cruise diary, day 4: 19 Aug 2007

Left Rainier Dock on Columbia River early in the morning to sample 3 times in the Columbia River at Beaver Army Dock (station 6, casts 9, 10 and 11). Sediment sampling with Shipeck grab sampler. We then returned to the MERTS campus to install the new side-mount ADP. In the evening we sailed to the Maritime museum dock in Astoria to be closer to our sampling site the next morning in the South channel.
