Panama Canal: Challenge of connecting two oceans of different levels.
But the Pacific Ocean is very different from the Atlantic, so offspring with like a killer whale, they can wipe out all the mid-level predators. Because it has to overcome a height difference. The ground is higher than sea level at the middle of the canal. So instead of digging the canal. Photos dubbed the place where two oceans meet have been making the rounds on the Internet for years, but there's a lot of misinformation out.
When animals from the Pacific meet their counterparts on the Atlantic, they're usually similar, which means they can mate. But the Pacific Ocean is very different from the Atlantic, so offspring with foreign parents might be born without the physical adaptations needed to survive.
The white northern gannet from the North Atlantic is spotted off the coast of San Francisco interacting with the native Brandt's cormorants. Eva Gruber Animals traveling through the Northwest Passage may also carry diseases.
If the Atlantic and Pacific Oceans are at sea level, why are locks needed in the Panama Canal?
For example, some of the seabirds on the East coast carry Lyme disease, a condition that's transferred to humans via ticks. Predators moving from ocean to ocean can also create big problems. When you add a new top-level predator to an ecosystem, like a killer whale, they can wipe out all the mid-level predators.
This has a waterfall effect and can completely restructure the food web, O'Malley says.
If Atlantic and Pacific Sea Worlds Collide, Does That Spell Catastrophe?
The melting sea ice also has some serious environmental policy implications, Oleson says. As animal populations move from ocean to ocean, they cross into international waters, which makes them more difficult to monitor and protect. Steven Rottenborn The Northwest Passage isn't the first case of an open passageway between two bodies of water. There in the gulf, the two types of water run into each other, a light, almost electric blue merging with a darker slate-blue.
Informally dubbed "the place where two oceans meet," the explanation for the photo is a simple one, though there are many misconceptions about it, including that catchy title. In particular on popular link-sharing website Reddit, where users have on multiple occasions erroneously attributed the photo's location as " Where the Baltic and North Sea meet " and the two types of water as being completely incapable of ever mixing, instead perpetually butting against each other like a boundary on a map.
You also may have seen a variation on the photo featuring the same phenomenon, taken by photographer Kent Smith while on a July cruise in the Gulf of Alaska.

That photo too has been circulating the web for some time, though the misconceptions about it seem to be less thanks to Smith's explanation of the photo on his Flickr page. That one has also been making the rounds on Reddit and social media for years, and had racked up more thanviews by early on that one page alone, Smith said. That original photo, however, originates from a research cruise of oceanographers studying the role that iron plays in the Gulf of Alaska, and how that iron reaches certain areas in the northern Pacific.
In fact, he was the one who snapped the pic. He said the purpose of the cruise was to examine how huge eddies -- slow moving currents -- ranging into the hundreds of kilometers in diameter, swirl out from the Alaska coast into the Gulf of Alaska. Those eddies often carry with them huge quantities of glacial sediment thanks to rivers like Alaska's mile-long Copper River, prized for its salmon and originating from the Copper Glacier far inland.
It empties out east of Prince William Sound, carrying with it all that heavy clay and sediment.
