PE13 27 CTD, N. Shelf and DeSoto Canyon, May 16-18, 2013

The main goals of this cruise were as follows: (1) Recover six moorings, including one sound source and three trawl resistant bottom mounts concentrated in the upper DeSoto Canyon. Instruments recovered have collected a year's worth of temperature, conductivity, pressure, and current data. (2) Occupy CTD stations at the mooring locations and along the western edge of DeSoto Canyon, collecting measurements of temperature, conductivity, pressure, dissolved oxygen, turbidity (amount of suspended particles in the water), optical properties of water (transmittance or attenuation of incident radiation), and chlorophyll-a. (3) Sample water from the western edge of DeSoto Canyon, up to and including mooring M6, in order to better understand the chlorophyll max. Collected samples will be analyzed for methane concentration, oxygen concentration, nutrients, cell microscopy, microbes (for DNA/RNA work) and particulate organic carbon (for carbon isotope work). (4) Acquire shipboard ADCP data (75kHz, 150kHz, and 300 kHz), from surface to bottom, for the duration of the cruise. This dataset contains CTD data from this cruise (R/V Pelican cruise PE13-27, sampled 2013-05-16 - 2013-05-18). Note that only temperature, depth, and salinity were exported from the hex files.
