The North Pacific

The North Pacific right whale (Eubalaena japonica) is among the most endangered of all great whales, having been subject to intensivecommercial whaling in the 19th century. All available 20th century records of this species in the North Pacific were reviewed. There hasbeen a total of 1,965 recorded sightings since 1900; of these, 988 came from the western North Pacific, 693 from the eastern North Pacificand 284 had no location specified. Thirteen strandings (all but one from the western North Pacific) were recorded. Known catches forcommercial or scientific purposes totalled 742 (331 in the western North Pacific, 411 in the eastern North Pacific). Most of the reportedSoviet ‘sightings’ in the eastern North Pacific were actually catches, as may be the case for Soviet sightings in the Okhotsk Sea. In addition,the impact of known Soviet illegal catches in the Okhotsk Sea may be reflected in an apparent decline in sightings after the 1960s (althoughthis may be partly explained by low observer effort). Overall, the data support the hypothesis that at least two stocks of right whales existin the North Pacific. Any recovery in the western North Pacific population was compromised by the Soviet catches in the Okhotsk region,although recent sightings suggest that this population is still large enough to sustain reproduction. By contrast, Soviet catches in thenow-smaller eastern North Pacific population have severely reduced its prospects for recovery. Although the prognosis for this populationis poor, a long-term monitoring programme is required to better understand its conservation status and to determine whether it may beaffected by human-related problems that would require mitigation.

AbstractSummertime temperatures in marginal seas are, in general, colder than on the surrounding continent because of the large contrast in heat capacity between the land and the ocean. The Okhotsk Sea, which is covered by sea ice until early summer, is much colder than the surrounding continent in summer. The Okhotsk Sea is thus located in an area with one of the largest temperature contrasts of all the marginal seas in summertime midlatitudes. Cooled air over the Okhotsk Sea may have an impact on remote summer climates, such as by serving as the source of cold-air advection that results in a poor crop harvest in Japan. Here, we examine the role of the Okhotsk Sea on the early summer climate of the western part of the North Pacific through an ideal numerical experiment by artificially changing the model’s default oceanic condition in the Okhotsk Sea to a condition of land cover. Simulation results reveal that the presence of the Okhotsk Sea increases precipitation of the baiu/mei-yu front through strengthening of the northward moisture flux at the western edge of an intensified North Pacific subtropical high. The Okhotsk influence farther extends toward western North America to which the strengthened jet stream with a storm track extends. This remote influence is achievable through feedback from a transient eddy anomaly that is activated by the surface temperature gradient between the cold Okhotsk Sea and the warm Pacific Ocean. The findings imply that the existence of the Okhotsk Sea strengthens the East Asian summer monsoons.
