marine

Examples of marine in the following topics:

• Marine Habitats

  • The marine environment supplies many kinds of habitats that support marine life.
  • The marine environment supplies many kinds of habitats that support life.
  • Marine life partially depends on the saltwater that is in the sea ("marine" comes from the Latin "mare," meaning sea or ocean).
  • Marine habitats can be modified by their inhabitants.
  • Coral reefs provide marine habitats for tube sponges, which in turn become marine habitats for fishes.

• Viral Roles in Ecosystems

  • This is typified by the role of viruses in marine ecology.
  • Viruses are the main agents responsible for the rapid destruction of harmful algal blooms, which often kill other marine life.
  • Like any organism, marine mammals are susceptible to viral infections.
  • As mentioned, marine viruses are mostly bacteriophages, or phages.
  • This represents a fraction of the viral diversity seen in teaspoon of marine water.

• Marine Biomes

  • The ocean and coral reefs make up two types of marine biomes where organisms are influenced by depth and light availability.
  • The ocean is the largest marine biome.
  • Within the ocean, coral reefs are a second kind of marine biome.
  • Nutrients are scarce in this less-productive part of the marine biome.
  • Coral reefs are ocean ridges formed by marine invertebrates living in warm, shallow waters of the ocean.

• Anoxic Hydrocarbon Oxidation

  • Marine environments are especially vulnerable.
  • Despite its toxicity, a considerable fraction of crude oil entering marine systems is eliminated by the hydrocarbon-degrading activities of microbial communities.
  • Anaerobic oxidation of methane (AOM) is a microbial process that occurs in anoxic marine sediments.
  • It is estimated that almost 90% of all the methane that arises from marine sediments is oxidized anaerobically by this process.
  • Describe the process of anoxic hydrocarbon oxidation in regards to marine environments

• Mobilization and the Development of the West

  • The Marine Corps created the Marine Corps Women's Reserve in 1943.
  • Captain Anne Lentz was its first commissioned officer and Private Lucille McClarren its first enlisted woman; the first detachment of female marines was sent to Hawaii for duty in 1945.
  • Marine women served stateside as clerks, cooks, mechanics, drivers, and in a variety of other positions.
  • Marine Corps were women.
  • Discuss women's increasing involvement in the army, air force, navy, marines, and coast guard, paying special attention to the involvement of women of color.

• Changing Roles for Women

  • The Marine Corps created the Marine Corps Women's Reserve in 1943.
  • That year, the first female officer of the United States Marine Corps was commissioned, and the first detachment of female marines was sent to Hawaii for duty in 1945.
  • The first director of the Marine Corps Women's Reserve was Mrs.
  • Marine women served stateside as clerks, cooks, mechanics, drivers, and in a variety of other positions.
  • Marine Corps were women.

• Sea Coral and Sea Anemone Zooxanthellae

  • Zooxanthellae refers to a variety of species that form symbiotic relationships with other marine organisms, particularly coral.
  • Cnidarians that are associated with Symbiodinium occur mostly in warm oligotrophic (nutrient-poor) marine environments where they are often the dominant constituents of benthic communities.

• Planctomycetes

  • Planctomycetes are a phylum of aquatic bacteria and are found in samples of brackish, marine, and fresh water.
  • They are found in samples of brackish, marine, and fresh water.

• The Phosphorus Cycle

  • Phosphorus is also reciprocally exchanged between phosphate dissolved in the ocean and marine ecosystems.
  • A dead zone is an area within a freshwater or marine ecosystem where large areas are depleted of their normal flora and fauna.
  • Phosphate dissolved in ocean water cycles into marine food webs.
  • Some phosphate from the marine food webs falls to the ocean floor, where it forms sediment.

• Psychrophilic Crenarchaeota

  • Initially, the Crenarchaeota were thought to be sulfur-dependent extremophiles but recent studies have identified characteristic Crenarchaeota environmental rRNA indicating the organism may be the most abundant archaea in the marine environment.
  • Beginning in 1992, data were published that reported sequences of genes belonging to the Crenarchaea in marine environments making these bacteria psychrophiles or cryophiles.
  • Different microbes are responsible for each step in the marine environment.
  • Several groups of ammonia oxidizing bacteria (AOB) are known in the marine environment, including Nitrosomonas, Nitrospira, and Nitrosococcus.
