These data were collected on voyage 3 of the RSV Nuyina in the 2024/2025 season. The voyage was colloquially known as the "Denman Marine Voyage", as it operated in the vicinity of the Denman Glacier. Conductivity, Temperature and Depth (CTD) data were collected at various CTD stations throughout the voyage. Every time the CTD is ready to be deployed into the water and profile the water column, a folder is created under the name ‘cast_#’, where ‘#’ is a number. A number is assigned each time the CTD was turned on. There are a few instances when the CTD was turned on, but there was an issue, and the profiling did not occur. A number was still assigned and a cast folder created. Each ‘cast_#’ has several folders: docs, ladcp, proc and raw. - docs: ‘docs’ stands for ‘documents’. Here the logsheets with the information relevant to the CTD deployment, locations, time of cast, voyage name, depths at which Niskin bottles are fired, variables to be measured with the seawater collected at each bottle, and relevant information on toolbox, and rosette set-up are found. - ladcp: raw lower Acoustic doppler current profiler (ladcp) data - proc: ‘proc’ stands for ‘processed’ data. Raw data from SeaBird is shown in different formats and various snapshots of the data are also saved. o Hex: data format from Seabird911 o Other files from seabird: bl (information related to the firing of niskin bottles), and hdr and XMLCON (configuration files) o csv: same as above but in a format that can be read by text readers such as note app. Note that this is not the same as ‘processed data’ where the data goes through a series of steps and calibrations. o Cnv: this contains the data after the first data processing step according to Seasave software. It contains header with information on location, UTC time, and information on how the Seabird911 was configured, including the calibration coefficients of all the instruments.
