Is there a real possibility that the Arctic vortex will collapse due to global warming and the melting of the Arctic Ocean sea-ice? If the possibility is real and it "dies" in the coming decades, ...
In my story, I have a small extended family of 30 to 40 individuals ranging in age from 0 to 50 who are on the run from Chinese and Japanese forces in 1400AD. No place in Asia is safe for them. By...
Many planets out there will be water worlds. Those generally come in two flavors: either the oceans are so deep that the water turns into high-pressure ices like ice-six, -seven, -ten and -eleven o...
Many alien worlds will most likely be water worlds. I was wondering what the deepest possible global ocean dept is where land is still possible. I think that volcanic islands will still have a chan...
I want to build a seastead in international waters that starts small. It has to be in the Atlantic, preferably in the northern hemisphere close to either the american or european continent. Due t...
Could a planet be hot enough that oceans could form at the poles, but would boil at the equator? And would oceans form at all on this planet?
So long ago, I asked on how to make Earth's oceans as brackish as Lyr's, one of the many worlds imagined by artist Chris Wayans. The only real answer I got was something that that world had alread...
In a world I want to make, sailors would travel at sea for many years, perhaps up to ten, on sail boats. Obviously, they'd normally be stricken by scurvy and such, but I was thinking of some kind o...
This is a another sequel to my Plutonian questions, but I've decided to take a break from them and focus on another part of the world. Basically, my version of Pluto has five continents, each a si...
I'm thinking about a device (in a story I'm writing) that could control ocean currents, and I'm wondering how it could be weaponized. For example, if an ocean current was suddenly stopped, what mig...
Allow me to present Lyr, one of a handful of worlds crafted by artist Chris Wayan: The one detail among a vast many that is important to this question is that its salinity is about 1.5%, roughly...
On my Conworld, the oceans are purple. This is mostly for aesthetic purposes and my current explanation is an abundance of cyanobacteria. I'm not sure that this explains it correctly, so what could...
I'm trying to explain a large continent-sized archipelago that doesn't run in any particular direction. As such, plate tectonics cannot possibly explain its existence. This is an Earth-like planet....
I'm trying to find a justification to the sea level on Earth decreasing by a large amount (in the range of 1000 / 2000 m). The change would begin during the Modern Era or in the future, and last l...
An un-treatable virus starts infecting and killing people. Societies are on the brink of collapse, and it is decided the best way to save the most amount of people is to move everyone who can fit i...
An Earth analog had been modified by an advanced species to have saltwater seas in an interconnected grid across the planet's surface. The planet has no true oceans and only the large grid network ...
I'm interested in creating some construct of a society in the Twilight and Midnight zones of the ocean. By what means could they mine, farm, and trade in what is suppose to be a more futuristic so...
Earth's deepest point, the Challenger Deep, is almost seven miles below sea level. By contrast, Europa is smaller than even Earth's moon, yet its oceans are anywhere between 40-100 miles deep! So t...
What is the largest planet I can get, while still remaining within Earth-like parameters? My concern is with gravity, water pressure and atmospheric pressure. Escape velocity is less of a concern. ...
So, I am writing a comic which will perhaps grow into an entire series about a group of aquatic heroes. One of those heroes is a monster size aquatic lizard. The story of how this lizard came about...
I have a moon covered in liquid water that orbits a super-Earth very closely. As you might imagine, the tides are incredibly strong on this moon. However, it is tidally locked and so does not exper...
I'm running a D&D campaign and am using a modified map of Venus for it that shows what Venus would look like with similar amounts of water to Earth. The problem I'm running into is mapping the ...
Suppose, that in a particular area of the ocean on an earth-like planet, all water molecules are transmuted into an exotic variety of $H_2O$ that is identical to normal water in every way except wi...
On a habitable world completely covered in water, with no land above sea-level, there would presumably be storms of biblical proportions. Suppose this world has oceans so deep that the deeper layer...
I'm working on yet another iteration of a world map project. I'd like to ask for some opinions on the sea temperature map I've done: I also have a few specific questions about some areas on the...
