Abstract/Contents

Abstract: Understanding what physical parameters of the ocean effect pteropod abundance and distribution has yet to be studied and is of paramount importance to the scientific community. Pteropod communities were quantified from 15º South to 15º North in the equatorial Pacific Ocean, and then compared to oceanographic parameters at those same latitudes. Temperature, oxygen concentration, water density and salinity were all analyzed, and found to trend with pteropod density. In particular, low oxygen concentrations correlated with low pteropod densities, and denser water correlated with pteropods contributing to less of the overall zooplankton abundance. These trends suggest that competition is the main driver in pteropod abundance and distribution across the Pacific Ocean, although such effects of competition are likely due to physiological adaptations of the pteropods. Further study, particularly in the field of pteropod respirometry, is needed to establish and interpret such preliminary trends.
