Life on Kosterhavet’s seabed analysed

14.12.2011
Kosterhavet National Park was created to provide a haven for both protected species and nature lovers. Now researchers at the University of Gothenburg have analysed species living on the seabed (benthic species) in the marine national park to determine which marine areas require special protection.
“It’s not possible to survey each square meter manually in the national park. That’s why I’ve done what experienced mushroom pickers do when they’re looking for chanterelles. I’ve studied what the seabed should look like in order for different benthic animals to thrive, so that we can predict where certain species might be living,” says Genoveva Gonzalez Mirelis at the Department of Marine Ecology at the University of Gothenburg.

2 million map tiles
To be able to predict where different kinds of benthic species are in Kosterhavet using computer models based on knowledge of deepsea and seabed conditions, Genoveva Gonzalez Mirelis began by dividing up the entire seabed in the national park into 15 x 15 metre squares. This gave her basic data comprising more than two million map tiles, which were divided up into different types of seabed.

Using a geographical information system, GIS, she then produced a map of the occurrence of nine different types of benthic communities in Kosterhavet, including communities that were dominated by deepwater corals and Norway lobster. The method developed by Genoveva Gonzalez Mirelis can also be used to analyse other marine areas.

Basic data for marine planning

In order to preserve environments and species for future generations there are special regulations within Kosterhavet National Park, for example as regards anchorage and trawling. Good management requires a marine plan that clarifies which interests have priority in different areas, which is why different regulations are needed for each zone in the park. New legislation for marine planning is expected to come into force during 2012.

“I hope that my results can contribute towards the future management of Kosterhavet National Park, so that we can continue to enjoy Koster prawns with a clear conscience for the foreseeable future.”

The thesis Spatial distribution and conservation planning of seabed biological diversity was successfully defended at the University of Gothenburg on 9 December.

In this video you can see a selection of images from stony seabeds in the Kosterfjord area, with species such as the soft corals Dead Man's Finger (Alcyonium digitatum) and Swiftia rosea, the peacock worm Sabella pavonina, the Geodia barretti sponge, the bivalve clam Acesta excavata, deepsea anemones such as Urticina Eques and Bolocera tuediae, and the king crab (Lithodes maja).
The other half of the film shows images of deepsea coral colonies in the area Säcken; including the coral Lophelia pertusa, which lives jointly with the Mycale Lingua sponge, and the sea lily Hathrometra sarsii, which you can see swimming with its five arms.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
