Abstract

Hydrography and environmental conditions were measured with CTD at nine stations during R/V Endeavor cruise EN616 in July 2018. The stations ranged from the New England Continental Shelf, New England Continental Slope, to the Sargasso Sea ocean regions.

Discrete water sampling, depth profiles and CTD/Rosette Casts 
Hydrography and environmental conditions were measured with CTD at nine stations during R/V Endeavor cruise EN616 in July 2018.  Casts at each station included a CTD/rosette profile of temperature, salinity, dissolved oxygen and beam attenuation. 

At eight depths, three 10L Niskin samples were taken for discrete measurements of:​

1. Chlorophyll, nutrients including nitrate, nitrite, ammonium, phosphate, and silicate 
2. Particulate organic carbon (POC) plus particulate organic nitrogen (PON) 
3. Particulate inorganic carbon (PIC)
4. Biogenic silica
5. Birefringence counts of coccolithophores (done ashore) 
6. Shipboard Yokogawa Fluid Imaging Technologies FlowCam imaging cytometer, in order to enumerate the major microalgal classes and estimate the particle size distribution function

Measurements 1 to 4 are part of BCO-DMO dataset 837074 (See https://www.bco-dmo.org/dataset/837074, and the Related Datasets section below).
Measurement 5 of birefringence counts data is BCO-DMO dataset 887863 (See https://www.bco-dmo.org/dataset/887863, and the Related Datasets section below).
Measurement 6 is BCO-DMO dataset 887787.  (See https://www.bco-dmo.org/dataset/887787, and the Related Datasets section below)
