Our sampling site was located in Nova Scotia, Canada (a), and specifically within the Bedford Basin [inset of a; sampling site (star) is also known as HL0 = 44.6936 latitude, −63.6403 longitude]. (b) Schematic representation of variables and conditions measured during this study, included: sampling depths for DNA, chlorophyll-a and concentrations for dissolved nutrients (nuts; which included PO4−, NO3−, NO2−, NH4+ and Si) along with CTD profiles. Weekly measurements from 2014 to 2017 included: temperature profiles (c), nitrate concentrations in the euphotic (1, 5 and 10 m; cyan circles) and in the aphotic zone (60 m; orange circles; d), and chlorophyll-a concentrations in the euphotic zone (the green line is the average for the three depths 1, 5 and 10 m; e). Grey arrows denote colder and warmer winters for 2015 and 2016, respectively, as detailed by Haas et al.32. Image credit for yellow buoy; Robert Brazzell.
