Title of datasetFortune Bay (NL, Canada) oceanographic observations May 2015 - May 2017
Narrative summary of datasetA comprehensive set of oceanographic data were collected in Fortune Bay, a broad, mid-latitude fjord located on the south coast of Newfoundland (Canada). The dataset was gathered in partnership with IFREMER who collected data around the adjacent French archipelago of Saint-Pierre and Miquelon. The dataset consists of data from taut-line moorings, land-based stations (a tide gauge and a couple of weather stations) and CTD profiles performed during mooring maintenances (~every 6 months). Parameters covered by the moorings include water column temperature (thermistor chain), salinity (2 points/depths per mooring), dissolved oxygen (on a limited number of moorings, within the surface layer) as well as current profiles (ADCP). Land-based stations monitored water level and temperature (tide gauge) and wind speed and direction, atmospheric pressure, air temperature and solar radiation (weather station). CTD profiles include dissolved oxygen for the most part. The program lasted two full years from May 2015 to May 2017 and sampling interval varied from 1-60 min depending on the instrument. Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.
Summary of processing methodologyTo provide some added value, the ADCP backscatter datawere processed to convert the raw returned signal strengthindicator (RSSI,Ein equation below), a measure of acousticpressure received by the transducers, to a corrected backscat-ter volume Sv, proportional to the amount (i.e. volume) ofparticles present in the water column. The method used to dothe correction is an updated version of the popular Deinesmethod (Deines, 1999) published by Mullison (2017). Transducer temperature measured at trans-ducer head and the salinity value selected during instrumentsetup (ES command; 32 in our deployments) were used tocalculate the water absorption (a) along the range (fromtransducer)R, thereby implying homogeneous water condi-tions. The transmit pulse lengthLDBMwas calculated usingbin size (1–3 m) and beam angle (20?) values. Default valuesof constantCand transmit powerPDBWprovided by Mulli-son (2017) were used
