Paleoclimate and location of the border between Mediterranean climate region and the Saharo-Arabian Desert as revealed by speleothems from the northern Negev Desert, Israel, , Vaks A. , Barmatthews M. , Ayalon A. , Matthews A. , Frumkin A. , Dayan U. , Halicz L. , Mogilabin A. , Schilman B. ,
Speleothem bearing karstic caves of the northern Negev Desert, southern Israel, provides an ideal site for reconstructing the paleoclimate and paleo-location of the border between Mediterranean climate region and the Saharo-Arabian Desert. Major periods of speleothem deposition (representing humid periods) were determined by high resolution 230Th-U dating and corresponding studies of stable isotope composition were used to identify the source of rainfall during humid periods and the vegetation type. Major humid intervals occurred during glacials at 190-150[no-break space]ka, 76-25[no-break space]ka, 23-13[no-break space]ka and interglacials at 200-190[no-break space]ka, 137-123[no-break space]ka and 84-77[no-break space]ka. The dominant rainfall source was the Eastern Mediterranean Sea, with a possible small contribution from southern tropical sources during the interglacial periods. When the interglacial interval rainfall was of Eastern Mediterranean origin, the minimum annual rainfall was ~ 300-350[no-break space]mm; approximately twice than of the present-day. Lower minimum amounts of precipitation could have occurred during glacial periods, due to the cooler temperatures and reduced evaporation. Although during most of the humid periods the vegetation remained steppe with mixed C3 C4 vegetation, Mediterranean C3 type steppe-forest vegetation invaded southward for short periods, and the climate in the northern Negev became closer to Mediterranean type than at present. The climate was similar to present, or even more arid, during intervals when speleothem deposition did not occur: 150-144[no-break space]ka, 141-140[no-break space]ka, 117-96[no-break space]ka, 92-85[no-break space]ka, 25-23[no-break space]ka, and 13[no-break space]ka-present-day.Precipitation increase occurred in the northern Negev during the interglacial monsoonal intensity maxima at 198[no-break space]ka, 127[no-break space]ka, 83[no-break space]ka and glacial monsoonal maxima at 176[no-break space]ka, 151[no-break space]ka, 61[no-break space]ka and 33[no-break space]ka. However, during interglacial monsoonal maxima at 105[no-break space]ka and 11[no-break space]ka, the northern Negev was arid whereas during glacial monsoonal minima it was usually humid. This implies that there is not always synchroneity between monsoonal activity and humidity in the region.Oxygen isotopic values of the northern Negev speleothems are systematically lower than contemporaneous speleothems of central and northern Israel. This part is attributed to the increased rainout of the heavy isotopes by Rayleigh fractionation processes, possibly due to the farther distance from the Mediterranean coast

