SESSION I : Geographical Names and Sea Names The 14th International Seminar on Sea Names Geography, Sea Names, and Undersea Feature Names Acceptance and Usage of the toponym, East Sea in Scientific and Popular Literature Norman Z. Cherkis (Consultant, Five Oceans Consultants, U.S.A.) Background: Maritime toponyms refer to large bodies of water, parts of those large bodies of water, and undersea features. Many surface regions have been named for hundreds and sometimes thousands of years as in the case of the “East Sea.” The present-day international maritime community, including most governmental agencies however, has been using the term, “Sea of Japan,” exclusively for that body of water for most of the last 100 years or so. The main reason for using Japanese terminology is because after Japan successfully annexed Korea in the early 20th Century, the empire of Japan embarked on a campaign to systematically remove all vestiges of the Korean heritage, including the Korean language. This practice continued until the end of the Second World War, in 1945. After the cessation of hostilities the Korean nation was reinstated in the company of nations of the world and the Korean language was reestablished in the Republic of Korea. The new Korean national anthem has, as its first two words, “Dong Hae…” which translates at “East Sea.” The use of the toponym, “East Sea” or, in Korean, “Dong Hae”can be traced back at least two millennia. At that time, ancient China was dominant in the region and used the term East Sea to indicate that direction from their eastern coastline, and those that eluded destruction during informational “purges” of several Chinese emperors over the past 100 years are now housed in great historical libraries mostly located in China and Korea.. The History of the Three Kingdoms, Samguksagi), an ancient Korean writing dating to approximately 50 years Before the Common Era (BCE). Another reference to Dong Hae appears on a stele to King Gwanggaeto and dates to 414 of the Common Era. The name East Sea was established long before Japan was even known to exist to the western world, for the mariners of the times seldom traveled very far from their home shores. The first western reference to the East Sea is attributed to a world map created in the 13th Century, outlining the travels of Giovanni di Plano Carpini in eastern and Central Asia between 1245 to 1247, C.E. That map is unfortunately lost, but a copy from ca.1434 is known to exist, and it presently resides at Yale University. (Fig. 1). 193 The 14th International Seminar on Sea Names Geography, Sea Names, and Undersea Feature Names Portion of the copy of the di Plano Carpini map of 1434. Maereum Orientale (East Sea) is clearly visible near the upper right portion of the land masses. (fig. 1) The first written reference to the Sea of Japan known to exist in western geographic materials goes to the time of a missionary-priest, Matteo Ricci. S.J., the founder of Catholic Missions in China after 1582 C.E, some 148 years after the copied di Plano Carpini map was published. Father Ricci possibly used the Carpini map, but used the name “Sea of Japan” in a 1602 document in which a map was included. A number of scholarly papers and monographs have been published regarding usage of the East Sea and the Sea of Japan, including variations thereof and arguments for which name should be used in the 21st Century, but these do need to be mentioned here. These arguments can be found in great detail by searching on the terms East Sea and Sea of Japan on Internet search engines. The arguments, most of which are nationalistic in nature were written mainly by Korean and Japanese authors, who wish to establish a proper toponym for the body of water between Korea and Japan. Some of these arguments have been particularly unflattering to the side with the opposing opinions, resulting in emotional interchanges, again, posted mostly on Internet blogs. 194 The 14th International Seminar on Sea Names Geography, Sea Names, and Undersea Feature Names Moving fast-forward toward the 21st Century, we must pause in the mid-20th Century because, as early as March, 1969, the National Geographic Society, an international geography and map publisher of great regard throughout the world, published a map of Korea on page 308 of an article that shows the name, East Sea used as an alternate name for the Sea of Japan. (Fig. 2). © National Geographic Society, 1969 (fig. 2) Indeed, in this earliest part of the 21st Century, ALL major producers of family, school and scholarly atlases, e.g., The Times Atlas, Rand-McNally World Atlas, Langenscheidt Publishers Atlas, Collins World Atlas, National Geographic World Atlas and many others, when publishing Roman-alphabet atlases all give equal importance to the body of water called the EAST SEA and the SEA OF JAPAN. East Sea/Sea of Japan Toponyms East Sea/Sea of Japan toponyms discussed here deal mainly with features completely OUTSIDE of the territorial limits of the nations that border the region, i.e., beyond 12 195 The 14th International Seminar on Sea Names Geography, Sea Names, and Undersea Feature Names