Routed regional river centerline data layer using the polylineM feature format with measures in kilometers. The stream route layer includes stream locations where, on the basis of the raster model used to create the data layer, surface water may have once existed, but is now piped, culverted or thought to be buried. Likewise the layer includes centerlines through water bodies, i.e. portions of streams that connect with larger bodies of water such as wetlands, ponds, etc. Thus many portions of a stream route feature are included primarily to complete the centerline network for routing purposes.

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’,...
