The centre was established in 2011 but until July 2013 it lacked a presidential decree specifying its duties, said centre head Mohammed al-Majaashi. The centre now seeks to expand the scope of its activities to include ensuring maritime safety in general, for example combating marine pollution and illegal immigration, and undertaking rescue operations. Al-Shorfa spoke with al-Majaashi about the centre’s activities, goals and importance. Al-Shorfa: What was the origin of the centre? Mohammed al-Majaashi: The centre was established pursuant to the resolutions of the Djibouti Code of Conduct on the Repression of Piracy and Armed Robbery against Ships in the Western Indian Ocean and the Gulf of Aden, signed by 20 countries in the region and approved by Yemen in 2009. One of the [Code's] articles stipulated establishing three information exchange centres — the first in Sanaa, the second in Mombasa, Kenya, and the third in Dar es-Salaam, Tanzania — with the Sanaa centre serving as a regional centre and the other two as national focal points. The Code also stipulated that signatory countries establish national communication nodes to relay information to and from the centre, and, of course, impart this information to the authorities in their countries. Yemen, Egypt, Jordan, Saudi Arabia, Sudan, Eritrea, Ethiopia, Djibouti, Somalia, Oman and the United Arab Emirates are all member states at the Sanaa centre. image - Mohammed al-Majaashi, head of the Regional Maritime Information Sharing Centre in Sanaa, scans video display boards at the centre. [Faisal Darem/Al-Shorfa] MUDUG governor of Puntland section has said that senior regional judiciary officials released pirates from prison after they have been paid bribes - Dalsan Radio. Mohamed Jaamac Tigey who was speaking with local media in Galkacyo has referred the insecurity in Mudug region and in the region’s capital of Galkacyo to the growing number of the pirates entering the town recently. The governor mentioned Galkacyo court officials recently released several pirate me who were released from the jail and then gang robbed a car from the north of Galkacyo. He has accused the court officials were corrupt and taking bribes from the pirates kings living in the region. FISHING vessel Naham 3 has been removed from the list of pirated ships as it is now grounded and unlikely to be moved again. Furthermore is it assessed that the remaining hostages have been moved ashore. Subsequently, the vessel has been removed from the list of vessels held by Somali pirates (NSC). THE semi-autonomous Somali state of Jubaland agreed Wednesday to ally itself with the national government, in a deal hailed as boosting to efforts to unify the war-torn nation - Capital FM News Kenya. The is welcome news for Somalia’s internationally-backed authorities, who have struggled to extend their reach far beyond the capital Mogadishu and are also fighting the Al-Qaeda-inspired Shabaab militia. Jubaland, situated in southern Somalia and bordering Kenya, was one of several breakaway regions of the fractured Horn of Africa nation. There is also Puntland in the northeast tip of the country which wants autonomy within a federation of states, while Somaliland in the northwest declared total independence in 1991. The agreement was signed after a week of negotiations in the Ethiopian capital Addis Ababa between Somalia’s state minister, Farah Sheikh Abdulkadir, and the self-appointed leader of Jubaland, Ahmed Madobe. “The Federal Government of Somalia and the (Jubaland) delegations have agreed to an Interim Administration” for the region, the agreement states. The deal will still see Madobe remain in charge of Jubaland for a two-year transitional period, but he did agree to hand over control of the port and airport in the strategic coastal city of Kismayo. THE Kenyan Ports Authority (KPA) says it has installed more than 400 Closed Circuit Television (CCTV) cameras as part of an electronic surveillance fence around the port of Mombasa as it moves to tighten security around ports nationwide - DefenceWeb. KPA managing director Gichiri Ndua told local media during a tour of the Mombasa facility that once commissioned, the new integrated security system will give the port 24-hour security surveillance and enable the KPA to deal with global maritime security problems such as smuggling and piracy and meet global port security standards. “We now have a state-of-the-art port security system in place which we shall officially commission soon. This puts our port under 24 hour (security) surveillance,” Ndua said. The system has been installed by Magal Security Systems, an Israeli company which specialises in maritime security and surveillance systems. The new system will also link all security and surveillance activities at Mombasa port automatically to the International Ship and Port Facility Security Code (ISPF-SC). Mombasa is one of East Africa’s busiest port and transit point for goods moving between Africa and Asia and from Asia to South America through the Horn of Africa. THE aim of this article is to find out about the modus operandi of Somali piracy during its most intensive period of activity: 2005-2011 - IEEE.es. The method used consists of the identification, matching and analysis of 19 categories for each one of the 1,190 incidents attributed to Somali pirates by diverse sources of official information. The results make it possible to demonstrate a general panorama of the pirate attacks and the way they have evolved, and another more specific one that reflects the diverse parts of the Indian Ocean in which they have taken place. The capability of Somali pirates to adapt in order to continue with their activity in the face of the measures carried out to repress them, and how they have become a threat to international security is highlighted and analysed. It is concluded that the methodology put forward has been useful and it can be used to analyse other modern maritime piracy phenomena and to carry out comparative studies. AS Somalia celebrates the first anniversary of the end of the transition, there is concern about the perceived slowdown in the fight against the Islamic militant group Al-Shabaab - AllAfrica. Andrews Atta-Asamoah has just returned from a visit to Somalia and says the security situation in Mogadishu is still precarious, even though a lot of progress has been made. He says the decision by the humanitarian organisation Médecins sans Frontières (MSF) to pull out of Somalia after 22 years in the country could be seen as a coded message to those who are considered to be too lenient towards Al-Shabaab. Piracy has drastically been reduced off the Somali coast. Are some of the punitive measures, like those against money laundering, finally working? All these responses are paying off, including the fact that ships now have their own security and are avoiding hotspots. One also has to give credit to the response of the Puntland government in trying to dismantle some of those groups who were behind the piracy, through imprisonment and legal responses. The underlying issue is that piracy is a fall-out of worsening insecurity in Somalia, so any time the security situation improves, you find that also reflected in the piracy situation. West Africa THE Commander, NNS Jubilee, Akwa Ibom, Commodore Isaac Ogbole, on Tuesday said the joint patrol teams of Nigerian Navy – NNS Jubilee and NNS Victory, Calabar, killed six pirates and injured one - Vanguard Nigeria. Ogbole said this in Ikot Abasi, Akwa Ibom while briefing newsmen on the activities of the command.