Controversy over the great flood hypotheses in the Black Sea in light of geological, paleontological, and archaeological evidence, , Yankohombach Valentina, Gilbert Allan S. , Dolukhanov Pavel,
Legends describing a Great Flood are found in the narratives of several world religions, and the biblical account of Noah's Flood is the surviving heir to several versions of the ancient Mesopotamian Flood Myth. Recently, the story of the biblical deluge was connected to the Black Sea, together with the suggestion that the story's pre-Mesopotamian origins might be found in the Pontic basin [Ryan, W.B.F., Pitman, III, W.C., 1998. Noah's Flood: The New Scientific Discoveries About the Event That Changed History. Simon and Schuster, New York]. Based on the significance of this flood epic in the Judeo-Christian tradition, popular interest surged following publication of the idea.Currently, two Great Flood scenarios have been proposed for the Black Sea: (1) an Early Holocene event caused by catastrophic Mediterranean inflow at 7.2 ky BP (initial hypothesis of [Ryan et al., 1997. An abrupt drowning of the Black Sea shelf. Marine Geology 138, 119-126]) or 8.4 ky BP (modified hypothesis of [Ryan et al., 2003. Catastrophic flooding of the Black Sea. Annual Review of Earth and Planetary Science 31, 525-554.); and (2) a Late Pleistocene event brought on by Caspian influx between 16 and 13 ky BP [Chepalyga, A.L., 2003. Late glacial Great Flood in the Black Sea and Caspian Sea. GSA Annual Meeting and Exposition, 2-5 November 2003, Seattle, USA, p. 460]. Both hypotheses claim that the massive inundations of the Black Sea basin and ensuing large-scale environmental changes had a profound impact on prehistoric human societies of the surrounding areas, and both propose that the event formed the basis for the biblical Great Flood legend.This paper attempts to determine whether the preponderance of existing evidence sustains support for these Great Floods in the evolution of the Black Sea. Based upon established geological and paleontological data, it finds that the Late Pleistocene inundation was intense and substantial whereas the Early Holocene sea-level rise was not. Between 16 and 13 ky BP, the Late Neoeuxinian lake (the Late Pleistocene water body in the Pontic basin pre-dating the Black Sea) increased rapidly from ~-14 to -50 m (below the present level of the Black Sea), then rose gradually to ~-20 m by about 11 ky BP. At 11-10 ky BP (the Younger Dryas), it dropped to ~-50 m. When the Black Sea re-connected with the Sea of Marmara at about 9.5 ky BP, inflowing Mediterranean water increased the Black Sea level very gradually up to ~-20 m, and in so doing, it raised the salinity of the basin and brought in the first wave of Mediterranean immigrants. These data indicate no major drawdown of the Black Sea after the Younger Dryas, and they do not provide evidence for any catastrophic flooding of the Black Sea in the Early Holocene.In addition, available archaeological and paleoenvironmental evidence from the Pontic region reveal no recognizable changes in population dynamics between 14 and 6 ky BP that could be linked to an inundation of large magnitude [Dolukhanov, P., Shilik, K., 2006. Environment, sea-level changes, and human migrations in the northern Pontic area during late Pleistocene and Holocene times. In: Yanko-Hombach, V., Gilbert, A.S., Panin, N., Dolukhanov, P.M. (Eds.), The Black Sea Flood Question: Changes in Coastline, Climate, and Human Settlement. Springer, Dordrecht, pp. 297-318; Stanko, V.N., 2006. Fluctuations in the level of the Black Sea and Mesolithic settlement of the northern Pontic area. In: Yanko-Hombach, V., Gilbert, A.S., Panin, N., Dolukhanov, P.M. (Eds.), The Black Sea Flood Question: Changes in Coastline, Climate, and Human Settlement. Springer, Dordrecht, pp. 371-385]. More specifically, Mesolithic and early Neolithic archaeological data in southeastern Europe and Ukraine give no indications of shifts in human subsistence or other behavior at the time of the proposed catastrophic flood in the Early Holocene [Anthony, D., 2006. Pontic-Caspian Mesolithic and Early Neolithic societies at the time of the Black Sea Flood: A small audience and small effects. In: Yanko-Hombach, V., Gilbert, A.S., Panin, N., Dolukhanov, P.M.

Morphology and Development of Caves In the South-west of Western Australia, 1964, Bastian, L.

Caves in the coastal aeolian limestone of Western Australia show two major types of morphology due to different groundwater conditions. The first type comprises linear caves with streams, and develops on a watertable which has pronounced relief because of an undulating impervious substratum. Cave systems of this type are thought to start developing as soon as coherence begins to appear in unconsolidated dunes, and develop rapidly by collapse while the dunes are still weakly cemented, to assume more stable mature forms when the rock is strongly cemented.

Caves of the Coastal Areas of South Australia, 1965, Sexton, R. T.

The majority of South Australian caves occur in the Tertiary and Quaternary limestones of the coastal areas. Their distribution is discussed here on a geological rather than a geographical basis. The most significant caves are briefly described and illustrated to indicate different types and related developments in the coastal limestones. The most notable feature of the limestones is their soft, porous nature. Caves also occur in South Australia in hard, massively bedded Cambrian and Pre-Cambrian limestones and dolomites. These are not discussed in the present paper. To facilitate recording, South Australia has been divided into six zones as shown in Figure 1, and the caves numbered in order of discovery in each area. In general, both the name and the number of the cave have been given, but unnamed caves are specified by number only. The cave maps have been chosen to give as wide a coverage as possible of the various types, or to illustrate points of particular interest. The arrows on the section lines show the direction of viewing, and the sections are numbered to relate them to the plans. Where a cross-section and longitudinal section intersect, the common line has been drawn to relate the sections. The same scale has been used throughout for ease of comparison.

The geographical distribution of Australian cave dwelling Chiroptera., 1966, Hamiltonsmith E.
Of the 56 species of bats currently recorded from Australia, 22 are known to occur in caves. The geographical distribution of each of these species is detailed, and from this data, the species are divided into four groups according to their pattern of distribution. Group I comprises those species found only North of 18S latitude, all of which either also occur in New Guinea or are closely related to New Guinea species. Group II, including both endemic Australian genera, occurs over that area North of 28S latitude. This area largely comprises desert or semi-desert terrain, with its characteristics of low humidity and a wide range between extremes of temperature. Group III occurs in the Eastern Coastal Region, with one species extending to a limited degree along both Northern and Southern Coasts. Although temperature is extremely varied over this range, there are common environmental factors of moderate to high humidity and a moderate to low range of temperature variation. Group IV species are all widespread, in many cases over the whole continent, are all members of the Vespertilionidae, and occur in caves only occasionally or only in certain parts of their range. These species are more commonly found in trees or buildings. The possible factors contributing to the origin of these distributional patterns are discussed, and some areas for future investigation suggested.

