An increase in the use of geomorphometry in the
marine environment has occurred in the last decade. This has
been fueled by a dramatic increase in digital bathymetric data,
which have become widely available as digital terrain models
(DTM) at a variety of spatial resolutions. Despite many
similarities, the nature of the input DTM is slightly different than
terrestrial DTM. This gives rise to different sources of
uncertainties in bathymetric data from various sources that will
have particular implications for geomorphometric analysis. With
this contribution, we aim to raise awareness of applications and
challenges of marine geomorphometry.peer-reviewe
