The dataset consists of 173 CTD casts in Rhode Island and Block Island Sounds obtained during 4 surveys. The surveys were performed during 22-24 September 2009, 7-8 December 2009, 9-11 March 2010, and 16-18 June 2010. The casts cover the nearly the entire watercolumn from the surface to approximately 2 m above the bottom. The data were obtained with a SeaBird SBE19plus, which measures temperature, conductivity, pressure, optical backscatter, chlorophyll fluorescence, oxygen, and photosynthetically active radiation (PAR). All sensors were sampled at 4 Hz. The data were processed using the SeaBird data processing software suite, SBEDataProcessing-Win32. A low pass filter, with time constant of 1 s, was applied to the pressure record. Temperature and conductivity were low pass filtered with a 0.5 s filter time constant. To account for the relatively slower response of the temperature sensor, the temperature was advanced in time by 0.5 seconds relative to pressure. The oxygen voltage was advanced relative to pressure by 2 seconds for the September, December, and June survey casts and 5 seconds for the March survey casts. A correction for conductivity cell thermal mass effects was applied to the conductivity signal using the parameters recommended by SeaBird (alpha=0.04, 1/beta=8.0). A loop edit step was then applied, whereby portions of the cast in which the pressure was not changing sufficiently fast (0.1 dbar/s) were removed. This was followed by computation of salinity, sigma-t, and oxygen concentration. Finally, the data from the downcast were averaged into 1 dbar bins. Further details of the CTD data processing can be found in the header portion of the individual cast files. The final data files contain raw sensor values (1 dbar bin averages) plus a number of derived variables (e.g., salinity, sigma-t, oxygen). A full list of the output variables is contained in the header portion of the cast files.

This dataset comprises CTD data from R/V OCEANUS Cruise 34 Sept. 22 - Oct. 3 1977. These data were received from Dr. Carl Wunsch, Massachusetts Institute of Technology, via the CTD processing group at the Woods Hole Oceanographic Institution. Data has been processed by NODC to the NODC standard High-Resolution CTD/STD (F022) format. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.

Moored CTD profilers were deployed at two sites, Central and Eastern Long Island Sound. There were a total of 5 deployments. Three were at the Eastern site, in Fall 2002 (denoted "fa02es"), Spring 2003 ("sp03es"), and Fall 2003 ("fa03es"). Two were at the Central site, in Spring 2002 ("sp02cs") and Spring 2003 ("sp03cs"). The deployment durations ranged from about 2 weeks to about 10 weeks. The profilers were Brooke Ocean Technology Seahorse wave-driven technology, with a Seabird pumped CTD system (911 plus) and Model 43 oxygen sensor that collected profiles of temperature, salinity, and oxygen concentration as a function of pressure at 4Hz during free ascents nominally once per hour.

This dataset contains water conductivity and temperature casts collected by CTD from the research vessel Heron. Voltage profiles were measured by an optical backscatter probe deployed from research vessel Heron. ADCP instrument was deployed 30 m above the seabed, suspended from a fixed vessel (research vessel Strickland). The research vessel Strickland was moored (using 4 anchors) above the central submarine channel downstream of the Squamish delta. File Beamave_EA.txt contains the echo intensity averaged between four ADCP beams in counts. Echo intensity was used to derive the concentration of suspended sediment from 30 m to 60 m water depth, using an acoustic inversion method and physical samples for calibration. File vmag.txt contains the magnitude of velocity in m/s. These data were used to obtain the turbidity current measured on 15th June 2015. Data are in ASCII format.

Temperature profile and sound velocity data were collected using CTD, XCTD, and XBT casts in the Arctic Ocean, Mediterranean Sea - Eastern Basin, North Pacific Ocean, South Pacific Ocean, and Southern Oceans from April 11, 1975 to August 31, 1998. Data were collected by the US Naval Oceanographic Office as part of the Master Oceanographic Observation Data Set (MOODS) project.
