Correction to: Aquatic Sciences (2018) 80:1  https://doi.org/10.1007/s00027-017-0553-0

In the original publication, the incorrect GIS map projection was used to calculate lake surface areas and catchment areas that were presented in Table 1. These errors do not impact the results or interpretation in any way (they provided general context for our study area). The values of ‘Surface area, Catchment area and the Catchment to surface area ratio’ are corrected in the table as shown below.

Table 1

Physical characteristics and summary Hg accumulation results of the three study lakes (BRW100, ATQ206, RDC312) on the Arctic Coastal Plain of Alaska; Hg accumulation trends were assessed using Mann–Kendall tests (a p value < 0.05 denotes a significant temporal trend and the Kendall’s tau denotes the direction and magnitude of the relationship; McLeod 2015); catchments were delineated, and percent growth was calculated using ArcMap™10.2.2 (ESRI 2016)
