This dataset includes mercury and other constituent concentration and physical properties data for seven deep sediment profiles (ranging from 79 cm to 214 cm in length) collected from the thalwag of Alviso Slough, a major tributary to South San Francisco Bay (California, USA). Field sampling occurred during May 2012 (4 sites) and January 2016 (3 sites). Each profile was comprised of 1–4 core sub-sections, which were collected from adjacent boreholes with 10–18 cm of vertical overlap. This data product includes two data tables (*.csv): 1) ‘T1_ALSL_DC_Sed_Data.csv’, the deep core analytical results; 2) ‘T2_ALSL_DC_QA_Data.csv’, quality assurance data. The two image files, ‘ALSL_DC_Log_2012.pdf’ and ‘ALSL-DC_Log_2016.pdf’,...

Boreal ecosystems comprise about one tenth of the world’s land surface and contain over 20 % of the global soil carbon (C) stocks. Boreal soils are unique in that the mineral soil is covered by what can be quite thick layers of organic soil. These organic soil layers, or horizons, can differ in their state of decomposition, source vegetation, and disturbance history. These differences result in varying soil properties (bulk density, C content, and nitrogen (N) content) among soil horizons. These data were used in a manuscript (https://doi.org/10.5194/essd-2019-114) where these soil properties, as represented by over 3000 samples from Interior Alaska, were summarized. We also examined how soil drainage and stand...
