Abstract A detailed spatial distribution of South Pacific Subtropical Mode Water (SPSTMW) and its temporal variation were investigated using the World Ocean Atlas (WOA) 2001 climatology and high-resolution expendable bathythermograph (HRX) line data. In the WOA 2001 climatology, SPSTMW can be classified into western and eastern parts. A detailed examination of spatial distributions using HRX-PX06 line data revealed that the eastern part can be further divided into two types by the Tasman Front (TF) extension. Consequently, SPSTMW can be classified into three types, referred to in the present study as the West, North, and South types. The West type, situated in the recirculation region of the East Australia Current (EAC), has a core layer temperature (CLT) of about 19.1°C; the North type, in the region north of the TF extension, has a CLT of about 17.6°C; and the South type, in the region south of the TF extension, has a CLT of about 16.0°C. The long-term (>6 yr) variations in the inventories of the three types were dissimilar to each other. The short-term (<6 yr) and long-term variations in the mean CLT of the North and South types were greater than that of the West type. Winter cooling in the previous year may have influenced the short-term variation in the South-type CLT. Moreover, the strength of the EAC may have influenced long-term variation in the West-type inventory and thickness and in the North-type thickness and CLT.

The bare and rocky hill known as Holyhead Mountain is of considerable interest in connection with recent geological events, standing as it does some thirty miles out from the highlands of Carnarvonshire into the Irish Sea Basin; and in such remarkable isolation, for it is much the highest of the five hills which rise above the general level of the platform of Anglesey.Its height is only 721 feet, but so strongly featured is it, especially towards the west, that one feels the term ‘mountain’ to be no misnomer, and can hardly believe it to be really lower than many of our smooth wolds and downs of Oolite and Chalk. Being composed, moreover, of white quartzite (or more properly of quartzite-schist), and being so bare of vegetation, it recalls much more vividly certain types of scenery in the Scottish Highlands than anything in those Welsh mountains that one sees from its sides. Towards the east it slopes at a moderate angle, but a little west of the summit it is traversed by a very strong feature, due to a fault, running nearly north and south, along which is a line of great crags, facing west, and prolonged northwards into the still greater sea cliffs towards the North Stack. Beyond this the land still remains high, but is smoother in outline, a somewhat softer series of rocks extending from the fault to the South Stack, where the high moors end off in great cliffs above the sea.

Theotokou lies at the south-eastern corner of the Magnesian peninsula, a little to the north of the bay of Kato Georgi. The site itself is the seaward end of a narrow valley, where a small brook discharges into a little cove just to the north of a hill called Kastro (Fig. 1). Here there stands a small chapel built in 1807, and dedicated to the Virgin. In the walls of the chapel itself are several ancient blocks, and north and south of it traces of walls are visible. Immediately to the west is a large mass of ruins formerly covered with brushwood; round these stand six fragments of Doric columns, and a seventh lies in a cornfield some distance to the west: an eighth, which was seen here, has disappeared. This place, the traditional site of Sepias, was first visited by a local gentleman, Theódoros Zirghános.

The casa degli amanti (house of the lovers), at the south-west corner of the insula, falls into two fairly distinct halves: the atrium complex, oriented on the street to the west, and the peristyle with its surrounding rooms, oriented on the street to the south and on the property boundary to the east. In the atrium complex, the atrium is misplaced to the south of the central axis, allowing space for two large rooms to the north, one of which was possibly a shop or workshop (5.50 m. × 4.70 m.), with a separate entry from the street (I 10, 10), while the other (5.80 m. × 4.50 m.), decorated with mythological wallpaintings and provided with a wide opening on to the peristyle, must have been a dining-room or oecus (room 8). Each of these had a segmental vault rising from a height of about 3.50 m. at the spring to slightly over 4 m. at the crown. In the first the vault is missing, but the holes for some of its timbers are visible in the east wall and a groove along the north wall marks the seating for the planking attached to them; at a higher level, in the north and south walls, are the remains of beam-holes for the joists of the upper floor or attic (see below). The arrangements in room 8 are now obscured by the modern vault constructed to provide a surface for the reassembled fragments of the ceiling-paintings; but the shape of the vault is confirmed by the surviving plaster of the lunettes, while a beam-hole for the lowest of the vault-timbers is visible above the corner of the western lunette in an early photograph (Superintendency neg. C 1944). The shop I 10, 10 had a small window high in the street wall to the south of Its entrance; whether there were any additional windows above the entrance, it is impossible to say, since this part of the wall is a modern reconstruction. Room 8 was lit by a splayed window cut in the angle of the vault and the eastern lunette, opening into the upper storey of the peristyle.