Caves of Kiriwina, Trobriand Islands, Papua, 1968, Ollier C. D. , Holdsworth D. K.

The Trobriand group of coral islands is situated 100 miles off the northeast coast of Papua and north of the D'Entrecasteaux Islands. The largest island, Kiriwina, is 30 miles long and 12 miles across at its widest point. The authors visited Kiriwina for two separate periods of one week in 1967 and 1968 to undertake a phytochemical survey and a reconnaissance exploration of the caves. They believe that they explored all the sizeable caves from Wawela north. A DC-3 aircraft of Papuan Airlines operates a weekly flight between Port Moresby and Losuia, the Administration centre. Accommodation is provided on the island at the Trobriand Hotel, conducted by Mr. T. Ward, whose two trucks are used for local transportation on roads engineered by the US Army during World War II.

Olmec Cave Paintings: Discovery from Guerrero, Mexico, 1969, Grove David C. ,
A cave in Guerrero, Mexico, investigated in 1968, contained previously unreported Olmec paintings. These paintings, some of the oldest known in Mesoamerica, are stylistically similar to Olmec art from the site of LaVenta, on Mexico's Gulf Coast, but contain several important glyphic motifs never previously known to have existed at this time level. The iconography of the paintings confirms several important hypotheses concerning basic concepts of Olmec religion; the cave itself was probably a shrine to water and fertility. Several pre-Hispanic textile fragments found in the cave are probably from a later culture period

Caves of Vakuta, Trobriand Islands, Papua, 1969, Ollier C. D. , Holdsworth D. K

In a previous paper (1968a) we described caves of Kiriwina, the largest of the Trobriand Islands, a group of coral islands situated 100 miles off the north-east coast of Papua. This paper records caves of Vakuta, a smaller island south of Kiriwina. Vakuta is shaped like a boomerang (Figure 1) and is separated from the southern tip of Kiriwina by Kasilamaka Passage, about half a mile wide. The area of Vakuta Island is approximately 11 square miles. The island contains three villages, the most important being Vakuta Village which has a Methodist (now United Church) Mission. A track links Vakuta Village to Kasilamaka Passage which can be crossed by native canoe; the track continues on Kiriwina to Losuia, 40 miles north. Vakuta Island has a population of about 500. The Vakutans are of the same mixed Melanesian-Polynesian stock as the people of Kiriwina. Woodcarving is not practised to the same extent as in Kiriwina and the quality is generally low. However, some canoes have particularly well decorated prows. The influence of the Mission is very evident in the dress of the Vakutans and in the village, old cast-off clothing, often quite dirty, is the rule. In the fields the women wear grass and fibre skirts though the men were not seen to wear a pubic leaf as usual in Kiriwina, but shorts. Papuan Airlines operate a weekly flight between Port Moresby and Losuia, the Administration Centre, using Skyvan aircraft. Weekend tourist charter flights in DC-3 aircraft arrive frequently, but irregularly, from Port Moresby and occasionally from Lae and Rabual. The authors visited Vakuta Island in December, 1968. Guides were recruited locally and we were fortunate to be assisted by Mr. Gilbert Heers, the only European resident of the island, who speaks fluent Kiriwini which made communication with our guides relatively easy. With his help, we were able to obtain accounts of the legends and traditions associated with the caves on the island. We have also had valuable discussions about Vakuta and the customs and legends of the Trobriand Islands with Mr. Lepani Watson, M.H.A., who was born on Vakuta, and Mr. John Kasaipwalova, a Trobriand Islander now studying at the University of Queensland. We are most grateful for the assistance of these people. Although the most accurate map of the Trobriands is an Admiralty chart, the authors used an old U.S. Army map which was based on a pre-war Government survey. The caves were roughly surveyed using 100 ft tape, prismatic compass and abney level. The village rest-house became the social centre of the village during our stay. We had no difficulty in finding food. A surprising variety of foods such as yams, sweet potato, eggs, pineapples, soursop, tomatoes and fresh coconut appeared and payment was accepted eagerly in stick tobacco and newspaper. Payment in cash was rarely appreciated, though it will become more useful now that a trade store has been established by the Village Co-operative. To avoid repetitive explanations of features in the accounts of individual caves, various general topics will be discussed first.

