Benthic Polychaeta (Annelida) from La Paz Bay and Southwestern Gulf of California

During the oceanographic expedition GC06-1, 8 stations were sampled using a Reineck box corer on soft bottoms from the continental shelf of La Paz Bay and the Southwestern Gulf of California. Samples were collected during the spring of 2006 at depths ranging from 46 to 208 m, and 56 species belonging to 39 genera and 22 families of Polychaeta (Annelida) were identified. Environmental data of depth (m), salinity (psu), temperature (°C), dissolved oxygen (ml/L) and, sand and mud percentages were also measurement at each station.
