Coastal thermograph network
공공데이터포털
This dataset contains the surface temperature and salinity data of the enlarged coastal thermograph network of the St. Lawrence river, estuary and gulf system. It includes data from the Canadian Hydrographic Service water level network (SINECO), the Department of Fisheries and Oceans (DFO)-Quebec long-termed thermograph monitoring program network and the oceanographic buoy network. Each station is linked with a .png file showing the temperature and salinity time series and with a .csv file containing the surface temperature and salinity data themselves (columns : Station,Latitude,Longitude,Date(UTC),Depth/Profondeur(m),Temperature/Température(ºC),Salinity/Salinité(psu)). Supplemental Information A detailed description of the networks (SINECO, oceanographic buoys and the DFO-Quebec thermograph monitoring program) is available at the St. Lawrence Global Observatory (SLGO) portal : SINECO : https://ogsl.ca/en/tide-gauges-dfo-chs/ Oceanographic buoys : https://ogsl.ca/en/marine-conditions-buoys-dfo/ Thermographs: https://ogsl.ca/en/marine-conditions-thermographs-dfo/ Technical Reports related to the Thermograph Network (the last one is also available at the same hypertext link mentionned above) : Pettigrew, B., Gilbert, D. and Desmarais R. 2016.

Surface and oceanographic profile temperature, salinity, and other measurements using CTD, thermosalinograph, ADCP, and Scanfish, taken from R/V Coriolis II in the San Jorge Gulf and environs 2014-02-04 to 2014-02-10 (NCEI Accession 0170034)

This dataset contains surface and subsurface measurements of temperature, salinity, oxygen, current velocity, and other ocean environmental variables from the cruise Coriolis II in San Jorge Gulf (Argentina) in February 2014 using winched CTD, towed CTD, thermosalinograph, and ADCP, for the purpose of studying the frontal dynamics associated with a region of high tidal dissipation rates. The data are in text files (csv and cnv). The data are part of the PROMESse (Multidisciplinary program for the study of the ecosystem and marine geology of San Jorge Gulf and the coast of the Province of Chubut) international cooperation research program among the Ministry of Science and Technology (MINCyT), the National Scientific and Technical Research Council (CONICET), the Province of Chubut (Argentina) and the University of Quebec at Rimouski (UQAR/ISMER, Canada). Within the framework of this program, these data were collected during the second leg of Coriolis II cruise as a part of the MARES (Marine Ecosystem Health of the San Jorge Gulf: Present status and Resilience capacity) project.
Bottom water temperature and salinity in the Estuary and Gulf of St.Lawrence
공공데이터포털
Gridded temperature and salinity of the Estuary and Gulf of St. Lawrence bottom waters including shallow waters. Data are a result of a 3D interpolation on a 1km x 1km x bottom depth grid. They mostly come from the 2 multidisciplinary surveys but all the available CTD data sampled in August and September were used. The dataset contains 24 layers: one layer per year per variable from 2014 to 2023, two layers of temperature and salinity climatologies and two layers of anomalies for the last year. Purpose Since 1990, the Department of Fisheries and Oceans has been conducting an annual multidisciplinary survey in the Estuary and northern Gulf of St. Lawrence using a standardized protocol. In the southern Gulf of St. Lawrence, these bottom trawl surveys has been carrying out each September since 1971. These missions are an important source of information about the status of the marine ressources. The objectives of the surveys are multiple: to estimate the abundance and biomass of groundfish and invertebrates, to identify the spatial distribution and biological characteristics of these species, to monitor the biodiversity of the Estuary and Gulf and finally, to describe the environmental conditions observed in the area at the moment of the sampling. The southern Gulf surveys are realized using the following standardized protocol: Hurlbut,T. and D.Clay (eds) 1990.

Temperature, salinity and other variables collected from discrete sample and profile observations using CTD, bottle and other instruments from DISCOVERY in the South Atlantic Ocean from 1992-12-22 to 1993-02-01 (NCEI Accession 0144287)

This dataset includes discrete sample and profile data collected from DISCOVERY in the South Atlantic Ocean from 1992-12-22 to 1993-02-01. These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), DISSOLVED OXYGEN, Delta Oxygen-18, HYDROSTATIC PRESSURE, NITRATE, SALINITY, WATER TEMPERATURE, nitrate + nitrite content (concentration), phosphate and silicate. The instruments used to collect these data include CTD and bottle. These data were collected by Brian A. King and David Hydes of National Oceanography Centre, Southampton (NOCS) and Peter M. Saunders of University of Southampton; Department of Oceanography as part of the WOCE_A11_74DI19921222 dataset. CDIAC associated the following cruise ID(s) with this dataset: WOCE_A11_1992 The World Ocean Circulation Experiment (WOCE) was a major component of the World Climate Research Program with the overall goal of better understanding the ocean's role in climate and climatic changes resulting from both natural and anthropogenic causes. The CO2 survey took advantage of the sampling opportunities provided by the WOCE Hydrographic Program (WHP) cruises during this period between 1990 and 1998. The final collection covers approximately 23,000 stations from 94 WOCE cruises.
