プロジェクトデータ

A novel collaboration between commercial submersible pilots, and their organizations, with Southern Benthics to provide footage of the seabed around Antarctica for the purposes of securing protection for VMEs, and for monitoring the health of those VMEs in the long term in the face of the climate crisis.

収集方法

Sampling was conducted by U Boat Worx Cruise Sub-7, recording imagery with Panasonic AW-UE150KEJ 4K Integrated PTZ camera operated with a Panasonic AW-RP60GJ remote camera controller.

Method step description:

1. DaVinci Resolve 18 was used to combine separate files where necessary and for editing.
2. Clean-up followed the same methodology as was used for analyzing the submarine footage for the successful nomination of VMEs in WG-EMM-22/46Rev1 to remove unusable sequences. For the Lambda Is footage that meant the removal of any sequences where the submersible was too far from the wall, where the visibility was poor and when the submersible was stationary. Footage from Dive A was the longest resulting video after the completion of this clean-up procedure (Table 1), thus it became the footage that was analysed.
3. Footage was color adjusted within DaVinci Resolve 18.
4. The analysis methodology also followed that which was used in WG-EMM-22/46Rev1. To compare the relative percent abundance of VME indicator taxa to that of non-VME taxa and bare substrate at the Lambda Is site, frames were exported at regular intervals (30 secs) beginning at 0:00.
5. The resulting series of images were then imported into the program PAPARA(ZZ)I (Marcon & Purser, 2017). Within this program images were further enhanced by adjusting brightness, contrast and gamma. As recommended by the authors, the usable area was then defined for each image allowing the exclusion of dark or blurred edges.
6. Once images were prepared in this way, an array of 100 random points was overlayed. Each point in each image was assigned one of three designations: VME indicator taxa, non-VME taxa or bare substrate.