B. BABATUNDE, F. D. SIKOKI, M. C. ONOJAKE, R. U. AKPIRI AND D. AKPULOMA ABSTRACT A study of the concentrations of Ca, Mg, K, Zn, Pb, Cd, Co, Cr, Cu, Fe, Ni and Na in the sediment, sea water, fish and crab of the Bonny/New Calabar River Estuary in Niger Delta, Nigeria was carried out using atomic absorption spectrophotometer A-100 for two consecutive years. The contamination levels of the respective metals varied between 2011 and 2012and the range of mean values for all metals in mg/kg were presented along with variations at statistically significant level (P <0.05) between the two years studied. Only K, Zn and Co exhibited variation in their concentrations in water samples between the two years at a statistical significant level (P <0.05) probability. In sediment, only Cr varied between the two years at a statistically significant level (P = 0.05). All metals concentrations were higher in sediment than in water samples.Bioaccumulation factor (BF) indicated a more potent source of metals from sediment than water with organisms accumulating Zn, Fe and Ni in the magnitude of 10, 6 and 5 times more from sediment than from water. Some metals were more accumulated in fish than crab and vice versa.

  • Diatoms and Dinoflagellates of an Estuarine Creek in Lagos
    JournalSci. Res. Dev., 2005/2006, Vol. 10,73‐82 Diatoms and Dinoflagellates of an Estuarine Creek in Lagos. I.C. Onyema*, D.I. Nwankwo and T. Oduleye Department of Marine Sciences, University of Lagos, Akoka‐Yaba, Lagos, Nigeria. ABSTRACT The diatoms and dinoflagellates phytoplankton of an estuarine creek in Lagos was investigated at two stations between July and December, 2004. A total of 37 species centric diatom (18 species) pennate diatoms (12 species) and 7 species of dinoflagellates were recorded. Values of species diversity (1 ‐ 14), abundance (10 ‐ 800 individuals), species richness (0 ‐ 2.40) and Shannon and Weiner index (0 ‐ 2.8f) were higher in the wet period (July ‐ October) than the dry season (November ‐ December). These bio‐indices were higher in station A than Bfor most of the study period. Almost all the diatoms and dinoflagellates recorded for this investigation have been reported by earlier workers for the Lagos lagoon, associated tidal creeks and offshore Lagos. The source of recruitment of the lagoonal dinoflagellates is probably the adjacent sea as most reported species were warm water oceanic forms. Keywords: diatoms, dinoflagellates, plankton, hydrology, salinity. INTRODUCTION In Nigeria there are few studies on the diatoms and dinoflagellates of marine and coastal aquatic ecosystems. Some of these studies are Olaniyan (1957), Nwankwo (1990a), Nwankwo and Kasumu‐Iginla (1997), Nwankwo (1991) and Nwankwo (1997). Other works such as Chindah and Pudo (1991), Nwankwo (1986, 1996), Chindah (1998), Kadiri (1999), Onyema et al. (2003, 2007), Onyema (2007, 2008) have investigated phytoplankton assemblages and pointed out the dominance of diatoms. Diatoms and dinoflagellates are important components of the photosynthetic organisms that form the base of the aquatic food chain (Davis, 1955; Sverdrop et al., 2003).

