Public release of DART database to our new Linux / PostgreSQL system, which improves both the speed and reliability of the website services.

In March 2015, DART made publicly available our new Linux / PostgreSQL system. The migration of DART away from a 20 year legacy UNIX / Ingres environment has resulted in some changes to the underlying datasets used by DART for data publication and analysis. These changes are the result of two different processes.

For PTAGIS data, the restructuring of data tables to accommodate the completely available dataset from the primary source allows us to present the entire event dataset and synchronize on a daily basis. DART will now present the entire fish observation histories (versus first and last site detection) and provide better coverage of passage histories. This change in the underlying data may result in slightly different results for survival, travel time and conversion rate analyses as well as slight changes in DART’s life stage filter that assigns PTAGIS observations to juvenile and adult events.

For other datasets, the entire record was retrieved from the primary source. In some cases, this duplicates the data in DART’s previous version.

  • For NOAA’s buoy data, PFEL’s upwelling indices, FPC’s Transportation numbers and Hatchery Release listings, the entire period of record was re-obtained from the primary sources and loaded into DART’s database.
  • Hourly water quality and river environment data was transferred from the original DART database and is being updated daily from USACE online sources. There should be no changes observed in these datasets.

For a few datasets, the retrieval of the historical record has resulted in updates to a larger number of data rows.

  • In particular, FPC’s complete smolt index dataset has been retrieved from FPC resulting in numerous changes to the data previously imported into DART via the “Two Week Passage Index” text files.
  • The USACE adult passage data has also undergone a significant level of revision. The FCRPS adult passage counts were updated in their entirety (1938-2014) to reflect the daily numbers currently reported online by the US Army Corps Portland District.

For automated data retrieval with scripts, please contact us for help in updating your retrieval scripts. Any script using a URL referencing "/cgi-bin/dart" to retrieve data from DART will need to be updated.

11/1/2011

DART is working closely with the ISEMP project and Washington Department of Fish and Wildlife to provide data queries for managers and scientists to access information associated with tributary PIT tag releases and subsequent tributary/mainstem detections. These queries are intended to assist a user to combine data from multiple detection types (recapture files, instream PIT detection sites, mainstem interrogation sites, etc.) and inform the user of the capture and migration histories, both in-basin and out-of-basin, allowing for more efficient/standardized analysis.

DART Columbia Basin Instream Arrays & Subbasins with Interrogation and Recapture datasets

Researchers across the Columbia Basin have rapidly expanded efforts to deploy remote PIT tag detection arrays in tributary basins, providing an opportunity to observe movement and life history patterns of individual fish in greater detail. In order to standardize the efficient handling and analysis of these datasets for both juvenile and adult populations for specific research questions and to allow reproducible results across research studies, DART developed these web-based analytical processing tools fully aggregating the subbasin interrogation sites with recapture datasets. These tools provide detail and summary data for specific subbasins as well as metadata and methods for observation patterns, travel time statistics, straying, kelt migration, and ghost tag identification.

DART PIT Tag Adult Sampling and Tagging at Ladders Valid Sample List and Sample Time/Rates

The DART PIT Tag Adult Sampling and Tagging at Ladders, specifically Lower Granite Dam Ladder trap, allows users to identify PIT tagged fish associated the ISEMP steelhead and spring/summer Chinook salmon adult PIT tagging project. These tags are used to generate escapement estimates in tributary streams upstream of the detection location. Because the LGR Ladder trap has multiple users and objectives, it can be difficult to identify the PIT tags associated with the systematic sample due to trap operations (e.g. adult Sort-by-Code actions). The trap at Lower Granite Dam is computer controlled and systematically opens four times an hour at a specific rate (e.g. 10% of a 24 hour period). However, if a PIT tagged fish passing the trap is targeted for sampling associated with another project (Sort-by-Code), that fish could be collected outside the systematic sampling period. Since these SbyC fish are not a random sample (all sampling period and SbyC fish are collected in one box and trap personnel can not separate out when they were collected), they are not considered part of the tag list (Valid Sample List) used for upstream escapement calculations.

To ensure all users of the adult PIT tagging project have the same "Valid Sample List", DART created a query to identify all tagged and recaptured fish at the trap associated with the trap operations, and parse these fish into a real-time accessible list. Before this query, the list was created by hand and it was difficult to provide a list in a timely fashion to all cooperators and users, and ensure that users had the most up-to-date version.

Additionally, DART has created a query to summarize trap operations, specifically opening and closing times, total sample time by day, trap open times associated with the SbyC process, and the resulting numbers of recaptured fish collected by the sampling or SbyC process. From this information, the percent of time sampled can be calculated and used to inform the tributary escapement calculations.

07/05/2011

4 Year Average passage to date calculations have been corrected in the Adult Passage Project Summary results to properly correspond to stated Chinook Run Date Ranges.

04/28/2011

Last Year passage to date and 4 Year Average passage to date have been added to the Adult Passage Project Summary report summary table for all species counted in the current year at the select project. The summary table also includes cumulative passage to date, 10 Year Average passage to date, current passage percent of the 10 Year Average, run complete date. The summary table contains links to the 10 Year Run Timing graphs, Cumulative Passage with 10 Year Average graph, and 4 Year Rolling Mean graph.

javaDART 2.0 is a new Columbia River DART database access tool based on the java programming language. It runs within a web page as an applet giving users greater flexibility to extract and analyze data from DART in both graphical and text-based formats. javaDART provides access to the River Environment, Adult Passage, and Juvenile Passage data sets. Plotting multiple data types in a single graph is possible with javaDART, which supports up to four separate Y axes. Graphs can be configured with axis scaling options including zoom in and zoom out capabilities for each axis as well as a round axis function that uses an adaptive rounding algorithm to create readable axis value labels. Graphs may be saved or exported to number of popular formats or copied to the system clipboard. With the text data interface, users can specify which columns to be copied or saved to disk. The text view handles both Julian dates and a standard date format. javaDART data analysis functions include parameter versus parameter (XY) plots and linear regressions on data series pairs. Regression lines and statistics are displayed on the graphs. Data filtering algorithms are a powerful data analysis feature of javaDART that can identify and remove erroneous data that sometimes occur in data queries. The user can easily control the amount of filtering using a redesigned filtering interface with slider controls. In addition, javaDART offers data accumulation; histogram options by weeks, months, or years; and plotting multiple years consecutively or as individual years.

DART provides two types of water temperature data. One is the scrollcase data taken from inside the project structure. The other is the water column temperatures observed at the Water Quality Monitoring (WQM) probes generally at about 15 feet deep in the forebays and tailraces of the projects. In the past, these two data sets were merged into one with pre-1995 data exclusively scrollcase and post-1994 data exclusively WQM. These two data sets are now separated. Both temperature data sets can be queried from the River Environment web pages: "Temperature (Scroll Case)" for scroll case and "Temperature (WQM)" for water quality monitor.
