Eduard Dallmann, of Blumenthal on the lower Weser, went to sea at the age of 15 in 1845. He took command of his first ship, the whaling vessel Planet, in 1859 on a whaling voyage to the sperm whaling grounds in the Pacific and to the Sea of Okhotsk. Over the period 1864–66 he commanded the Hawaiian vessel W.C. Talbot on trading voyages to the Alaskan and Chukotka shores of the Bering and Chukchi seas. On 17 August 1866 he sighted and landed on Ostrov Vrangelya (Wrangel Island), a year prior to its sighting by Thomas Long, credited by many with the first sighting. For the following three years he commanded the whaling ship Count Bismarck on a whaling cruise to the tropics, the Sea of Okhotsk, and the Bering and Chukchi seas. In 1873–74 he made the first Antarctic whaling voyage aboard Groenland, and discovered and charted the west coasts of Anvers, Brabant, and Liège islands, as well as many smaller islands and straits including Bismarck Strait. He spent the 1875 whaling season as expert consultant, still aboard Groenland, on the Davis Strait and Baffin Bay whaling grounds. Then, to complete his career in polar waters, from 1877 to 1883 he made annual attempts to haul freight to the mouth of the Yenisey River, to be exchanged for grain cargoes brought down that river by barge. Of the seven attempts, only four were successful, the rest being foiled by ice conditions in the Kara Sea, and on the basis of this record, Baron von Knoop, the Russian entrepreneur who was financing the operation, decided to cut his losses. This ended Dallmann's career in polar waters.

The revision of the herbarium material, collected in the northern part of the Sea of Okhotsk in 1965–1966 and stored in VNIRO, allowed to expand the taxonomic list of macrophyte algae of the coastal zone of this area. The locations of discovery of 24 previously unmentioned species are described. Myrionema balticum, Ulvella repens, Syncoryne reinkei, Acrochaetium arcuatum were found in the Sea of Okhotsk for the first time. Most species new for the Sea of Okhotsk is represented by epiphytes of the family Ulvellaceae (Chlorophyta). The final taxonomic list of this region, including literature data, consists of 169 species.

80 sediment stations collected along the meridian transect across the Sea of Okhotsk were studied in order to reveal patterns of dissolution based on planktonic foraminifera. The degree of calcite dissolution intensity from planktonic foraminifera determined by different indices (degree of fragmentation, presence of susceptible to dissolution species, benthos/ plankton ratio). The highest degree of dissolution evidenced by a large number of shell fragments and corroding walls were found in sediments from the area of the Kuril Islands. The most revealing measure of probable dissolution of foraminiferal shells in the central part of the sea is a low number and lack of thin-walled species. The effects of dissolution on foraminiferal shells were studied for dominated species Neogloboquadrina pachyderma sin and Globigerina bulloides using a scanning electron microscope. The results are important for understanding processes of sedimentation, the paleo-oceanologial reconstructions and for obtaining reliable results in isotope analyzes.

For the first time the morphology of the decapodid stage of Neocrangon communis is described in detail. The decapodid can be distinguished from those of the genera Argis, Crangon, and Mesocrangon by the morphology of their telson, antennae, antennulae, and carapace. The main distinguishing features of the decapodid of N. communis were two spines on medial line of the carapace, a short rostrum, relatively wide scaphocerite, characteristic shape and length of the terminal setae on the telson. Drawings of general view and some limbs are presented.
