Walruses can't stay indefinitely in the water like seals and similar mammals, so need somewhere to rest. Usually this is on ice, but the ice has apparently receded past the continental shelf so it's over deeper water. As the Walruses dive to feed off crustaceans and other tidbits on the seafloor, their larder is beyond reach if they stayed on the ice. Putting all this together, they had to find somewhere else to rest which just so happens to be here.
And just in case you wondered, they live in large groups anyway - it's not like roaming walruses decided to all congregate at once in this spot.
