Physical oceanography is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters.
Physical oceanography is one of several sub-domains into which oceanography is divided. Others include biological, chemical and geological oceanographies.
Mean sea level (MSL) is a datum representing the average height of the ocean's surface (such as the halfway point between the mean high tide and the mean low tide); used as a standard in reckoning land elevation. MSL also plays an important role in marine navigation as a chart datum and aviation, where standard sea level pressure is used as the measurement datum of altitude at flight levels. Detection of long-term variations of mean sea level requires careful measurement but can provide information on climate change. Over geologic time, sea levels have changed dramatically.
The domesticated turkey is a large poultry bird. The modern domesticated form descends from the wild turkey (Meleagris gallopavo), one of the two species of turkey (genus Meleagris). It was domesticated by the indigenous peoples of Mesoamerica at least 2,000 years ago, with the evidence pointing to what are today the central regions of Mexico.
Turkey meat is a popular form of poultry, and turkeys are raised throughout temperate parts of the world, partially because industrialized farming has made it very cheap for the amount of meat it produces. Female domesticated turkeys are referred to as hens and the chicks may be called poults or turkeylings. In the United States, the males are referred to as toms, while in Europe, males are stags. The average lifespan for a domesticated turkey is ten years.]citation needed[
