This paper evaluates whether 1) protoplatyrrhines could have migrated to South America via Antarctica, and 2) the floating island model is a plausible transoceanic mode of dispersal for land vertebrates like protoplatyrrhines. Results show that Eocene Antarctica and Australia supported large and dense forests, and that the Antarctic fauna was comprised of many species of vertebrates, including placental and marsupial land mammals. However, no primate remains have ever been reported from these continents. Antarctica and South America were connected until the Middle Eocene (i.e., after the oldest Asian anthropoids), but two major water barriers existed between Antarctica and Asia since the Early Eocene. The Eocene and Oligocene water gap separating Africa and Antarctica was excessively large. Thus, all scenarios involving an Antarctic route have been rejected. The African scenario is difficult to falsify because only one water barrier existed, both paleowinds and paleocurrents were favorable, and Paleogene African anthropoids show phylogenetic affinities to platyrrhines. I tested whether a journey on a hypothetical floating island over the Paleogene Atlantic Ocean exceeds the survival limit of a genetically viable group of animals such as protoplatyrrhines. Studies of water deprivation suggest that they could have been able, with a body weight averaging 1 kg, to survive without water for at least 13 days. I have used the present Atlantic Ocean as a model for the velocity of Paleogene paleowinds and paleocurrents. Considering winds as the key accelerating force of floating islands, the Paleogene Atlantic water barrier could have been crossed, in the most conservative scenario, in 8 days at 50 Mya, 11 days at 40 Mya, and 15 days at 30 Mya. In order to survive a transoceanic journey, however, protoplatyrrhines had to be preadapted to strong seasonal variations in water availability in their original (African) environment. Once on the sea, their brains would have physiologically interpreted the rarity of water as the beginning of the dry season, and the group would have switched its diet to alternative foods, i.e., everything available on the floating island.
This would be really helpful to me as well.
I would also suggest adding a transparent mode toggle in edit mode. If you had the option to show a ghost image of the rest of the model below the support areas it could make it easier to identify unsupported areas.
I also believe this floating island behavior becomes more prominent when you reduce the point size of supports. It also seems that on symmetric models the algorithm will catch an island on one side of a model but not the other.
I would previously hollow models to save material but have mostly stopped because if I miss a floating island on a large part it will blow up a very long print. The automatic supports do not catch them and on large or complex models I can miss them too.
For inSITE97, Vito Acconci proposed to extend the existing US-Mexico border fence out into the Pacific Ocean by constructing a floating island that would move with the tides. Fabricated with sand and rocks atop a fiberglass structure, the island would have Umbrellas to provide shade and space for swimmers from either side of the border to rest. Envisioned to represent a liminal space, the island would allow people to escape the border's constraints on people's lives and movement, if only temporarily. Due to various obstacles, including permissions and construction costs, Island of the Fence/Isla en la muralla remains unrealized. --inSITE97
If you can't beat the sea, why not join it? That's the thinking for a team of Dutch engineers developing floating islands that might one day be a remedy for sea level rise in the Netherlands, south Louisiana and other low-lying areas.
"As sea levels rise, places like New Orleans may need space where they can develop or put homes. And these islands may be an answer for that," said Olaf Waals, project developer for the Maritime Research Institute Netherlands.
This month, Waals began testing a 26-foot-wide model of what might one day stretch across three miles of sea. "Our first test was to see how it behaves in wind, waves and current," he said. "It did well because the island flexes with the waves, and it even follows the curve of the ocean."
Waals said floating islands could be used as work sites in the Gulf of Mexico or support structures for the shipping industry. Located far offshore, the islands could be outfitted to capture wind, wave or tidal energy, or host arrays of solar panels. They might also be useful for cultivating food, such as fish or seaweed.
Moving at-risk coastal communities to floating islands might alleviate the need for more and larger river levee systems, which bear some of the blame for Louisiana's land loss. Levees prevent the natural spill and spread of sediment from the Mississippi River. Starved of sediment, land on the coast is disappearing at a fast rate due to erosion, subsidence, sea level rise and other factors.
