Tides are the rise and fall of sea levels caused by the combined effects of gravitational forces exerted by the Moon, Sun, and rotation of the Earth.
The times and amplitude of tides at a locale are influenced by the alignment of the Sun and Moon, by the pattern of tides in the deep ocean, by the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see Timing). Some shorelines experience a semi-diurnal tide - two nearly equal high and low tides each day. Other locations experience a diurnal tide - only one high and low tide each day. A "mixed tide"; two uneven tides a day, or one high and one low, is also possible.
Tides vary on timescales ranging from hours to years due to a number of factors. To make accurate records, tide gauges at fixed stations measure the water level over time. Gauges ignore variations caused by waves with periods shorter than minutes. These data are compared to the reference (or datum) level usually called mean sea level.
Tides is a donor advised fund that directs money to politically liberal causes. Founded in 1976 in San Francisco, Tides provides money to organizations working to advance progressive policy in the areas of the environment, health care, labor issues, immigrant rights, gay rights, women's rights and human rights. Tides oversees the Tides Center, which serves as an incubator for fledgling progressive organizations.
Tides was founded in 1976 by Drummond Pike. Jane Bagley Lehman, heir to the R. J. Reynolds Tobacco Company fortune, was also involved with the founding of Tides. Tides was conceived as a nationally oriented community foundation, and founded out of Pike's frustration with established philanthropy's perceived neglect of progressive issues. Drummond founded a similar organization, Tides Canada, in 2000.
Tides grew to become the most frequently used donor advised fund for wealthy West Coast liberals who did not want to start their own family foundations. By 2009, Tides was responsible for allocating $75 million per year in donor money, most of which went to fund progressive political causes.
Tides is the second full-length studio album by English electronic musician Phaeleh. It was released in July 2013 by Afterglo Records.

Azeem Ismail (born July 17, 1977 in New Brunswick, New Jersey), better known simply as Azeem is a performance poet and hip-hop MC, residing in Brooklyn, New York.
Azeem, born of Jamaican and Panamanian descent started his first band, Telefunken, in 1991, which was a combination of live instrumentation and hip-hop. Their first release came out in 1994 on the then newly formed Om Records.
Azeem's first break as a solo artist came at an open mic competition where he performed under the alias the "Invisible Man" against fifty other poets and lyricists for a spot on the Lollapolooza Tour.
This led to a PBS special (United States of Poetry) with Washington Square Films, and two book publishings.
In 1997, Azeem was hired by Bay Area artist, Michael Franti (The Disposable Heroes of Hiphoprisy and Spearhead) to assist him in composing songs for the second Spearhead album, Chocolate Supa Highway. This led to Azeem touring, writing, and performing with the band for two years. The single "Keep Me Lifted", a song that features Azeem, was the only song from the album to reach Billboard's Rap Charts.