  • Morphometric Parameters of the Calabar River Basin: Implication for Hydrologic Processes
    www.ccsenet.org/jgg Journal of Geography and Geology Vol. 2, No. 1; September 2010 Morphometric Parameters of the Calabar River Basin: Implication for Hydrologic Processes Eze Bassey Eze & Joel Efiong (Corresponding author) Department of Geography and Regional Planning University of Calabar, P. M. B. 1115, Calabar, Nigeria Tel: 234-803-273-8080 E-mail: [email protected] Abstract The study examined the morphometric parameters of the Calabar River Basin with emphasis on its implication for hydrologic processes. Data for this study were obtained from topographic map which were subject to field confirmation. The result revealed that the basin area was 1 514km2. There were 223 streams with a total stream length of 516.34km. The textural dissection was considered to be low as drainage density, stream frequency and drainage intensity values were 0.34km-1, 0.15km-1 and 0.05 respectively. The basin was found to be strongly elongated with circularity ratio of 0.34 and elongation ratio of 0.64. The average bifurcation ratio was 2.83. The very low value of drainage intensity implies that drainage density and stream frequency have very little effect on the extent to which the surface has been lowered by agents of denudation. These low values of drainage density, stream frequency and drainage intensity also imply that surface runoff is not quickly removed from the basin, making it susceptible to flooding, gully erosion and landslides, particularly in the lower part of the basin. It is therefore recommended that human activities that could impact negatively on stream network in the basin should be discouraged.

Published with open access at www.questjournals.org ABSTRACT: This paper was necessitated by the need to provide the platform for various geo-spatial analyses in the study area. The study investigated land use changes of a 30 year trend (1980 - 2010) using the Geographic Information System (GIS) analysis. Within the period, urban and farm land use types encroached on grassland, forest, bareland and waterbody by 17.54% and 13.59% respectively; reductions in grassland 12.01%, forest 11.01%, bareland 4.62% and waterbody 3.5%. The resultant is the generation of maps/charts of land use changes of the study area which reveals rapidly deforested region for urbanization and agricultural activities. This result will provide planners and decision makers a quick assessment of the potential impact of human activities and initiation of appropriate steps to minimize the action in the study area. Furthermore, it will yield valuable information for the analysis of the environmental impacts of population pressure, agriculture, urban expansion, resettlement programme, climate change, resources managers, development agents, fund providers, socio-economic development planners, public administrators and environmentalists because it has provided accurate information related to land use changes overtime.

EDEM, BARTH N. EKWUEME, BASSEY E. EPHRAIM AND EMMANUEL E. IGONOR (Received 22 July 2016; Revision Accepted 6 October 2016) ABSTRACT Stream sediments of Obudu Plateau were investigated with a view to elucidating their geochemical features, mineralization potentials and element concentrations. Stream sediment samples were collected from Southern Obudu Plateau area and analyzed for 22 elements, comprising major and trace elements, using Inductively Coupled Plasma – Mass Spectrometry (ICP-MS). The data obtained were statistically treated. Ba, Sr, Nb, Co, Pb, Ta and Na show moderate to high concentrations, when compared with threshold values of these elements. The concentrations of these elements in sediments of Southern Obudu show low mineralization potentials of pegmatites of the Obudu Plateau. The elements in Obudu stream sediments show perfect, strong, moderate and weak correlations among themselves, indicative of variations in their mobility. KEYWORDS: Correlation matrix, Major and Trace Elements, Stream sediments, Threshold. INTRODUCTION rocks (Rahaman,1988). The migmatite – gneiss is dominantly made up of quartzo – feldspathic gneiss that Stream sediment samples from major streams are predominantly biotite and / or hornblende – bearing and tributaries in Obudu area can be considered and rarely pyroxene (Ekwueme and Kroener, 2005; representative of upstream lithology.

