Overview
Research conducted by the Greenland Institute of Natural Resources focuses on the living resources and environment in and around Greenland. They advise the government of Greenland and municipalities regarding the environment, flora and fauna, and climate change. The institute recently purchased the Teledyne Marine SeaBat T50-ER extended-range multibeam sonar system for seafloor modeling to classify bottom types into hab-itats. The SeaBat T50-ER multibeam sonar has enabled them to organize these bottom types into habitats to model the seafloor for undersea landform analysis or geomorphology. Seafloor terrain affects the distribution and diversity of fish populations and other animals. Ef-fects of bottom types and geography have been report-ed 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 geomor-
phology of undersea landforms to focus on monitoring commercial species. The SeaBat T50-ER plays a significant role in the ongoing scientific documentation of population sizes. For the Greenland Institute of Natural Resources, this monitoring is integral to the institute’s research.
The Challenge
The importance of seafloor modeling and the ongoing exploration to classify bottom types into habitats is far-reaching. Because the institute is responsible for this vital research contributing to Greenland’s economy, they acquired the SeaBat T50-ER multibeam sonar system to get the job done. Knowledge of annual fish and shrimp assessments is a critical part of the report submitted by the institute to the government of Greenland. Weather conditions often make it challenging to collect the nec-essary 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 Solution
The SeaBat T50-ER is designed for swift mobilization on any survey vessel, securing minimal interfacing and low space requirements. The SeaBat T50-ER is the latest addition to the world-leading 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 require-ments. 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 Greenland Institute of Natural Resources continues its research using the SeaBat T50-ER as one of the tools in its arsenal to monitor, manage, and advise Greenland’s Self-Government to promote the sustainability and biodiversity of its natural resources.
