Helen 2014-12 (Expedition) - Helen (Island) - Raw Images. In 100 Island Challenge Collection

In December of 2014, the 100 Island Challenge team visited Helen to collect large-area imagery as part of the Helen 2014-12 expedition. The imagery collected here established permanent sites that can later be resurveyed as part of the 100 Island Challenge Project. For each site, a preview image and the raw digital images used to create composite large-area image products of the underwater sites have been made available. A general description of the methods used to acquire the images can be found in a README.txt file for each site. Site specific metadata can be found within a METADATA.txt file for each site.