nautical miles from the shores of Korea, Japan and Russia. Early 20th Century maps note the existence of the Korea/Tsushima Strait, that body of water that separates Korea and Japan and though which a branch of the oceanographically important Kuroshio Current flows northward. The Strait contains a Japanese island, Tsushima, hence it was given the name, Tsushima Strait a bit over 100 years ago, during the beginning of the Japanese colonial annexation of Korea. However, a significant number of western publications, dating from the middle 1850s, show it as Korea Strait, or the equivalent in other Indo-European tongues. Tsushima Basin is a name applied to a more-or less-circular depression in the southwestern-most East Sea/Sea of Japan. According to IHO/IOC publication B-6 guidelines, “The first choice of a specific term, where feasible, should be one associated with a geographical feature: e.g., Aleutian Ridge, Aleutian Trench….” The nearest geographical feature to this depression is Ulleung-Do (Ulleung Island), and therefore, according to the IHO/IOC principles for naming undersea features, should be called Ulleung Basin because the basin is immediately adjacent to Ulleung-Do. However, since the name Tsushima Basin has been previously used in the scientific and geographic literature, and almost exclusively between 1910 and 1970 due to political events that will not be addressed here, Tsushima Basin should be retained as a variant name within gazetteers, or used concurrently with Ulleung Basin, as can be seen in the appended reference list.. Ulleung Plateau is the geological platform upon which the island of Ulleung-Do is situated. Still being investigated, more papers will, I am sure, be forthcoming. During the 20th meeting of the GEBCO Sub-Committee on Undersea Feature Names (GEBCO-SCUFN), held in Monaco in June of 2007, the recently-formed Korean Committee on Undersea Feature Names (K-CUF) submitted ten (10) names for approval by he Sub-Committee. Those names are Anyongbok Seamount, Gangwon Plateau, Hupo Bank, Igyuwon Seamount, Kimmu Seamount, Onnuri Basin, Saenal Basin, Ulleung Plateau, Usan Escarpment and Usan Trough. Most of these features were recently discovered in the undisputed part of the East Sea / Sea of Japan by Korean research vessels. (fig. 3) 196 The 14th International Seminar on Sea Names Geography, Sea Names, and Undersea Feature Names (Fig. 3) Locations of undersea toponyms. (From: Ocean Atlas of Korea |East Sea|; NORI, Republic of Korea, 2007) All of the above names were approved by unanimous vote of the GEBCO Sub- Committee and will be placed in the GEBCO Gazetteer of Undersea Feature Names (IHO- IOC Publication, B-8), and Kang, Han, et al., (2007) have already described Anyongbok Seamount in a refereed scientific journal. The 21st meeting of GEBCO-SCUFN was held in mid-May, 2008 on Jeju Island, Korea. At that meeting the Korean Committee on Undersea Feature Names (K-CUFN) proposed 8 undersea feature names, 4 of which are in the East Sea: Jugam Ridge, Ulsan Seachannel, Usan Ridge and Wangdol Reef. All of the names were approved by the GEBCO-SCUFN committee and presented to the Guiding Committee for final approval. 197 The 14th International Seminar on Sea Names Geography, Sea Names, and Undersea Feature Names The names will appear in the next version of the IHO-IOC Gazetteer of Undersea Feature Names—Publication B-8, and will be available on the IHO website. Statistics: In 2006, an extensive literature search of non-Korean-language publications was initiated, to locate print-media articles that support the Korean position: alternate names can be and have been used within the science community. At the time of this writing, 579 papers (listed in the appendix to this paper) have been located in published literature and governmental sources which support the position of using either alternate- or co-naming of features in the East Sea / Sea of Japan. ALL subaerial toponyms of the East Sea / Sea of Japan are too many to enumerate and are listed in national and international gazetteers. However, for relevance in this paper only, the subaerial toponyms have been limited to the following: East Sea/Sea of Japan and Korea Strait / Tsushima Strait. Of the 579 papers, 469 contain the toponym, EAST SEA, in either the title or in the text. 128 contain the toponym, KOREA STRAIT , in either the title or in the text Of those features that are entirely submerged in the East Sea / Sea of Japan, 125 contain the toponym, ULLEUNG BASIN , in either the title or in the text 9 contain the toponym, ULLEUNG [INTERPLAIN] GAP , in either the title or in the text 198 The 14th International Seminar on Sea Names Geography, Sea Names, and Undersea Feature Names 15 contain the toponym, KOREA PLATEAU , in either the title or in the text 3 contain the toponym, ONNURI BASIN, in either the title or in the text 1 contains the toponym, ULLEUNG PLATEAU, in either the title or the text 1 contains the toponym, ANYONGBONG SEAMOUNT in both the title and the text and one paper contained all of the following toponyms as well: ULJIN FAN, JUKSAN SEAMOUNT CHAIN, ULLEUNG SEAMOUNT, HUPO BANK, HUPO BASIN.

