Slow Going
This morning at around 11:00 am we expected to be at our first rock
collection site. Due to heavy ice conditions, we made slower progress
through the night than anticipated, so we didn't reach our goal. We now
expect to reach the site at midnight. At that time, the first dredge will
occur.
Dredging is the process that we will use to collect the rocks from the
ocean floor over 3 miles down. A dredge is a large metal box that will
scrape across the ocean floor. It is lowered down by a piece of equipment
called a winch. When this process is happening, the ship stops. When the
dredge reaches the floor, the ship then slowly moves to pull the dredge
along. The ship then stops again and the winch is used to pull the dredge
back up, hopefully full of rocks. The rocks are then removed from the
dredge on the deck of the ship, brought into the labs, and cataloged. Then
analysis begins.
The scientists on this mission are most excited to pull up the first
dredge. Remember that these rocks are from the last unexplored, unstapled
mid-ocean ridge on the planet. Their value to research is immeasurable!
I continue to go outside on the ship often and gaze at the scenery. It is
hard to believe that I am so close to the North Pole. It is beautifully
stark here. I have been surprised at the "warm" temperatures, and often go
outside with a light jacket. I suspect that as we head into the fall
months this will change, so I am trying to enjoy it while it lasts.
Statistics:
* Latitude: 85 40 N
*Longitude: 18 45 E
*Temperature: 32 F
*Water temperature: 25 F
A scientist's job is never done. Here I am trying to get e-mails. No luck, so far! <>
