9/10/94

We are scheduled for a meeting at 12:30. We will be briefed on how to estimate snow and ice depths from the bridge. Each of us will have one or two "watches" during a 24 hour period while we're underway. Yesterday we had a brief meeting with Martin to clarify everyone's role on the ice. It won't be long now...we get underway @ 2100 hrs. Everyone is anxious to begin our adventure. Our week in Chile has been exciting and interesting, but the time has come to get busy and to do some science!

I'm feeling great today. I have made several email connections. Jane Stevens (free lance science journalist) and I got up early to work out in the gym, and then we went for a little run. I am enjoying rooming with Jane. She has written some arcticles about some very interesting subjects. What a great way to learn about nature!

This afternoon will be our last day in town. Everyone will be going out to pick up some last minute supplies (chocolate seems to be on the top of many persons' lists). I have become familiar with the ship. I have found a great observation spot...Martin said that it's OK to be up in the pilot house above the bridge. If I don't get seasick, I may use that as a perch...at least until it gets too cold!

Time for lunch!

Meeting for ice group re: estimation of ice/snow thickness while underway (cont.)

*SEE MANY HANDOUTS ON ICE TYPES, FLOE SIZES, TOPOGRAPHY, SNOW TYPE, ICE CONCENTRATION, SNOW & ICE THICKNESES, SAMPLE DATA SHEETS, SCHEDULE OF WATCHES

Important Announcement: "Sea Beam" trials are off (cancelled). This may mean that we could arrive in Auckland as late as October 22, and it could mean as many as 28 days in the ice!

Our snow and ice work on floes will be most extensive after we turn west. Oceanographers will get the priority as we travel the N-S transect. All of this will depend upon the ice/sea conditions!

The "Ice Obs." Program: The schedule will allow inexperienced people to work with experienced people at first. We will use what Martin termed "The Australian Method" (the data sheets were refined by the Aussies)

Purpose: Estimation of ice thickness over an area (which is significant to fluxes between the ice/ocean)

Estimates: Characterize the 3 thickest ice types (see notes on attached handouts). Also, complete the meteorological observations - see "weather channel" on TV monitor. In Addition: Iceberg observations-Use Radar screen range to estimate number and size.
