EAF-Nansen Programme

Surveys

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 # 2018 Leg 3

Bay of Bengal Survey - Leg 3

Period: 23/06/2018 - 15/10/2018  (109 days)
Countries:
Bangladesh - Myanmar - Sri Lanka - Thailand
Objectives of the Surveys:

The surveys (including five legs 3.1 - 3.5) conducted in the Bay of Bengal had a broad ecosystem approach and aimed at gaining understanding of the ecosystem status in general, and of specific ecosystem components and attributes in particular. Opportunistic sampling addressing pollution was  carried out throughout all  survey’s legs.

  • Leg 3.1. started and ended in Colombo, Sri Lanka. This ecosystem survey researched demersal and pelagic  living resources on the shelf and slope , at the bottom depths from 20 m to up to 1000 m.
  • Leg 3.2 covered the Bay of Bengal ABNJ areas, with the aim to study the acoustic properties of mesopelagic fish and other mesopelagic organisms. During this leg, which started in Colombo (Sri Lanka) and ended in Chittagong (Bangladesh), samples for levels of nutrients and contaminants (incl. Microplastics) were collected.
  • Leg 3.3. This leg, with focus on surveying the waters of Bangladesh, aimed at mapping and assessing pelagic fish resources on the continental shelf.
  • Leg 3.4  The study of the Myanmar waters prioritised mapping and assessment of the fish resources ( both pelagic and demersal) on the continental shelf, with a special focus on distribution of mature fish as well as eggs and larvea in closed areas.
  • Leg 3.5. The final leg during this  regional survey took place in the Andaman Sea (Thailand). The main objective of the research was to cover demersal and mesopelagic reosurces and habitats at depths more than 100m.
Survey # 2018 Leg 2

Mascarene Bank Survey - Leg 2

Period: 04/05/2018 - 22/06/2018  (48 days)
Countries:
Mauritius - Seychelles - Sri Lanka
Objectives of the Surveys:

This survey (including two legs 2.1-2.2). The first leg of the research was focused on studying the Mascarene Plateau (Indian Ocean) - the geomorphology, benthic habitats and benthos, map the occurrence of fish and crustacean resources. The research team also looked into its oceanographic conditions, and recorded the occurrence of microplastics and marine debris.

The second leg was carried out to explore the distribution of mesopelagic fish vertically and horizontally, from the higher-oxygen regions of the southern Indian Ocean to the low-oxygen regions of the northern Indian Ocean. This survey studied the effect of the biogeochemical water properties on the distribution of mesopelagic fish, and monitored long-term changes in biogeochemistry since WOCE observations from 1995.

Survey # 2018 Leg 1

Ecosystem Survey East Africa - Leg 1

Period: 20/01/2018 - 03/05/2017  (97 days)
Countries:
Mauritius - Seychelles - Sri Lanka
Objectives of the Surveys:

This survey (including five legs 1.1-1.5) off East Africa had a broad ecosystem approach and aimed at gaining understanding of the ecosystem status in general, and of specific ecosystem components and attributes in particular.

Survey # 2017 Leg 3

Transboundary Pelagic Survey (South-Eastern Central Atlantic) - Leg 3

Period: 21/09/2017 - 17/12/2017  (80 days)
Countries:
Angola - Congo - Democratic Republic of the Congo - Namibia - South Africa
Objectives of the Surveys:

This survey (including four legs 3.1-3.4) addressed abundance and distribution of pelagic resources, environmental conditions within which they were found/appeared, and aspects of their early life history. The survey also offered an opportunity to sample and tackle other research topics of high regional and international interest.
