Cetacean Occurrence in the Gulf of Alaska from Long-Term Passive
Marine Biology (2021) 168:72 https://doi.org/10.1007/s00227-021-03884-1 ORIGINAL PAPER Cetacean occurrence in the Gulf of Alaska from long‑term passive acoustic monitoring Ally Rice1 · Ana Širović1,2 · Jennifer S. Trickey1 · Amanda J. Debich1,3 · Rachel S. Gottlieb1 · Sean M. Wiggins1 · John A. Hildebrand1 · Simone Baumann‑Pickering1 Received: 23 November 2020 / Accepted: 11 April 2021 © The Author(s) 2021 Abstract The Gulf of Alaska is an important habitat for a diverse array of marine mammals, many of which were severely depleted by historical whaling. To study current cetacean distributions in this region, passive acoustic monitoring was used to detect species-specifc call types between 2011 and 2015 at fve locations spanning the continental shelf, slope, and ofshore sea- mounts. Spatial and temporal detection patterns were examined for nine species to compare diferences in behavior and habitat use. Mysticetes showed seasonal increases in calling that indicated possible behavioral shifts between feeding and breeding in blue (Balaenoptera musculus), fn (B. physalus), and humpback (Megaptera novaeangliae) whales, and matched known migration timing of gray whales (Eschrichtius robustus). Interannual changes in blue and fn whale calling may relate to the marine heat wave that began in 2013 and lasted through the end of the monitoring period. Odontocete detections revealed unique spatial distributions, with killer whales (Orcinus orca) most common on the continental shelf and sperm whales (Physeter macrocephalus) most common on the continental slope, where detections occurred year-round. Beaked whales showed both spatial and temporal separation: Baird’s beaked whale (Berardius bairdii) detections were highest at Quinn Seamount in the spring, Cuvier’s (Ziphius cavirostris) at Pratt Seamount in winter, and Stejneger’s (Mesoplodon stejnegeri) on the continental slope in the fall.

Description of a New Species of Beaked Whale (Berardius) Found in the North Pacific
www.nature.com/scientificreports OPEN Description of a new species of beaked whale (Berardius) found in the North Pacifc Received: 30 November 2018 Tadasu K. Yamada1, Shino Kitamura2,3, Syuiti Abe3, Yuko Tajima1, Ayaka Matsuda3, Accepted: 4 July 2019 James G. Mead4 & Takashi F. Matsuishi3,5 Published: xx xx xxxx Two types of Berardius are recognised by local whalers in Hokkaido, Japan. The frst is the ordinary Baird’s beaked whale, B. bairdii, whereas the other is much smaller and entirely black. Previous molecular phylogenetic analyses revealed that the black type is one recognisable taxonomic unit within the Berardius clade but is distinct from the two known Berardius species. To determine the characteristics of the black type, we summarised external morphology and skull osteometric data obtained from four individuals, which included three individuals from Hokkaido and one additional individual from the United States National Museum of Natural History collection. The whales difered from all of their congeners by having the following unique characters: a substantially smaller body size of physically mature individuals, proportionately shorter beak, and darker body colour. Thus, we conclude that the whales are a third Berardius species. Beaked whales (Family Ziphiidae, Odontoceti, Cetacea) include the second largest number of species among toothed whale families. Teir preference for deep ocean waters, elusive habits, and long dive capacity1 make beaked whales hard to see and inadequately understood. A total of 22 species are currently recognized in six genera (Berardius, Hyperoodon, Indopacetus, Mesoplodon, Tasmacetus, and Ziphius)2. Te genus Berardius has two species, Baird’s beaked whale Berardius bairdii, found in the North Pacifc and adjacent waters, and Arnoux’s beaked whale B.

The Bowhead Vs. the Gray Whale in Chukotkan Aboriginal Whaling IGOR I
ARCTIC VOL. 40, NO. 1 (MARCH 1987) P. 16-32 The Bowhead vs. the Gray Whale in Chukotkan Aboriginal Whaling IGOR I. KRUPNIK’ (Received 5 September 1984; accepted in revised form 22 July 1986) ABSTRACT. Active whaling for large baleen whales -mostly for bowhead (Balaena mysricetus) and gray whales (Eschrichrius robustus)-has been practiced by aborigines on the Chukotka Peninsula since at least the early centuries of the Christian era. Thehistory of native whaling off Chukotka may be divided into four periods according to the hunting methods used and the primary species pursued: ancient or aboriginal (from earliest times up to the second half of the 19th century); rraditional (second half of the 19th century to the1930s); transitional (late 1930s toearly 1960s); and modern (from the early 1960s). The data on bowhead/gray whale bone distribution in theruins of aboriginal coastal sites, available catch data from native settlements from the late 19th century and local oral tradition prove to be valuable sources for identifying specific areas of aboriginal whaling off Chukotka. Until the 1930s, bowhead whales generally predominated in the native catch; gray whales were hunted periodically or locally along restricted parts of the coast. Some 8-10 bowheads and 3-5 gray whales were killed on the average in a “good year”by Chukotka natives during the early 20th century. Around the mid-20th century, however, bowheads were completely replaced by gray whales. On the basis of this experience, the author believes that the substitution of gray whales for bowheads, proposed recently by conservationists for modemAlaska Eskimos, would be unsuccessful.

