (home of the Allman Brothers) and recording their self-titled debut album in 1977.
