Visual Observations: enerally overcast, but with multi-layered clouds and occasional sunlight. Whitecaps on 1-2 m waves.

Notable Events and Anecdotes: Several scientists are groggy today (sea sick). RHB lost a "drag race" with a freighter. Several flying fish were spotted. At night the DABUL lidar beam appears as green light column rising into the empty sky. Tonight we embark a pilot to guide RHB through Torres Straits (required by regulation). We are building an intranet system to post and share data and images. A series of informal seminars by Nauru99 investigators begins in two days and will occuring twice per week; the talks will be for both the ship's crew and the science party.

Instrument Status: All doing well, but not all are taking data due to salt spray.

Photometer
Pennsylvania State University's 7-channel stabilized sun photometer on 03 deck. Three times daily 3 other hand-held sun photometers are also used to take corroborating data.
