11:30 a.m.:  Another beautiful day in Oregon's ocean waters.  Chief Scientist Jack Barth visited the bridge this morning to talk with the Bill Peterson, Chief Scientist on the New Horizon.  The Revelle is eastbound and the New Horizon is westbound on the same line.  Sometime this afternoon both ships will pass each other.

2:15 p.m.:  The Revelle made a Rendezvous with the New Horizon.  Both Chief Scientists were able to talk by radio and share information on sampling in this area.

The mammal and bird observers have posted their counts for August 1:  124 Pacific White Sided dolphins, 5 Dalls Porpoises, 11 Humpback whales, and 2 elephant seals.

The Acoustic Doppler Current Profiler (ADCP) is an instrument that provides valuable data to the GLOBEC research effort.  Steve Pierce is the scientist in charge of operating the instrument and working with the data.  Kasey Legaard, a graduate student from the University of Maine, is assisting with the ADCP as well as the HTI.  The data from the ADCP has been of interest since it was first introduced almost 20 years ago.  With the ADCP, scientists are able to more accurately measure and chart the surface and subsurface currents related to upwelling and downwelling.  The instrument works by bouncing sound waves off particles in the water and measuring the return echo.  By measuring the Doppler shift of the echoes and subtracting out the speed of the ship, the speed of the particles and therefore the speed of the water can be charted.  At the end of this cruise the profiles generated will be compared with other profiles gathered in this same study area.
