Norway’s Institute of Marine Research brand new icebreaker research vessel is embarking upon a marine research expedition to Antarctica
The researchers will study the whole marine ecosystem, focusing particularly on krill. Led by the Institute of Marine Research, up to seven boats, including research and fishing vessels, will obtain data on the resources found in these rich waters.
“Norway is currently the country that takes the biggest krill catch in the Southern Ocean, so we have a responsibility to provide research and monitoring data to the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)”, explains Bjørn Krafft, who is leading the expedition.
This international survey for the CCAMLR aims to record the geographic distribution of the krill and obtain the data needed to update the population estimate for what is known as area 48. The latter area is where most of the krill fishery takes place.
During their 4,600 nautical mile-long journey taking in approximately 70 sampling stations, the researchers on the Kronprins Haakon will monitor and fish for krill. The previous large scale Antarctic expedition in the year 2000 sampled the same stations. In addition, the scientists will put satellite tags on seals and penguins on Deception Island and two other islands. This will help to understand the importance of the krill to the predators in the ecosystem and give an idea of the areas where they feed.
This information will be used to calculate where and how much it is safe to harvest without negative long term effects for the ecosystem.
The transit to Antarctica will also be used for separate research cruises. As it sails across the Atlantic, the Kronprins Haakon collected data on the sea bottom, currents and phytoplankton, which provide the basis for all marine life. In addition, researchers will use echo sounding to measure the total quantity of all organisms down to a depth of 750 metres. The mesopelagic species found there are currently a little-exploited resource.
The ship to return to Norway at the end of May.
