Science and Technology Log
We successfully retrieved the 4 buoys in Amukta pass. Today we will pick up 2 of the 4 buoys in the Alaska stream and do before and after CTD readings. Normally we could do all 4 data points in a day but the ocean is so deep that it will take excessive time to do the CTDs. Tomorrow we will get the other 2 buoys and from there we have buoys in
Samulga pass and then into port in Dutch Harbor. Currently the predicted arrival is the night of the 21st.
Personal log
Last night we all tossed in our bunks looking forward to a bed that doesn’t move. So far I have been fortunate not to have sea sickness, but others have not been as fortunate.
Question of the Day: Describe the physiology of motion sickness including a detailed description of the inner ear. What is the structure of the inner ear that connects directly with the central nervous system? What are some possible causes of congenital deafness, what new technologies are being used to treat deafness and what defects can be treated with these technologies?