"There are pros and cons to dikes and levees, and this is another option," Waals said. Among the cons: Floating islands block sunlight, potentially hampering the growth of aquatic plants. Other effects on the sea floor, fish and wildlife would have to be considered, he said.
It'll take a decade or two before floating islands move from model to reality. After more months of computer modeling and scale model tests in an ocean simulator, the project will move to materials research, which itself could take years. Delving into a bit of human psychology might also be in order.
Louisianans might warm to the idea more quickly than others. Already, the state's coastal fishing communities are losing people due to flood risk and land loss. Most of the tiny population of Isle de Jean Charles in Terrebonne Parish is expected to move to a relocation site 40 miles inland, for example. There, the island's fishers and shrimpers will lose a defining element of their community.

Sry its hard to describe in a other language xP
What I want is a Model which looks like a floating island(like in Avatar f.e.).
But because of Textures Store Problems I want to create a Terrain with terramonkey and do the part which you see when you look at the island from bottom with Blender. (so the floating island is in two parts)
When I got the Heightmap from the Terrain in Blender as a Model its easy to create the other part and then load it ingame at the same position. (my thought)
The reason no one answered, is because of the paradigm terrain modelling industry works in. All terrain modelling algorithms in circulation right now, work with "heightfield" data. Which means all terrain tools also work within this constraint. And THIS being a forum dedicated to a tool called Gaea, assumes that the question would be about Gaea, a terrain modelling tool that works with "height fields".
Technically, you can still use Gaea assets to make the floating islands. It takes a great amount of work to do, though, and proper projection to have the height (displacement) map wrap around a spherical object. In the end, it isn't worth the extra time to do it unless you have a fast workflow already down.
Nowadays, fears over rising sea levels due to global warming have prompted many countries with lands below sea level to find solutions to ensure the safety of nation and citizen. Furthermore, the development and utilization of marine resources have always been a topic of interest. Due to these necessities, the concept of flexible floating islands that can be used for fish farm, energy islands and residence has emerged. The flexible floating island consists of many smaller identical triangles connected by springs. This design is convenient for installation, disassembly, and diversification of functions. The main objective of this thesis is to investigate and analyze the forces acting on and motions of the flexible floating islands due to the interaction with regular waves; a numerical model is an excellent way to complete that mission. The floating islands in waves that are constrained with mooring lines have translational and rotational motions under the combined effect of hydrodynamic, hydrostatic, gravitational and mooring forces. The approach for solving the forces starts with linear potential theory, which means that uncompressed inviscid flow is assumed. After marking out the identical smaller panels on the wetted surfaces of each small triangle, the interface conditions between the triangle and the fluid are satisfied, thereby obtaining the source strength for each panel. With the expressions for the potentials, all the hydrodynamic coefficients including added mass, damping and wave exciting forces can be evaluated. Finally, the response of islands can be evaluated by using the equations of motions of the island in the time domain and converting them to the frequency domain. Two models are created in this thesis, a single island model and a two-island model, the former focuses on learning the methods for solving the hydromechanics coefficients, and the latter focuses on the hydrodynamic interaction between the two islands.
The island was bashed all together using 1 modular terrain piece that suited my needs, all 4 faces of it have different elements from the cliffs in the original concept. I figured the overall shape of the island after different iteration passes and feedback from Lincoln Hughes who also provided me with the Z-UP material I used for the grass!
A robust parametric model is presented that can generate different polygonal regular tilings or irregular networks of freeform, modular floating islands. The doubly curved geometry is possible by using Buoycrete, a neutrally buoyant, non-dissolvable concrete mix. This allows for floating bodies that are designed and optimized beyond what is traditionally possible with conventional construction. One output from the parametric model, a single module designed for North Sea conditions, is evaluated using diffraction and CFD analysis to inform the parametric model and to demonstrate the potential of our approach.
