2006 was the first year when MAREANO was fully operational. Mapping was conducted in the Tromsøflaket area.
In 2007 mapping with multibeam echo sounder and sampling geology and bottom fauna was continued in the Tromsøflaket area and started in Troms II and Nordland VII in accordance with set priorities.
In 2008 multibeam mapping and sampling of geology and bottom fauna was continued in the prioritised areas Troms II and Nordland VII. Habitat/biotope maps of Tromsøflaket were produced, and new data made available in WMS-format (e.g. maps of coral distribution, bottom fauna biomass, pollutants, biodiversity and dominating bottom fauna/biotops). Results were reported to the Monitoring group and ”Faglig Forum” for the Management Plan of the Barents Sea.
MAREANO in 2009
In 2009 multibeam mapping was completed in the prioritised areas The Egga shelf break and Troms III. Mapping of biology, geology and pollutants in the prioritised areas Troms II, Nordland VII and The Egga shelf break was also completed. Following maps were published at www.mareano.no:
- Geology of Tromsøflaket, Troms II, Nordland VII and The Egga shelf break.
- Habitat/biotopes for eastern part of Tromsøflaket.
- Topography maps for all areas covered with multibeam echo sounder and map of pollutants in samples collected in 2006-2008.
Results were reported to the Monitoring group and ”Faglig Forum” for the Barents Sea management plan.
Plans for 2010
2010 (april 2010):
- multibeam mapping in Troms III/Lopphavet, Nordland VI and a smaller area in the NE Barents Sea.
- Sampling biologi, geologi and pollutants in Troms III/Lopphavet and a smaller area in the NE Barents Sea. Areas in Nordland VI are not decided.
Mapping area
Total area is: 162 000 km2 including areas deeper than 1000 m.
Prioritised areas:
- The Egga shelf break
- Troms II
- Nordland VII
Areas mapped with mutibeam echo sounder:
- 2006: 4600 km2
- 2007: 13 000 km2 contracted and 5000 km2 delivered, areas not mapped are mapped in 2008 due to bad weather in the autumn
- 2008: 24316 km2 delivered, this includes 10 690 km2 planned and financed in 2007
- 2009: 13737 km2 delivered from the Eggakanten and Troms III
Areas mapped (sediment, bottom fauna and pollutants in sediments):
- 2006: total of 3200 km2, 2100 km2 on Tromsøflaket + 1100 km2 in Lopphavet (due to bad weather)
- 2007: total of 14000 km2, 4000 km2 on Tromsøflaket and 2000 km2 in Troms II (+ 1000 km2 in the Lyngenfjord due to bad weather) during a spring cruise. 7000 km2 in Troms II and Nordland VII during the autumn cruise.
- 2008: total of 18000 km2, 16000 km2 in Troms II and Nordland VII and 2000 km2 mapped inside the coast line.
- 2009: total of 16 000 km2 in Troms II, Nordland VII and on the Eggakanten. This is 80 % of the area planned 20 000 km2. In total 11 of 43 days were lost due to bad weather conditions and technical problems. Substantial challenge were connected to mapping in deep waters.
