Dataset: 2018 Galapagos Fish Survey: observations and temperature

SCUBA surveys were used to quantify the composition and diversity of fishes at five sites. We performed four 50x10x5 m (length, width, height) transects at each site (2 per dive, 1 per diver). This protocol was based on the ecological monitoring protocol used by the Charles Darwin Foundation and the Galapagos National Park. The diver swam along one side of the 50m long transect (the right side first, the left side second) and identified and recorded every fish present in a projected 5x5x5 m3 volume (width, height, depth forward). At the end, the diver surveyed the other side of the transect. The values for each side were included for each transect in the data, but they should not be considered independent. They could, however, be used as terms nested within transect. Values in each cell are the number of fish of each species observed.
