Sturgeon have different migration habits and can survive without ever visiting the ocean.

Animals in the water column are almost entirely dependent on primary production from living phytoplankton, while animals living on or in the ocean floor feed on detritus or can switch to detritus feeding.

Smaller transportation canals can carry barges or narrowboats, while ship canals allow seagoing ships to travel to an inland port ( e. g., Manchester Ship Canal ), or from one sea or ocean to another ( e. g., Caledonian Canal, Panama Canal ).

Another example can be found in the 1962 short story Epilogue by Poul Anderson, in which self-replicating factory barges were proposed that used minerals extracted from ocean water as raw materials.

Earthquakes that caused the greatest loss of life, while powerful, were deadly because of their proximity to either heavily populated areas or the ocean, where earthquakes often create tsunamis that can devastate communities thousands of kilometers away.

Halophiles can be found anywhere with a concentration of salt five times greater than the salt concentration of the ocean, such as the Great Salt Lake in Utah, Owens Lake in California, the Dead Sea, and in evaporation ponds.

Their origin can be traced back to the early Gulf of Mexico, when the shallow ocean had high rates of evaporation.

Finally, she finds an island that isn't attached to the ocean floor so it isn't considered land and she can give birth.

Although they spend most of their lives in the ocean, species such as gulls can often be found thousands of miles inland.

Marine habitats can be divided into coastal and open ocean habitats.

Large pipelines can crush sites and render some of their remnants inaccessible as pipe is dropped from the ocean surface to the substrate thousands of feet below.

The episode " Better Than Martians " ( 1994 ) deals with the first manned mission to Mars returning to Earth, but, encountering difficulty upon re-entering Earth's atmosphere and splashing into the ocean, leaving seaQuest to find the capsule before an unfriendly foreign confederation can.

With the Intertropical Convergence Zone ( ITCZ ) swinging northward over West Africa from the Southern Hemisphere in April, heavy showers coming from pre-monsoonal convective clouds mainly in the form of squall lines also known as the north easterlies formed mainly as a result of the interactions of the two dominant airmasses in Nigeria known as the Maritime tropical ( south westerlies ) and the Continental tropical ( north easterlies ), begins in central Nigeria while the Monsoons from the south atlantic ocean arrives in central Nigeria in July bringing with it high humidity, heavy cloud cover and heavy rainfall which can be daily occurrence lasting till September when the monsoons gradually begin retreating southward to the southern part of Nigeria. Rainfall totals in central Nigeria varies from in the lowlands of the river Niger Benue trough to over along the south western escarpment of the Jos Plateau.

There is another disturbance of the Earth's rotation called polar motion that can be estimated for only a few months into the future because it is influenced by rapidly and unpredictably varying things such as ocean currents, wind systems, and motions in the liquid nickel-iron outer core of the Earth.

Medium-sized ocean vessels can sometimes reach Asunción, but the twisting course and shifting sandbars can make this transit difficult.

Expressing surprise at the ignorance of the poets, Pliny says " There can be no doubt that amber is the product of the islands of the northern ocean ( Baltic Sea )" and attributes its introduction into the Po valley to the Veneti, the last link in a trade route to the north through Pannonia and Germany.

The deposit of rupees to the account of the Government of the United States of America in payment for the commodities and for ocean transportation costs financed by the Government of the United States of America ( except excess costs resulting from the requirement that United States flag vessels be used ) shall be made at the rate of exchange for United States dollars generally applicable to import transactions ( excluding imports granted a preferential rate ) in effect on the dates of dollar disbursement by United States banks, or by the Government of the United States of America, as provided in the purchase authorizations.

The terms are fairly safe to use on this side of the ocean, but before you start spouting them to your date, it might be best to find out if he was a member of Major Pockmanster's Delhi Regiment, since resentment toward the natives was reportedly very high in that outfit.

The early Greeks believed this ocean to be a gigantic river encircling the world.

The deep ocean floor is thought to be fairly flat with occasional deeps, abyssal plains, trenches, seamounts, basins, plateaus, canyons, and some guyots.

At the present time, approximately one third < ref > of human generated emissions are estimated to be entering the ocean.

Principal instrumentation for the study will be self-contained CO < sub > 2 </ sub > monitors placed on buoys in the ocean.

Even though life appears to be rather sparse in the deep ocean basins, energy and chemical effects in these deep basins could have far-reaching implications.

This appeared to be confirmed by the exploration of the deep sea beds conducted by the Challenger expedition, 1872-6, which showed that contrary to expectation, land debris brought down by rivers to the ocean is deposited comparatively close to the shore in what is now known as the continental shelf.

* Second, masses floating freely in a fluid substratum, like icebergs in the ocean, should be in isostatic equilibrium ( where the forces of gravity and buoyancy are in balance ).

' The sentient ocean that covers much of the surface of Solaris in Stanislaw Lem's eponymous novel also seems, from much of the fictional research quoted and discussed in the book, to be based on some element other than carbon.

Nereus, unlike Kaikō, did not need to be powered or controlled by a cable connected to a ship on the ocean surface.

The problem was initially thought to be serious enough that it might need to make an ocean landing ; life jackets and life rafts were made ready.

The C-isotope chemostratigraphic characteristics obtained for contemporaneous cap carbonates in different parts of the world may be variable in a wide range owing to different degrees of secondary alteration of carbonates, dissimilar criteria used for selection of the least altered samples, and, as far as the C-isotope data are concerned, due to primary lateral variations of δ < sup > l3 </ sup > C < sub > carb </ sub > in the upper layer of the ocean.

It is not certain what exact changes will happen to ENSO in the future: Different models make different predictions .< ref name =" Merryfield2006 "> It may be that the observed phenomenon of more frequent and stronger El Niño events occurs only in the initial phase of the global warming, and then ( e. g., after the lower layers of the ocean get warmer as well ), El Niño will become weaker than it was.

But by the 1st century AD, Pliny the Elder was in a position to claim that everyone agrees on the spherical shape of Earth, although there continued to be disputes regarding the nature of the antipodes, and how it is possible to keep the ocean in a curved shape.

The deep-draft breakwater will be capable of berthing large ocean liners within the " bay ", while the marina will accommodate 500 private boats.

Until recently, the consensus has been that economic mining of the ocean depths might be decades away.

but instead used a S-shaped vertical descent profile ( starting with an initially steep descent, followed by a leveling out, followed by a slight climb, followed by a return to a positive rate of descent continuing to splash-down in the ocean ) through Earth's atmosphere to reduce its speed until the parachute system could be deployed enabling a safe landing.

The goal, according to the Libyan press, would be to assemble an army of one million men and women fighters to prepare for the great Arab battle – “ the battle of liberating Palestine, of toppling the reactionary regimes, of annihilating the borders, gates, and barriers between the countries of the Arab homeland, and of creating the single Arab Jamahiriya from the ocean to the gulf ”.