Some Caves of Kitava, Trobriand Islands, Papua, 1971, Ollier C. D. , Holdsworth D. K

The Trobriand group of coral islands is situated 100 miles off the north-east coast of Papua, north of the D'Entrecasteaux Islands. Kitava, the most easterly island of the group, is approximately 4~ miles by 2~ miles. It is 15 miles east of Wawela on the main island of Kiriwina, though 50 miles by sea from Losuia around the north coast of Kiriwina. The population is approximately 2,000 natives, the majority being subsistence farmers and fishermen. No Europeans live on the island. Yams, taro, sweet potatoes and bananas are the main garden products. Fish, chickens and eggs are eaten, and pigs are used in ceremonial feasts or "sing-sings" . Kitava is served by occasional boats, but cannot be reached by air. The Administration boat, "The Pearl", is based at Losuia and calls at irregular intervals of a few weeks, the journey from Losuia taking about five hours. Kitavans travel far in their canoes, and the ceremonial Kula trade involves journeys to other Trobriand islands, the Amphletts, Dobu and the Woodlark Islands. The authors spent four days on Kitava in May, 1969, and lived in a native house near the village of Bomapou in the north of the island. Trade tobacco was used as currency to pay for food, and to pay guides and carriers. A trade store has since been established near the beach, a mile from the main village of Kumwageya, and payment in cash may be more acceptable in future. Children appreciate being paid in chewing gum, known throughout the islands as "P.K.". Very little English is spoken on the island and we were fortunate in having the company of Mr. Gilbert Heers who speaks the Kiriwinan language fluently.

Caves of Kitava and Tuma, Trobriand Islands, 1971, Ollier C. D. , Holdsworth D. K. , Heers G.

The Trobriand group of coral islands is situated a hundred miles off the north-east coast of Papua and north of the D 'Entr'ecasteaux Islands. In previous papers we have described caves on Kiriwina (the main island), Vakuta and Kitava (see References). We now describe caves of Kaileuna and Tuma (see Figures l and 2). In August 1970, we spent one week of intensive search for caves on these two islands, making our headquarters in the copra store in the village of Kadawaga. Kaileuna island is six miles long and almost four miles wide, and supports a population of 1,079 (1969 Census). It is separated from the large island of Kiriwina by a channel two miles wide between Mamamada Point and Boll Point, though the main village of Kadawaga on the west coast of Kaileuna is 18 miles from Losuia and 14 miles from Kaibola. The island is generally swampy in the centre with a rim of uplifted coral around the edge. We were assured that the correct name of the island is Laileula, but since Kaileuna is used on all previous maps it is retained here. However, we prefer Kadawaga to the Kudawaga or Kaduwaga that appear on some maps. The inhabitants are of mixed Melanesian-Polynesian Stock, who are almost totally self-supporting, being in the main farmers and fishermen. The yam (taitu) constitutes the staple crop and the harvest is still gathered in with ceremonies unchanged for centuries. There is great competition among families for the quantity and quality of the crop, which is displayed firstly in garden arbours (kalimonio), later in the village outside the houses; traditionally styled yam huts (bwaima) are then constructed to display the harvest until the next season. The transfer of yams from the garden to the village is occasion for a long procession of gatherers to parade through the village blowing conch shells and chanting traditional airs (sawili) to attract the attention of villagers to the harvesting party, After storage of the harvest, a period of dancing and feasting (milamala) continues for a month or more, Traditional clothing is the rule, Women and girls wear fibre skirts (doba), most of the men, especially the older ones, wear a pubic leaf (vivia) made from the sepal of the betel nut palm flower (Areca catechu Linn.). Tuma, the northernmost of the main islands in the Trobriand group, is six miles long and less than a mile wide. It is a low ridge of coral with swamps in the centre and along much of the western side. The island has been uninhabited since 1963 when the last few residents abandoned it and moved to Kiriwina, but it is still visited from time to time by other islanders who collect copra and fish. Tuma is believed by all Trobriand Islanders to be inhabited now by the spirits of the dead. It is also generally believed that Tuma is the original home of the TrobIiand ancestors; these ancestors are also said to have emerged at Labai Cave on Kiriwina Island, and from many other places of emergence or 'bwala". Lack of consistency in the legends does not appear to concern the Trobrianders very much. The cave maps in this paper are sketches based mainly on estimated dimensions, with a few actual measurements and compass bearings. Bwabwatu was surveyed more accurately, using a 100 ft steel reinforced tape and prismatic compass throughout.
