Morphometric features of the submarine slope of South-west part of Island Valaam

A digital bathymetric model with a spatial resolution of 10 × 10 m have been created based on measurements of bottom depths on the Southwest slope of the Island Valaam (Lake Ladoga) by sidescan sonar combined with geo-referenced system. Bottom inclinations were recognized with magnitudes up to 60° with rock structures with virtually no modern sediments. Scree and large boulders have been found, which can cause underwater noise when sliding down the steep slopes of Island Valaam.

In the summer of 1968 two prospectors from Nordisk Mineselskab NS examined a number of mineral indications on Wegener Halvø, which had been described by Eklund (1944). During the work they discovered that the bituminous Permian shales, the Posidonia shales, first found at this locality by Noe-Nygaard (1934), showed rather high contents of copper and lead minerals. At ten localities examined nine showed signs of mineralization (Lehnert-Thiel, personal communication, 1968) and it was therefore decided to make a detailed sampling profile the folIowing year. In 1969 four men, including the writer dug a 20 m long trench up to 1.6 m deep through the Posidonia shales in order to obtain fresh samples. The trench was situated about 550 m a.s.l. in the south-west part of the valley of Vimmelskaftet on Wegener Halvø (fig. 1). Under the Posidonia shales a stratum of reefy limestone forms a vertical wall 50-100 m high, and the shales themselves are covered by steep slopes of scree. In the trench, which ran from the reef upwards through the lowermost 16 m of the shales, a continuous 5 by 5 cm channel sample was excavated and divided in 39 parts corresponding to lithological units.

We studied in detail a moss-lichen component of Shokalsky Island vegetation for the first time and identified 79 species of mosses and 54 species and 2 subspecies of lichens and lichenicolous fungi. All species of mosses and 23 species and 2 subspecies of lichens and lichenicolous fungi are recorded for the first time for the island. The study is based on collections made in South West part of the island, in arctic tundra. We also explored the participation of the mosses and lichens in the main types of plant communities and the species distribution in 10 ecotopes. The paper describes the noteworthy findings (Abrothallus parmeliarum, Aongstroemia longipes, Arthonia peltigerea, Caloplaca caesiorufella, Catillaria stereocaulorum, Ceratodon heterophyllus, Lecanora leptacinella, Sphagnum concinnum, S. olafii) and features of bryo- and lichenoflora of Shokalsky Island.

Seasonal Population

Campecopea hirsuta (Montagu) occurs in rock crevices, and among barnacles and the lichen Lichina in south-west Britain. It is particularly abundant on shores ex-posed to wave action, occurring most commonly at about M.T.L. and below on shallow slopes, and from M.T.L. to H.W.N. on steep slopes. Young Campecopea of about 1–5 mm long are released in late summer. Females attain a maximum length of 35 mm and males 4–0 mm, each having a life span of no more than 1½ years.

Ophiolite complex in the west of Fanuj is 200 Km south west of Iranshahr in Sistan and Baluchestan province. This ophiolite complex lies in the uplift zone of the oceanic crust of Oman between Makran and Fanuj faults. Ophiolite of the west part of Fanuj is consisted of three parts including gabbro, diabase dikes and small quantity microdiorite masses. Ilmenite is the main mineral of titanium which along with magnetite has been formed independently or inter-crystalline way after crystallization of plagioclase, pyroxene and often along with amphibole in gabbro rocks. The formation of the broad gabbro masses which is associated with plagioclase and pyroxene crystallization in High Oxygen fugacity condition formed a fluid rich in iron and titanium during the formation of ferro gabbro rocks as the main host of the ilminite reserves. Gradual crystallization process and decrease in compatible elements such as Cr, Ni, Mg and increase in incompatible elements such as Mn، Na، Ti from the bottom to the upper parts of ophilite complex shows that the formation of the complex has been occurred through the process of crystal fractionation from a tholeiitic magma which is rich in titanium.

Lough Hyne

Preliminary observations of limpet activity at Lough Hyne, in south-west Ireland, showed that individuals on steep slopes were primarily active at night, when emersed; while those on near-horizontal rocks were often active during daytime submersion. Observations of limpet populations over an 11 d period of limpet populations on a near-vertical and a near-horizontal site, only 45 m apart, confirmed that animals on the near-vertical site were active on nocturnal low tides, whilst those on the near-horizontal site were active on daytime high waters. A short-term survey at ten sites, which had limpets on both extremes of slope (i.e. either near-vertical or near-horizontal), showed that limpets on near-horizontal surfaces were, on average, more active at daytime high waters than those on near-vertical faces. In 1996 and 1997 surveys of activity at daytime high, and nocturnal low waters were conducted at sites (14–15) with varying rock slopes (∼3–87°). In all cases, limpets on more steep slopes were active at nocturnal emersion whilst animals on more gentle slopes were active on daytime submersion periods. In most cases these trends were significant and explained between 22–40% and 37–44% of the variation in activity with site in 1996 and 1997 respectively. Analysis of the head orientation of limpets on their home scars showed that animals orientated in a down shore direction at all sites (1997 data) suggesting that limpets do perceive and respond to slope. Whilst slope does appear to influence the timing of limpets' activity (and especially on very steep or gently sloping sites) it does not account for a large degree of the variation in activity and, on sites with slopes between 30 and 60°, is likely to work in combination with other factors.

Abstract Sevan trout is an endemic fish species, registered in the Red Data Book of Armenian Animals as a ‘Critically Endangered’ species (IUCN category: CR A2cd) and is one of the most valuable fish of the Armenian ichthyofauna. For the purpose of preservation of this endangered fish species, rivers in the South-West part of Lake Sevan have been studied and their potential for spawning has been assessed through a relatively ‘cheap’ and ‘time-saving’ approach developed on the basis of hydrophysical, hydrochemical and hydrobiological studies. The results have shown that the highest potential to support natural reproduction of Sevan trout is in the middlestream part of Lichq river, as well as in the downstream part of Bakhtak river and the part of Bakhtak-Tsakqar system near the connection of the Bakhtak and Tsakqar rivers; however, all these areas need some remediation to achieve ‘high potential’.

Halangy Down (fig. 1) is the lower precipitous slope of the decline from Telegraph Hill (Ordnance Survey B.M. 166. 3 ft.) to the sea at Halangy Porth and Point. Halangy Down and the earlier chambered tomb upon the crest are often referred to locally as ‘Bants Carn’. The true ‘Bants Carn’ is a considerable rock outcrop dominating Halangy Point. This escarpment faces Crow Sound, which separates the north-west part of St. Mary's from the neighbouring island of Tresco. The hill-side is sheltered by the mass of Telegraph Hill from inclement weather from the north-east and east, but is fully exposed to the south-west and west.The existence of an ancient village site here has long been known in the islands. At the close of the last century, the late Alexander Gibson cleared away the underbrush from one of the more prominent huts and made a photographic record of its construction. Shortly after, the late G. Bonsor, of Mairena del Alcor, near Seville, in addition to excavating the chambered tomb, noted a considerable midden together with traces, of prehistoric occupation exposed in the cliffs of Halangy Porth just below the village site. Dr. H. O'Neill Hencken noted Bonsor's description of the midden, and, as nothing was known at the time of the material culture of the ‘village’, he associated the two.
