Biodiversity patterns of epipelagic copepods in the South Pacific Ocean: Strengths and limitations of current data bases

Fig 2. Richness patterns of Copepoda in the 0–200 m layer of the western and eastern side of the SPO for the period 1993–2019 based on species occurrence data obtained from OBIS portal. (a) Spatial distribution of alpha diversity considering the complete data cell with the curated data (i.e., 377 cells). (b) Inverse distance weighted (IDW) analysis for alpha diversity using cells with >10 species (i.e., only 77 cells from the total of 377 were selected). (c) Kriging interpolation for alpha diversity using cells with >10 species (i.e., only 77 cells from the total of 377 were selected).
