The impact of Antarctic sea change (Part 1)

It seems too late to discover the age of some events as well as phenomena. However, a recent discovery by the British research team after a trip to the south sea to explore the ship James Clark Ross opened a new beginning for the discovery.

Earlier this month, the steam-powered ship, Ross, was pleased to carry the expedition team of geologists, oceanographers, and biologists towards the southernmost region of the earth. About the next two weeks, scientists will model the shape and collection they discovered from the bottom of this sea, in addition to details of the hunt for sea turtles.

According to Sven Thatje, an ocean ecologist at Southampton University Hydrological Center, "the deep ocean is one of the areas where people are hard to know, and we are trying to strength to change this'.

The voyage of Ross ship in this polar sea is prepared and planned in great detail. Scientists on the ship are very eager to admire the magic of the deep ocean floor as well as discover the ephemeral population that has flourished very well since the last ice age nearly 20 thousand years ago. In addition, they are looking forward to finding traces of sea samsarians, fierce predators of the blue ocean.

It is hard to believe that arthropods migrate to this remote southern region because of the harsh conditions here. But if the trace of the sea sam is found, it will become a testament to the warming of the earth. Another purpose of the trip was that they expected to find more examples to analyze the adaptability of the organism to the harsh conditions of nature.

The remote detection device (ROV) called Isis will capture a series of images of reef ranges and the slope of the Antarctic peninsula. The scientists controlled the ROV through a transatlantic cable about 6.5 km long. In addition to capturing images, Isis also has a sound wave division to portray the shape of the seabed with 3D graphics. Isis consists of robot-like arms, a system of waste pumps to collect research samples and a collection of tubes about 50cm long to collect hard objects and advanced parts to collect samples.

The first week of the trip took place smoothly without any problems. Thatje stated in ScienceNow as follows: 'Luckily because of the stable climate conditions and the calmness of the ocean, we were able to observe and analyze a lot about this southern polar reef range. . The depth of 3.5km on January 26 is the record depth that ROV achieved in this sea. "

There has been no discovery of sea creatures, but scientists have found very interesting species, a crab crab is being kept for genetic research.

Geologists also have a reason to be excited. The ultrasound system of ROV has delicately illustrated the graph depicting the geological variation of the coast: fragments of rock must have been washed into the continent on icebergs, when the ice melted. flows leave them on land. The chart also shows that the underwater straits are kilometers wide and 'sedimentary rocks with a diameter of about a few million years ago, also slipped into this underground area' - according to Julian. Dowdeswell - director of Cambridge University. Stone samples found there are clear evidence of polar ice freezing in most studies of the history of geological development in this region.
