Inside the pods are ten to fifteen seeds, each of which have a diameter of 6 cm (2.4 in) and a thickness of 2 cm (0.79 in). [6] The seeds contain a hollow cavity, which gives them buoyancy. After being washed by rain into rivers and then the ocean, the seeds of E. gigas drift long distances on ocean currents. Seed buoyancy and vitality lasts at ...
Ocean temperature and motion fields can be separated into three distinct layers: mixed (surface) layer, upper ocean (above the thermocline), and deep ocean. Ocean currents are measured in units of sverdrup (Sv) , where 1 Sv is equivalent to a volume flow rate of 1,000,000 m 3 (35,000,000 cu ft) per second.
In video games using procedural world generation, the map seed is a (relatively) short number or text string which is used to procedurally create the game world ("map"). "). This means that while the seed-unique generated map may be many megabytes in size (often generated incrementally and virtually unlimited in potential size), it is possible to reset to the unmodified map, or the unmodified ...
Deep-sea wood is the term for wood which sinks to the ocean floor. These wood-falls develop deep sea ecosystems. Deep-sea wood supports unique forms of deep sea community life including chemo-synthetic bacteria. Sources of carbon for these deep sea ecosystems are not limited to sunken wood, but also include kelp and the remains of whales. Much ...
Drift seeds (also sea beans) and drift fruits are seeds and fruits adapted for long-distance dispersal by water. Most are produced by tropical trees, and they can be found on distant beaches after drifting thousands of miles through ocean currents .
Because of the brine's high density and lack of mixing currents in the deep ocean, brine pools often become anoxic and deadly to respiring organisms. [7] Brine pools supporting chemosynthetic activity , however, form life on the pool's shores where bacteria and their symbionts grow near the highest concentrations of nutrient release. [ 8 ]
The project aims to identify and pool all Bathymetry data in the Southern Ocean and use that data to produce gridded bathymetric maps of the seafloor. The extent of the project is bound by 50°S, stretching from the southern tip of South America to the coastal waters of Antarctica .
With positive buoyancy (e.g. floating fruit), ocean surface currents freely move propagules, and dispersal distances are only limited by the viability time of the fruit, [55] [56] leading to exceptionally long single dispersal events (more than 100 km), [57] which is rare for passive abiotic movement of terrestrial fruit and seeds.
