Limnological studies of Dry Valley lakes: water parameters (pH, conductivity, nutrients, temperature), uranium content, trace elements, isotopic ratio and tritium concentrations, and geochemical samples
Abstract:
A large number of saline and freshwater lakes and ponds of the Dry Valley area and crater lakes behind the McMurdo station were visited for limnological study including Lake Fryxell of the Taylor Valley, Lake Vanda, Don Juan Pond and unnamed ponds in the Labyrinth of the Wright Valley in the Dry Valleys. Water samples were collected for all the visited lakes and ponds. Measurement of the samples ... include water temperature, pH, conductivity, inorganic nitrogen compounds, vertical distribution of nutrient matters, major and minor chemical elements and radionuclides and the size of the pond were made. Geochemical samples, such as evoporites and bottom sediments of saline ponds were collected to study the evolutional history of the saline waters in this area. To study the background level of radionulcides in the Dry Valleys, water, soil, moss and algal samples were collected. Samples were also analysed for neutron activation analysis of trace elements, measurements of the uranium content and its isotopic ratio to determine the origin of salts and the evolutionary history of the saline waters and tritium concentrations. Inorganic constituents in the lakes and ponds and their surroundings (algal, moss, lichen and soil) were studied from samples and the vertical distribution of bacteria.

East Bay bottom sampling began in January 1993. Both have been continuously in service since then. Data from the two oyster bar stations, Cat Point and Dry Bar, has been collected since 1992, although this is the first year that the data from these stations will be submitted to the CDMO. During the year 2002, all deployments utilized YSI dataloggers. One YSI 6000-model sonde was used for two deployment periods early in the year. After February 2003, YSI 6600 models and 6600 EDS models were used.

Data are missing due to equipment failure where no probe is deployed, maintenance/calibration of equipment, elimination of obvious outliers, or elimination of data due to calibration (both pre and post) problems. For more details on deleted data, see the Anomalous Data Section (11.). To find out more details about missing data, contact the Research Coordinator at the site submitting the data. LINEAGE/PROCESS STEP: PROCESS DESCRIPTION: Additional Description: Entry verification YSI data are downloaded directly from the YSI 6600 into the EcoWatch (version 2.16) software, plotted, and initially analyzed for major anomalies and missing data. YSI raw data files are then downloaded as a comma delimited file (.cdf) and imported into Microsoft Excel as a comma-space delimited file (.csv). These raw data files are then organized into standardized monthly data sets using the CDMO import.xls macros. The import.xls macros generate a monthly spreadsheet, import the raw data, fill all empty cells with periods, change feet to meters for depth readings if necessary, and save the monthly files as either a .csv or .xls file. Once in monthly format, these files are then run through the cdmomac3.xls macros which identify outliers, insure correct number of data points for each Date/Hour count, and format the columns in the correct order and size. The monthly files are then carefully edited by staff for data anomalies which are identified in Section 11 (Data Anomalies) of this document. Any data that are deleted by staff are replaced with periods and identified in Section 11. Monthly edited files are then FTP'd to CDMO in text format, along with an updated metadata form. Kim Miller is responsible for all the QA/QC process. PROCESS DATE: 20060208

ACCESS CONSTRAINTS: Data collected in conjunction with the National Estuarine Research Reserve System's (NERRS) System-wide Monitoring Program (SWMP) is considered public information. Please see site for further information: http://cdmo.baruch.sc.edu/aboutdata.htm LIABILITY: Distribution The Centralized Data ... Management Office re-processed all SWMP water data collected from 1995-2002 to include an identifying station code (three letter reserve code, two letter sampling site code and data type code), a four digit year date stamp (mm/dd/yyyy) and a corrected time column (hh:mm). With the new format, the use of periods to denote deleted or missing data has been abandoned. Hence, all periods contained in the SWMP water data collected prior 2003 were removed and left blank.
