Conductivity, temperature, and depth (CTD) data collected on the research vessel Sikuliaq, Northeast Chukchi and Western Beaufort Seas, 2016
The Conductivity, temperature, and depth ((CTD) )data archived here were collected during a 2016 research cruise on the Research Vessel (R/V) Sikuliaq (SKQ201612S). The cruise departed Nome September 3, 2016 and returned Sept 25, 2016. CTD stations were occupied throughout the NE Chukchi and Western...
