Description
Summary:This dataset contains navigational, bathymetric, meteorological and sea surface hydrography data from fixed sensor arrays on the RRS James Clark Ross (JCR) cruise JR17005, undertaken between May and June 2018 in the Fram Strait. The oceanlogger system recorded sea surface properties and most meteorological measurements. Measurements of wind, depth and position were stored in separate (anemometer, EA600 and Seatex GPS) streams. The oceanlogger data steam recorded measurements at an average frequency of 0.2 Hz; all other data streams recorded at an average frequency of 1 Hz. Small variations in recording frequency were accounted for during data processing. Each data set was processed by filtering noise and erroneous measurements, and then applying per minute medians to generate smoothed data and smaller file sizes. Measurements taken in days before the first sampling event (13/05/2018) were omitted from the analyses. Underway salinity was calibrated using samples taken from the underway system and further salinity samples taken from niskin bottles fired within the top 10 m of the water column. All samples were analysed on a Guildline Autosal. The authors do not have any concerns over the quality of the data set and values are consistent with similar data reported in the wider literature. The data were collected as part of the National Environment Research Council (NERC) Changing Arctic Ocean (CAO) project, ARISE. The British Oceanographic Data Centre (BODC) created the metadata entry and is responsible for holding master copies of the data.
