What does this data set describe?

Title: Microplankton Biomass, NE Chukchi Sea, 2012
Abstract:
This data set was collected as part of the Chukchi Sea Environmental Studies Program (CSESP), a multi-year, interdisciplinary ecological study focused on areas in outer continental shelf oil and gas leases in the northeastern Chukchi Sea. In 2008 when the program began, two 30 x 30 nautical mile study area boxes were developed around areas of interest to ConocoPhillips and Shell. The ConocoPhillips study area (named Klondike), and the Shell study area (named Burger) became the focus of data collection. Data were collected from these two study areas again in 2009. Then, in 2010, Statoil joined the program, and a third study area, Statoil, was created and sampled as well as Klondike and Burger. In 2011 and 2012, the scope of the study area was expanded to include the Hanna Shoal Regional Study Area.
The CSESP interdisciplinary studies include acoustic monitoring, baseline chemistry, benthic ecology, chemical oceanography, fisheries ecology, marine mammal ecology, physical oceanography, plankton ecology and nutrients, and seabird ecology.
This dataset contains microplankton biomass data collected in the northeastern Chukchi Sea during the open water seasons in 2012. The parameters for this data set include the cruise ID; station ID; the latitude and longitude of the location the sample was collected; the local date and time of sample collection; the average depth of water; the microplankton biomass in micrograms carbon per liter of seawater; the contractor who recorded and analyzed the data; the title of the annual report the data set supports and any additional notes concerning the sample.

Why was the data set created?

The objectives of the Chukchi Sea Environmental Baseline Studies Program are: 1. To provide data for pre-exploration and development-related activities 2. To provide data for permit applications 3. To provide input to planning of future operations and associated mitigation 4. To provide additional baseline data that can be used to assess and measure the potential environmental effects of offshore oil and gas exploration and development in the northeastern Chukchi Sea

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    CSESP Attribute Accuracy Overview When the program began in 2008, scientists collected and stored their data through a variety of methods. Vessel data were collected by individual software packages and backed up as part of the regular computer backups, which may or may not have coincided with backups conducted by the scientists. Each scientist had his or her own method for recording and storing at sea observations and data; some of these methods included paper copies.
    The TigerSoft application was developed in 2009 to better manage all scientific data collected through the CSESP. TigerSoft consists of three components: TigerObserver, TigerNav, and TigerObserver Server. Under the oversight of a data manager, these three programs worked in concert with predetermined scientific data protocols to integrate scientific observations with vessel navigation to produce standardized data sets. Data sets were backed up regularly and made available to scientists to proof and edit on a nightly basis during the cruises. TigerSoft was used each season for data collection since it's inception in 2009.
    After the conclusion of each field season, data managers merged the TigerSoft daily observation databases of each discipline and distributed the data in Excel spreadsheet format to the primary investigators of each discipline. Primary investigators reviewed their data and signed forms acknowledging the completeness and accuracy of the data. If corrections needed to be made to the data, detailed information regarding the corrections and an edited copy of the data was returned to the data manager. Examples of corrections include updated species identification and deletion of an observation event that was made in error.

  2. How accurate are the geographic locations?

    Since 2009, latitude and longitude values were obtained through a Hemisphere VS100 Heading and Positioning Receiver. The horizontal accuracy of the instrument was +/- 0.6 meters.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

  5. How consistent are the relationships among the observations, including topology?

    Each year the primary investigators spent approximately nine months analyzing their data and then produced a discipline specific annual report for CSESP and a final data set. The final data had to adhere to a predetermined data protocol and pass through a data validation tool in order to be accepted by the data manager. Data that did not pass validation were returned to the primary investigators to be corrected and resubmitted for validation.
