IBCAO_V3_500m_RR: DBM compiled with all multibeam, dense single beam and land data added at 500 x 500 m resolution in a final step using the remove-restore method. This DBM is recommended for analyses requiring the best possible resolution where data exists. Well surveyed areas are clearly distinguished in this grid, specifically if there are nearby areas with sparse data that appear smooth.

IBCAO_V3_500m_SM: DBM compiled with the land data added at 500 x 500 m resolution in a final step using the remove-restore method. This DBM portrays the seafloor with a general and smooth appearance. The smooth representation of the seafloor was achieved by applying a Cosine tapered filter over 6000 m (see gridding methods described in 4.0.). This DBM may be better suited for overview map making than the version described in a) due to its more homogenous and smooth appearance.Both versions
