- Water column (Wikipedia)
The (oceanic) water column is a concept used in oceanography to describe the physical (temperature, salinity, light penetration) and chemical (pH, dissolved oxygen, nutrient salts) characteristics of seawater at different depths for a defined geographical point. Generally, vertical profiles are made of temperature, salinity, and other chemical parameters at a defined point along the water column. The water column is the largest, yet one of the most under-explored, habitats on the planet; it is explored to better understand the ocean as a whole, including the huge biomass that lives there and its importance to the global carbon and other biogeochemical cycles. Studying the water column also provides understanding on the links between living organisms and environmental parameters, large-scale water circulation, and the transfer of matter between water masses.
- Pharisees (Wikipedia)
The Pharisees (/ˈfærəsiːz/; Hebrew: פְּרוּשִׁים, romanized: Pərūšīm, lit. ‘separated ones’) were a Jewish social movement and school of thought in the Levant during the time of Second Temple Judaism. Following the destruction of the Second Temple in 70 AD, Pharisaic beliefs became the foundational, liturgical, and ritualistic basis for Rabbinic Judaism. Although the group no longer exists, their traditions are of great importance for the manifold Jewish religious movements.
