The Coriolis Effect causes water to be pushed onto shore and when the water on the surface of the sea becomes denser than the water beneath it, it sinks.

How is wind driven ekman transport related to coastal upwelling and downwelling?
They are both wind driven, if the Ekman Transport is moving in towrds the shore then downwelling will pull water from it and move it down and out. While when the Ekman Transport is moving out away from shore up welling will pull water up and feed the Transport. Note all directions are based on 90 degrees to the left or right fo the wind direction depending on wich Hemisphere.
How salinity and temperature affects the seawater?
Salinity and temperature are conservative properties of seawater that directly affect the density of seawater. This is an extremely important property because it in turn directly affects upwelling and downwelling of oceans and some major oceanic currents. This is because if a denser body of water is sitting on top of a less dense body of water, the denser part of the water column will turn over (sink) to get to a more stable water column state. This leads to water mixing of nutrients and oxygen for organisms living in the water column. Typically the saltier the water, the higher the density and also the colder the water, the higher the density. So because of this, cold and salty water (Antarctic and Arctic) are the most dense bodies of water and typically stay towards the bottom of the ocean floor.
What downwelling defined as?
Downwelling is the process of accumulation and sinking of higher density material beneath lower density material. A common example is convection currents in fluids.
What are the upwelling and downwelling compare and contrasted?

Upwelling and downwelling?
Upwelling is caused by currents on the surface. When water moves from the bottom of the ocean towards the surface it is called upwelling. Downwelling is when more dense water sinks. This process moves nutrients back to the deep part of the ocean.
How do subsurface lake waters cool down in the fall?
Upwelling/downwelling, do some research on these.

Upwelling is important to sealife because?
Downwelling is the process of accumulating higher density material beneath lower-density material, which can create currents along with the inverse process of upwelling. This is important for deep-sea creatures because it helps regulate the temperature of the oceans.
What is some natrally occurring electricity?
Lightening. The upwelling and downwelling of the wind causes charges to develop in the cloud. When the lowest point of the cloud has a lot of negative charge and the ground, trees, buildings, etc has a strong positive charge, the charges move toward each other (opposite charges attract) and therefore we see a lightening.

How can thermohaline circulation regulate climate?
It is gravity that drives thermohaline circulation. It's a gravity current. We usually apply the term thermohaline circulation to the deep ocean currents that are driven by gravity. Colder water or water that has a higher salt content than other water is more dense, and gravity will act on it to pull it "down" deeper. It will displace warmer or less salty water and move to greater depths. This sets the stage for a deep ocean current we call a thermohaline expressway. Use the links below for more information on gravity currents (which are sometimes called density currents)._______________________sflo:I would say this answer is limited in explaining what drives thermohaline circulation. Changes in density certainly affect circulation, particularly when water emerges from the deep or submerges to depths (upwelling and downwelling), but the effects of "gravity" on water masses of varying densities aren't a driver of circulation, per se. I would like to point that within the "thermohaline circulation," "thermo-" and "haline" are both components of the name. Thus in a more elemental manner, it makes more sense to explain this phenomenon by temperature and salinity differences, as well as the resulting changes in density, rather than merely "gravity."For a great snap-shot of our current understanding (or rather lack-therof) of the thermohaline circulation, what drives it, and how it affects or is affected by climate, please look-up:"Thermohaline circulation: The current climate" Nature421, 699 (13 February 2003) | doi:10.1038/421699a == ==
Is a Hawaiian bobtail squid Hawaiian?
YesEuprymna scolopes, commonly known as the Hawaiian Bobtail Squid, is a very small cephalopod about 33 millimeters long. It is endemic to the waters surrounding the Hawaiian islands and lives in a shallow water (2-4 cm deep) habitat. It is a largely nocturnal animal that buries itself in the sand during the daytime. This hiding behavior is very effective. The squid will nestle itself down into the substrate and use its tentacle arms to pull sand and gravel up over its body, only leaving its eyes bare and uncovered. [Watch a video]. Its life history shows a very short life span, reaching sexual maturity at 2 months and dieing anywhere between 3 and 10 months. It is a semelparous species, reproducing once in its lifetime. It has been suggested that E. scolopes has a high level of neural complexity, on par with more behaviorally advanced cephalopod molluscs (Wood 1999).In the wild, E. scolopes is commonly predated by the monk seal. It's main food source is shrimp, although it has been fed brine shrimp, mysids, mosquitofish, octopus and prawns in the laboratory (Wood 1999).E. scolopes has been studied largely in investigations of its use of bacterial symbionts in bioluminescence. Hypothetically, a better understanding of this type of mutualism could allow geneticists to implant V. fischeri in other organisms and make them luminesce as well. Juveniles are born without bacteria and must acquire them from the sea water. The bilobed light organ of a young squid has ciliated arms that sweep the bacteria into a crypt where they can colonize. Individual crypts are sealed off and the organ will be modified for adulthood, losing the arms. Once the colony has taken up residence, the bacteria mutate, decrease in size, lose their flagella and begin to glow. This process takes several hours and after a few weeks the entire squid has become fully colonized (Graf 2005).An interesting physiological attribute of the Bobtail squid is their use of extraocular photosensitive vesicles. Jones and Nishiguchi led the first experiment to demonstrate counterillumination by E. scolopes. As an artificial light source was increased and decreased in intensity, each squid adjusted its luminescence accordingly. As downwelling light increased, so did ventral emissions, up to a point where ventral emissions decreased. It was suggested that this pattern illustrated that light emission was controlled in a rapid, practical manner to down-welling light. The reduced emission at high light levels is probably an energy saving device used when counterillumination is no longer effective. It is important to note that counterillumination is still considered a theory, and little research has been done to quantify the reduction in predation of animals that exhibit this behavior. Nevertheless, the phenomenon is fascinating.See related link for more info
