DSTs: Logging your fishing gear!

The DST data loggers have been preferred by many scientists doing studies on fishing gear. Main advantages of the DSTs for these studies is the small size, selection of sensors, memory size, accuracy and reasonable cost. The loggers are used on various fishing gear, for example, nets, lines, trawl doors, pots and traps. The main objective is to monitor the performance of the gear, optimize fishing efficiency and minimize bycatch. Most popular parameter to record is the depth at different times, but other sensors of interest are temperature, salinity, tilt and compass direction of the gear.  Star-Oddi offers specially made housings both for protection against knocks and for giving more flexible mounting options. See our product overview.

Tilt measured in three directions!

The DST tilt is a small, versatile data storage tag ideal for various studies on underwater gear.
Scientists have chosen DSTs because they are less bulky and less expensive than other research equipment. The small size minimizes the influence on the behavior of the gear such as the sink rate.

In addition to measuring tilt in three directions (X, Y and Z) the logger also measures depth and temperature. The DST tilt can store 29000 measurements if all parameters are recorded simultaneously. Prior to its deployment, the DST tilt is programmed by the user with a selected sampling interval and start time.

After data collection, the data is retrieved into a PC computer using the Communication Box and SeaStar software where data is viewed in both graphic and tabular form. SeaStar also offers a variety of practical features such as a histogram which displays the data for each sensor within a specified time period enabling the user to view the data statistics in more detail. 

Star-Oddi offers Adjustable Housing for the DST loggers with tilt and magnetic field strength (compass) sensors. It can be attached to fishing gear as well as various underwater equipment. The design of the housing enables the user to easily and safely mount the logger to the subject as it can be either bolted or strapped.
The DST logger can be fixed inside the housing with a metal strap. This prevents the logger from rolling inside the housing which is important for the accuracy of the tilt measurements. The hard plastic housing also protects the logger from harsh knocks and other damage.

Graduation at the Trade Council Seminar

Representatives from 8 different companies, including Star-Oddi, took part in a year long export seminar held by the Trade Council of Iceland. Participating companies specialize in fields as varied as meteorology, jewellery design and knitting.

The seminar is held in collaboration with The New Business Venture Fund, The Federation of Icelandic Industries and The Icelandic Association of Women Entrepreneurs. It focuses on a development project intended for small and medium-sized companies that are either interested in entering a new market or wish to further strengthen their position within an existing market.

The graduation took place last April and we are pleased to announce that Ms. Maarit Kaipainen from Star-Oddi received a special acknowledgement for her project.

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:

Oil Spill Threatens Fragile Wildlife

The sinking of the Deepwater Horizon oil rig in the Gulf of Mexico has raised serious concerns for the diverse but fragile ecosystem that can be found in the surrounding areas. The rig, which is located about 50 km southeast of Venice, Louisiana, sank on April 22nd, two days after an explosion caused the death of 11 workers and left 17 injured.
Earlier reports stated that up to 5,000 barrels, about 795,000 litres, of crude oil had been leaking into the ocean every day since the accident. Those numbers are now considered to be much higher, even up to 70,000 barrels. Conservationists have also raised concerns about the additional effects that the chemical dispersants, used to steer the oil away from the coast, might have on the Gulf's wildlife. 

The Gulf of Mexico and its coasts are home to a variety of rare animals, many of them endangered. These include the bluefin tuna, several species of turtles and the brown pelican that was removed from the list of endangered species last year. The spill could cause serious health problems for many of the animals in addition to destroying their breeding and spawning grounds as many species migrate to the Gulf to breed in this period.
The spill could also have devastating effects on the Louisiana fisheries industry which is the second largest in the US. It is impossible to predict the damage that the spill might cause in the fishing grounds. Shortly after the accident, the US government established fishing, shrimping and oyster harvesting ban in an effort to guarantee food safety, leaving thousands of fishermen out of work. As of May 24th, the government has declared a "Fishery Disaster" in Louisiana, Mississippi and Alabama.
The British energy company BP, which was leasing the rig, has assumed full responsibility for the clean-up and has for the past few weeks tried to stop the leak. It has also announced that it will set up a $500million 10 year research program which will focus on studying the environmental effects of the oil and dispersants. The program will build on ongoing research programs that BP is conducting in the Gulf of Mexico.
