The data represent the megabenthic invertebrate biodiversity as a result of an environmental monitoring program for assessing the biological component of the sedimentary matrix that could be affected by the exploratory process of the Perla 1X well located in the northwest coast of the Paraguana Peninsula, within the Golfo de Venezuela region.Sampling Description
Study Extent
Golfo de VenezuelaSampling
To carry out the analysis of the benthic community present, sediment samples were collected using a “Box Core” type dredge (area 0.19 m2) at each of the stations selected according to the proposed sampling design. From the sediment sample extracted with the "Box Core", two cylinders of 0.0038 m2 area were taken, whose content was poured into a duly labeled plastic bag and preserved with 10% formalin. Three replicates were taken for each station (samples from two independent hauls) and all samples were transferred to the Bentos Marino laboratory of the Simón Bolívar University.Method steps