AVISO 19 satellite altimetry data and OFES (OGCM for the Earth Simulator) results indicate that the variation 20 propagates clockwise from Japan's east coast through the Tsushima Strait into the Japan/East Sea (JES) 21 and then northward along the west coast. In this study, we hypothesize and test numerically that the sea 22 level variability along the west coast of Japan is remotely forced by the Kuroshio Extension (KE) off the 23 east coast. Topographic Rossby waves and boundary Kelvin waves facilitate the connection. Our 3-d 24 POM model when forced by observed wind stress reproduces well the seasonal changes in the vicinity 25 of JES. Two additional experiments were conducted to examine the relative roles of remote forcing and 26 local forcing. The sea level variability inside the JES was dramatically reduced when the Tsushima Strait 27 is blocked in one experiment. The removal of the local forcing, in another experiment, has little effect on 28 the JES variability.

The NLOM results elucidate the impact of eddy variability on the EKWC separation from the Korean coast. Eddy variability is suppressed by either increasing the model viscosity or decreasing the model resolution. The simulations with decreased eddy variability indicate a northward overshoot of the EKWC. Only the model simulation with sufficient eddy variability depicts the EKWC separating from the Korean coast at the observed latitude. The NLOM simulations indicate mesoscale influence through upper ocean–topographic coupling. 1. Introduction Lie et al., 1995).

This AT is caused by a layer of sub-surface gas, which prohibits the identification of geological structures below that gas layer. Sound speeds were measured directly in these sediments using the Acoustic Lance (AL) in both mid- and late-September 1999. In situsoundspeeds obtained in mid-September varied between 1400 and 1550 m/s, and thus did not confirm the presence of gas within the top 3.5 m of the seafloor. However, signal waveforms suggested that a gassy layer might have been just below the depth penetrated by the Lance.

  • Phylogeography Reveals an Ancient Cryptic Radiation in East-Asian Tree
    Dufresnes et al. BMC Evolutionary Biology (2016) 16:253 DOI 10.1186/s12862-016-0814-x RESEARCH ARTICLE Open Access Phylogeography reveals an ancient cryptic radiation in East-Asian tree frogs (Hyla japonica group) and complex relationships between continental and island lineages Christophe Dufresnes1, Spartak N. Litvinchuk2, Amaël Borzée3,4, Yikweon Jang4, Jia-Tang Li5, Ikuo Miura6, Nicolas Perrin1 and Matthias Stöck7,8* Abstract Background: In contrast to the Western Palearctic and Nearctic biogeographic regions, the phylogeography of Eastern-Palearctic terrestrial vertebrates has received relatively little attention. In East Asia, tectonic events, along with Pleistocene climatic conditions, likely affected species distribution and diversity, especially through their impact on sea levels and the consequent opening and closing of land-bridges between Eurasia and the Japanese Archipelago. To better understand these effects, we sequenced mitochondrial and nuclear markers to determine phylogeographic patterns in East-Asian tree frogs, with a particular focus on the widespread H. japonica. Results: We document several cryptic lineages within the currently recognized H. japonica populations, including two main clades of Late Miocene divergence (~5 Mya). One occurs on the northeastern Japanese Archipelago (Honshu and Hokkaido) and the Russian Far-East islands (Kunashir and Sakhalin), and the second one inhabits the remaining range, comprising southwestern Japan, the Korean Peninsula, Transiberian China, Russia and Mongolia. Each clade further features strong allopatric Plio-Pleistocene subdivisions (~2-3 Mya), especially among continental and southwestern Japanese tree frog populations. Combined with paleo-climate-based distribution models, the molecular data allowed the identification of Pleistocene glacial refugia and continental routes of postglacial recolonization. Phylogenetic reconstructions further supported genetic homogeneity between the Korean H.

  • The Naming of the Korea Strait on Old Maps
    The Naming of the Korea Strait on Old Maps Bo-Kyung Yang (Director of Korean Institute of Geographical Research, Sungshin Women's University, the Republic of Korea) Preface In addition to naming the East Sea (Sea of Japan), which emerged as a subject of international dispute, the Korea Strait(大韓海峽), off the East Sea coast in the South, is also a matter of intense attention for Korea and Japan as they use different names for the Strait. The Korea Strait, a narrow strait with an average width of about 200km is located between the Southeast coast of Korea and the Japanese islands, linking the Yellow Sea, the South and East Sea, and the East China Sea. The Tsushima Island(對馬島) lies in the center of the Strait and the island is divided into a West channel(東水道) and East channel(西水道). The Korea Strait, which lies between Korea and the Kyushu Island, is about 200km in length and width but the width of the narrowest point extends only about 50km. It is a relatively shallow with a maximum depth of 210m. From ancient times, it has been an important sea route between Korea and Japan. Japan named the Strait ‘Tsushima Strait’ (對馬海峽), sometimes they called the Western part of the Tsushima ‘Korea Strait’ and Eastern part ‘Tsushima Strait’. This article examined the changes of the name of the Strait based on the old maps of Korea, Japan, and Western countries, which were produced between the 16th century and early 20th century. Maps used for analysis are Korean maps owned by libraries and museums and 74 Japanese maps from <Map of Eight Provinces of Korea> produced in 1747 to <Map of Korea> in 1941.

However, the key dynamic factors driving them remained unclear. Our model and Kuroshio theoretical analysis show that wind stress over the open Pacific Ocean east of Japan drives a net equatorward Shelf circulation water flux of 2.2 Sv, and this flux sets up a south-north sea surface drop from the East China Sea (ECS) to the Cross-shelf intrusion Japan Sea which drives a throughflowof 2.6 Sv poleward through the Tsushima Strait. This throughflowrequires a shelf circulation in the ECS to balance the mass flux. Thus, the Kuroshio Current must intrude onto the ECS shelf and there must be a poleward flowing Taiwan Warm Current through Taiwan Strait.
