A new technique based on mini-UAS for estimating water and bottom radiance contributions in optically shallow waters [PDF]
, 2015 The mapping of nearshore bathymetry based on spaceborne radiometers is commonly used for QC ocean colour products in littoral waters. However, the accuracy of these estimates is relatively poor with respect to those derived from Lidar systems due in part

Use of Photogrammetry for Non-Disturbance Underwater Survey [PDF]
Advances in Archaeological Practice, 2016 AbstractStone anchors comprise a significant portion of observable underwater cultural heritage in the Mediterranean and provide evidence for trade networks as early as the Bronze Age. Full documentation of these anchors, however, often requires their removal from their underwater environment, especially to calculate mass.
