Laboratory on top of the Radiometer Van attending to scanning
5-mm and 14-um radiometers. These instruments slide to the end
of a 20-foot-long I-beam, well beyond the side of the ship, to
view undisturbed portside waters 25 feet below. Olympic gymnastic
hopefuls have used the beam to practice balance beam routines,
but they have not been seen since

Commentary:
We had 7 overflights by the Cessna today--7 circumnavigations of the
small triangle--at various altitudes up to 1.4 km. A New Zealand film
crew arrived by RHIB (small boat) from Nauru, together with the newest
member of our science party, Tony Reale of the National Oceanic Atmospheric
Administration's (NOAA's) National Environmental Satellite Data Information
System (NESDIS). Tony carried with him a "care package" from Boulder,
Colorado, via Ed Westwater, who remains on Nauru.
The RHIB crew returned with a good sunburn, despite using plenty of sun
screen. Overnight, the Ron Brown changed position slightly to fall just
outside territorial waters of Nauru, so we could launch radiosondes unencumbered
by coordination with Nauru airport. Through the heroic efforts of U.S.
Department of Energy's Clif Meyer on Nauru, Ann Weickmann on the Ron Brown
secured an Air Nauru ticket to return home July 5 -- not easy when most
credit cards are rejected, business is not conducted over the weekend,
and it is Friday, an unofficial, quasi-holiday!

Visual Observations:
It was another fair, shower-free day, much to the chagrin of radar hopefuls.
Brisk breezes have produced more whitecaps and a more exciting ride to
Nauru in the ship's small craft.
Instrument Status:
The Differential Absorption Lidar flashlamps were finally replaced and
its small telescope was realigned. All instruments continue to run well.
