The unknown part of the Southern Ocean biodiversity was approached by pointing out what remains to be explored and described in terms of geographical locations and bathymetric zones, habitats, or size classes of organisms. The growing importance of cryptic species is stressed, as they are more and...
The resulting geo-dataset of seamounts offers an indication of the distribution of seamounts over the seafloor and shows that over 60% of seamounts occur in the Pacific Ocean. It was also determined that 50% of the seamounts occur within the exclusive economic zones (EEZs) of countries. ...

Long-term observations, which were collected in the Sea of Okhotsk coastal zone under open-water conditions and at times when the sea was ice-covered from
(291 kilometers) of rope to measure the depth of the ocean. During their four-year voyage, the Challenger crew collected samples of rocks, mud and animals from many different areas of the ocean. They also found one of the deepest zones, in the western Pacific, the Mariana Trench which ...
Overall the presence pseudo-absence sampling scheme results in twice as many absence as presence points and ensures that all Köppen zones are represented. Plant Type Assignment In this section, we describe how we assign species to plant types. This is done for all species for which we have ...
