Jill S. Baron 20241206 spreadsheet Loch Vale watershed participates in the National Atmospheric Deposition Program/ National Trends Network (https://nadp.slh.wisc.edu/networks/national-trends-network/) as NADP site CO98. Much of the activity reported in field notebooks revolves around collecting weekly samples of precipitation (rain or snow). Samples from NADP sites are collected according to common procedures; samples are sent to the NADP Analytical Facility in Madison Wisconsin for chemical analysis. Samplers include an Aerochem Metrics wet deposition collector and one to two rain gages. The gages were Belfort rain gages from 1983-2010. They were co-located with a NOAH IV gage from 2007-2010 when the Belfort gage was dismantled and the NOAH IV gage became the primary precipitation collection device. The gages were can be downloaded from the NADP link listed in the 'Larger Work' section. Field notebooks record activities related to the collection of water quality samples from The Loch, Sky Pond, Andrews Tarn, Glass Lake, Emerald Lake, Lake Haiyaha, Louise Lake and Lake Husted in Rocky Mountain National Park. The data from the samples collected in Loch Vale watershed can be found at the USGS National Water Information System links identified in the 'Larger Work' section. https://doi.org/10.5066/P1CXWAVP Jill S. Baron 20231001 tabular digital data The National Atmospheric Deposition Program (NADP) monitors precipitation chemistry of the United States. The program is a cooperative effort between many different groups, including federal, state, tribal and local governmental agencies, educational institutions, private companies, and non-governmental agencies. The program office of NADP is at the Wisconsin State Laboratory of Hygiene at the University of Wisconsin-Madison. The NADP site, CO98, in Loch Vale watershed, is one of more than 200 similar wet precipitation monitoring sites in North America that collect weekly samples according to fixed nation-wide protocols. https://nadp.slh.wisc.edu/sites/ntn-CO98/ https://maps.waterdata.usgs.gov/mapper/nwisquery.html?URL=https://waterdata.usgs.gov/usa/nwis/inventory?search_station_nm=The%20Loch&search_station_nm_match_type=beginning&format=sitefile_output&sitefile_output_format=xml&column_name=agency_cd&column_name=site_no&column_name=station_nm&list_of_search_criteria=search_station_nm&column_name=site_tp_cd&column_name=dec_lat_va&column_name=dec_long_va&column_name=agency_use_cd https://maps.waterdata.usgs.gov/mapper/nwisquery.html?URL=https://waterdata.usgs.gov/usa/nwis/inventory?search_station_nm=Sky%20Pond&search_station_nm_match_type=beginning&format=sitefile_output&sitefile_output_format=xml&column_name=agency_cd&column_name=site_no&column_name=station_nm&list_of_search_criteria=search_station_nm&column_name=site_tp_cd&column_name=dec_lat_va&column_name=dec_long_va&column_name=agency_use_cd https://maps.waterdata.usgs.gov/mapper/nwisquery.html?URL=https://waterdata.usgs.gov/usa/nwis/inventory?search_station_nm=Glass%20Lake&search_station_nm_match_type=beginning&format=sitefile_output&sitefile_output_format=xml&column_name=agency_cd&column_name=site_no&column_name=station_nm&list_of_search_criteria=search_station_nm&column_name=site_tp_cd&column_name=dec_lat_va&column_name=dec_long_va&column_name=agency_use_cd https://maps.waterdata.usgs.gov/mapper/nwisquery.html?URL=https://waterdata.usgs.gov/usa/nwis/inventory?search_station_nm=Andrews%20Tarn&search_station_nm_match_type=beginning&format=sitefile_output&sitefile_output_format=xml&column_name=agency_cd&column_name=site_no&column_name=station_nm&list_of_search_criteria=search_station_nm&column_name=site_tp_cd&column_name=dec_lat_va&column_name=dec_long_va&column_name=agency_use_cd https://maps.waterdata.usgs.gov/mapper/nwisquery.html?URL=https://waterdata.usgs.gov/usa/nwis/inventory?search_station_nm=Lake%20Haiyaha&search_station_nm_match_type=beginning&format=sitefile_output&sitefile_output_format=xml&column_name=agency_cd&column_name=site_no&column_name=station_nm&list_of_search_criteria=search_station_nm&column_name=site_tp_cd&column_name=dec_lat_va&column_name=dec_long_va&column_name=agency_use_cd https://waterdata.usgs.gov/nwis/inventory?agency_code=USGS&site_no=401843105400601 https://maps.waterdata.usgs.gov/mapper/nwisquery.html?URL=https://waterdata.usgs.gov/usa/nwis/inventory?search_station_nm=Lake%20Husted&search_station_nm_match_type=beginning&format=sitefile_output&sitefile_output_format=xml&column_name=agency_cd&column_name=site_no&column_name=station_nm&list_of_search_criteria=search_station_nm&column_name=site_tp_cd&column_name=dec_lat_va&column_name=dec_long_va&column_name=agency_use_cd https://waterdata.usgs.gov/nwis/inventory?search_station_nm=Husted&search_station_nm_match_type=beginning&format=station_list&group_key=county_cd&list_of_search_criteria=search_station_nm https://waterdata.usgs.gov/nwis/inventory?search_station_nm=Louise&search_station_nm_match_type=beginning&format=station_list&group_key=county_cd&list_of_search_criteria=search_station_nm https://waterdata.usgs.gov/nwis These files consist of scanned field notebooks from long-term research and monitoring conducted in the Loch Vale watershed, Rocky Mountain National Park from June 17, 1981, through September 19, 2023. There are 72 individual PDF files. They are accompanied by a spreadsheet that serves as a pointer to the contents of each notebook, including the range of years in each, start and end dates, field observers' names or