Aerial-photo and LiDAR iceberg surveys during the 2015 Joint Statoil/ArcticNet Cruise, Newfoundland and Labrador, Canada

Triplicate aerial-photo and LiDAR surveys of two iceberg sails were conducted to evaluate the capability of each technique to detect iceberg or ice island deterioration. This evaluation lays out how the spatial pattern and rate of iceberg deterioration could be measured with repeat surveys. 3D representations of the iceberg sails were generated from the aerial-photo surveys with the structure-from-motion (SfM) processing method as well as directly from the LiDAR data. The SfM data was scaled using GPS markers deployed on the icebergs prior to surveying and these were also used to correct the LiDAR data for iceberg drift. Scripts which were written for drift correction are included with the data. Alternative drift correction workflows can be developed and tested with the uncorrected data. The GPS data, some of which extends after the surveying was complete, can be utilized for drift analyses and drift model improvement. The dataset contains: image files from aerial-photo surveys (.nef and .tif), LiDAR point clouds (.txt files with lat/lon/elevation/timestamp) pre-and post-drift correction, INS (inertial navigation system) data (.txt files), GPS tracks (.csv files with lat/lon/elevation/timestamp), GPS error and PPP (Precise Point Positioning) output (.csv files), and point cloud scaling information. This data was collected during a collaboration between Statoil ASA and ArcticNet which ran during Leg 1 of the 2015 research cruise on board the CCGS Amundsen.

Purpose: This dataset contains repetitive aerial-photo and LiDAR surveys of iceberg sails. The intention behind collecting and providing this data to others is to assess and further develop techniques for the observation of iceberg and ice island deterioration. In the future, these techniques can be applied to the improvement of predictive iceberg drift and deterioration models. The data can also be used for drift analysis and modeling efforts. The deterioration detection analysis is included in the article: Crawford, A.J., Mueller, D.R., Joyal, G.
