RV Investigator Voyage IN2017_v05 Hydrology Data

This record describes Hydrology (HYD) data collected collected from the Marine National Facility RV Investigator Voyage IN2017_V05, titled: Long-term recovery of trawled marine communities 25 years after the world’s largest adaptive management experiment. The voyage took place between October 11 and November 10, 2017 departing from Broome (WA) and arriving in Fremantle (WA).Hydrology samples were collected from Niskin bottles sampled at various depths during a Conductivity-Temperature-Depth (CTD) deployment. Parameters analysed were salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite and ammonium. Underway samples were also collected every 12 hours (or once every 24 if a CTD coincided with collection time) for nutrient analysis from the underway system which collects water from 7 m depth and is not filtered. This dataset has been archived at the CSIRO O&A Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset is contained in the Voyage Report and Data Processing Report.