initials, and whether the field notebook includes notes on specific sample collections or research activities. There is a column noting whether and when there was field equipment maintenance, whether the notebooks include sample sites outside Loch Vale watershed (and where), and names of the notebook scanners, proofreaders, and quality assurance evaluators. A map of the locations of all sample sites within Loch Vale and additional long-term sites in Rocky Mountain National Park is included with the field notebook files. This file is titled "AllSitesMap_fieldnotebooksdatarelease.pdf". Historically, USGS researchers recorded field observations in field notebooks, which USGS has collected and stored. These field notebooks continue to inform research. The field notebooks for Loch Vale watershed and other sites in Rocky Mountain National Park include sample collection type by date for long-term biogeochemical and ecological monitoring that took place from 1983-2023 in order to ask questions about ecosystem structure and function and how mountain ecosystems respond to atmospheric deposition, climate variation, and human impact. monitoring, experiments, snow, lake chemistry, hydrology, fire, subalpine forest 19810617 20230919 observed Complete None planned Rocky Mountain National Park -105.9000 -105.4900 40.5500 40.1500 ISO 19115 Topic Category environment inlandWaters climatologyMeteorologyAtmosphere biota USGS ecology limnology hydrology atmospheric deposition water quality weather nitrogen subalpine forest bathymetry USGS Metadata Identifier USGS:6723cba2d34e4f57573e8e45 None Rocky Mountain National Park Sky Pond The Loch Emerald Lake Lake Haiyaha Lake Louise Lake Husted Fern Lake Odessa Lake Glass Lake Andrews Tarn Loch Vale watershed Common Geographic Areas Colorado None.

All private information (such as phone numbers) were removed. A spreadsheet of the contents of each notebook was created with columns describing start and end dates of each notebook observer name(s) or initials, name of the field notebook, purposes, including whether the notebook referred to field equipment maintenance, an "other" column" and columns identifying the names of notebook examiners, notebook scanners, and the reviewer of the quality of each scanned page. The notebooks report on field activities. Most numbers recorded in the notebooks are all also published by the National Atmospheric Deposition Program, by the USGS National Water Information System (NWIS), in individual data releases that accompany publications. These data were all quality-assured prior to their publication. The dataset includes scans of field notebooks recording observations and notes from sample collection and equipment maintenance in Loch Vale watershed and additional field sites in Rocky Mountain National Park, Colorado. Not included in the scans are notes from laboratory processing of samples, analysis or interpretation of the data. Notebooks were ordered from oldest to youngest. There was some overlap in dates in early notebooks; the earliest date where information was recorded was used as the start date. Meetings held with USGS Data Preservation and Core Science Systems personnel confirmed that pages from field notebooks could be digitized and do not need to be transcribed and made 508 compliant. All pages were scanned on a XEROX AltaLink Model C8055 copy machine at the Natural Resource Ecology Laboratory, Colorado State University. Scanning took place from August 2023 to March 2024. The scanning surface was wiped clean Notebook pages were each scanned at 600 pixels per inch. With guidance from Kelly Haberstroh, USGS Digitization Librarian, we scanned each page as uncompressed TIFF files. Each page was aligned on the scanner as straight as possible in order to minimize skewing. A border of 0.5 inch was maintained so as not to lose information. The front cover, every double page, and back cover of each notebook was scanned. Each scan became a .tif file that was stored in individual folders on a shared drive identified by the start and end dates of each notebook. Each page was reviewed; pages that were tilted or difficult to read were re-scanned. All .tif files were numbered sequentially from front to back (example: LVWS_NB23_50.tif is Loch Vale watershed_notebook23_page50.tif). All pages were screened for personal information and where found, were covered with tape and re-scanned. TIFF files for each notebook were combined to make one PDF for each field notebook using Adobe Acrobat Pro. These are the notebooks shared in this metadata. Notebooks are labeled FieldBookStartDate_EndDate.pdf. Start and end dates are formatted as YYMMDD (yearyearmonthmonthdayday). Twelve field notebooks were too large to combine into one PDF file; these were separated into smaller PDF files with a suffix of _p1 or _p2, or in two cases _p3. A tabular file was created documenting basic information in each notebook. This file, labeled FieldNotebookContents, includes rows for each notebook that includes the years during which the notebook was used, the actual dates of use, observer name/initials, the name of the PDF file with the scanned pages, columns describing what was collected (example: weather observations yes or no), whether there was field equipment maintenance and what kind, a column labeled "Other" for non-routine sample locations, observations or measurements, and four columns for quality assurance. 20240903 Kelly Haberstroh USGS Library Digitization Librarian mailing and physical
