| contents | Tab named "Incrmnt. measurements, chron." contains annual growth increment measurements in micrometers of fourteen Arctica islandica shells collected from the Fladen Ground in the North Sea at coordinates 58.994° N, 0.291° E. Specimens 0401246, 0401254, 0401258, 0401260, 0401262 were originally described in Butler et al. (2009). Additionally, "Incrmnt. measurements, chron." contains the detrended and normalised increment measurements and a growth increment chronology. These were calculated with the standard dendrochronology software ARTSAN using a negative exponential function. The growth increment chronology also includes the average shell-pair correlation in a 30-year sliding window (r̄) and the expressed population signal for the same sliding window (EPS). Tab named "δ13C, oSE, δ13CṠ" contains stable carbon isotope values derived from eight A. islandica shells shown in tab "Incrmnt. measurements, chron." and two other shells collected from the same location. The measurements also include the internal precision (sigma) and the relative weight of each sample (inverse of sigma squared). Additionally, "δ13C, oSE, δ13CṠ" includes a calculation of the oceanic Suess effect based on a 2-term weighted Fourier regression of δ13C. δ13CṠ is defined as δ13C - oSE. The last two columns are the weighted average of δ13CṠ and the weighted sigma average. Tab named "MD and HR measurements" contains the counts of maximum diatom assemblage in the standard area B2 of the Sir Alister Hardy Foundation for Ocean Science Continuous Plankton Recorder and the herring recruitment count for the North Sea, English Channel, Skagerrak and Kattegat. The counts are shown in linear and logarithmic scales and were obtained from ICES (2018) and Johns (2016). Tab named "Eq. 7 results" contains the reconstructed herring recruitment for the North Sea using an equation developed in this study from 1551 to 2005. Tab named "CPUE" contains the catch per unit effort (C/E) of Dutch, English (Lowestoft) and Scottish (Perterhead, Southeast Scotland) herring fisheries. The catch is given in kilograms or 10^3 kilograms and the effort is defined as either the number of boats or the total area of driftnet. The data comes from Coull (1986), Cushing (1968), Jones et al. (2016) and Poulsen (2008). |
