Marine Vegetation to Change Antarctica's Ecosystem
Until now, Antarctica's delicate marine ecosystem was thought to be protected by the giant and fierce ocean surrounding it.

But an international study led by the ANU has found aquatic vegetation is capable of crossing the Antarctic Polar Front carrying crustaceans, worms, snails and other sea weeds.

Antarctica is protected by strict guidelines restricting visitors from bringing in foreign marine life to prevent the local ecosystem from being destroyed.

Rules in place prohibit ships emptying ballast tanks in surrounding water and scientists are not allowed to take larvae of marine animals in there.

However evidence collected on three separate ship voyages in 2008, 2013 and 2014 shows marine plants and animals can easily get into Antarctic waters on their own.