What factors would influence ecosystem development in an ocean on an ice world? It is thought that several moons in our solar system (e.g. Europa) may have significant oceans under their icy crust...
I am building a world that has a single giant continent and nine island chains around the equator. I watched Artifexian's video on ocean currents and made a basic map, but it has no information re...
My idea is a device that gives its user great power over the ocean, its currents, and presumably temperatures. Could this be used to dramatically (and in relatively short time) effect the climate o...
So, in my story, in a prelude to an epic aquatic fight scene, my main character gets chased by a great white shark. He swims as fast as he can but he can't escape. Just to clarify, he's wearing one...
In my world, there is a chain of offshore volcanoes which are the result of a smaller plate hitting a larger one. There are two to three active volcanoes. My question is: two of these volcanoes a...
A habitable (human could survive in its atmosphere without suits) desert planet which used to have large oceans is quite common in ScFi. I was thinking about the processes which could have been res...
This series will focus on a Worldkillers: a group of interstellar outlaws who specialize in destroying worlds. Each question has the objective to explore a different way to kill a planet - a word...
In my universe, there are two ocean-based planets floating in space. I would like to merge them together in a realistic way. What kind of event could cause the planets to merge into a bigger one? (...
I have several types of free-floating vegetation to pick from: Trees Reeds/grasses Lily Pad like-plants Which type would best survive in the open ocean supporting small pockets of creatures, si...
I've been working on a constructed world which started out as the home of an alien race from a sci-fi story I'm writing but just became a pure world building project. As you can see from the map i...
Plastic is a huge problem in our lives. One of the ideas is to engineer plastic eating bacteria or fungi. Experiments already begun, and accidents already happen: a team of international scient...
I am building a world that is mostly land but i need something to divide it all up a bit so i decided I'm adding an ocean. What i want to know is the following: Would it be even remotely possible...
Let's assume that this hypothetical alien crawled out of the identical primordial ooze to the point where they share significant genetic similarity with humans, and due to either evolution or outsi...
In my book series, a space station called the T-Ray that is capable of causing explosions the size of the Chixculub impact explosion just fired at a planet that is completely covered by a massive o...
In my book series, a group of a few hundred explorers are sent from a planet called Ishgabangaloodoo to explore Sea World. Some things to know about Ishgabangaloodoo: Its citizens are referred t...
How do you go about building a working Earth-like ocean ecosystem from scratch in Europa's subsurface ocean? On Earth, abyssopelagic species have evolved to live more than 6km below the surface. A...
In the world I'm building, there is a single continent. However, in the deeper parts of the ocean, there are hydrothermal vents. They're pretty necessary to my story, but I can't figure out why the...
This is the first of possibly several posts about the following scenario, in which Earth's sea-level rises 2 km overnight, generating a world map looking like this: Question: What would be the c...
The Bay of Fundy sees the world's highest tides, with ocean water advancing and withdrawing as much as 20 meters or more within a single day. Here is a list of the 50 tidal stations around the wo...
So I'm writing a book and need help to better explain this island that sinks, more on that in a moment as I give you the basic build of the planet... First, its a world on a very tilted angle. the...
Suppose we've colonized a planet with 99% of the surface area covered by oceans. It has submerged continental crusts, averaging 200-500m underwater, with the average depth of open ocean being 1000-...
What marine or brackish water animals would be best for domestication attempts by a semi-aquatic civilization? Bonus Points for those that get me pet/domesticated sharks!
I have a type of coral that feeds off of bacteria that love bird feces (or something involving a bird species). It grows large rocky spires out of the water to create a habitat for birds. I need to...
I'm writing a short story that takes place on an imaginary planet that is 88% ocean. The planet has two moons and one continent that is regularly flooded under 500 to 1500 feet of water. The tides ...
Piggybacking on this question: Could soft matter infused with nano or pico sized magnets be used to clump together so that we could create environments with it? ...So we have a planet that has low...
