DST BIRD
DST bird is a tiny geolocator intended for migration studies of birds. The data logger
measures and records light level and temperature.
All measured data is stored in the logger’s internal memory. When the logger isretrieved after the measuring period, recorded data is uploaded into the supporting
SeaStar software where it can be viewed and analyzed in graphic and tabular form.
Each measurement is displayed with its date and time. The same logger can bereused as long as the battery lasts.
The very small and lightweight logger opens up new possibilities for bird scientists
to tag smaller birds that little migration information exists on. With large amount of
temperature and light datapoints from loggers, the scientist is able to analyse birdmigration routes with approximate geolocation (latitude and longitude) at given dates
and times by comparing data from loggers to existing weather data collected byauthorities.
In order to use DST bird a communication box and SeaStar softwareis needed. The user sets the start time, start date and sampling interval
before starting the recorder. Sampling interval can be set in second(s),minute(s) and/or hour(s).
With default programming light and temperature are recorded at
the same time. It is possible to define different sampling intervals for the twoparameters. Data can be imported into more advanced software packages forgeolocation analysis, such as PatternFinder from Star-Oddi.

DATA STORAGE TAGS (DSTs)
Data Storage Tags have been manufactured and developed by Star-Oddi since1993. DST is a miniature underwater data logger available with different sensors
such as temperature, depth, salinity, tilt, magnetic field strength and acoustic
signals. The DSTs are used worldwide in research projects, including bird tagging
and environmental monitoring.

STAR-ODDI LTD.
Founded in Iceland in 1985, Star-Oddi has become recognized as oneof the world’s leading manufacturers of technology for research andindustrial use.
Since 1993, Star-Oddi has been manufacturing the Data Storage Tag(DST), a miniature data logger. DST’s are ideal for various types ofresearch where small reliable loggers are needed.

THE STORY BEHIND THE NAME:THE SAGA OF STAR-ODDI (STJÖRNU-ODDI)
Oddur Helgason lived and worked in Flatey, Skjalfanda, in northern
Iceland in the twelfth century. He was a hired labourer on a farm andstood out because of his outstanding knowledge. He used a lot of histime analyzing the movements of the sun, moon and stars resulting in
his nickname Star-Oddi.
Star-Oddi’s work is considered to be one of the greatest engineeringachievements of the Viking Age. His research enabled Vikings to sailover long distances and find their way back home. Scientists haveshown that he made remarkably exact observations, centuries aheadof his time.
