GEOTHERMAL RESOURCE INDICATIONS OF THE GEOLOGIC DEVELOPMENT AND HYDROTHERMAL ACTIVITIES OF D.R.C. Getahun Demissie Addis Abeba, Ethiopia, [email protected] ABSTRACT Published sources report the occurrence of more than 135 thermal springs in D.R.C. All occur in the eastern part of the country, in association with the Western rift and the associated rifted and faulted terrains lying to its west. Limited information was available on the characteristics of the thermal features and the natural conditions under which they occur. Literature study of the regional distribution of these features and of the few relatively better known thermal spring areas, coupled with the evaluation of the gross geologic conditions yielded encouraging results. The occurrence of the anomalously large number of thermal springs is attributed to the prevalence of abnormally high temperature conditions in the upper crust induced by a particularly high standing region of anomalously hot asthenosphere. Among the 29 thermal springs the locations of which could be determined, eight higher temperature features which occur in six geologic environments were found to warrant further investigation. The thermal springs occur in all geologic terrains. Thermal fluid ascent from depth is generally influenced by faulting while its emergence at the surface is controlled by the near-surface hydrology. These factors allow the adoption of simple hydrothermal fluid circulation models which can guide exploration. Field observations and thermal water sampling for chemical analyses are recommended for acquiring the data which will allow the selection of the most promising prospects for detailed, integrated multidisciplinary exploration. An order of priorities is suggested based on economic and technical criteria. -
ENERGY COUNTRY REVIEW Sudan
ENERGY COUNTRY REVIEW Sudan keyfactsenergy.com KEYFACTS Energy Country Review Sudan Most of Sudan's and South Sudan's proved reserves of oil and natural gas are located in the Muglad and Melut Basins, which extend into both countries. Natural gas associated with oil production is flared or reinjected into wells to improve oil output rates. Neither country currently produces or consumes dry natural gas. In Sudan, the Ministry of Finance and National Economy (MOFNE) regulates domestic refining operations and oil imports. The Sudanese Petroleum Corporation (SPC), an arm of the Ministry of Petroleum, is responsible for exploration, production, and distribution of crude oil and petroleum products in accordance with regulations set by the MOFNE. The SPC purchases crude oil at a subsidized cost from MOFNE and the China National Petroleum Corporation (CNPC). The Sudan National Petroleum Corporation (Sudapet) is the national oil company in Sudan. History Sudan (the Republic of the Sudan) is bordered by Egypt (north), the Red Sea, Eritrea, and Ethiopia (east), South Sudan (south), the Central African Republic (southwest), Chad (west) and Libya (northwest). People lived in the Nile valley over 10,000 years ago. Rule by Egypt was replaced by the Nubian Kingdom of Kush in 1700 BC, persisting until 400 AD when Sudan became an outpost of the Byzantine empire.

African Shads, with Emphasis on the West African Shad Ethmalosa Fimbriata
American Fisheries Society Symposium 35:27-48, 2003 © 2003 by the American Fisheries Society African Shads, with Emphasis on the West African Shad Ethmalosa fimbriata EMMANUEL CHARLES-DOMINIQUE1 AND JEAN-JACQUES ALBARET Institut de Recherche pour le Deoeioppement, 213 rue Lafayette, 75480, Paris Cedex 10, France Abstract.-Four shad species are found in Africa: twaite shad Alosa fallax and allis shad A. alosa (also known as allice shad), whose populations in North Africa can be regarded as relics; West African shad Ethmalosa [imbriata (also known as bonga), an abundant tropical West African species; and kelee shad Hi/sa kelee, a very widely distributed species present from East Africa to the Western Pacific. Ethmalosa fimbriata has been the most studied species in this area. The concentrations of E. fimbriata are found only in estuarine waters of three types: inland, coastal, and lagoon estuaries. The species is rare in other habitats. Distribution thus appears fragmented, with possible exchanges between adjacent areas. In all populations, juveniles, subadults, and mature adults have different habitat preferences. These groups are distinguished by local people and can be considered as ecophases. The older group has a preference for the marine environment, and the intermediate one is more adapted to estuaries, with a large plasticity within its reproductive features. Information regarding population dynamics is poorly documented, but the populations appear generally resilient except when the estuarine environment deteriorates. West African shad has been exploited for many years and carries great cultural value for the coastal people of West Africa. The catches are marketed cured in the coastal zone, sometimes far from the fishing areas. -

