Abstract:
Mesopelagic acoustic scattering layers at a 700 m deep location in the Red Sea ascended 70 to 80 m during a passing rain storm that reduced light levels at the surface by more than 2 orders of magnitude. The changes in vertical distribution were observed down to the deepest part of the water column and were interpreted as a response to sudden dark weather. However, light measurements suggest that the mesopelagic targets (fish) did not fully compensate for the reduction in ambient light, and the calculated light levels in the scattering layers were similar to 1 order of magnitude lower during the passage of the storm. The results show that fluctuating weather conditions may affect pelagic ecosystems even towards the lower parts of the mesopelagic zone.
