This dataset contains CTD casts and salinity water samples taken from research vessel Endeavor (cruise EN573) from 2016-01-26 to 2016-02-11. A number of moored platforms for the Northwest Tropical Atlantic Station (NTAS) and Meridional Overturning Variability Experiment (MOVE) projects were serviced during the cruise. These data were used to calibrate and validate the mooring data. The CTD salinity data have been quality-controlled and adjusted using the water sample data. The raw CTD data files are already available through the Rolling Deck to Repository (R2R) program under https://doi.org/10.7284/122113. Data are in NetCDF format.

This dataset contains CTD profiles from cruise PC-18-03 by NOAA Ship Pisces in 2018. It had the objective to service a number of moored platforms for the NTAS and MOVE projects (Northwest Tropical Atlantic Station and Meridional Overturning Variability Experiment, resp.). To calibrate and validate the mooring data, CTD casts with salinity and oxygen water samples were collected. The CTD sensor data have been quality-controlled and adjusted using the water sample data. The raw CTD data files are already available through the NOAA Rolling Deck to Repository (NOAA R2R) program at the NOAA National Centers for Environmental Information under accession number 0176413. Data are in netCDF.

This dataset contains salinity-calibrated Conductivity Temperature Depth (CTD) and bottle data from the 2021 Ocean Observatories Initiative (OOI) Irminger Sea 8 cruise of the research vessel Neil Armstrong (AR60-01). Data quality control methods have been used to assess performance of the CTD instrument. Resulting high-quality profiles were then used together with salinity bottle data analyzed at sea to create a post-cruise salinity-calibrated CTD product. This submission has been produced as part of an ongoing effort to more fully utilize CTD data collected by OOI Irminger cruises, which have been taking place annually since 2014. The hydrographic data collection facilitated by OOI in the Irminger Sea currently supports science for not only OOI end users, but also international oceanographic research projects, including the Overturning in the Subpolar North Atlantic Program (https://www.o-snap.org/), Atlantic Meridional Overturning Circulation Program (https://usclivar.org/amoc) and BioGeoChemical Array for Real-time Geostrophic Oceanography program (https://biogeochemical-argo.org). Such programs require a higher-level data product than what OOI provides through its standard data dissemination, and hence a quality controlled, salinity-calibrated data product has been produced. Data are in text format, data description is in PDF.

The 2013 PIRATA Northeast Extension (PNE) and Aerosols and Ocean Science Expedition (AEROSE) Cruise RB-13-01 was designed to: (1) collect a suite of oceanographic and meteorological observations in the northeast Tropical Atlantic; (2) recover and redeploy the four moorings that belong to the Northeast Extension of the PIRATA array; (3) recover and redeploy the TFlex mooring near 20N, 38W; (4) to perform a sensor swap for the PIRATA mooring at 0ºN, 23ºW; and (5) to recover and redeploy two hydrophone moorings as well as deploy an additional hydrophone mooring. The oceanographic component of (1) includes the collection of data along 23ºW using CTD-O2/rosette/LADCP, XBTs and an underway CTD and the collection of XBT and underway CTD profiles on the return transit to Puerto Rico. The 23W section cuts through the climatologically significant Tropical North Atlantic (TNA) region, including the southeast corner of the subtropical North Atlantic (a region of subduction for the subtropical cell circulation); the Guinea Dome and oxygen minimum shadow zone where the subtropical and tropical gyres meet, and the Tropical Atlantic current system. The meteorological component of (1) focused on the measurement of aerosols, ozone and atmospheric conditions. All scientific goals of RB-13-01 were achieved.

This dataset contains water temperature, salinity, and other parameters collected by CTD from research vessel Oceanus in the north Pacific Ocean off California. Cruise OC1511A by research vessel Oceanus in November 2015 had the objective to service moorings for the CCE (California Current Ecosystem) project. To calibrate and validate the mooring data, CTD casts with water samples were done. The CTD data are reported here. The CTD data have been quality-controlled and adjusted using the water sample data. Data quality is acceptable, but affected by bad weather which led to unsteady motion of the instrument package through the water. The raw CTD data files are available through the Rolling Deck to Repository program (R2R, see references), and the water sample data will be published through the Ocean Carbon and Acidification Data Portal at NCEI. Data are in NetCDF.

This dataset contains near surface water temperature, salinity, and pressure taken by CTD from drifting floats in the North Pacific Ocean. The main target of our study is further understanding of ENSO and associated processes. In addition to existing observing system, which includes the Global Tropical Moored Buoy Array, ARGO floats, ship observation and so on, this surface drifting mission will be one of the key components of this objective. The purpose of the surface drifting buoy mission is to obtain the atmospheric and oceanic variables, which are associated with heat exchange between the ocean and atmosphere, along the western Pacific warm pool. This mission was conducted as a part of “the Global Drifter program,” which is an international program designed to improve climate prediction. This is US State Department MSR RATS U2018-007, USFWS SUP 12541-18006. Data submitted as part of the World Data Service for Oceanography. Data are in text format.

The November - December 2013 PIRATA (Prediction and Research Moored Array in the Tropical Atlantic) Northeast Extension (PNE) and Aerosols and Ocean Science Expedition (AEROSE) cruise RB-13-06 was designed to (1) Collect oceanographic and meteorological observations in the northeastern tropical Atlantic, (2) Recover and redeploy the PIRATA Northeast Extensions’ four Autonomous Temperature Line Acquisition (ATLAS) moorings, and (3) Recover and redeploy the TFlex mooring located near the 20°N, 38°W ATLAS mooring. The oceanographic component of (1) includes measurements of conductivity, temperature, pressure, oxygen concentration, and horizontal velocity from CTD casts and measurements of temperature and depth from XBT deployments. The majority of the measurements were acquired along the 23°W meridian, which samples the southeastern corner of the subtropical North Atlantic, a region of subduction that is important for the subtropical cell circulation; the Guinea Dome and oxygen minimum zone, where the subtropical and tropical gyres meet; and the tropical current system and equatorial waveguide. The meteorological component of (1) focused on measurements of atmospheric aerosols, temperature, water vapor, ozone, trace gases, winds, and other properties. All scientific goals of RB-13-06 were achieved.
