Ayana Elizabeth Johnson (born 1980 or 1981 [5]) is a marine biologist, policy expert, and conservation strategist. She is the co-founder of Urban Ocean Lab, a think tank for ocean-climate policy in coastal cities, [2] [6] and the Roux Distinguished Scholar at Bowdoin College. [7]
Widder was a senior scientist and director of the Bioluminescence Department at the Harbor Branch Oceanographic Institution from 1989 to 2005. [8] Certified as a Scientific Research Pilot for Atmospheric Diving Systems in 1984, she holds certifications that qualify her to dive the deep diving suit WASP [2] as well as the single-person untethered submersibles DEEP ROVER and DEEP WORKER.

Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea. Given that in biology many phyla , families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy .
Jamieson's early scientific work focussed largely on technology-driven studies into deep-sea fish behaviour and pelagic bioluminescence.He completed two EU funded postdocs, the first a sediment dynamics project named COBO (Coastal Ocean Benthic Observatories [10]), that involved the design and construction of a deep-water Sediment Profile Imaging camera (SPI), the second was an astrophysics ...
Marine waters cover more than 70% of the surface of the Earth and account for more than 97% of Earth's water supply [1] [2] and 90% of habitable space on Earth. [3] Seawater has an average salinity of 35 parts per thousand of water. Actual salinity varies among different marine ecosystems. [4]
The development of marine biology as a scientific field was hampered by the incapacity to efficiently investigate these organisms in their native habitats. This problem was a significant pain point and was resolved by Villepreux-Power's idea, which helped scientists learn more about the biology and behavior of marine life.
The tables below present an example of an artificial seawater (35.00‰ of salinity) preparation devised by Kester, Duedall, Connors and Pytkowicz (1967). [1] The recipe consists of two lists of mineral salts, the first of anhydrous salts that can be weighed out, the second of hydrous salts that should be added to the artificial seawater as a solution.
