Oceanographic data and information initiatives in africa1

OCEANOGRAPHIC DATA AND INFORMATION INITIATIVES IN AFRICA

WHY NOT TALK ABOUT “AFRICAN DATA INITIATIVES?

Africa is so wide, having different political and economic groupings, each country doing “their own things”,

Data on/about/by Africa would cover many disciplines: natural sciences, engineering, technology, social sciences, etc

All Africa Data initiatives would need a separate “CONFERENCE”

OCEANOGRAPHIC DATA AND INFORMATION INITIATIVES IS APPROPRIATE


Earth and environmental data and information

  • The whole of Africa is surrounded by ocean, which is subjected to both natural and human phenomena

  • The dynamics of climate ( winds, temperature, barometric pressure, rainfall, etc.) and population affect the dynamics of the ocean.

  • The dynamics of the ocean (waves, currents, temperature, etc.) affect fisheries, transportation, exploration and exploitation of hydrocarbons and other economic activities

  • LME’s are important to African economies, e.g Benguela, Agulhas and Somali Currents

In 1998, African Countries embarked on“The African Process for the Co-operation for the Development and Protection of the Coastal and Marine Environment”

A Pan-AfricanConference on Sustainable Integrated Coastal Management (PACSICOM) was held in Maputo, Mozambique, in July 1998.

The Maputo Declaration recognised the need for further capacity building, especially the following:

Training and education in marine sciences and technology and their application to sustainable development;

Institutional strengthening; and

Sustainable funding.

“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 some initiatives

3.SOME INITIATIVES

  • 3.1Definition:

    Oceanographic data is divided into : Biological, Chemical, Geological, Physical, and Meteorology

  • 3.2There 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 other final disposition

3.2SOME INITIATIVES cont’d

(c) Topical & Operational Data Activities - Specially created activity centers that archive and provide data on specific regional or thematic topics, and newly established centers that provide processing and delivery of operational oceanographic products within operational oceanographic systems

Implementation review of status of network

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 gauges1

Djibouti, Djibouti


Other planned locations

Other planned locations

Pointe Noire, Congo (installation 30 March -6 April 2007)

Proposed location at the entrance to the port suitable radar or pressure gauge.


Limbe cameroon

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, 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 comoros

Moroni - Comoros

Northern 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

Alexandria - Egypt

New tide gauge to be located at NIOF


Dakar senegal

Dakar - Senegal

Repairs of tide gauge housing in progress


Morocco stations

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

Mtwara - Tanzania

Not among the original sites, but being considered – depending on availability of resources


Abidjan cote d ivoire
