Daily Summary July 19, 2002, DOY = 200

At approximately 5:30 AM ET, after spending the night traversing Massachusetts Bay, the ship worked its way around Cape Ann and into the Gulf of Maine. The ship arrived off Star Island, one of the Isles of Shoals, at approximately 9:30 AM local time. The ship remained in this location until approximately 12:30 PM ET while there was an exchange of scientific staff with three members leaving and two new members arriving. The rest of the day was spent offshore in the vicinity of the Isles of Shoals. The air reaching the ship was clean throughout the day with elevated concentrations seen only for short periods when there was a ship upwind.

There was fog early and low clouds throughout the day. The winds at the surface were easterly throughout the period. However, during the late afternoon the data from the wind profiler and rawinsonds indicated that the winds were from the southeast just a few hundred meters aloft.

For all plots, time is indicated in GMT. Eastern time is -5 hours.
