DST bird - New Tag for Bird Migration Studies!

Star-Oddi introduces DST bird, the world's smallest archival tag measuring temperature and light intensity. The tag's dimensions are only 12mm x 6mm x 5mm and weighs 1.2 g. Despite the small size the memory can store 52,000 measurements in total, battery life is ca. 355 days, and data resolution is 10 bits (2 lux for light). All tags are calibrated for light and temperature, giving light accuracy better than +/-25 lux and temperature accuracy of +/-0.5°C.  Data is retrieved into the SeaStar software for further analysis.

The very small and lightweight tag opens up new possibilites for bird scientists to tag small species on which limited behavioral information exists. DST bird, which has already been taken into use by scientists, is expected to revolutionize understandings of the movements and habitat of small birds. The temperature and light information from the tags will help geolocate and find the migration route of the birds. Data from tags can be compared to existing weather data for different locations, indicating bird locations at different times, even for birds that migrate over a long distance.

Deep Ocean Tagging with UTE


Since 2003 the Marine Research Institute (MRI) of Iceland has been tagging and releasing redfish (Sebastes mentella) using the Underwater Tagging Equipment (UTE) from Star-Oddi. The MRI has so far conducted five underwater tagging cruises, with total release of 2758 tagged redfish, and current recapture rate of 52 fish (2%). The UTE is a unique technology that has enabled MRI‘s fish biologists to successfully tag redfish at great depths close to 1000 m and study the fish migration pattern.

The UTE is placed at the cod-end of a trawl and is remotely controlled onboard the vessel. Four underwater video cameras are placed inside the equipment for online monitoring and control of the tagging procedure. Video images and measurement data are transferred through the cable wire of the vessel. A small knife makes a tiny cut in the fish before the tag is pushed inside.

"The healthy condition of recaptured fish and no visible injuries from the tagging suggest that this technique of pushing the tags through a small cut is successful in preventing both tag shedding and permanent injury to the tagged fish", said MRI‘s fish biologist Thorsteinn Sigurdsson.

The UTE has proven to be the most effective way for tagging fish that do not survive being surfaced for tagging and release. See the release and recapture locations of the redfish around Iceland's exclusive economic zone (EEZ).

Data Storage Tags - DSTs

Star-Oddi has been manufacturing and developing DSTs since 1993. The data loggers are used for various studies, such as fish tagging, fishing gear studies and oceanography. You can find our whole product range here. The following sensors are available:

Deep-Sea Biology Symposium in Iceland

Star-Oddi exhibited at the 12th Deep Sea Biology Symposium which was held in Reykjavik from June 7-11. The symposium, which was hosted by the University of Iceland, was attended by over 250 participants from all over the world.
The symposium is one of the most important events among the deep-sea community and offers an ideal opportunity for scientists to get together and share their knowledge.
Apart from attending a variety of lectures, the participants were offered the chance to enjoy Icelandic nature as well as trying out an Icelandic delicacy, the fermented shark.

Viking Festival

 
Every year, hundreds of Vikings from Europe and America gather in the town of Hafnarfjordur to celebrate the annual Viking Solstice Festival. The Festival, which was first held in 1995, is the oldest and most important festival of its kind in Iceland.
A great emphasis is put on creating an authentic atmosphere and make visitors feel as if they have been transported back to the Viking age. The site is converted into a traditional marketplace where visitors get the chance to buy handmade crafts from the various artists who attend the Festival.
A variety of cultural events such as music and storytelling are also on offer, the biggest attractions are the staged battles where men dressed from head to toe in Viking attire, armed with swords and shields re-enact historic battles from the Viking age.
