This dataset contains optical and physical data collected on R/V Knorr during cruise KN199-04 in the North Atlantic Ocean from 2010-10-16 to 2010-11-02. These data include absorption coefficient and depth. The instruments used to collect these data include Perkin Elmer Lambda 35 Spectrophotometer and Pump surface. These data were collected by Aimee Neeley and Joaquin Chaves of National Aeronautics and Space Administration as part of the "U.S. GEOTRACES North Atlantic Transect (U.S. GEOTRACES NAT)" project and "U.S. GEOTRACES (U.S. GEOTRACES)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-03-09.

The following is the text of the dataset description provided by BCO-DMO:

Spectral absorption coefficients of phytoplankton

Dataset Description:
Phytoplankton spectral absorption coefficient (ap) from surface samples collected on Whatman, 2.5cm glass fiber filters (GFF). Samples were collected during Geotraces 2010 (kn199-04).

The following metadata was extracted from the header information from each file. Where necessary the information was incorporated into BCO-DMO metadata fields or retained in file (* and X represent file-specific values):
