DATE SET OVERVIEW:
This data set contains underway temperature, conductivity, depth, and pigment measurements conducted during the SNACS cruise, August ? September, 2005 and 2006 in the Chukchi and Beaufort Seas, off the coast of Barrow, Alaska. Each data set includes latitude/longitude position, decimal day, pressure (m), temperature (deg. C), conductivity (Siemens/m), salinity (psu), sigma-t, Beta660 values for backscatter, chlorophyll fluorescence (Engineering Units 1), and CDOM fluorescence (Engineering Units 2).

METHODS:
The Acrobat Model LTV-50X (Sea Sciences, Inc., Waltham, MA, USA)was towed behind the research vessel RV Annika Marie, undulating between the surface and 1-5 meters off the bottom, under computer control. Vessel speed was approximately 5 knots and the instrument lay-back varied between 50 and 150m from the transom. The instrument package included a Seabird SBE37, measuring conductivity, temperature, and depth and a Wetlabs Triplet Fluorometer, measuring particle backscatter at 660nm, chlorophyll (mg/m3), and CDOM (ug/L).
