Available in PDF, EPUB and Kindle. Book excerpt: Since November 1995, the U.S. Navy's Sound Surveillance System (SOSUS) and other hydrophone arrays were used to regularly sample the occurrence of whale sounds in four regions bordering the continental margins across the North Pacific. The numbers of whales heard calling varied with season and location for each species, blue whales (Balaenoptera musculus), fin whales (Balaenoptera physalus), and humpback whales (Megaptera novaeangliae). For blue whales, calling during the fall season averaged 5 whales per event, winter averaged 1.5 whales per event, spring averaged 1 whale, and summer averaged 1.5 whales. For fin whales the numbers of whales heard ('F' calls from individuals) during winter averaged 3 whales per event, spring and fall calling averaged 1.5 whales, and summer averaged 1 whale. The 'J' calling events, regardless of season, were judged to be from at least 6 fin whales. Humpback singing typically was from 3 whales. These number demonstrated seasonal variations in calling whales for each region.

Book excerpt: This seventh year of monitoring calling whales via SOSUS hydrophones has continued to provide good data on the seasonal distribution blue, fin and humpback whales across the North Pacific. These data have allowed assessment of annual movements, environmental variability, and changes in call features. These data demonstrate (1) the occurrence and movements of calling components of the populations of these species in the offshore waters across the North Pacific, (2) the changes in these calls, (3) the estimated numbers of calling whales, (3) the correlation of calling with known features of population activities, (4) the annual patterns of offshore whale calling, and (5) tracks for individual whales. These have allowed good forecasts for the occurrence of these strong biological noises.

Available in PDF, EPUB and Kindle. Book excerpt: The seasonal distribution of calling blue whales (Balaenoptera musculus) and fin whales (B. physalus), and singing humpback whales (Megaptera novaeangliae) has been analyzed from acoustic data recorded by U.S. Navy Sound Surveillance System (SOSUS) and other hydrophone arrays in the North Pacific. The data from ten arrays were selected as representative of four Regions along the continental margins, labeled Northwest (NW), Northcentral (NC), Northeast (NE), and Southeast (SE). The call data indicate that there is a substantial population of blue whales scattered over the North Pacific and concentrated during the Fall season in the NW and NC Regions. Blue whale calls are recorded in all seasons, particularly in these NW and NC Regions. Fin whales are found in groups but also in relatively large numbers in all Regions, with most calling in the Winter season and in the NC Region, and calling is absent in most Regions during Summer. Fin whale calling includes "F" calls from individuals heard in all seasons and "J" calls from too many whales to separate, particularly prominent in the winter reproductive season. Humpback singing is recorded most in the NC and SE Regions at the time of their Winter/Spring migration. The distribution of singing humpbacks changed in both the NC and SE Regions between the 1996-1997 and 1998-2000 periods.

Book excerpt: Calls of blue whales (Balaenoptera musculus), fin whales (Balaenoptera physalus), and humpback whales (Megaptera novaeangliae) were identified in the data from U.S. Navy Sound Surveilance System (SOSUS) and other hydrophone arrays. These data on calling whales from November 1995 through July 1999 have been listed here for four offshore, deep-water Regions along continental margins of the North and Northeast Pacific. The occurrence of calling whales was monitored during two-day periods each week. Call data recorded from each array identified species, call occurrence, variation, received beam, and relative numbers of calling whales. This allowed assessment of seasonal distribution of calls for the different species, and provided locations for sources received at multiple arrays. Blue whale tonal sounds were distributed widely, received most in the NW Region, with a peak in occurrence in the fall. Fin whale "20-Hz" repetitive pulse sequences were received from whales grouped in local areas in all Regions, with a peak in occurrence in midwinter. Humpback songs were received from December through May particularly in the SE Region. The offshore listening systems allowed basin-wide monitoring of the seasonal distribution of these callng whales.

Book excerpt: A captivating exploration of how underwater animals tap into sound to survive, and a clarion call for humans to address the ways we invade these critical soundscapes—from an award-winning science writer “Sing Like Fish is that rare book that makes you see the world differently.”—Mark Kurlansky, New York Times bestselling author of Salt and Cod For centuries, humans ignored sound in the “silent world” of the ocean, assuming that what we couldn’t perceive, didn’t exist. But we couldn’t have been more wrong. Marine scientists now have the technology to record and study the complex interplay of the myriad sounds in the sea. Finally, we can trace how sounds travel with the currents, bounce from the seafloor and surface, bend with the temperature and even saltiness; how sounds help marine life survive; and how human noise can transform entire marine ecosystems. In Sing Like Fish, award-winning science journalist Amorina Kingdon synthesizes historical discoveries with the latest scientific research in a clear and compelling portrait of this sonic undersea world. From plainfin midshipman fish, whose swim-bladder drumming is loud enough to keep houseboat-dwellers awake, to the syntax of whalesong; from the deafening crackle of snapping shrimp, to the seismic resonance of underwater earthquakes and volcanoes; sound plays a vital role in feeding, mating, parenting, navigating, and warning—even in animals that we never suspected of acoustic ability. Meanwhile, we jump in our motorboats and cruise ships, oblivious to the impact below us. Our lifestyle is fueled by oil in growling tankers and furnished by goods that travel in massive container ships. Our seas echo with human-made sound, but we are just learning of the repercussions of anthropogenic noise on the marine world’s delicate acoustic ecosystems—masking mating calls, chasing animals from their food, and even wounding creatures, from plankton to lobsters. With intimate and artful prose, Sing Like Fish tells a uniquely complete story of ocean animals’ submerged sounds, envisions a quieter future, and offers a profound new understanding of the world below the surface.

Book excerpt: This title brings to light the discoveries and insights into the lives of many marine species made possible over the last decade by passive acoustic recorders (PAR). Pop-ups, ARF, HARP, EAR, Bprobe, C-POD Atag, and Dtag are the acronyms of some of the many PARs that have changed our understanding of how marine animals live and strive in the ocean. Various types of PARs are used by different investigators in different areas of the world. These recorders have accumulated copious amounts of very important data, unveiling previously unknown information about large marine animals. Temporal, seasonal and spatial distribution patterns have been uncovered for many marine species. There have been many discoveries, new understandings and insights into how these animals live in and utilize the ocean and the importance of acoustics in their lives. Listening Within the Ocean summarizes these important discoveries, providing both a valuable resource for researchers and enjoyable reading for non-professionals interested in marine life.

Available in PDF, EPUB and Kindle. Book excerpt: Every coordination within or between animals depends on communication processes. Although the signaling molecules, vocal and tactile signs, gestures and its combinations differ throughout all species according their evolutionary origins and variety of adaptation processes, certain levels of biocommunication can be found in all animal species: (a) Abiotic environmental indices such as temperature, light, water, etc. that affect the local ecosphere of an organism and are sensed, interpreted. (b) Trans-specific communication with non-related organisms. (c) Species-specific communication between same or related species. (d) Intraorganismic communication, i.e., sign-mediated coordination within the body of the organism. This book gives an overview of the manifold levels of animal communication exemplified by a variety of species and thereby broadens the understanding of these organisms.
