Miscellaneous Release—Data 356
Geological, Geochemical and Geophysical Data Related to the Centennial Lake Area, Grenville Province; by M. Duguet. This digital data release contains field photographs, and whole-rock geochemistry and magnetic susceptibility data collected as part of the Centennial Lake area 1:20 000 scale bedrock geology mapping project during the summer of 2015. Also included is a previously published article related to the project. This release comprises 202 images (as .jpg files), 2 Microsoft® Excel® 2013 (.xlsx) workbook files and 3 documents in portable document format (.pdf).

Surficial Mapping and Sampling

Miscellaneous Release—Data 364
Lake Sediment and Water Geochemical Data from the Nakina–Marshall Lake Area, Northwestern Ontario; by L.A. Handley and R.D. Dyer. This digital data release provides deep and shallow lake sediment geochemical data and lake water geochemical data, including quality control data, for samples collected from a total of 1638 sites. The survey was conducted during the summers of 2014 and 2015 in the area between Nakina and Marshall Lake in northwestern Ontario. Deep and shallow lake sediment were analyzed for loss on ignition (LOI); and by instrumental neutron activation analysis (INAA, for deep sediment only), inductively coupled plasma atomic emission spectroscopy (ICP–AES) and inductively coupled plasma mass spectrometry (ICP–MS). Lake water samples were analyzed by inductively coupled plasma atomic emission spectroscopy (ICP–AES), inductively coupled plasma mass spectrometry (ICP–MS) and ion chromatography (IC). Quality control data consisting of the results from the analysis of duplicate pairs and certified reference materials are included in this release. The ICP–MS, ICP–OES, IC and LOI analyses were completed by Geoscience Laboratories and INAA analysis by Becquerel Laboratories. All location information is presented as Universal Transverse Mercator (UTM) co-ordinates using North American Datum 1983 (NAD83) in Zone 16. The data are available as 21 Microsoft® Excel® 2013 (.xlsx) format files. Available on 1 CD. $20.00.

Groundwater Studies

Open File Report 6347
High Resolution Seismic Reflection Profiles for Groundwater Studies in Simcoe County, Southern Ontario; by A.J.-M. Pugin, B. Dietiker, R.P.M. Mulligan, H.L. Crow, K. Brewer, T. Cartwright, D.R.B. Rainsford, A.F. Bajc, D.R. Sharpe, and H.A.J. Russell. Also released as Geological Survey of Canada, Open File 8383, 23p. $9.00.
