The R/V Dr. Fritjof Nansen is one of the principal tools for the EAF Nansen Project. The vessel, built in 1994, is dedicated to carry out resources and ecosystem surveys in partner countries in Africa, resulting in a strengthened knowledge base for the furtherance of EAF. Data collected from these surveys are used to gain knowledge on the elements of the marine ecosystem and to support management decisions. The R/V “Dr. Fritjof Nansen” is owned by the Norwegian Agency for Development Cooperation (NORAD), but is manned and operated by IMR, Bergen, Norway on behalf of the EAF-Nansen project.

The EAF-Nansen project supports partnership arrangements with other projects or programs with similar goals and objectives, with the aim to ensure a consistent and strengthened effort to achieve the goals of sustainable management of the fisheries and ecosystems in Africa.

The surveys under the EAF-Nansen project are therefore carried out in partnership and through costs sharing arrangements with other projects such as the LME projects around Africa. Access to the vessel and the cost to the partners are determined by a minimum set of conditions.

    The monitoring survey will hopefully enhanced the understanding of the nature and extend the knowledge of how the offshore oil activities can affect the marine ecosystem. This first survey will hopefully contribute with valuable information especially on the benthic communities and levels of contamination by hydrocarbons and heavy metals in the sediments.

    The Angolan Multisectoral Group of Experts has divided activities in two phases:  

    1. The first phase is to Elaboration the Angolan Environmental legislation for Monitoring of offshore oil activities. The Ministry of the Urbanism and Environment coordinates this activity with assistance from the Ministry of Petroleum and Ministry of the Fisheries. 
    2. The second phase is the Monitoring Strategies which is coordinated by the Ministry of Fisheries (National Institute of Fisheries Research).

    • Analysing the structure of the water column
    • Observing the influence of tides on the water masses immediately around each seamount
    • Analysing the relative biomass and movements of the deep-scattering layers and fish shoals on and off seamounts
    • Analysing samples of chlorophyll, phytoplankton and micro- and mesozooplankton taken with phytoplankton, bongo and multinets
    • Establishing the boundaries of the Agulhas-Somali Current Large Marine Ecosystem (ASCLME)
