What does this data set describe?

Title:
Ambient Noise Spectra Plot Catalog from Passive Acoustic Data, NE Chukchi Sea, 2007-2012
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. Throughout the entire program, passive acoustic data collection targeted a larger area extending from Cape Lisburne to Barrow out to approximately 100 nautical miles.
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 data set contains descriptions of ambient noise spectra plots created from acoustic data collected in the northeastern Chukchi Sea during the open water season from 2007 to 2012. The data parameters include the acoustic recorder ID, the name of the spectra plot, a description of the spectra plot, the dates and times the acoustic recorder started and stopped recording, the study year, the title of the annual report the data set supports, the name of the contractor who collected the data, and notes about the acoustic recorder. The related data set entitled Passive Acoustic Acquisition, NE Chukchi Sea, 2009-2012 contains recorder information and mooring locations.
Supplemental_Information:
Edition 4 Updates (November 2013): Appended 2012 data, incorporated PI edits and added keywords.
Edition 3 Updates (August 2013): No changes, resubmitting to AOOS so all passive acoustic data are same edition. Incorporated PI edits.
Edition 2 Updates (February 2013): Appended 2011 data, updated metadata to include details about 2011 season, geographic projection updated from NAD83 to WGS84.

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 was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    Date: Unknown (process 1 of 1)
    No process steps have been described for this data set

  3. What similar or related data should the user be aware of?


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

  1. How well have the observations been checked?

  2. How accurate are the geographic locations?

    From 2009 on, latitude and longitude values were obtained through a Hemisphere VS100 Heading and Positioning Receiver on the Westward Wind. 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?

    This data set includes supporting documents which constists of a series of sound files and spectrogram image files.

  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.
