Planktology
Planktology is the study of plankton, various small drifting plants, animals and microorganisms that inhabit bodies of water. Planktology topics include primary production, energy flow and the carbon cycle. Plankton drive the "biological pump", a process by which the ocean ecosystem transports carbon from the surface euphotic zone to the ocean's depths. Such processes are vital to carbon dioxide sinks, one of several possibilities for countering global warming. Modern planktology includes behavioral aspects of drifting organisms, engaging modern ''in situ'' imaging devices. Some planktology projects allow the public to participate online, such as the Long-term Ecosystem Observatory.

Plankton
Plankton are the diverse collection of organisms found in water (or air) that are unable to propel themselves against a current (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales. Marine plankton include bacteria, archaea, algae, protozoa and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. Freshwater plankton are similar to marine plankton, but are found in the freshwaters of lakes and rivers. Plankton are usually thought of as inhabiting water, but there are also airborne versions, the aeroplankton, that live part of their lives drifting in the atmosphere. These include plant spores, pollen and wind-scattered seeds, as well as microorganisms swept into the air from terrestrial dust storms and oceanic plankton swept into the air by sea spray.

Johannes Krey
Johannes is a Medieval Latin form of the personal name that usually appears as "John" in English language contexts. It is a variant of the Greek and Classical Latin variants (Ιωάννης, '' Ioannes''), itself derived from the Hebrew name '' Yehochanan'', meaning "Yahweh is gracious". The name became popular in Northern Europe, especially in Germany because of Christianity. Common German variants for Johannes are ''Johann'', ''Hannes'', '' Hans'' (diminutized to ''Hänschen'' or ''Hänsel'', as known from "''Hansel and Gretel''", a fairy tale by the Grimm brothers), '' Jens'' (from Danish) and '' Jan'' (from Dutch, and found in many countries). In the Netherlands, Johannes was without interruption the most common masculine birth name until 1989. The English equivalent for Johannes is John. In other languages *Joan, Jan, Gjon, Gjin and Gjovalin in Albanian *'' Yoe'' or '' Yohe'', uncommon American form''Dictionary of American Family Names'', Oxford University Press, 2013. *Ya� ...

Victor Hensen
Christian Andreas Victor Hensen (10 February 1835 – 5 April 1924) was a German zoologist and marine biologist ( planktology). He coined the term '' plankton'' and laid the foundation for biological oceanography and quantitative studies. Family Hensen was born in the town of Schleswig where his father ran a school for the deaf and dumb.

Sayed ElSayed
''Sayyid'' (, ; ar, سيد ; ; meaning 'sir', 'Lord', 'Master'; Arabic plural: ; feminine: ; ) is a surname of people descending from the Islamic prophet Muhammad through his grandsons, Hasan ibn Ali and Husayn ibn Ali, sons of Muhammad's daughter Fatima and his cousin and son-in-law Ali (Ali ibn Abi Talib). While in the early islamic period the title Al-Sayyid was applied on all the members of the of banu hashim, the tribe of Muhammad. But later on the title was made specific to those of Hasani and Hussaini descent, Primarily by the Fatimid Caliphs. Female ''sayyids'' are given the titles ''sayyida'', ''syeda'', ''alawiyah'' . In some regions of the Islamic world, such as in Iraq, the descendants of Muhammad are given the title '' amīr'' or ''mīr'', meaning "aristocrats", "commander", or "ruler". In Shia Islam the son of a non Sayyid father and a Sayyida mother claim the title Mirza. In Sunni Islam a person being a descendant of Muhammad, of either maternal or pa ...

Long-term Ecosystem Observatory
The Long-term Ecological Observatory (LEO) is a project off the coast of New Jersey, United States, which monitors the processes in the ocean with online IT systems, spearheaded by the Institute of Marine and Coastal Sciences at Rutgers University. Already installed are sensors for temperature, salinity, transmission, light, light attenuation, fluorescence, pressure and velocity. With improvements in Internet infrastructure it will be possible to observe and evaluate plankton (like copepods) or juvenile fish (like Atlantic herring) online with a quantitative ''in situ'' microscope, known as the ecoSCOPE, in order to get more insight into some of the enigmatic life histories of ocean organisms, like predator–prey interaction between herring and copepods, the Eel story, or oxygen depletion Hypoxia refers to low oxygen conditions. Normally, 20.9% of the gas in the atmosphere is oxygen. The partial pressure of oxygen in the atmosphere is 20.9% of the total barometric pressure ...