In the Western Midlands of England and along the Welsh Borderland a series of coalfields occurs parallel to the course of the River Severn, and, for the most part, situated to the West of that river. The main links in this chain begin in the North with the Shrewsbury coalfield. Next follows the Le Botwood area, then Coalbrookdale and the Wyre Forest. Further still to the South is the little coalfield of Newent in Gloucestershire. This line terminates in the Forest of Dean and Bristol coalfields. In addition, a few detached areas of coal measures, of which the Clee Hills are the most important, lie further to the West. To the North of Shrewsbury, the line is continued by the Denbighshire (Wrexham) and the Flintshire coalfields, both situated for the most part to the West of the Dee. There is little doubt that the coalfields lying along this line, roughly North and South, are not all related to one another, either stratigraphically or tectonically. We are concerned here with the fields beginning with the Shrewsbury and ending with the Newent areas, and more especially with that of the Wyre Forest. We may at once exclude from primary consideration the Forest of Dean and Bristol fields in the South, and the Dee Valley coalfields in the North, as being quite unrelated, at least stratigraphically, to the Wyre Forest.

A long-term reciprocal garden study was used to determine adaptive variation between Cycas micronesica K.D. Hill plants from north versus south Guam. Half-siblings from each location were planted as one-leaf seedlings in north and south gardens and monitored for 15 years. Stem height and diameter, and leaf number and maximum length were measured yearly. Survival and plant size traits were evaluated using a two-way factorial. In both locations, the local genotypes out-performed the foreign genotypes in terms of survival and growth. Survival of the foreign genotypes began to decline by year 4 and was less than 10% by year 15. Survival of the local genotypes was 70% for the north garden and 100% for the south garden. The north site was more hostile to plant performance because overall survival and plant growth were less than for the south site. The most likely environmental factor provoking local adaptation was highly contrasting soil characteristics between north and south Guam. The results indicates that long-term conservation success for C. micronesica and other cycad species must include the concept of local adaptation into decisions for transplantation and restoration projects.

Tung-Kang Fishing Harbor, which is about 16 km to the south of Kaohsiung Harbor, is a river harbor on the south-west coast of Taiwan. This harbor is located at the estuary of the Niu-Pu River, which meets the Tung- Kang River and the Kao-Ping River on the north side, (see Fig. 1) The original north and south jetties were constructed in 1959. Because the entrance is located at the meeting of the three rivers and the water depth at the entrance is shallower than that in the breaking zone, the entrance is easily chocked with sand during the summer season when the south-west wind and waves are strong. Therefore, dredging is always necessary to maintain the required depth. On. the other hand, because of the increasing number of fishing boats and deeper draft, the port cannot function effectively. There-fore, how to keep the required water depth at the entrance and to obtain a wider and stable water basin is an urgent problem with this harbor. Based on the sounding of 1973, the littoral drift is mainly from the south. In the next year the construction of a 176 m long new south jetty was begun to protect the entrance and to facilitate the sedimentation study. In 1975, the Taiwan Fisheries Consultants was appointed to undertake the investigation and long-term planning work. This project includes littoral process study, planning, model test and design. Finally it is recommended that an adequate layout of south and north jetties can solve the problem of accretation of the harbor entrance. The purpose of this paper is to describe some aspects with emphasis on how to prevent the shoaling of the entrance channel located at the meeting of the rivers.

Newspaper editors need to play their part in tackling the emerging HIV/AIDS epidemic in the South Pacific region as they have enormous influence and can make a difference. They can help challenge public opinion on HIV/AIDS that is often based on ignorance, fear and prejudice, and also step up coverage and allocate more space for information about prevention.

It is my purpose in this article to discuss the interpretation of the relief from the Ara Pacis, now in the Uffizi Gallery, which is traditionally known as the “Tellus relief” (plate IV).The most recent detailed discussion of the, Ara Pacis is the monograph of F. Studniczka, which marks a considerable advance on previous work. Studniczka shows that the west door was flanked by two reliefs having to do with legendary figures of Italic or Roman history; to the south, Aeneas sacrificing, and to the north, Mars gazing on the wolf and twins; while the east door was flanked to the south by the so-called “Tellus,” facing right, and to the north by a relief representing Roma and secondary figures, facing left. That the west end was the front of the structure is made clear by the fact that the figures of the north and south sides are facing in that direction.

The ancient kingdom of Orissa (Odra-deśa, whence Oṛeśá), strictly speaking, extended from the Kánsbáns river in the north to the Rasákuliá river near Ganjám in the south; and from the Bay of Bengal on the east far into the tangled mass of low hills in the west, in which latter direction its limits seem never to have been clearly defined. But the kings of Orissa were not satisfied with these boundaries. It is a common boast both in literature and on monuments that their kingdom stretched from the great to the little Ganges; that is to say, from the Bhágirathí (called by Europeans the Hugli or “Hooghly”) to the Godávarí. At various times different kings made good this boast by victorious campaigns, followed by temporary occupation of territory both to the north and south.

This article examines the relationship of the two Korean states to unification, as well as the policies and various programs of the presidents who ruled the country after the separation. The authors characterized inter-Korean relations as «a history of long-term conflicts and short-term cooperation». The history of post-party relations between the North and the South is also studied, the need for a national community, the current state of the integration environment and how the peaceful reunification of the two countries will take place.
