Earlier this 12 months, an infinite iceberg spanning round 209 sq. miles (510 sq. kilometres) calved from the George VI Ice Shelf, a floating glacier hooked up to the Antarctic Peninsula ice sheet.
The occasion introduced a novel alternative for deep-sea researchers on board Schmidt Ocean Institute’s R/V Falkor (too) to discover an enormous space of ocean that had by no means been accessible to people.
The staff reached the newly uncovered seafloor on 25 January, and with the help of their remotely operated car (ROV SuBastian) they started to research.
“We didn’t anticipate finding such a gorgeous, thriving ecosystem,” says expedition co-chief scientist Dr. Patricia Esquete.
“Primarily based on the scale of the animals, the communities we noticed have been there for many years, perhaps even a whole lot of years.”
The researchers made quite a few astonishing discoveries beneath the iceberg, together with icefish, octopuses and big sea spiders. Additionally they recorded the first-ever footage of a glacial glass squid.
However one of the crucial hanging animals filmed on the eight-day expedition was a large phantom jelly (Stygiomedusa gigantea). This mauve-coloured jellyfish can develop to a colossal measurement: the bell might be multiple metre (3.3 toes) throughout, and the animal’s 4 ribbon-like ‘oral arms’ can attain lengths of greater than 10 metres (33 toes).
The enormous phantom jelly is a uncommon and mysterious deep-sea jellyfish recognized for its ghostly, translucent look. In contrast to most jellyfish, it lacks tentacles and makes use of its arms to seize prey.
First collected in 1899, it wasn’t recognised as a species till 60 years later. It has been seen fewer than 150 instances by researchers, largely by way of deep-sea submersibles similar to Schmidt Ocean Institute’s ROV SuBastian.
