Process of discovering facts, processes, & unifying principles that explain nature of oceans & their associated life forms.; Involves physical, life & earth/space science
How much of the oceans have humans seen?
Very little of the ocean; about the size of a period on a page
What did the Phoenicians do for marine science?
Established first trade routes through mediterranean
earliest known regular open-seafaring beyond sight of land
voyages differ from other sea explores because he had science and exploration as only goals
explains that coral reefs form though process of coral growth as seafloor subsides/sinks
Remotely operated vehicle
Small, unmanned, sub w/ propellers, video camera and umbilical to surface
Autonomous underwater vehicle
Untethered robotic devices propelled through water by self-contained power systems& controlled/piloted by onboard computer
Theory of formation of planets
Some condensing gas revolving around sun collapsed into masses too small to become stars
Theory of evolution
says modern organisms and characterisitcs arose through processes of mutation and natural selection over millions of years
organisms that create NRG-rich compounds
plants, plankton (phytoplanton, zooplanton) Product carbon
most productive zone coastal temperate regions and subpolar regions have most productivity
bacteria with chlorophyll also called cyanobacteria. produce oxygen & take up carbon dioxide
representation of how NRG transfers from 1 level of organisms to another
lose 10% each level
molecules with positively and negatively charged ends
properties of water possible because polar
liquid @ room temp
principle of constant proportions
proportion of inorganic dissolved solids remain same relative to each other. sea salts
determines salinity by only measuring chlorinity of seawater
with do organisms need nitrogen
formation of organic compounds such as proteins, chlorophyll and nucleic acids
due to earth's rotation air moves faster at equator than at all poles
also affects air and water currents
currents deflect right in northern hemisphere and deflect left in southern hemisphere
combination of westerlies, trade winds and coriolis effect flow in each ocean basin
5 major gyers in each major ocean basin
What is the pattern of thermohaline circulation
redistributing heat through sinking of dense water, which causes deep water to ride and eventually enter surface currents
NRG transmission through matter
matter moves as wave passes, but returns to place of origin
Tsunamis don't destroy ships in open sea
because periods are so long that ships rise and fall very slowly when tsunami passes under them
formed when accumulated organic and inorganic particles are compressed and cemented together
Over next million years
Atlantic Ocean will expand, Pacific ocean will shrink, mediterranean sea close upa s africa moves north, east africa rift valley will have new ocean, southern california will pass san francisco and move northwest
originate from organisms, most abundant with respect to total volume, voer larger area of sea floor,
