![]() Managing the Complexity of Your Large-Scale Software Architecture and Design The ACE session provides a forum for software-intensive system experts, users, developers, and researchers to collaborate on and elucidate high-level recommendations for improving the representation, development, and analysis of software architectures. The Architecture-Centric Evolution (ACE) Working Group session is the fifth of a GSAW series to promote the central role of software architectures during the acquisition and development of software-intensive systems.

Shallow, short dive profiles combined with few foraging buzzes provide evidence that little spotted dolphin feeding behavior occurs during daytime hours. ![]() ![]() Both whistle frequency characteristics and dive statistics measured here were similar to previously reported values for spotted dolphins in Hawai‘i. Tagged animals spent the majority of time in the upper 10 m (76.9% ± 16.1%) of the water column. Mean dive depth and duration were 16 ± 9 m and 1.9 ± 1.0 min, respectively. Thirteen foraging buzzes were recorded across all tags. Whistles ranged in frequency from 9.7 ± 2.8 to 19.8 ± 4.2 kHz, had a mean duration of 0.7 ± 0.5 s and a mean of 1.2 ± 1.2 inflection points. Start, end, minimum, and maximum frequencies, number of inflection points and duration were measured from 746 whistles. For each tagged animal, the number of whistles, foraging buzzes, dive profiles, and dive statistics were calculated. This study characterizes daytime acoustic and dive behavior of pantropical spotted dolphins ( Stenella attenuata) in Hawai‘i using 14.58 h of data collected from five deployments of digital acoustic recording tags (DTAG3) in 2013.
