Underwater logging

When artificial reservoirs and dams are built, large areas of forest are often inundated; although the trees die, the wood is often preserved.

This activity can be quite profitable, since the prime "targets" are decades-old trees of a size and species difficult or impossible to find in their natural habitat.

Rivers were a main method of transportation in the logging industry in the 19th and early 20th centuries in the United States.

In the spring, logs were floated down waterways, especially those surrounding the Great Lakes and Maine, to transport them to mills downriver.

Loggers attempted to reduce the number of logs which remained in the river in order to maximize profits, but some losses were inevitable.

Underwater logging uses new technology to cut down drowned trees that have been lost due to rising water levels or artificial reservoirs.

[4] This process repeats itself until the boat is filled to its capacity, after which the expedition is completed, and crew must return to base before harvesting any additional logs.

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.

Accidents related to this industry usually result in the release of oil and other resources, as these spills are difficult to maintain due to the fluidity of lakes and rivers.

What this means is that the potential for collateral damage is large, both for marine and human life, because toxic resources such as oil can contaminate surrounding ecosystems.

These logs provide substantial structural support for these ecosystems, and removing them would inevitably destroy said natural habitats.

This process was awarded for being sustainable by avoiding deforestation and making artificial reefs to maintain the current aquatic ecosystem.
