1.1. INTRODUCTIONINTRODUCTION(a) The whole of Africa is
surrounded by ocean, which is subjected to both natural and human phenomena
(b) The dynamics of climate ( winds, temperature, barometric pressure, rainfall, etc.) and population affect the dynamics of the ocean.
(c) The dynamics of the ocean (waves, currents, temperature, etc.) affect fisheries, transportation, exploration and exploitation of hydrocarbons and other economic activities
(d) LME’s are important to African economies, e.g Benguela, Agulhas and Somali Currents

Integrated Coastal Management (PACSICOM) Integrated Coastal Management (PACSICOM) was held in Maputo, Mozambique, in July was held in Maputo, Mozambique, in July 1998. 1998.
The Maputo Declaration recognised the need for The Maputo Declaration recognised the need for further capacity building, especially the further capacity building, especially the following: following:
– Training and education in marine sciences and technology and their application to sustainable development;
“The African Process resulted in a Africa-wide Project, i.e. GOOS – AFRICA with the following priorities:
– Improved collection of In-Situ Ocean Measurements and Observations, Validation training and education in marine sciences and technology and their application to sustainable development;
– The collection and spatial analysis of satellite imagery of the coastal seas for fisheries resource management and coastal planning
– development of regional modelling and forecasting capabilities to provide additional protection against regular and extreme events.

3.3. SOME INITIATIVESSOME INITIATIVES• 3.1 Definition:
Oceanographic data is divided into : Biological, Chemical, Geological, Physical, and Meteorology
• 3.2 There are open access/managed data archives : Oceanographic Data Centres
(a) Intergovernmental Data Centers :
Established by international agreements to archive and manage and deal with multi-national datasets
(b) Research Project Data Centers
Data centers established by specific research projects to manage project datasets until final archiving at Intergovernmental Centers or

Products Development and Dissemination
Coastal Observing Systems In-situ measurements
upgrade and expand African network for in-situ measurements and monitoring of ocean variables (e.g. sea-level, temperature, salinity, currents, winds, etc)
[19 sea level stations installed/upgraded, 10 of them fitted with additional oceanographic sensors]
provide near real-time observations of ocean variables, and
building adequate capacity for collection, analysis and management of sea-state variables.

Implementation: Review of Status of Network.
About 40 installed stations, varying operational status, and quality of observations,
Initiatives by other regional initiatives and national institutions to install/upgrade tide gauges,
Indian Ocean Tsunami 26 December 2004, one of the worst marine disasters recorded impacted greatly on the implementation plan developed.
Installed Tide Gauges
Takoradi, Ghana
Nouakchott,Mauritania
Installed Tide Gauges
Djibouti, Djibouti
Other planned locations
Proposed location at the entrance to the port suitable radar or pressure gauge.
Pointe Noire, Congo (installation 30 March -6 April 2007)
Limbe - Cameroon
Limbe port - poor security and potential damage from old cargoes piled up on the very small jetty
Numerous passengers from ferries using the jetty.
SONARA Oil Refinery Jetty Provides best option-long, Secure, sufficient depth
Nosy Be, Fort Dauphin
Nosy Be the jetty has been destroyed and needs to be reconstructed
Port security is very limited. Strong swell within the harbour- pressure and radar sensor records difficult to process because of irregular variation in sea level.
Moroni - ComorosNorthern part of the new quay slowly sinking in water, south part not enough space and enough water to install the tide house and tide gauge well. Installation north of the island too difficult to realise; very shallow waters do not allow an installation alongside the coast.
The only solution would be to build offshore tide gauge huts far from the
coastline.
Alexandria - Egypt
New tide gauge to be located at NIOF
Dakar - Senegal
Repairs of tide gauge housing in progress
Morocco stations
Network exist of 9 operational tide gauges, most of them with acoustic sensors, proposal to install new at Casablanca.
Old tide gauge location, Casablanca
Mtwara - Tanzania
Not among the original sites, but being considered – depending on availability of resources
Abidjan – Cote d’ Ivoire
Configuration of tide gauges
Kalesto radar gauge; Two pressure sensors; Logosens-2 datalogger; OTT HDR DCP satellite transmitter for the Meteosat.
(Purchased and configured by Proudman Oceanographic Laboratory, United Kingdom).
Data Management further development and strengthening of
National Oceanographic Data Centres (NODC) to manage data streams from the coastal ocean observing network,
upgrading infrastructure in the NODC’s (including internet access and computer systems)

3.4.3 3.4.3 PLAN AND PROGRESSPLAN AND PROGRESS• Enhancing Human Resource Development
(HRD): – Recruitment of academic and scientific staff, e.g.
computer scientists and engineers to form a computer modelling group (www.theissresearch.org ).
– Organisation of training workshops– Reorganisation of the Institute into academic 3
departments (MBRM, CEMS and PAMS)• Identification of relevant models
The Institute, with funding from Sida-SAREC, has acquired the following computer modelling systems: ROMS, MATLAB, MIKE 21, SMS (ADCIRC) and ArcGIS. To enhance computing power, the Institute has acquired a powerful computer.
