Trawling for Seabed Clues
For one aspect of the ICEBERGS project, the team is seeking invertebrates from the bottom of the sea to collect biological data. Using the Agassiz trawl, a large net with a curved metal frame, we scour the sea floor looking for our cold-water creatures. Sea stars, brittle stars, sea squirts, and more! We are after these creatures to study glacial retreat, from some of the most pristine ecosystems on the planet. We deploy the trawl over the back of the ship using the A-frame to target our catch. As the net disappears into the gloomy depths, we wait as the trawl scrapes along the bottom. Many scientists wait patiently for the net to return with a bounty of creatures.
