To ensure confidentiality, we also filtered out data when it came from fewer than 3 vessels. The tables below include data from 1993 through 2005.

Table 1Number of sampled hauls per year and the percentage available to the public.
Table 2. Weight of the sampled hauls/sets and the percentage available to the public.
Table 3Number of mapped cells per year and the percentage available to the public.
