OCEANOGRAPHY

OCEANOGRAPHY

  • the scientific study of the physical chemical , and biologial aspects of the Ocean.

MAJOR SUB-DIVIVISION OF OCEANOGRAPHY

PHYSICAL OCEANOGRAPHY

  • It deals with the study of Ocean Currents, tider, wave formation. and the energy exchange between The ocean and the atmosphere.
  • Physical oceanography concentrates on portraying and comprehension the advancing examples of sea flow and smooth movement, alongside the dispersion of its properties, for example, temperature, saltiness and the convergence of broke up concoction components and gasses. The sea as a dynamic liquid is learned at an extensive variety of spatial scales, from the centimeter scales significant to turbulent microstructure through the numerous thousand kilometer sizes of the sea gyres and worldwide upsetting flow. Approaches incorporate hypothesis, direct perception, and PC reproduction. Our examination oftentimes happens with regards to essential multidisciplinary issues including the elements and consistency of worldwide atmosphere and the maintainability of human use in beach front and estuarine districts.

CHEMICAL OCEANOGRAPHY

  • It deals with the study of chemical substances and properties of water in the ocean.
  • Chemical Oceanography is fundamentally interdisciplinary. The chemistry of the ocean is closely tied to ocean circulation, climate, the plants and animals that live in the ocean, and the exchange of material with the atmosphere, cryosphere, continents, and mantle.

BIOLOGICAL OCEANOGRAPHY

  • It Deals with the study of living organisms in the oceans and the Interrelationship of marine life and its Oceanic Environment.
  • Microbiology of extreme environments - The study of microbes in high pressure deep sea environments, physiology of survival and growth and high temperatures and in sea ice.
  • Phytoplankton Ecology - Physiology, genetic diversity and genomics of the oceans primary producers
  • Food web dynamics - Interactions between zooplankton, phytoplankton and protists, their distributions in time and space, connections between individual behavior and populations level demographics.

SUBMARINE GEOLOGY

  • It deals with the study of crust beneath the oceans.

Charybdis by William Pye is an installation with a spinning vortex that can be observed from multiple levels.

About the piece:

The sirens Charybdis and Scylla resided in the Sicilian Sea. Homer tells us that because Charybdis had stolen the oxen of Hercules, Zeus struck her with a thunderbolt and changed her into a whirlpool whose vortex swallowed up ships. In Charybdis the circular movement of water inside a transparent acrylic cylinder forms an air-core vortex in the centre. Steps wrap around the cylinder and allow spectators to view the vortex from above. 

How it works:

An air-core vortex is generated within a circular dish. Water rises and falls within the dish in a cyclic program of water activity. When the system is full and flowing over the perimeter and down the sides, the top surface is comparatively flat and smooth, only broken by the vortex in the middle. However, as the level drops, the body of water seems to take on a life of its own, increasingly rocking and swaying as its volume diminishes unaided by any outside force.
