Bowhead whales, Balaena mysticetus, were recorded during their spring migration past Point Barrow, Alaska, in 1979 and 1980 using a pair of hydrophones linked to an underwater sound direction finding device. A great variety of sounds were recorded, including types that have been reported previously for bowheads during their spring migration, fall migration, and summer feeding. Most of the sounds were below 300 Hz with simple frequency-modulated structures. A variety of pulsive sounds were also recorded; these contained complex energy up to 3500 Hz. Sound levels of approximately 156 dB (re 1 μPa) were recorded for one whale 100–150 m from the hydrophones. We did not observe any particular behaviors which correlated with any of these sounds.

One specimen of the trematode Ogmogaster antarcticus Johnston, 1931 was recovered from a sample of bowhead whale ingesta collected at Barrow, Alaska. This represents a new host record and extends the known geographic distribution of this helminth some 5000 km by sea north of British Columbia, Canada.

Abstract Full mitochondrial genomes were assembled for 12 recently sampled animals from the Svalbard bowhead whale (Balaena mysticetus) stock via high-throughput sequencing data, facilitating analysis of the demographic history of the population for the first time. The Svalbard population has retained noticeable amounts of mitochondrial genome diversity despite extreme historical harvest levels. Haplotype and nucleotide diversities were similar to those estimated earlier for other bowhead whale populations. The reconstructed demographic history was in accordance with a boom–bust scenario, combining a slight Pleistocene population growth 25 000–35 000 years ago and a Holocene decline. Employing a mutation rate of 3.418 × 10–8 substitutions per site per year, the time to the most recent common ancestor for the mitochondrial genomes of the contemporary Svalbard bowhead whales was estimated to be 68 782 (54 353–83 216) years before the present. Based on 370 bp fragments of the D-loop region, significant genetic differentiation was detected between all extant bowhead whale populations across the circumpolar Arctic. Thus, the Svalbard bowhead whales can be regarded as a population with its own genetic legacy.
