Ulban Bay

Ulban Bay (Russian: ''Ul'bansky Zaliv'') is a bay in the northwestern Sea of Okhotsk, just south of the Shantar Islands. It is a southern branch of Academy Bay to the north. The Syran and Ulban rivers flow into its head.

Geography

Ulban Bay is entered between Cape Ukurunru to the west and Cape Tukurgu to the east, which are separated by 43.4 km (about 27 mi). The bay itself is nearly 64 km (40 mi) deep in a southwesterly direction. Ice usually leaves Ulban Bay by mid- or late June, but in some years may remain until August. The bay has no safe anchorage and is exposed to northeast winds. Tides are semidiurnal. Springs rise 4.9 m (16 ft) in the northern part of the bay and 5.4 m (17.7 ft) in the southern part, while neaps rise about 3 m (9.8 ft). Tidal currents vary from one to two knots. The flood current generally sets to the southwest, while the ebb flows in the opposite direction.United States. (1918). ''Asiatic Pilot, Volume 1: East coast of Siberia, Sakhalin Island and Chosen''.

History

Between 1854 and 1885, American whaleships frequented the bay hunting bowhead whales. They called it Mercury or Dimon's Bay, after the ship ''Mercury'' (340 tons), of New Bedford, which visited the area during her voyage of 1852-1855, and Francis L. Dimon, her master at the time. They also anchored at the head of the bay to obtain wood and water. On 9 July 1855, the ship ''Washington'' (340 tons), of Sag Harbor, was damaged by ice and run ashore, being sold at auction for $400 — the wreck was still visible in October.''Mary Frazier'', of New Bedford, July 9, Oct. 19-21, 1855, NWC.

Russian schooners and boat crews from Mamga also cruised for bowheads in the bay from 1865 to 1871.Lindholm, O. V., Haes, T. A., & Tyrtoff, D. N. (2008). ''Beyond the frontiers of imperial Russia: From the memoirs of Otto W. Lindholm''. Javea, Spain: A. de Haes OWL Publishing.

Wildlife

In the summer beluga whales aggregate in the mouths of the Syran and Ulban rivers at the head of Ulban Bay,Solovyev, B. A., Shpak, O. V., Glazov, D. M., Rozhnov, V. V., & D. M. Kuznetsova. (2015). "Summer distribution of beluga whales (''Delphinapterus leucas'') in the Sea of Okhotsk". ''Russian J. Theriol.'' 14 (2): 201-215. while bowhead whales are also common in the bay during that time of year.Shpak, O. V., Meschersky, I. G., Chichkina, A. N., Kuznetsova, D. M., Paramonov, A. Y., & V. V. Rozhnov. (2014). "New data on the Okhotsk Sea bowhead whales". ''Paper presented to the Scientific Committee of IWC 65''. 5 pp. In July 2011, an endangered North Pacific right whale was photographed in the bay – which is considered a vagrant to the region.Ovsyanikova, E., Fedutin, I., Belonovich, O., Burdin, A., Burkanov, V., Dolgova, E., Filatova, O., Fomin, S., Hoyt, E., Mamaev, E., Richard, G., Savenko, O., Sekiguchi, K., Shpak, O., Sidorenko, M. and Titova, O. (2015). "Opportunistic sightings of the endangered North Pacific right whales (''Eubalaena japonica'') in Russian waters in 2003–2014". ''Mar. Mam. Sci.'' 31: 1559–1567. Waders use the southern part of the bay as a stopover during their summer migration. The most abundant species are Terek sandpiper, Great knot, and wood sandpiper.Pronkevich, V. V. (1998).