Fin Whale Balaenoptera Physalus
Natural Heritage Fin Whale & Endangered Species Balaenoptera physalus Program State Status: Endangered www.mass.gov/nhesp Federal Status: Endangered Massachusetts Division of Fisheries & Wildlife DESCRIPTION: Fin Whales can weigh between 40 and 80 tons and measure 22 to 26 meters long, second in size only to the Blue Whale. Females tend to be slightly larger than males by 5-10%. Fin Whales have a sleek, streamlined body with a V-shaped head and are dark grey to brown on top, with white underneath. They have a tall, hooked, dorsal fin located two-thirds of the way down their body. Fin Whales are commonly called Razorbacks for the ridges on the middle of the back behind the dorsal fin. The unique asymmetrical coloration on the head easily separates this species from all of the other baleen whales. On the right side, the lower jaw is white, and the baleen plates in the front half of the mouth are also white, but abruptly change to dark Photo courtesy of NOAA in the back half of the mouth. By contrast, the lower left jaw is gray and all of the baleen plates on the left side are dark. This coloration may aid in herding fish during east of Boston and Cape Ann. Although there are feeding, although its primary purpose is unknown. seasonal fluctuations, the Fin Whale is most common in New England from April to November.

Gray Whales - Current Status and Strandings
San Francisco Bay National Wildlife Refuge Complex Tideline Newsletter Archives Gray whales - current status and strandings by Doreen Moser and Frances Gulland As winter begins here in California, so does the annual gray whale (Eschrichtius robustus) migration. In November, the whales begin their 5,000-mile journey south ward from Alaska’s Bering and Chukchi Seas. During December and January thou sands of these whales are seen migrating along our coast. By January, pregnant fe males are first to reach the calving lagoons along the West coast of Baja California, Mexico. Soon they are joined by the other adults and juveniles. The females give birth to their calves in the lagoons, usually for the first time when eight years old. In February, the animals begin another 5,000 mile jour ney northward returning to Alaska. During the spring months, cow-calf pairs can be seen migrating very close to shore. These 15-foot calves nurse constantly, as they migrate back to the summer feeding grounds. As you stand along the shore, how do you know you are looking at a gray whale? You can usually spot them by their heart-shaped blow. They surface regularly every three to five minutes when migrating, and usually blow three to five times. They swim between 7 and 9 kms per hour. Gray whales are medium sized whales, reaching up to 45 feet in length and weighing 45 tons. As in other baleen whales, females are larger than the males. Gray whales can be distin guished from other whales because they lack a dorsal (back) fin.

Fall Feeding Aggregations of Fin Whales Off Elephant Island (Antarctica)
SC/64/SH9 Fall feeding aggregations of fin whales off Elephant Island (Antarctica) BURKHARDT, ELKE* AND LANFREDI, CATERINA ** * Alfred Wegener Institute for Polar and Marine research, Am Alten Hafen 26, 256678 Bremerhaven, Germany ** Politecnico di Milano, University of Technology, DIIAR Environmental Engineering Division Pza Leonardo da Vinci 32, 20133 Milano, Italy Abstract From 13 March to 09 April 2012 Germany conducted a fisheries survey on board RV Polarstern in the Scotia Sea (Elephant Island - South Shetland Island - Joinville Island area) under the auspices of CCAMLR. During this expedition, ANT-XXVIII/4, an opportunistic marine mammal survey was carried out. Data were collected for 26 days along the externally preset cruise track, resulting in 295 hrs on effort. Within the study area 248 sightings were collected, including three different species of baleen whales, fin whale (Balaenoptera physalus), humpback whale ( Megaptera novaeangliae ), and Antarctic minke whale (Balaenoptera bonaerensis ) and one toothed whale species, killer whale ( Orcinus orca ). More than 62% of the sightings recorded were fin whales (155 sightings) which were mainly related to the Elephant Island area (116 sightings). Usual group sizes of the total fin whale sightings ranged from one to five individuals, also including young animals associated with adults during some encounters. Larger groups of more than 20 whales, and on two occasions more than 100 individuals, were observed as well. These large pods of fin whales were observed feeding in shallow waters (< 300 m) on the north-western shelf off Elephant Island, concordant with large aggregations of Antarctic krill ( Euphausia superba ). This observation suggests that Elephant Island constitutes an important feeding area for fin whales in early austral fall, with possible implications regarding the regulation of (krill) fisheries in this area.

GORDON, Department of Ecology and Evolutionary Biology, University of California, 621 Charles E. Young Drive South, Los Angeles, California 90095-1606, U.S.A. Abstract Rorqual whales (Family: Balaenopteridae) are the world’s largest predators and sometimes feed near or at the sea surface on small schooling prey. Most rorquals cap- ture prey using a behavioral process known as lunge-feeding that, when occurring at the surface, often exposes the mouth and head above the water. New technology has recently improved historical misconceptions about the natural variation in rorqual lunge-feeding behavior yet missing from the literature is a dedicated study of the identification, use, and evolution of these behaviors when used to capture prey at the surface. Here we present results from a long-term investigation of three rorqual whale species (minke whale, Balaenoptera acutorostrata; fin whale, B.
