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 ...
A few Diospyros species, such as macassar and mun ebony, are dense enough to sink in water. Ebony is finely textured and has a mirror finish when polished, making it valuable as an ornamental wood. [1] It is often cited as one of the most expensive woods in the world.
Lignum vitae is hard and durable, and is also the densest wood traded (average dried density: ~79 lb/ft 3 or ~1,260 kg/m 3); [4] it will easily sink in water. On the Janka scale of hardness, which measures hardness of woods, lignum vitae ranks highest of the trade woods, with a Janka hardness of 4,390 lbf (compared with Olneya at 3,260 lbf, [5] African blackwood at 2,940 lbf, hickory at 1,820 ...
After this occurs and once the tubes are securely in place, a hookah compressor and a low-pressure hose re-inflates them so that they form a tight grip around the floating logs. This process gives the logs more buoyancy and gives loggers easier access points to harvest them. As many tubes that are needed are used to float the logs. [4]

Earthquakes can rattle large swathes of the country. Here's what causes the geologic phenomenon.
The Guinness Book of World Records lists this tree as the world's heaviest wood, with a specific gravity of 1.49, similar to that of anthracite or dry earth. [8] It is known for its tendency to sink in water, unlike other wood materials. It is also one of the world's hardest woods according to the Janka hardness test. The timber has a good ...
