The international project on ocean CO2 sequestration CTD data report from the R/V "KOK" cruise 0599, 3-8 August, 1999

Abstract

Data from 31 CTD casts at 7 different stations (locations) on the SW side of the Hawaii Islands are presented. The data were sampled during a cruise with the UH research vessel "Ka´imikai-O-Kanaloa" from 3rd to 8th August, 1999. The cruise was part of an international project with participants from USA, Canada, Japan and Norway. The main purpose was to collect ambient data on the site where an experiment with injecting some CO2 into the deep ocean and studying the behaviour of the CO2 plume is planned to take place. The report describes the sampling program and the post-cruise work to calibrate and quality-control the data. It also includes some preliminary analyses of the CTD data, with emphasis on the water around 800 m depth which is the expected depth of injection of the CO2.
