Macrofaunal diversity and abundance characteristics of sediment push cores collected by HOV Alvin during R/V Atlantis cruise AT37-13 and AT42-03 in the Pacific margin of Costa Rica from May to June 2017, and October to November 2018 respectively.
Sampling of sediment macrofauna took place on the Pacific margin of Costa Rica aboard the RV Atlantis using the submersible Alvin over May-June 2017 (AT37-13) and October-November 2018 (AT42-03), covering a depth range of 377-1908 m. Push cores were used to collect sediment samples from five methane seep sites (Jaco Scar, Mound 12, Mound 11, Parrita Seep, and Quepos Landslide) and surrounding non-seep sites. Samples were obtained under license of a collecting permit issued by the Ministerio de Ambiente y Energía of Costa Rica.
In total, 76 cores (6.4 cm internal diameter, 10 cm depth) representing 38 distinct sampling points (two cores per sampling point) were collected and analysed.
