Sea-Bird Electronics CTDs were utilized during cruises conducted between March 2010 and April 2011 in Vieques Sound, Puerto Rico, Virgin Passage USVI, and the surrounding region. The recovered profile data are presented here in an ACII format.

In 2002 and 2003, the U.S. Geological Survey (USGS), Woods Hole Coastal and Marine Science Center (WHCMSC), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), conducted three exploration cruises (USGS Cruise 02051, NOAA RB0208, September 24 to 30, 2002; USGS Cruise 03008, NOAA RB0303, February 18 to March 7, 2003 and USGS Cruise 03032, NOAA RB0305, August 28 to September 4, 2003). These cruises mapped for the first time the morphology of this entire tectonic plate boundary stretching from the Dominican Republic in the west to the Lesser Antilles in the east, a distance of approximately 700 kilometers (430 miles). Observations from these three exploration cruises, coupled with computer modeling and published Global Positioning System (GPS) results and earthquake focal mechanisms have provided new information that is changing the evaluation of the seismic and tsunami hazard from this plate boundary. The observations collected during these cruises also contributed to the basic understanding of the mechanisms that govern plate tectonics, in this case, the creation of the island of Puerto Rico and the deep trench north of it. Results of the sea floor mapping have been an important component of the study of tsunami and earthquake hazards to the northeastern Caribbean and the U.S. Atlantic coast off the United States.

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2023_V04, titled: "International nutrient inter-comparison study in the Southern Ocean: quantifying and identifying the causes of differences in dissolved inorganic nutrient datasets between global seagoing laboratories - Phase 2". The voyage took place between June 5 and June 18, 2023 departing from Hobart (TAS) and returning to Hobart. Data for 10 CTD deployments were acquired using the Sea‐Bird SBE9+V2 CTD unit #24 (S/N 1332), fitted with 36 twelve‐litre bottles on the rosette sampler. Sea‐Bird‐supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO‐supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out‐of‐range values. The final conductivity calibration was based on a single deployment grouping. The final calibration from the secondary sensor had a standard deviation (SD) of 0.0010067 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1‐decibar binned averages were produced using data from the secondary sensors. The dissolved oxygen data calibration fit had a SD of 0.92376 μM. The agreement between the CTD and bottle data was good. The collected data were subsequently processed (quality-controlled), and archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC). Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2018_V01 titled: "Detecting Southern Ocean change from repeat hydrography, deep Argo and trace element biogeochemistry & CAPRICORN." The voyage took place from Hobart (TAS) to Hobart between January 10 and February 21, 2018. Data for 108 deployments were acquired using the Seabird SBE911 CTD 24, fitted with 36 twelve litre bottles on the rosette sampler. Seabird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. Seabird/CSIRO-supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out-of-range values. The final conductivity calibration was based on a single deployment grouping. The final calibration from the primary sensor for deployments 14-108 had a standard deviation (SD) of 0.0012686 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1 dbar binned averaged netCDF files were produced using data from the primary sensors. The dissolved oxygen data calibration fit for deployments 14-108 had a SD of 0.78897 µM and 0.78113 µM for the primary and secondary sensors respectively. The agreement between the CTD and bottle data was good. Altimeters (200m and 500m), Transmissometer, PAR, ECO Chlorophyll and ECO OBS (Optical Back-Scatter) sensors were also installed on the auxiliary A/D channels of the CTD. The collected data were subsequently processed and archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.

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.

Transects of near-surface seawater properties were collected over the fringing reef off Makua, HI, on the north shore of Kauai using a Conductivity-Temperature-Depth (CTD) logger, either hand-carried or mounted to a kayak. The instrument returns temperature, salinity as a function of depth, and latitude/longitude.

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2017_C01, titled: "GAB deep water geological and benthic ecology program". The voyage took place from 11 to 27th April, 2017 departing from Hobart and returning to Hobart (TAS). Data for 10 deployments were acquired using the Seabird SBE911 CTD 23, fitted with 25 twelve litre bottles on the rosette sampler. Deployments 3 – 5 were aborted due to electrical issues and the data for these casts will not be included in the processed data set. Sea-Bird and O&A calibration lab supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO -supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out-of-range values. The final conductivity calibration was based on a single deployment grouping. The final calibration from the primary sensor had a standard deviation (S.D) of 0.0029597 PSU, outside our target of ‘better than 0.002 PSU’. The standard product of 1dbar binned averaged were produced using data from the primary sensors. The dissolved oxygen data calibration fit had a S.D. of 1.0974uM. The agreement between the CTD and bottle data was good. Four fluorometers, a transmissometer and a Franatec CH4 sensor were also installed on the auxiliary A/D channels of the CTD. The collected data were subsequently processed and archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.