Context New Displacements
SUDAN Figure Analysis – Displacement Related to Conflict and Violence CONTEXT Conflict worsened in Sudan in 2018, with renewed fighting in the Jebel Marrah mountains on the borders of South, North and Central Darfur. Clashes between the government and local armed factions regularly broke out in this area, and in 2018 the number of new displacements nearly tripled compared to 2017, rising to 41,000. Conflict-induced displacements were also recorded in South Kordofan due to clashes between the Sudanese army and the local armed groups. People also returned home in 2018, mostly to the five states in Darfur. About 5,600 people reportedly returned through the country, though it is unclear how sustainable these returns are because new settlers have attacked returning IDPs on several occasions. The Sudanese government has also decided to convert several IDP camps into residential areas.12 The outcomes of these initiatives remain to be seen.

Other Processes Regulating Ecosystem Productivity and Fish Production in the Western Indian Ocean Andrew Bakun, Claude Ray, and Salvador Lluch-Cota
CoaStalUpwellinO' and Other Processes Regulating Ecosystem Productivity and Fish Production in the Western Indian Ocean Andrew Bakun, Claude Ray, and Salvador Lluch-Cota Abstract /1 Theseasonal intensity of wind-induced coastal upwelling in the western Indian Ocean is investigated. The upwelling off Northeast Somalia stands out as the dominant upwelling feature in the region, producing by far the strongest seasonal upwelling pulse that exists as a; regular feature in any ocean on our planet. It is surmised that the productive pelagic fish habitat off Southwest India may owe its particularly favorable attributes to coastal trapped wave propagation originating in a region of very strong wind-driven offshore trans port near the southern extremity of the Indian Subcontinent. Effects of relatively mild austral summer upwelling that occurs in certain coastal ecosystems of the southern hemi sphere may be suppressed by the effects of intense onshore transport impacting these areas during the opposite (SW Monsoon) period. An explanation for the extreme paucity of fish landings, as well as for the unusually high production of oceanic (tuna) fisheries relative to coastal fisheries, is sought in the extremely dissipative nature of the physical systems of the region. In this respect, it appears that the Gulf of Aden and some areas within the Mozambique Channel could act as important retention areas and sources of i "see6stock" for maintenance of the function and dillersitv of the lamer reoional biolooical , !I ecosystems. 103 104 large Marine EcosySlIlms ofthe Indian Ocean - .

Little Fish, Big Impact: Managing a Crucial Link in Ocean Food Webs
little fish BIG IMPACT Managing a crucial link in ocean food webs A report from the Lenfest Forage Fish Task Force The Lenfest Ocean Program invests in scientific research on the environmental, economic, and social impacts of fishing, fisheries management, and aquaculture. Supported research projects result in peer-reviewed publications in leading scientific journals. The Program works with the scientists to ensure that research results are delivered effectively to decision makers and the public, who can take action based on the findings. The program was established in 2004 by the Lenfest Foundation and is managed by the Pew Charitable Trusts (www.lenfestocean.org, Twitter handle: @LenfestOcean). The Institute for Ocean Conservation Science (IOCS) is part of the Stony Brook University School of Marine and Atmospheric Sciences. It is dedicated to advancing ocean conservation through science. IOCS conducts world-class scientific research that increases knowledge about critical threats to oceans and their inhabitants, provides the foundation for smarter ocean policy, and establishes new frameworks for improved ocean conservation.
