Water temperature and water level are significant environmental factors affecting ecology of anadromous fish. Large-scale freshwater monitoring networks remain sparse, yet environmental protocols rely heavily on water temperature and water levels to assist decision making on river closures. Our river monitoring project in Newfoundland and Labrador provides river water temperature and river water level for salmon rivers across the province. 72 temperature loggers are deployed across 24 river systems in Newfoundland and Labrador. Temperature loggers are deployed in approximately 30 cm of water and remain in river year-round. Loggers consist of Onset level loggers, tidbit loggers, and pendants or Innovasea minilogs. Some loggers are deployed in duplicate at locations to provide data redundancy in event of equipment loss or failure. Equipment is monitored throughout the season to ensure proper placement in water columns, with downloads taking place during monitoring trips.

This dataset includes surface underway measurements of partial pressure of carbon dioxide (pCO2), water temperature, salinity, barometric pressure and other variables during R/V Endeavor Atlantic Zone Monitoring Program (AZMP) cruises in Gulf of Maine, Scotian Shelf, Newfoundland Shelf and North Atlantic Ocean from 2017-11-24 to 2017-12-16.

1999 to 2023 surface temperature and salinity measured along the track of commercial ships, mostly between Montreal (Quebec) and St. John's (Newfoundland). Monitoring of surface water conditions in the Estuary and Gulf of St. Lawrence is carried out with different complementary methods such as thermosalinographs (TSG) installed on commercial ships. These ships are sailing all year long from Montreal to St. John’s, one round trip per week, and are sampling water near the surface (3 to 8 meters deep) to determine the temperature and salinity all along the route. Purpose The recorded data are used as input to numerical forecasting models for sea ice conditions and as a monitoring tool for the Gulf of St. Lawrence. Annual reports are available at the Canadian Science Advisory Secretariat (CSAS), (http://www.dfo-mpo.gc.ca/csas-sccs/index-eng.htm).

The water level data comes from the groundwater monitoring network of Nova Scotia (Canadian province). Each well in the observation network is equipped with a hydrostatic pressure transducer and a temperature sensor connected to a data logger. A second pressure transducer located above the water surface allows for adjusting the water level according to atmospheric pressure variations. The time series refers to the level below which the soil is saturated with water at the site and at the time indicated. The water level is expressed in meters above sea level (MASL). The dataset consists of a general description of the observation site including; the identifier, the name, the location, the elevation and a series of numerical values designating the water levels at a defined date and time of measurement.

This dataset includes surface underway measurements of partial pressure of carbon dioxide (pCO2), water temperature, salinity, barometric pressure and other variables during the CCGS Hudson Atlantic Zone Offshore Monitoring Program (AZOMP) cruises in Labrador Sea, Scotian Shelf, Newfoundland Shelf and North Atlantic Ocean from 2016-04-28 to 2016-05-23.

Temperature profile data were collected using CTD casts in the North Atlantic Ocean from July 21, 1982 to July 28, 1982. Data were collected and submitted by Dr. Yuri Popov of the Ukrainian Scientific Centre of the Ecology of Sea (UkrSCES).

The data are from the Newfoundland Energetic Activity Polygon (NEAZO). Approximately 20 years ago a leading Russian Scientist, Akademician Marchuk (Mathematician) proposed a theory that there are some areas in the ocean where the atmospheric interaction is very strong. Hence we have to monitor these areas (key areas, aka Centers of Actions). This area he called Energo Active Zone, zone active energetically. A lot of energy is coming from the ocean to atmosphere and the reverse. There are several active zones, one being Newfoundland. A polygon was established in the Newfoundland area. The Russian use the acronym NEAZO; the Americans use the acronym NEP.

The SURATLANT dataset (SURveillance ATLANTique) consists of individual data of temperature, salinity, dissolved inorganic carbon (DIC) and its isotopic composition d13CDIC, total alkalinity (At), inorganic nutrients and water stable isotopes (δ18O and δD) collected mostly from ships of opportunity since 1993 along transects between Iceland and Newfoundland (shipping company EIMSKIP), as well as, since 2014, between west Greenland and Danemark (shipping company RAL). The data have been validated, qualified, and their accuracy and the overall characteristics of the data set are presented in a paper (Reverdin et al., 2018). The csv file provides a listing of the data with one line for each collection date. This includes collection date, position, temperature, salinity, and the measured, validated and in some cases adjusted variables, as well as a quality code following WOCE/GLODAP format. For water isotopes and isotopic composition of inroganic carbon, a code is also provided indicating the method of measurement used. An additional text-file provides a normalized average seasonal cycle of the 10 variables measured in 5 boxes between the vicinity of Newfoundland to the south-west of Iceland (corresponding to the figure 3 of the paper Reverdin et al in the References). Format and information is provided in the top 25 lines and the gridded seasonal cyle data start at line 26.

The Department of Fisheries and Oceans Canada (DFO), Newfoundland and Labrador Region, has undertaken stratified-random multi-species surveys in portions of Northwest Atlantic Fisheries Organization (NAFO) subareas 2 and 3 since the early 1970’s. The current survey design covers an expansive spatial area, spanning six NAFO divisions (2HJ3KLNO) and 515,000 km2 in the autumn and four NAFO divisions (3LNOP) and 324,000 km2 in the spring. The survey aims at determining the distribution and abundance of commercial and non-commercial fish and invertebrate species with respect to position, depth, and temperature, and to collect biological samples.

  In 1989 DFO developed a shock-absorbing CTD sled containing a Seabird model SBE-19 CTD that could be mounted on a trawl, which is now the primary instrument used to collect physical oceanographic data (e.g., T, S) during multi-species surveys in NL region. The package attached to the trawl head-ropes records time, water pressure, temperature, and conductivity for the duration of the fishing set. In the event of instrument failure an expendable bathythermograph (XBT) is deployed.

  In addition, this survey samples the high-frequency station, Station 27, in collaboration with the Atlantic Zone Monitoring Program (AZMP).

  This record includes only hydrographic/CTD data collected during the spring and autumn multi-species surveys, conducted between 1995 to present.
