A biome with a salinity of 0.005 would likely be a freshwater biome, such as a river, lake, or stream. This low salinity level indicates a lack of significant dissolved salts or minerals commonly found in saltwater environments.

The different aquatic biomes are determined by factors such as depth, salinity, water flow, and temperature. These factors influence the type of organisms that can live in each biome and shape the overall ecosystem dynamics.
Salinity refers to the concentration of salt in water. Salinity typically increases with depth in oceans due to the processes of evaporation and freezing which leave behind salt in the water, as well as the mixing of water masses within the ocean.
The average ocean salinity is around 3.5%. It is typically measured in parts per thousand (ppt) or in PSU (practical salinity units), with most oceans having a salinity close to this average value.
Salinity is the saltiness or dissolved salt content of a body of water. Salinity in Australian English and North American English may also refer to the salt in soil.
Antarctica has a polar desert biome, ice biome, tundra biome, rocky biome, and coastal biome. These biomes support a variety of unique plant and animal species adapted to survive in extreme cold temperatures and harsh conditions.
