Details of Bottom Water Temperature collected in Real-Time from Commercial Fishing Gear in Gulf of Maine and Southern New England Shelf


Dataset identification

Title of datasetBottom Water Temperature collected in Real-Time from Commercial Fishing Gear in Gulf of Maine and Southern New England Shelf
Narrative summary of datasetDataset contains bottom temperature data from both fixed and mobile gear types (e.g. traps, trawlers, scallopers, long-liners) in the Gulf of Maine and the South New England Bight. The time series begins in 2015 and runs in real-time until today. The water depths range from 1- 900 meters. The variability associated with tidal, wind, seasonal, and inter-annual processes can be depicted at nearly all sites in this multi-year time series. This data was collected as part of the Environmental Monitors on Lobster Traps (eMOLT) project - a non-profit collaboration of industry, science and academics devoted to the monitoring of the physical environment of the Gulf of Maine and the Southern New England Shelf. 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 methodology1) The fishermen attach the sensor to the lobster trap for the entire duration of the fishing season. 2) The science party mails a self-addressed-stamped envelope to the fishermen near the end of the year asking for: a) probes to be returned, b) documentation on any changes in mooring location/depth, c) catch for traps with probes attached (optional) 3) The data is downloaded, cleaned, filtered (for occasional spikes associated with hauling), plotted, archived, and posted on the web 4) Probes are immersed in a controlled ice-bath to check on biases and calibrations 5) The science party reinitialises the temperature sensor at hourly sample rate and mails it back to participants along with hard copy plots ofthe data.
