Abstract
<p>Results of a cetacean sighting survey in coastal Gabon waters from September 4 to 9, 2011 are reported. Four whale species humpback (30 schools/191 individuals), Bryde’s (1 school/2 individuals), sei (1 school/6 individuals), and sperm (2 schools/2 individuals), and 3 species of dolphin (pantropical spotted (1 school/150 individuals), Atlantic spotted (1 school/40 individuals) and bottlenose (1 school/25 individuals)) were observed over 232.1 nm of transect lines (26% of planned transects, covering 878.0 nm). Based on these survey data, using distance sampling methods, we estimate the density of humpback whales in this region to be 0.481 individuals/nm2 (CV=0.477).</p>
