Wow! What a busy day! We have been hopping from test to test. We have gathered zooplankton, benthos, and fish larvae. Additionally, we tested water samples from different depths. Using a rosette (water sampling machine) is a new experience for all. Our students routinely conduct tests on water, however we were able to utilize sophisticated electronic equipment to gather our data. We administered pH, alkalinity, hardness, and turbidity tests. It is great to see how these tests are performed by the scientists. It provides us with better information to share with our students back in the classroom. - Marie
We continued our sampling all day. We worked at 4 different stations on Lake Huron finding water quality, fish larva, plankton, and benthic organisms. At the last station before dinner we gathered a gill net that was set in the morning. We caught 2 walleye and a sucker.

The afternoon we studied larval fish. Once we used the key we found that you can find what type of fish it is by looking at anus placement and the number of myomeres (muscle segments before and after the anus). Yes we looked at a lot of fish butts but it was great to be able to identify the fish.
Tonight we will be putting into port at Tawas for the evening before moving into Saginaw Bay in the morning.


  1. Will you spend every night in a port? What are the living conditions like aboard ship? Also, how will the data you are collecting be used? ML

  2. Do you leave the ship when you get to port? Or stay on?

  3. We are a 24 hour working boat and we will not port one night. Tonight, we are anchored but we are off-shore, just close enough to see civilization. I share a stateroom with two other teachers. Some of the teachers onboard are sharing accomodations with the full-time crew or other scientists. The beds are twin-sized but comfy. The food is amazing. I am eating too much and not exercising. However, we are working hard and there IS an exercise room, if we feel inclined. Some of the data will be used by scientists from the University of Michigan. And, other data will be used in conjunction with projects that we teachers are developing (while onboard) to use back in our classrooms.
