Daily Weather Forecast Mirai Updates! Nauru Updates!

Commentary:

Mainstream scientific observations ceased today at 0900. Before that we spent 16 hours characterizing the nocturnal aerosol plume downwind from Nauru at off-shore distances of 12, 9, 6, 4, and 2 km. Packing operations began in earnest at 0900, with the ship seeking calmer seas leeward of Nauru to facilitate numerous crane operations, until sunset. Two sets of RHIB (small boat) runs were made to exchange plaques and say our good-byes, and to allow a tour of the Ron Brown by Nauru High School seniors. Some scientists took the opportunity to have their laundry done on Nauru (rumor is that the ship may not allow laundry at all for the remainder of the cruise), but they almost regretted it when they could not convince the Chinese laundress (who understood ZERO English) to return the clothes wet and unironed in time for the last RHIB run. They ended up pulling the clothes themselves from the backyard drying racks and hastily making tracks for the RHIB. The native spelling of Nauru was given incorrectly yesterday. The correct native spelling is Naoero.

Tomorrow will be the final daily report from the Ronald H. Brown. We will be underway to Kwajalein.
