Muddy ice in Minas Basin

Jul 09, 13 Muddy ice in Minas Basin

Posted by in Atlantic, Bay of Fundy, CCGS Hudson

In June 2013, researchers from DFO (BIO), Dalhousie, and Acadia sailed on the CCGS Hudson to do some science. During the cruise, we deployed twelve sediment-laden ice blocks in Minas Basin to assess melt rates and observe drift. This work is part of a larger project aiming to survey the occurrence of sediment-laden and occasionally...

Filling the MUC with muck!

May 18, 13 Filling the MUC with muck!

Posted by in Instruments, Pacific, RV Sonne

Often times ocean scientists are interested in what’s happening below the water, on the ocean floor. One instrument used to sample deep-water ocean sediments is a Multi-Corer or MUC. What’s cool about a MUC is that it keeps the sediment-water interface intact. The ability of the MUC to preserve the most recent (top) sediment...

It’s always nice to “have” to go to sea in the tropics, especially when it’s 10 C and rainy back in Halifax. Dal MSc student Liz Kerrigan and her supervisor, Prof. Markus Kienast, are currently sailing aboard the 98 m German research vessel RV Sonne between Kaohsiung in Taiwan and Jayapura in the easternmost...

Sampling mud flats despite large tides!

Posted by in Bay of Fundy, Field work

You might have heard that the Bay of Fundy is home of the largest tides in the world, reaching heights above 16 m. As part of my Master’s project, I needed to obtain sediment cores from mud flats that experience such huge tides. Our usual hand coring technique consists of using a simple device to push plastic barrels into...
