EAF-Nansen Programme


The EAF-Nansen Programme survey Timeline highlights the research (carried out by the R/V Dr Fridtjof Nansen. The aim of the Nansen scientific missions is to collect data and information on marine resources, habitats, environment and pollution in the surveyed countries. This knowledge will then help support developing countries in managing better their fisheries at regional and national level.

Navigate the timeline to learn more about the routes and legs of the surveys conducted by the R/V Dr Fridtjof Nansen from 2017 to 2022.

Details from each leg can be accessed by clicking on the Timeline posts, or in the full list below. 

Survey # 2019 Leg 4

Pelagic stocks and ecosystems Senegal – Morocco - Leg 4

Period: 26/09/2019 - 19/12/2019  (74 days)
Mauritania - Morocco - Senegal
Objectives of the Surveys:

This survey (including four legs 4.1-4.4) was conducted to provide a synoptic coverage of the main pelagic resources off Northwest Africa and of the oceanographic conditions in the area, and update the historic time series.

Survey # 2019 Leg 3

Transboundary survey - Western Gulf of Guinea - Leg 3

Period: 20/07/2019 - 25/09/2019  (74 days)
Côte d'Ivoire - Ghana - Guinea - Guinea-Bissau - Liberia - Sierra Leone
Objectives of the Surveys:

This survey (including two legs 3.1-3.2) was carried out to provide a synoptic coverage of the main pelagic and demersal resources in the Western Gulf of Guinea and of the oceanographic conditions in the area.

Survey # 2019 Leg 2

Transboundary demersal Survey - South-Eastern Atlantic - Leg 2

Period: 28/02/2019 - 16/07/2019  (118 days)
Congo - Gabon - Namibia - South Africa
Objectives of the Surveys:

This survey originally included six legs, with Kongo-Gabon survey (leg 2.6) that had to be replaced by an oceanographic transect across the Gulf of Guinea. Legs 2.1-2.5 was carried out to cover the demersal resources of the continental shelf and upper slope including distribution, abundance and biology of priority species and communities. The objective was also to collect biological samples of priority species, determine oceanographic conditions and map the map occurrence of microplastics and marine debris.

Leg 2.3 was a mesopelagic transect survey aimed to study acoustic properties of mesopelagic fish, biology and collect samples for future analysis of mesopelagic fish and jellyfish off the coast of Namibia.

Survey # 2019 Leg 1

ABNJ (Areas Beyond National Jurisdiction) Survey - Leg 1

Period: 24/01/2019 - 24/02/2019  (32 days)
Objectives of the Surveys:

All the study locations were located/situated in areas beyond national jurisdiction (ABNJ), within the Convention Area of the Southeast Atlantic Fisheries Organization  (SEAFO)

The survey started and ended in Cape Town, South Africa with the aim to cover the Discovery Seamount complexes including:

  • Geomorphology, benthic habitats and benthos;
  • Fish resources;
  • Physical, chemical and biological oceanography;
  • Debris (litter on the surface and seabed;
  • Microplastics;
  • Mesopelagic acoustic scattering layers en route
