Following the May 2005 acid crater lake flood at Chiginagak volcano, DGGS has been monitoring crater lake water that flows into Indecision Creek, Mother Goose Lake, and the King Salmon River.This data table provides information on water samples collected between 2005 and 2011 near Chiginagak volcano, including:sample ID, latitude, longitude, location description, pH, and cation and anion chemistry results.
The purpose of this data table is to document the sample ID, latitude, longitude, location description, pH, and cation and anion chemistry results of water samples near Chiginagak volcano as referred to in this report:Schaefer, J.R., Scott, W.E., Evans, W.C., Wang, Bronwen, McGimsey, R.G., 2011, Summit crater lake observations, and the location, chemistry, and pH of water samples near Mount Chiginagak volcano, Alaska: 2004-2011:Alaska Division of Geological & Geophysical Surveys Report of Investigations RI 2011-6.
This distribution package provides the user with CSV and a Microsoft Excel versions of the file. The metadata describes the CSV file. If creating a shapefile with this data be aware that the attribute field names will be truncated after ten characters. The DGGS metadata standard extends the FGDC standard to also include several elements that are required to facilitate our internal data management. These elements relate individual data items to a common dataset. This dataset describes a single layer titled:

Attribute values listed in the final table were checked for consistency by cross-referencing field data sheets and laboratory chemical results as well as plotting the locations and attributes in a GIS.
Positional accuracy was checked by plotting locations in a GIS and comparing placed points with topography and map attributes. Chemical values and pH were also plotted in GIS and compared in time series to ensure logical accuracy.
At the time of writing, some pH values and chemical data were not processed for samples collected in 2011. When these data become available, they will be provided as an addendum to this table.Conductivity, pH, temperature, and chemical samples were not collected at all sites.At some sites, only pH paper was available, thus a range of pH is given versus sites where pH was taken with a digital pH meter. In the latter case, pH is given to the nearest 1/10th.
Horizontal positions (latitude and longitude) were determined with handheld GPS receivers.Although in most cases latitude and longitude are given in decimal degrees to 5 decimal places, the accuracy of this position is likely more coarse, as a GPS station may have been taken 20 meters or more from the exact site in the stream where the water sample was actually taken. Users reoccupying the sampling sites should use care to read the location description information to determine what stream corresponds to what sample site, especially near confluences.

inductively coupled plasma mass spectrometry (ICP-MS) procedures
Latitude and Longitude information was collected using various hand-held GPS units. Location information was recorded in a field notebook, then transferred later to the project database. The pH values were measured in the field using various digital pH meters. The pH meter was calibrated at least once per day using a 2- to 3-point calibration with pH standards of 4, 7, and 10. Surface water samples taken for cation and anion analysis were filtered in the field using a 0.45 micron filter and peristaltic pump, following standard clean techniques.Anion concentrations were determined at the U.S. Geological Survey (USGS) laboratories in Menlo Park, California using a DIONEX ICS-2000 ion chromatograph with hydroxide eluent.Alkalinity (as bicarbonate) was analyzed by potentiometric titration on samples with pH > 5.Samples that contain more than about 100 mg/L of any one analyte are diluted prior to analysis, resulting in more than one detection limit per analyte.In some cases "bdl" is used as the default "below detection limit" indicator. If concentrations of analytes were high (generally >100 mg/L) Major cation and trace element concentrations were determined at the USGS Mineral Program laboratories in Denver, Colorado, by inductively coupled plasma mass spectrometry (ICP-MS) using procedures described by Lamothe et al.,(2002).
