    On 20 July 2020, the partial skeletal of a gray whale was found on the coast near the mouth of Notoro Lagoon in Abashiri, Hokkaido, Japan, facing the southern Okhotsk Sea (44.105° N, 144.175° E). This is the first confirmed stranding of a gray whale on the Hokkaido coast of the Okhotsk Sea. The recovered bones were a posterior part of skull, the right mandible, four caudal and one caudal or lumbar vertebrae, two epiphyseal plates and a single phalanx. The length of the right mandible was 150 cm in a straight line. The body length was estimated 790 cm by the length of mandible, which means the whale was less than one year old at the time of death.


  • Ice-related Strandings of Killer Whales at Shore in the Southern Okhotsk Sea

    Killer whales are extensively distributed throughout the world's oceans and migrate to areas where there is seasonal and year-round sea ice. Even at the southern tip of the Okhotsk Sea, the lowest latitudes where the offshore formation sea ice exists, killer whales are commonly observed during the winter months. At least eight ice-related strandings at the shore of killer whales occurred in Etorofu Island, Hokkaido, and southern Sakhalin between 1925 and 2016. These strandings were observed roughly once per decade. All stranding events occurred with drift ice floe, and not in fast ice. The thickness and density of sea ice floes were different among the events, e.g., from a primary ice floe to a separated front mass or small ice floe fragment in geological scale or from a large ice cake to brash ice debris. Until the 1970s, the response of the locals was food consumption of whale meat; however, rescue efforts were attempted for three cases in the 21st century.

    More than 50 Far Eastern glass negatives taken by H. G. Melsom in around 1900 were preserved in a museum in Norway. Among these, on 13 images related to Korean coastal whaling, the location and subjects were examined and identified. These images included; the Jangsaengpo whaling station in Ulsan, Jangjeon Bay and Mt. Kumgang, the whale catcher Georgiy and her crew from the Russian Pacific Fisheries Co., the whale catcher Main chartered by Nagasaki whaling Co. and Kosuge Slip Dock, a World Cultural Heritage site, in Nagasaki. The image that portrays whaling on the Korean Peninsula at the beginning in the 20th century is rare and those images with high resolution are extremely valuable.
