One of the objectives of the EXPRESS cruise is to collect quantitative information about the seafloor communities in the areas we are studying. To characterize these communities as accurately as possible, our surveys must be standardized to avoid bias, and conducted multiple times to capture variation. This means that we need to measure the area we are surveying, and within that area, identify the animals that we see, count them, and estimate their size. We also need to identify and measure the types and amount of seafloor habitats within the survey area. How is this done with the remotely operated vehicle?
