Minecraft wiki entry for Ocean, associated text: The frozen ocean has dark purple water at the surface and generates when an ocean is in a region with snowy biomes, and often borders snowy beaches. Like the standard and cold oceans, it has a gravel seabed, though the water's surface is mostly frozen. Neither seagrass nor kelp generates on the seafloor, leaving it entirely barren and reminiscent of pre-Update Aquatic oceans. Large icebergs made of snow blocks, packed ice and a bit of blue ice frequently generate on the surface, where rabbits,‌[Bedrock Edition only] polar bears and strays may spawn. Salmon, cod‌[Bedrock Edition only] and squid may spawn here as well and are the only aquatic mobs (other than drowned) that can.
