Odontocete detections are linked to oceanographic conditions in the Hawaiian Archipelago by Morgan A. Ziegenhorn, John A. Hildebrand, Erin M. Oleson, Robin W. Baird, Simone Baumann-Pickering

“…Here we make use of long-term passive acoustic monitoring data to examine relationships between eight classes of toothed whales and climate indices, specifically El Niño Southern Oscillation, Pacific Decadal Oscillation, and North Pacific Gyre Oscillation, as well as local surface conditions (temperature, salinity, sea surface height) at two sites in the Hawaiian Archipelago. …”

Limited trophic partitioning among sympatric delphinids off a tropical oceanic atoll. by Hillary Young, Katherine Nigro, Douglas J McCauley, Lisa T Ballance, Erin M Oleson, Simone Baumann-Pickering

“…In this study, we used stable isotope analysis of skin biopsies to compare the isotopic, and thus, trophic niches of three sympatric delphinids in the waters surrounding Palmyra Atoll, in the Central Tropical Pacific: the melon-headed whale (Peponocephala electra), Gray's spinner dolphin (Stenella longirostris longirostris), and the common bottlenose dolphin (Tursiops truncatus). δ15N values suggested that T. truncatus occupied a significantly higher trophic position than the other two species. δ13C values did not significantly differ between the three delphinds, potentially indicating no spatial partitioning in depth or distance from shore in foraging among species. …”
