From 1 - 10 / 13
  • Studies of the spatial and temporal variations of hydrophysical/hydrochemical parameters in the frame of the COMBINE Programme of HELCOM as well as measurements for the IOW's long term data set.

  • The monitoring cruise 10/10 in the Fehmarnbelt area from E Langeland to SE of Moen was scheduled from 11th October 2010 to 15th October 2010. Based on fortunate weather and working conditions the cruise program could be completed one day ahead of schedule. Some minor incidents happened during the cruise. These could be solved quickly but temporarily. Nevertheless it was a good and effective cruise.

  • The survey is part of the 1st quarter International Bottom Trawl Survey (IBTS) in the North Sea, which is coordinated by the ICES International Bottom Trawl Survey Working Group and has been conducted with standard fishing gear in the 1st quarter since 1983. The IBTS aims to provide ICES assessment and science groups with consistent and standardised data for examining spatial and temporal changes in (a) the distribution and relative abundance of fish and fish assemblages; and (b) of the biological parameters of commercial fish species for stock assessment purposes. The main objectives in the 1st quarter IBTS are to: • To determine the distribution and relative abundance of pre-recruits of the main commercial species (cod, haddock, whiting, Norway pout, saithe, herring, sprat, and mackerel) with a view of deriving recruitment indices; • To monitor changes in the stocks of commercial fish species independently of com-mercial fisheries data; • To monitor the distribution and relative abundance of all fish species and selected invertebrates; • To collect data for the determination of biological parameters for selected species; • To collect hydrographical and environmental information; • To determine the distribution of in particular herring and sprat larvae; The area to be covered by Denmark with RV Dana in the 1st quarter 2009 was allocated during the most recent IBTS Working Group meeting. Technical details are described in the current version of the survey manual (ICES 2006: IBTS Manual – Revision VII. http://datras.ices.dk/Documents/Manuals/. Additional sampling of fish eggs and larvae with a Bongo net was carried out according to the guidelines of ICES PGEGGS.i

  • Sampling of biological, physical and chemical data along standard transects in the Norwegian Sea.

  • The monitoring cruise 09/10 in the Fehmarnbelt area from E Langeland to SE of Moen was scheduled from 13th September 2010 to 17th September 2010. Upcoming strong wind from west / south-west caused an interruption of the cruise program on Tuesday morning, 14th September. The cruise ended in the harbor of Nakskov / Denmark. After one week of continuing strong winds, the cruise continued on Tuesday, 21st September from R?dby harbor. Thanks to good weather conditions, most of the missing transects and biological stations could be probed.

  • The main objective of the cruise was sample collection to contrain the development of hypoxia and anoxia in sediments and in the water column. Since all major Baltic Sea basins are permanently or periodically anoxic \nit is necessary to understand the effects e.g. in terms of cycling of nitrogen and phosphorus. Moreover the reaction of animals towards oxygen depletion living in the benthic environment is important to understand. Long and short sediment cores were taken and water column of the redoxcline was sampled in the Arkona, Landsort, Gotland Basins and in the Gdansk Deep.

  • The monitoring cruise 12/2010 in the Fehmarnbelt area from E Langeland to SE of Moen was scheduled from 13th December 2010 to 17th December 2010. Harsh wind and sea conditions forced a reduction of the monitoring program. Data sampling went on until Wednesday night, before finding shelter in R?dby harbor. A bad weather forecast resulted in ending the cruise earlier than schedulded, on Thursday morning.

  • The monitoring cruise 07/10 in the Fehmarnbelt area from E Langeland to SE of Moen was scheduled from 19th July 2010 to 23rd July 2010. The monitoring programme was worked off with no interruptions. Every station could be reached under good weather conditions. All sampling and data recording were completed. The co-operation between the crew, scientists and technicians on board of the vessel has been very good.

  • The monitoring cruise number 26JL1008 in the Femern Belt Area from E Langeland to SE of Moen was scheduled from 16th August 2010 to 20th August 2010. Due to bad weather conditions at the beginning it was not possible to start immediately after the whole equipment was set up on RV JHC Milj?. The scientific program had to be shortened and the cruise plan had to be adapted several times because of strong wind and high sea state. The ship?s crew and the scientific crew worked in a very good team together.

  • Environmental monitoring of the pelagic in the Gulf of Bothnia.
