The Greenland Institute of Natural Resources (GINR) has purchased the Teledyne Marine SeaBat T50-ER extended-range multibeam sonar system for seafloor modeling in order to classify bottom types into habitats.
The SeaBat T50-ER multibeam sonar has enabled the institute to organize these bottom types into habitats to model the seafloor for undersea landform analysis or geomorphology.
Weather conditions often make it challenging to collect the necessary data. Ice and wind conditions, along with funding for ship time, can be obstacles to getting the data necessary for undersea landform analysis. That is where the SeaBat T50-ER multibeam sonar system comes in.
The SeaBat T50-ER is designed for swift mobilization on any survey vessel, securing minimal interfacing and low space requirements. It is the latest addition to the SeaBat T-series platform.
The highly compact and flexible rack-mounted sonar system with a built-in INS allows for fast mobilization, minimal interfacing, and extremely low space requirements.
Because the SeaBat T50-ER multibeam is fully frequency agile from 190 to 420 kHz, it allows for improved swath performance and reduced survey time under challenging acoustic conditions.
The GINR is continuing its research using the SeaBat T50-ER as one of the tools in its arsenal to monitor, manage, and advise Greenland’s Self-Government on climate change, the sustainability and biodiversity of its environment, and flora and fauna.
Seafloor terrain affects the distribution and diversity of fish populations and other animals. Effects of bottom types and geography have been reported in fish populations worldwide.
Seafloor mapping and landscape ecology analyses are essential in monitoring stock assessments and spawning sites.
The Teledyne Marine SeaBat T50-ER multibeam sonar system is a vital tool for understanding the geomorphology of undersea landforms to focus on monitoring commercial species, playing a significant role in the ongoing scientific documentation of population sizes. This monitoring is integral to the institute’s research.
Diana Krawczyk, Ph.D. Scientist, Greenland Climate Research Centre, said to Teledyne Marine; “Your multibeam has introduced a new opportunity of creating high-resolution habitat maps of the ocean seafloor around Greenland, thus filling major knowledge gaps and providing baseline information on the sea bottom for the vast number of end-users in Greenland, from fisheries management and environmental assessments to mining companies. Basically, we pioneered this field of research in Greenland. We are very happy about the SeaBat T50-ER! And we will surely make the best of it!”