  • GEOCHEMICAL MAPPING of METAL CONTAMINATION and DISTRIBUTION in TOPSOIL, WESTERN OBAN MASSIF SOUTHEASTERN NIGERIA Greg. U. Sikakw
    British Journal of Environmental Sciences Vol.6, No.4, pp. 41-57, December 2018 ___Published by European Centre for Research Training and Development UK (www.eajournals.org) GEOCHEMICAL MAPPING OF METAL CONTAMINATION AND DISTRIBUTION IN TOPSOIL, WESTERN OBAN MASSIF SOUTHEASTERN NIGERIA Greg. U. Sikakwe Department of Physics/Geology/Applied Geophysics, Faculty of Science, Federal University Ndufu-Alike Ikwo P. M. B 1010 Abakaliki Ebonyi State Nigeria ABSTRACT: This study is to examine heavy metal contamination of topsoil around the western flank of the Oban Massif and environs, southeastern Nigeria. Soil samples were collected in seven locations in farming and quarrying land use locations across the study area. Heavy metals (Al, Fe, Zn, Cu, Mn, V, Pb, As, Cr, Co, Ni, and Mo) were analyzed in soil samples using ICP-Ms. Computation of enrichment factor (EF) and Pollution index (PI) was performed on concentration values of potentially toxic heavy metals (Zn, Cu, Pb, As, Cr, Ni and Co), to determine the extent of pollution caused by human activities in topsoil of farming and quarrying areas. The concentration values of heavy metals in soils were also compared with world average background values of heavy metals. Results showed that the potentially toxic heavy metals enrichment factors and pollution index values were below values considered to be harmful to human health. The soil samples with respect to PI can be classified as deficient to minimal enrichment factor. With exception of Pb, Cr and Co which had PI values slightly above 1 and mean values exceeded 1, other potentially toxic heavy metals do not pose any health threat.

Twenty six genera of fish were identified belonging to 22 families consists of 22703 individuals collected from all the stations. The most dominant Correspondence: Paul J Udo, Fisheries and Aquaculture Unit, families were Clupeidae and Cichlidae with respective relative abundance of 17.69% and Institute of Oceanography, University of Calabar, Nigeria, 13.16% while the family Osteoglossidae was the least contributing only 0.77%to the fish Email taxa. For seasonal distribution, Mugilidae, Clariidae, Cichlidae, Gobiidae and Sciaenidae were abundant in both wet and dry seasons while Clupeidae, Bathyclupeidae, Carangidae Received: August 29, 2017 | Published: September 12, 2017 and Sphyraenidae were low in wet season but high in dry season. There was no significant seasonal difference (p>0.05) in fish biodiversity and abundance. Like other water bodies in the Niger Delta, the Cross River system was found to possess desired potential for fisheries exploitation considering its high fish species diversity, composition and abundance. Although pollution level was not measured in this study, the continuous discharge of wastes/ effluents into the aquatic ecosystem may pose deleterious effect on the biodiversity and abundance of the resident biota.

""111an III llllll 1mm «7111 mm] [In 931 SSSSSS ABSTRACT THE DECLINE OF THE CROSS RIVER AS A COMMERCIAL HIGHWAY IN SOUTH EASTERN NIGERIA BY Eyibl'o Grace‘Ekong The major purpose of this thesis is to examine the main causes of the decline of the Cross River waterway and its ports for commercial purposes in South Eastern Nigeria. Within this context, it is intended to determine whether the major factors underlying the decline of that waterway were purely physical and geographic or they were social and political. In other words, the aim of the study is to test and ascertain whether such causes were natural or man made, and also whether such causes were related or unrelated to the cause-and- effect conditions which generally follow developments in a developing and expanding region. The study first traces the historical development of the Cross River waterway and its ports in the wake of European contacts and international trade between West Africa and Europe and America dating back to the early 17th century. This area's prominence lasted well into the early 20th century.
