Anti-Biofouling Copper Mesh for Salinity Loggers

To prevent biofouling on its salinity loggers, Star-Oddi now offers anti-biofouling copper mesh. The net is wrapped around the protective housing containing the logger, protecting the conductivity cells from bioufouling. The use of copper mesh is ideal for long term stationary monitoring.

Using Archival Tags to Study Atlantic Cod in the Gulf of Maine

Researchers from the School for Marine Science and Technology (SMAST) at the University of Massachusetts Dartmouth and the Massachusetts Division of Marine Fisheries have been using depth and water temperature data from Star-Oddi archival tags to study the seasonal movements, habitat occupancy, and stock structure of Atlantic cod in the Gulf of Maine. Results from their research were recently published in two articles.

Cod Seasonal Movements
The first, which was published in the ICES Journal of Marine Science, describes the seasonal movements and connectivity of a cod spawning component in the western Gulf of Maine. Their team combined data from multiple tag types, including Star-Oddi archival tags that were externally-attached or surgically-implanted, acoustic transmitters, and conventional tags. The use of multiple complementary tagging technologies permitted a more detailed description of cod seasonal movements than would have been possible if using only one of the technologies.

Improved Fish Geolocation
The second article, which was recently published in the Canadian Journal of Fisheries and Aquatic Sciences, includes the development and validation of an existing hidden Markov model framework for the geolocation of Atlantic cod in the Gulf of Maine using depth and water temperature data from archival tags. Their work included extensive validation using double-electronic-tagged fish (i.e., archival tag and acoustic transmitter), stationary archival tags, and simulated tracks. The modified geolocation approach yielded significant improvements and will be applicable to additional species and regions to obtain valuable movement information that is not typically available for demersal species.

Meet us at Oceanology International in San Diego, California 

Star-Oddi will be exhibiting at Oceanology International in San Diego, California on 14-16 February. If you are attending we welcome you to visit our booth no. B52. The event attracts over 2000 visitors from the industry, academia and government sectors.

Star-Oddi will display its range of small data loggers in the DST and Starmon series, including the newly released Starmon TD temperature and depth recorder.
The Icelandic Month Thorri 

Þorri, or Thorri, is the name of the fourth winter month in the old Icelandic calendar. The month starts on the Friday of the 13th week of winter which falls between January 19th-25th. The first day of Þorri is called Man's Day (Bóndadagur), on this day it is customary to give your husband or partner flowers. The favor is returned on Woman’s Day in the following month.

Today the month of Thorri is known for its celebrations, Thorrablot, which is a tradition that started towards the end of the 18th century. To celebrate Thorri people meet up to eat a selection of traditional Icelandic food, which includes rams testicles, boiled sheep's head and rotten shark. Of course all of this is washed down with the Icelandic snaps, Brennivín.
