A dataset of sampled and simulated benthic invertebrate body-mass data from the Porcupine Abyssal Plain Sustained Observatory (4850 m, 48.83° N 16.50 °W, NE Atlantic) has been produced. It includes data on macro- and megabenthos derived from a randomly sampled power law distribution, seabed core samples, large-scale seabed photography, and seabed trawls.

These data were compiled in connection with a manuscript (Ruhl et al. "Integrating ocean observations across body-size classes to deliver benthic invertebrate abundance and distribution information") submitted to the journal Limnology and Oceanography Letters, specifically to generate Figure 1 in that article.
