deep sea- Deep Sea secret

The video begins with an introduction of hydro thermal vent which states that “in many areas of high volcanic activity, water seeps into the sub-surface where it is intensely heated and then finds way to the surface again”.

It is further stated in the video that “in the ocean, this circulation occurs most commonly at the mid-ocean ridge, the world’s longest mountain chain.” It is also stated that “here, far below the depth of sunlight penetration, hydro thermal vents at over 400c with their dissolved compounds provide the basic for complex ecosystems.

The video was divided into three main categories: Mid-Atlantic Ridge, East China, and Bismarck Sea.

Mid-Atlantic Ridge

In the Mid-Atlantic Ridge, the deep sea horse mussels at a hydro-thermal vent water depth is 850m, also deep sea crab water depth is 850m. Hydro-thermal vent water depth is 860m and shrimp water depth is 855m.

East China Sea

The hydro thermal vent water depth is 1,480m and squat lobsters’ water depth is 1,500m. In this category, hydro-thermal vent water depth is also 1,500m.

Bismarck Sea

This category consists of white smoker water depth is 1,250m, shrimp at a hydro thermal vent water depth is 1,180 and squat lobsters water depth 1,220m. The black smoker water depth is 1,700-1,780m and shrimp at a black water depth is 1,720m.

The video closed with biotic community at a black smoker water depth is 1,720 and emission of liquid sulfur and bubbles water depth is 1,250m. There was lot of evaporation from the deep sea deep secret.
