Hello everyone! This week I am writing from Lake Superior on board the R/V Blue Heron, which belongs to the University of Minnesota-Duluth. We are on a research cruise as part of a UNOLS chief scientist training course. The internet is very slow on board the ship so I will explain all of this next week and post some pictures.
Yesterday we arrived at our first sampling location near Duluth. We collected water column, sediment, and pore water samples. The sediments appear to show evidence of some well-documented dumping of waste from an iron ore processing facility close by. The dumping ended perhaps 30 years ago but there is a very prominent iron oxide layer near the top of the sediments. Today we are doing a multibeam bathymetric survey near Isle Royale for the geophysicist on board. This is my first time ever participating in this kind of data collection so I am learning a lot.
The lake is amazingly flat and calm this time of year. It is really helping us to get good data and good samples. And the crew on board is also fantastic. Really couldn't ask for more.
Have a great week!
