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 2011and 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 data set contains the results of ocean acidification analyses of water samples collected in the northeastern Chukchi Sea. Samples were analyzed for dissolved inorganic carbon and total alkalinity and used to calculate the pH, partial pressure of carbon dioxide, and carbonate mineral saturation states for calcite and aragonite in the water column. The parameters for this data set include the latitude and longitude of the location the sample was collected; the local date of sample collection; the depth of the water where the sample was collected; the amount of dissolved inorganic carbon , the total alkalinity, the pH, and the partial pressure of carbon dioxide in the sample; the saturation state of calcite and aragonite in the sample; the title of the report the data set supports; the name of the contractor who recorded and analyzed the data; and any additional notes concerning the sample.

Purpose:

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

Attribute_Accuracy_Report:

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.

Logical_Consistency_Report:

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.

Horizontal_Positional_Accuracy_Report:

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.
