Particle beam attenuation coefficient (Cp) data from GEOTRACES carousel from R/V Knorr KN199-04, KN204-01 in the subtropical N. Atlantic Ocean, 2010-2011 (U.S. GEOTRACES NAT project)

<p>NOTE: Revised dataset was served on 5 Nov. 2013.</p> <p>Calibrated transmissometer data (particle beam attenuation coefficient, Cp) for the two deployed transmissometers (trace-metal clean Geotraces Carousel, GT-C; and the Ocean Data Facility conventional rosette, ODF, also known as the SIOR rosette). The transmissometers were WET Labs, Inc., 25 cm pathlength, C-Star transmissometer (660 nm). Traditional CTD readings (pressure, temp, sal, oxygen, depth) are reproduced here for convenience. Metadata for data other than Cp reported here should be consulted.</p>
